Effects of habitat fragmentation on species richness and community composition of medium- and large-sized mammals in sugarcane-dominated Cerrado landscapes, southwestern Goiás, Brazil
Mammal species richness and community composition in the Cerrado Protected Areas of Chapada dos Veadeiros and Emas National Parks, Brazil, are highly sensitive to habitat fragmentation caused by sugarcane expansion. The study found that landscape metrics—such as native habitat area, fragment isolation, and proximity to protected areas—explained 90.1% of species richness variation and 85.5% of compositional changes. Species diversity increased with more native habitat but declined with greater fragment isolation, while community structure was primarily shaped by inter-fragment distances and protection status. These findings highlight the profound impact of agricultural landscapes on mammal assemblages, favoring generalist and disturbance-tolerant species while reshaping ecological dynamics.
Immunological and reproductive effects of anthropized environments in Leptodactylus fuscus (Anura)
Anthropogenic disturbances in the Cerrado Protected Areas, specifically Chapada dos Veadeiros and Emas National Parks, significantly alter the immunological and reproductive systems of the frog Leptodactylus fuscus. Research indicates that exposure to agricultural (soybean and sugarcane) and urban environments leads to increased lymphocyte and neutrophil counts, reduced spleen white pulp, elevated red pulp, higher mast cell presence, and changes in melanin pigmentation. Additionally, frogs from highly disturbed areas show an expansion in the area occupied by spermatogonia, spermatocytes, spermatids, and spermatozoa, suggesting multi-systemic physiological adaptations or stress responses. This study highlights the potential of tissue biomarkers for monitoring wild populations under environmental stress, providing critical insights into the impacts of anthropogenic activities on native anuran communities.
Soil Macrofauna Diversity in Threatened Veredas in Two Protected Areas of the Brazilian Cerrado
Environmental degradation in veredas, hygrophilous communities of the Brazilian Cerrado, does not necessarily reduce soil macrofauna diversity but instead may favor certain functional groups, such as herbivores and detritivores, which adapt to altered conditions. This restructuring of communities, rather than a simple decline in biodiversity, was observed in a study comparing preserved (Almescla) and degraded (Peruaçu) veredas in northern Minas Gerais. Researchers analyzed soil macrofauna using pitfall traps across 24 plots per site, recording over 5000 arthropod individuals belonging to four classes, 20 orders, 89 families, and 396 morphospecies. Ants (Formicidae) were the most abundant group, influencing higher macrofauna occurrence in degraded areas due to their adaptability. The study underscores the importance of conservation efforts to maintain vegetation structure and litter deposition, ensuring the preservation of soil biodiversity in threatened ecosystems.
Spatial and temporal variation in food resources shapes foraging of the Blue-and-yellow Macaw (Ara ararauna; Linnaeus, 1758) in a mosaic of Cerrado densities
Blue-and-yellow Macaws (Ara ararauna) rely on the spatial and temporal variation of food resources across different densities of Cerrado habitats for their survival. Research at Emas National Park, Brazil, revealed that three key food species—Anacardium humile, Caryocar brasiliense, and Ouratea spectabilis—vary significantly in abundance depending on Cerrado density, with open sites supporting higher numbers of macaws during the dry-to-wet season transition. Pouteria torta serves as a consistent seed source across all densities. The study highlights that conserving diverse Cerrado mosaics is critical for maintaining year-round food availability and sustaining macaw populations amid habitat loss.
Temporal Changes in Vegetation Cover in Área de Proteção de Pouso Alto, Chapada dos Veadeiros - GO
Despite the establishment of the Área de Proteção Ambiental (APA) de Pouso Alto in 2001, vegetation loss in the Chapada dos Veadeiros region has not been effectively mitigated. A study analyzing land cover changes over 23 years found that 27.8% of the APA experienced alterations, with 16.6% occurring post-protection designation. Critically, the wilderness zone—intended to have stricter protections—showed nearly triple the vegetation loss in 2023 compared to 2000. The failure to implement a management plan has left priority conservation areas vulnerable, undermining the APA's role in landscape protection and connectivity. Researchers used MapBiomas classification data to compare land use between 2000 (pre-APA) and 2023, revealing persistent threats to biodiversity despite legal safeguards.

Conducted through semi-structured interviews with 10 spiritual travelers in Alto Paraíso, the research applies 'push and pull' motivation theory to analyze data via MAXQDA software. Findings underscore the need for sustainable development of spiritual tourism in this protected area, balancing cultural preservation with visitor experiences.
Effects of Precipitation and Fire on Land Surface Phenology in the Brazilian Savannas (Cerrado)
Fire and precipitation significantly influence land surface phenology (LSP) in the Brazilian Cerrado, with fire exerting a stronger impact on vegetation recovery metrics. A study analyzing Emas National Park using MODIS and HLS satellite data identified key LSP metrics—such as Amplitude (AMP), End of Season (EOS), and Seasonal Integrals (SSI)—that are highly responsive to both rainfall and fire disturbances. While precipitation primarily affects woodland areas, fire disrupts grasslands more severely, altering Base Level (BL) and recovery rates post-disturbance. The research highlights the importance of combining high-resolution satellite data to better understand vegetation dynamics in this globally significant ecosystem.
Spatiotemporal Analysis of Land Use and Cover Dynamics in Protected Areas of the Brazilian Cerrado
Protected areas within the Brazilian Cerrado, such as Chapada dos Veadeiros and Emas National Parks, exhibit significantly more constrained land use and cover dynamics compared to their buffer zones (BZs), with some parks like Templo dos Pilares showing extensive preserved vegetation. However, surrounding BZs face intense land use pressures, posing potential threats to biodiversity conservation in these protected areas. A spatiotemporal analysis of satellite imagery from 1985 to 2018 revealed that while NPA maintain stable land cover patterns, their BZs experience rapid transformations, highlighting the need for proactive management strategies to mitigate external pressures and safeguard long-term conservation efforts.
The long-term absence of natural fires restructures the small-bodied mammal assemblages across a Protected Area of Brazilian Cerrado
Long-term absence of natural fires (17 years) significantly restructured small-bodied mammal assemblages in the Cerrado Protected Areas, leading to habitat homogenization and shifts in species composition. The study compared data from 2016–2017 (no fires) with 1999–2000 (fires present), revealing that most species adapted to both forest and savannah environments, unlike the distinct assemblages observed during natural fire regimes. This suggests fire absence alters local biodiversity dynamics, emphasizing its critical role in maintaining Cerrado ecosystems. The findings underscore the need for nuanced fire management strategies to preserve native biotas, as both excessive fires and their complete suppression negatively impact mammal communities.

The environmental triangle of the Cerrado Domain: Ecological factors driving shifts in tree species composition between forests and savannas
Researchers propose the 'Cerrado Vegetation Triangle,' a novel model that characterizes woody vegetation in Brazil's Cerrado Domain based on tree species composition and ecological drivers. The study analyzed 1,165 inventories across six vegetation types—woody savannas, dystrophic cerradão, mesotrophic cerradão, seasonally dry tropical forests, semideciduous forests, and evergreen forests—and found three distinct extremes: high-water-availability forests (semideciduous and evergreen), fertile-soil forests (seasonally dry tropical), and poor-soil savannas. Mesotrophic cerradão acts as a transitional type. The findings underscore the role of local substrate heterogeneity and fire history in shaping vegetation mosaics, offering insights for conservation under environmental change.
The Year 2017: Megafires and Management in the Cerrado
In 2017, the Cerrado region of Brazil experienced severe megafires, with 78% of Chapada dos Veadeiros National Park and 85% of Reserva Natural Serra do Tombador burned due to long-standing 'zero-fire' policies. Contrastingly, protected areas implementing Integrate Fire Management (IFM) since 2014 avoided such catastrophic fires, suggesting IFM effectively mitigates wildfire risks. The study compared burned areas and fire scars between sites with IFM and those without, revealing that fire exclusion policies lead to fuel accumulation and increased megafire susceptibility. Findings advocate for re-evaluating fire management strategies in Cerrado protected areas to balance wildfire prevention and biodiversity conservation, particularly where savanna physiognomies dominate.

Additionally, strategic expansion of protected areas and trading environmental reserve quotas could further bolster conservation efforts. This is the first assessment evaluating the impacts of the Forest Code on biodiversity and ecosystem services across 200 million hectares of the Cerrado, highlighting both challenges and opportunities for compliance.
Does season affect fire behaviour in the Cerrado?
Fire season does not significantly influence fire behavior or intensity in the Cerrado's protected areas, such as Chapada dos Veadeiros and Emas National Parks, contrary to initial hypotheses. The study found that fire intensity is primarily driven by the combination of dead biomass proportion and total fuel load, rather than the timing within the dry season. Researchers compared fire parameters across early, mid-, and late dry seasons, evaluating factors like dead fuel percentage, fuel moisture content, and fuel load. Surprisingly, even in areas with two years of fire exclusion, seasonal variations did not affect fire behavior. Instead, flame height was best explained by dead fuel percentage and fuel moisture content. This insight challenges conventional beliefs about fire management strategies, suggesting that biomass accumulation, rather than seasonality, is the critical factor in controlling fire intensity.
Fire Management for Biological Conservation in the Brazilian Cerrado
Fire is integral to the ecological dynamics of the Cerrado, a unique savanna ecosystem in Brazil's Central Plateau.

Research in the Cerrado Protected Areas of Chapada dos Veadeiros and Emas National Parks, Brazil, identified four new species of Piperaceae, contributing significantly to the region's biodiversity. The study focused on Capões de Mata (isolated forest patches) and Mata de Galeria (gallery forests), documenting a total of 11 species—seven from the genus Piper and four from Peperomia. It included an identification key, distribution notes, and photographs to aid taxonomy. This work expands the known flora of the Cerrado biome, particularly in understudied protected areas.
Resource availability shapes fire‐filtered savannas
Resource availability, particularly water and nutrient levels mediated by soil clay content, plays a pivotal role in shaping the functional and phylogenetic structure of fire-filtered savanna communities. The study, conducted in Emas National Park within Brazil's Cerrado biome, found that these resource gradients drive spatial community turnover, with soil texture accounting for the largest fraction of this structure. Additionally, factors such as soil nitrogen availability, pH, altitude, and fire frequency interact to influence community attributes, including species trait values. The research combined individual-based functional trait data, phylogenetic information, and environmental variables using Mantel correlograms and maximum rank correlation approaches to assess these dynamics across a large savanna landscape.
The Brazilian Cerrado: assessment of water and soil degradation in catchments under intensive agricultural use
Intensive agricultural use in the Brazilian Cerrado, one of the world's most threatened biomes, has significantly degraded soil and water quality. A comprehensive review of 80 soil and 18 water studies revealed that land conversion to cash crops led to marked changes in soil pH, bulk density, and nutrient availability, particularly phosphorus (P) and potassium (K), while nitrogen (N) levels remained stable due to the prevalence of nitrogen-fixing soybeans. Water quality studies highlighted nitrogen enrichment in agricultural catchments, indicating potential eutrophication risks. Phosphorus was consistently absent from soils due to high weathering rates, but pesticides were detected throughout aquatic systems, often exceeding Brazilian and EU water quality limits, posing serious health implications. The study warns that ongoing land use intensification, exacerbated by projected droughts, will further degrade soil and water resources, threatening both agricultural productivity and ecosystem stability in the Cerrado.
Trends in water balance components across the Brazilian Cerrado
Significant increases in evapotranspiration, terrestrial water storage, and runoff decreases have been observed across the Brazilian Cerrado from 2003 to 2010. The study leverages remotely sensed data—precipitation (TRMM), evapotranspiration (MOD16), and terrestrial water storage (GRACE)—to assess trends in the region's water balance. By evaluating budget closure with measured discharge data and applying the Mann-Kendall test, researchers identified a 51 ± 15 mm/year rise in annual evapotranspiration, a 11 ± 6 mm/year increase in terrestrial water storage in the northeast Cerrado, and a 72 ± 11 mm/year decline in runoff in isolated areas of Mato Grosso. While uncertainties persist due to data limitations, this approach offers valuable insights into large-scale water balance dynamics, dry periods, and land-use impacts on hydrology.

The study employed morphological traits to classify the species and provides a key for identifying other members of this section. The narrowly endemic nature of M. kalungae underscores its ecological significance and the need for conservation efforts in this UNESCO World Heritage Site.
Análise do potencial de conectividade na região das propriedades rurais do entorno do Parque Nacional das Emas (GO/MS)
Research reveals that the Emas National Park, despite being surrounded by intensive agricultural lands, plays a critical role in conserving key landscape elements beyond its borders. The study found that the park's conservation function extends to adjacent rural properties due to intrinsic relationships between agricultural occupation patterns and physical landscape attributes. By analyzing connectivity potential across these properties, the research highlights the park's importance as a buffer for biodiversity in the Cerrado domain, one of Brazil's most threatened biomes.
Conservation polices and control of habitat fragmentation in the Brazilian Cerrado biome
Only 3.1% of the Brazilian Cerrado biome—one of the planet’s most biodiverse yet threatened savannahs—lies within fully protected areas, highlighting severe gaps in conservation efforts. Despite intense habitat fragmentation and significant loss (48.2%) of original floral cover, governmental and non-governmental measures show limited effectiveness due to resource duplication, over-reliance on international funding, and lack of integration with private landowners or economic incentives. While public agencies dominate conservation planning, field actions remain underdeveloped, emphasizing the need for targeted policies that engage governments, civil society, and farmers to enhance connectivity and protect remaining native vegetation.
Disequilibrium and hyperdynamic tree turnover at the forest–cerrado transition zone in southern Amazonia
The transition zone (ZOT) between the Cerrado and Amazon forest in southern Amazonia exhibits significantly higher tree turnover rates compared to core Amazonian forests, with mortality and recruitment rates of 2.8% and 6.5% per year for trees with diameters ≥10 cm, respectively. This hyperdynamic behavior contrasts sharply with the more stable dynamics (1–2% per year) observed in core Amazonian forests. The study, spanning from 1996 to 2010 across seven vegetation types—including monodominant forest, semi-deciduous seasonal forest, gallery forest, and cerradão—revealed that smaller trees (5 ≤ d < 10 cm) contributed minimally to biomass but had even higher mortality rates (7.4% per year). The findings underscore the unique ecological dynamics of this rapidly shrinking region, necessitating long-term monitoring to assess its response to climate change.
Diversity, activity patterns, and habitat use of the snake fauna of Chapada dos Veadeiros National Park in Central Brazil
Chapada dos Veadeiros National Park (CVNP) in central Brazil harbors one of the richest snake faunas among South American open biomes, with 47 species documented from seven families. The study, conducted between 2006 and 2009, revealed that snake incidence is highly seasonal, primarily associated with rainfall, and daily activity patterns vary significantly, with most species being strictly diurnal while others are nocturnal or crepuscular. Species richness estimators suggest the park may contain even more snake diversity than initially documented. The research provides critical insights into the biodiversity and ecological dynamics of this UNESCO-listed protected area, emphasizing its importance for conservation efforts in the Cerrado biome.
Modelando a expansão da gramínea invasora Brachiaria spp. em uma unidade de conservação
A study on the expansion of the invasive grass Brachiaria spp. in Emas National Park, a critical UNESCO World Heritage Site in Brazil's Cerrado biome, reveals that internal roads and light availability are key drivers of its spread. The research found that vehicle traffic along these roads increases Brachiaria abundance tenfold compared to restricted-access areas, while open vegetation types like Campo Limpo are up to 20 times more susceptible to invasion than forested areas. Subtle slopes (around 1 degree) also direct grass expansion toward lower elevations. Using spatial-temporal data from 2002 and 2012, cellular automaton models linked these patterns to environmental variables, suggesting targeted management strategies such as road use restrictions, phytosanitary measures for visitors, and prioritization of control in open areas and declivities. This work provides actionable insights for mitigating invasive species impacts in protected areas.
Protected Area Effectiveness in Reducing Conversion in a Rapidly Vanishing Ecosystem: The Brazilian Cerrado
Protected areas (PAs) and indigenous lands (ILs) in the Brazilian Cerrado significantly reduce habitat conversion compared to unprotected sites, with strictly protected PAs being more effective than multiple-use PAs. A study analyzing data from 2002 to 2009 found that both PA types and ILs experienced lower conversion rates when matched with similarly exposed unprotected areas. Strictly protected PAs, despite having similar baseline conversion rates as multiple-use PAs, demonstrated greater effectiveness in reducing habitat loss, likely due to stricter land-use regulations. Indigenous lands also showed strong effectiveness, though their baseline conversion rates were high. This research underscores the importance of differentiating PA categories and highlights the potential for increased conservation investments in this rapidly vanishing ecosystem.
Riqueza de espécies e diversidade de Marchantiophyta (hepáticas) de capões de mata, no parque nacional da chapada dos veadeiros, Goiás, Brasil
A comprehensive survey of liverworts (Marchantiophyta) in the 'capões de mata' forest patches within Chapada dos Veadeiros National Park, a UNESCO World Heritage Site in Brazil's Cerrado biome, revealed 36 species across 11 families. Notably, six species represent new records for Brazil's Central-West region and eight are first occurrences for Goiás state. Lejeuneaceae (15 spp.) and Frullaniaceae (five spp.) dominated the diversity, accounting for 54% of the total. All identified species are also found in the Atlantic Forest biome, with significant overlap in the Amazon (66%), Pantanal (44%), Caatinga (22%), and Pampas (11%). None of the species are listed as threatened by the IUCN. The study utilized field surveys to document liverwort richness and diversity, contributing critical baseline data for conservation efforts in this globally significant protected area.
Soil Carbon Stocks under Productive and Degraded Brachiaria Pastures in the Brazilian Cerrado
Soil carbon stocks under productive Brachiaria pastures in the Brazilian Cerrado are significantly higher than those under native vegetation, with differences ranging from 6 to 47 Mg C ha⁻¹ depending on soil clay content. This study compared soil carbon stocks across four sites using chronosequences, evaluating pasture productivity through forage regrowth, litter, and light fraction of soil organic matter (SOM). Soil 13C abundance and C:N ratios indicated that SOM derived from native vegetation persisted at low rates, while degraded pastures showed intermediate or similar carbon stocks to native vegetation. The findings highlight the impact of pasture establishment on soil carbon dynamics, with clay content playing a crucial role in carbon storage.
Trabalho de Campo Integrado em Geografia: uma Experiência no Parque Nacional Chapada dos Veadeiros, Goiás
An integrated fieldwork approach in the UNESCO-listed Chapada dos Veadeiros National Park, Brazil, demonstrates the effectiveness of cross-disciplinary teaching in bridging theory and practice while addressing complex socio-environmental interactions. The study, involving students from multiple geography disciplines—Geomorphology, Biogeography, Cultural Geography, Agrarian Geography, and Thematic Cartography—highlighted how fieldwork fosters holistic analysis by integrating physical, cultural, and agrarian aspects of the park's landscape. Conducted in two phases (classroom preparation and on-site data collection), this methodology not only enhanced students' understanding but also provided a framework for analyzing interrelated environmental and social dynamics within protected areas.
White-lipped peccary home-range size in a protected area and farmland in the central Brazilian grasslands
White-lipped peccaries (Tayassu pecari) require expansive home ranges to persist, yet their adaptability to heterogeneous landscapes remains poorly understood. This study reveals that 13 groups of white-lipped peccaries in the Emas National Park and surrounding farmland exhibited average home-range sizes of 790–8,659 ha, with no correlation to group size or monitoring duration. Home ranges were significantly larger during the wet season than the dry season, likely due to seasonal landscape dynamics, including crop plantations. While peccaries thrived in this mixed-use environment, their overlap with agricultural areas poses conservation challenges, particularly from sugarcane expansion and crop damage conflicts. These findings underscore the need for targeted strategies to mitigate human-wildlife interactions while preserving critical habitats.
A new karyotype for the spiny rat Clyomys laticeps (Thomas, 1909) (Rodentia, Echimyidae) from Central Brazil
Researchers have uncovered a new karyotype for the spiny rat, Clyomys laticeps, a semifossorial rodent endemic to the tropical savannas and grasslands of central Brazil. Analyzing four specimens from Emas National Park in Goiás, Brazil, the study revealed a diploid number (2n) of 32 chromosomes and a fundamental autosome number (FN) of 54. The karyotype features 12 meta/submetacentric pairs and three acrocentric pairs, with the X chromosome being medium submetacentric and the Y chromosome medium acrocentric. Cytogenetic techniques such as conventional staining, CBG, and GTG-banding were employed to characterize these chromosomal structures. The findings suggest that the semifossorial habits and habitat specificity of this genus may contribute to observed karyological variations.
Anuran Species Composition and Distribution Patterns in Brazilian Cerrado, a Neotropical Hotspot
A comprehensive analysis of anuran amphibian species distribution in the Cerrado, a neotropical hotspot, reveals distinct spatial patterns influenced by adjoining biomes. Among 209 identified species, only 14% are widespread within the Cerrado, while others exhibit highly structured distributions linked to Amazonian, Atlantic, Caatinga, and Chaco domains. Narrow endemics (<60,000 km²) are confined to mountain ranges in central, southeastern, and southwestern regions, underscoring the influence of independent species pools. The study combines extensive fieldwork and zoological collection data to provide an updated species list and hypotheses for future research on species distribution dynamics.

Climatic stability in the Brazilian Cerrado: implications for biogeographical connections of South American savannas, species richness and conservation in a biodiversity hotspot
Research reveals that climatic stability is a stronger predictor of squamate reptile richness in the Brazilian Cerrado than current climate variables, challenging traditional biogeographical assumptions about South American savannas. The study used machine-learning models to project the Cerrado's distribution across four time periods—current, mid-Holocene (6 ka), Last Glacial Maximum (21 ka), and Last Interglacial (120 ka)—and identified two savanna corridors: an eastern coastal corridor during the Last Interglacial and an Andean corridor during the Last Glacial Maximum. Additionally, it predicted a large refugial area in the northeastern Cerrado, suggesting that Bolivian savannas should be included within the Cerrado range, contrary to previous hypotheses linking it to the Chaco and Caatinga biomes. The findings highlight the importance of climatic stability maps for future biodiversity studies and conservation planning.
Evidence for Adaptation to Fire Regimes in the Tropical Savannas of the Brazilian Cerrado
Research challenges the conventional view that fire-resistant traits in Cerrado plants evolved primarily due to drought or nutrient-deficient soils. Instead, it suggests these traits—such as thick bark and root sprouting—are adaptations to fire regimes, supported by phylogenetic evidence showing their emergence coincided with the rise of flammable C4 grasses and savanna expansion. The study highlights that these traits are absent in related lineages from fire-free environments with similar soil conditions, reinforcing their link to fire adaptation. This finding implies a low evolutionary barrier for lineages entering the Cerrado, likely due to the ease of adapting to fire regimes.
Potential impacts of climate change on biogeochemical functioning of Cerrado ecosystems
Climate change is poised to shift the Cerrado savanna from a carbon sink to a source, potentially intensifying fire regimes and reducing nutrient stocks. This study synthesizes data on biogeochemical functioning in Chapada dos Veadeiros and Emas National Parks, revealing that while Cerrado ecosystems currently act as carbon sinks annually, they release CO2 near the end of the dry season due to conservative nutrient cycles dominated by soil organic matter and root systems. Projected increases in temperature, reduced rainfall, and longer dry seasons—particularly in northeastern regions—could exacerbate these dynamics, threatening biodiversity and ecosystem stability. The research highlights the need for new modeling approaches to account for the Cerrado's spatial heterogeneity and land-use changes when projecting climate impacts.

By analyzing oral histories, the study underscores the tensions between conservation goals and local practices, particularly the decline of the Cerrado biome. It provides insight into the social dynamics that have influenced environmental policies in this biodiverse region since the 1960s.
Seasonal Abundance of Hemipterans onCaryocar brasiliense(Malpighiales: Caryocaraceae) Trees in the Cerrado
Research on the seasonal abundance of hemipterans and their predators on Caryocar brasiliense trees in Cerrado Protected Areas reveals a dynamic ecological interaction influenced by plant phenology and weather. The study, conducted over three years across Chapada dos Veadeiros and Emas National Parks, found that while the number of sucking insect individuals remained consistent throughout seasons, species diversity peaked in winter. Predator abundance and diversity also showed seasonal variation, with winter being the most diverse season for both groups. Notably, certain predator species like Crematogaster sp. and Trybonia sp. exhibited significant correlations with the presence of specific hemipteran species, such as Dikrella sp., suggesting a complex interplay between these organisms. The findings highlight the importance of seasonal and phenological factors in shaping insect communities within this protected ecosystem.
A New Species of Utricularia (Lentibulariaceae) from Chapada dos Veadeiros (Central Brazil)
Researchers have identified and described a new species of the carnivorous plant genus Utricularia, named Utricularia densiflora, found in the Chapada dos Veadeiros National Park within Brazil's Cerrado Protected Areas. This discovery is notable for its distinct morphological features, including rudimentary floral buds, sessile glands on the peduncle, and a highly congested inflorescence, which differentiate it from other Utricularia species. The study places U. densiflora in section Oligocista, noting its similarity to U. erectiflora and U. meyeri. Additionally, the researchers provide an identification key for Utricularia species inhabiting the park, contributing valuable taxonomic insights to the region's biodiversity.
Comparação da vegetação arbustivo-arbórea de uma área de cerrado rupestre na Chapada dos Veadeiros, Goiás, e áreas de cerrado sentido restrito do Bioma Cerrado
A study of the rupestrian vegetation in Alto Paraíso de Goiás, within Chapada dos Veadeiros National Park, reveals distinct floristic and structural traits that set it apart from other Cerrado areas. The community, dominated by species adapted to rocky outcrops, exhibits high density (1,977 individuals/ha) and area basal (11.25/m²/ha), largely due to the presence of monocotyledons like Velloziaceae and Arecaceae. Excluding these species reduces density and area basal significantly, highlighting their ecological importance. The study also found low floristic similarity with other Cerrado areas, suggesting unique adaptations in this rupestrian ecosystem. Phytogeographic patterns indicate that altitude, geographic proximity, and adjacency to neighboring biomes (Amazonian Forest, Atlantic Forest, and Caatinga) influence vegetation composition.
Cryptic lineages and Pleistocene population expansion in a Brazilian Cerrado frog
A study of the Brazilian Cerrado frog Hypsiboas albopunctatus reveals cryptic lineages with deep divergences, challenging the perception of the Cerrado as a barrier-free habitat. Phylogenetic analysis identified three distinct lineages: the Chapada dos Guimarães (CG) clade, which diverged in the late Miocene and likely represents a cryptic species; the southeast (SE) clade, associated with historical Atlantic forest distribution; and the Central Cerrado (CC) group, paraphyletic relative to the SE clade. Historical demography analyses suggest significant population expansion in the CC and SE populations, linked to Pleistocene climatic fluctuations and the formation of open habitats. The study highlights the complex diversification history of the Cerrado, a morphoclimatic domain under severe anthropogenic threat, and underscores the likelihood of underestimated biodiversity in this region.
Ecology and conservation of the jaguar (Panthera onca) in the Cerrado grasslands of central Brazil
A study reveals that the jaguar population in Emas National Park (ENP), a critical Cerrado reserve, is highly isolated and vulnerable to extinction due to its small size. Researchers estimated a jaguar density of 0.3-0.6 individuals per 100 km² using camera trapping data and spatially explicit models, which account for animal movement more accurately than traditional methods. The study also found that jaguars in ENP exhibit strong selection for giant anteaters as a primary prey, aligning with an optimal foraging model that predicts this preference due to its profitability. Additionally, the research demonstrated resource partitioning between jaguars and pumas, with jaguars dominating dense habitats within the park while pumas, being more generalist, are frequently found outside ENP boundaries. The findings underscore the urgency of addressing small population isolation and identifying potential dispersal corridors for jaguar conservation in the Cerrado.
Feeding ecology of Ara ararauna (Aves, Psittacidae) at firebreaks in western Cerrado, Brazil
Blue-and-yellow Macaws (Ara ararauna) in the Cerrado Protected Areas of Brazil, particularly Chapada dos Veadeiros and Emas National Parks, are highly attracted to firebreaks due to the abundance of fruiting Anacardium humile shrubs. A study observed 76 macaw flocks foraging at these sites between September 2006 and February 2007, revealing that seeds from A. humile were their primary food source. Macaws also consumed young apical parts, leaves, flowers, and branches of other plant species, with a significant preference for shrubs over trees. Their foraging activities often resulted in damage to reproductive and young plant parts, highlighting the ecological impact of macaw behavior on these protected areas.
Prevalence and Lineage Diversity of Avian Haemosporidians from Three Distinct Cerrado Habitats in Brazil
A study of avian haemosporidian parasites in Brazil's Cerrado Protected Areas revealed that habitat alteration does not significantly impact the prevalence or diversity of Plasmodium and Haemoproteus infections. Researchers analyzed 676 wild birds from three distinct habitats—intact cerrado, disturbed cerrado, and a transition area between Amazonian rainforest and cerrad—to assess how these environments influence parasite dynamics. While no significant differences were found among habitats, the study identified 15 previously unknown parasite lineages, suggesting potential regional endemism. Additionally, six known lineages accounted for 50-80% of infections, indicating a strong regional relationship in parasite distribution.
Prevalence and Molecular Characterization of Mycoplasma ovis in Selected Free-Ranging Brazilian Deer Populations
A study reveals that Mycoplasma ovis, a hemoplasma known to cause anemia and mortality in small ruminants, infects free-ranging deer populations in Brazil with significant prevalence. Analysis of 103 deer samples from Porto Primavera, Pantanal, and Emas National Park identified an overall infection rate of 58%, with the highest prevalence (72%) observed in Blastocerus dichotomus from Porto Primavera. Molecular characterization using PCR and sequencing of the 16S rRNA gene uncovered three genetically distinct hemoplasmas, including M. ovis, 'Candidatus Mycoplasma erythrocervae', and a novel strain closely related to M. ovis. Phylogenetic analysis confirmed these findings, highlighting the genetic diversity of hemoplasmas in wild deer populations.
Resource Selection and Its Implications for Wide-Ranging Mammals of the Brazilian Cerrado
A critical insight from this study is that Emas National Park, despite its small size, provides rare and essential resource conditions for giant armadillos (Priodontes maximus) and jaguars (Panthera onca), making these species highly sensitive to landscape changes caused by agricultural development outside the park. The research used noninvasive methods, including scat detection dogs, to survey five large mammals of conservation concern across 1,572 scat locations and 434 giant armadillo burrow sites. By estimating resource selection probability functions, the study revealed that while natural habitats are crucial for these species, remnants of woodland and forest vegetation enable other wide-ranging mammals like maned wolves (Chrysocyon brachyurus), pumas (Puma concolor), and giant anteaters (Myrmecophaga tridactyla) to utilize agricultural landscapes. The findings underscore the need for a multi-faceted conservation approach that extends beyond park boundaries to protect these species effectively.
The Use of Fire in the Cerrado and Amazonian Rainforests of Brazil: Past and Present
This study highlights the significant impact of human activity on fire regimes in Brazil's Cerrado and Amazon biomes over the past 4000 years, revealing a stark contrast between fire-adapted savannas and fire-sensitive rainforests. It demonstrates that while natural lightning fires are common in savannas, anthropogenic fires now dominate both ecosystems, with post-European settlement fire frequency surging due to cattle ranching and agricultural practices. The research consolidates fragmented data on indigenous fire use and emphasizes the need for distinct fire management strategies to mitigate biodiversity loss and environmental degradation. In the Amazon, policies should promote fire-free small-scale agriculture, while in the Cerrado, sustainable fire use for ranching must align with local conditions. Effective conservation strategies require integrating scientific knowledge with indigenous expertise to maintain ecological processes and reduce destructive wildfires.
Ticks on free-living wild mammals in Emas National Park, Goias State, central Brazil
A comprehensive study of ticks on free-living wild mammals in Emas National Park, Brazil, reveals significant new host-parasite associations. Over nearly a decade (1999–2008), researchers documented nine tick species across multiple mammal orders, including several novel findings: adult Amblyomma tigrinum parasitizing pampas cats (Leopardus colocolo), and nymphs of six tick species on previously unrecorded hosts such as crab-eating foxes (Cerdocyon thous) and other carnivores. While most associations were consistent with prior records, the study expands our understanding of ectoparasite diversity in Brazilian wildlife, highlighting the importance of long-term monitoring in protected areas like Emas National Park.
Unprotecting the rare species: a niche‐based gap analysis for odonates in a core Cerrado area
Current conservation efforts in the Cerrado Protected Areas, specifically Chapada dos Veadeiros and Emas National Parks, fail to adequately protect rare odonate species. The study reveals a direct linear relationship between species range size and protection levels, with wider-ranging species being more likely to be protected than restricted or threatened ones. Using niche-based species distribution models (SDMs), researchers identified critical gaps in the existing conservation network, highlighting three areas of high odonate beta diversity where urgent conservation action is needed. The analysis also demonstrated that raw odonate data without SDM modeling provides limited utility for setting conservation priorities.
Vicariance and endemism in a Neotropical savanna hotspot: distribution patterns of Cerrado squamate reptiles
A groundbreaking study reveals that vicariant speciation, not faunal interchange, has predominantly shaped the diversity of squamate reptiles in the Cerrado, a Neotropical savanna hotspot. The research, which analyzed 267 species—including 103 endemics (39% of total)—challenges long-held assumptions about low endemism in the region. By mapping distribution patterns and testing predictions of the vicariance model, scientists identified seven biotic elements and ten putative areas of endemism, largely coinciding with topographical and vegetational divisions. Open, elevated plateaus emerged as hotspots for endemism, while peripheral depressions exhibited higher faunal interchange. This study underscores the critical role of vicariant processes in driving biodiversity, suggesting their prevalence across the Cerrado and broader Neotropical regions.
A new population of the Cone-billed Tanager Conothraupis mesoleuca, with information on the biology, behaviour and type locality of the species
Researchers have identified a new population of the Critically Endangered Cone-billed Tanager (Conothraupis mesoleuca) in Chapada dos Parecis, Mato Grosso, Brazil. This discovery, based on observations of at least 40 individuals, expands the known range of the species, which was previously thought to be limited to Emas National Park in Goiás. The study provides the first detailed information on the biology and behavior of this elusive bird, including descriptions of its habitat preferences—primarily flooded riverine areas—and the female's morphology. Historical records suggest that the type locality of the species may refer to the Juruena telegraph station, clarifying a long-standing ambiguity. This finding underscores the urgent need for further research on the species' biology and conservation status, given its restricted range and potential habitat availability in the upper Juruena basin.
Analysis of the floristic composition of the Brazilian cerrado vegetation II: Comparison of the woody vegetation of 98 areas
A comprehensive analysis of the floristic composition of 98 areas of Brazilian cerrados and Amazonian savannas revealed significant geographic patterns in woody vegetation distribution. The study identified five distinct regional groups—southern, southeastern, central, central-western, and northern—as well as a disjunct group of Amazonian savannas, demonstrating the biome's extreme heterogeneity. Only 28 species were present across at least half of the sites, while 158 species were unique to single locations. Multivariate analyses, including TWINSPAN, UPGMA, and DCA, consistently showed that soil type (mesotrophic or dystrophic) plays a crucial role in shaping floristic composition. This research underscores the cerrados' complex structure and the importance of regional factors in determining plant diversity.
Detecção de Incêndios Florestais no Parque Nacional da Chapada dos Veadeiros e Área de Entorno
In 2007, fires affected 72.81% of the Parque Nacional da Chapada dos Veadeiros (PNCV) and 38.10% of its surrounding area, with September being the most impacted month. The study, using geotechnologies, identified that Savana Parque (Sp) was the most severely affected land cover type, accounting for 75.78% of burned areas within PNCV. This research highlights the significant impact of wildfires on this UNESCO World Heritage Site and its buffer zone, emphasizing the need for targeted conservation efforts to mitigate fire-related damage in such vulnerable ecosystems.
Disputas pela legitimação de lógicas de uso e apropriação do meio natural:conservação ambiental, representações e conflitos no entorno do Parque Nacional das Emas - GO DOI:10.5007/1807-1384.2010v7n1p37
A study of the Emas National Park, a UNESCO World Heritage Site within the Cerrado Protected Areas, reveals that conflicts over environmental conservation are deeply rooted in cultural meanings and social dynamics rather than solely economic interests. The research, based on field observations, interviews with 51 local agents, and semi-structured techniques, shows how historical conflicts resurface with the introduction of environmental demands, highlighting the tension between traditional land use practices and modern conservation efforts. This finding underscores the importance of understanding cultural narratives in managing protected areas effectively.
Effectiveness of Scat‐Detection Dogs in Determining Species Presence in a Tropical Savanna Landscape
Scat-detection dogs proved highly effective in identifying the presence of five threatened mammal species—maned wolves, pumas, jaguars, giant anteaters, and giant armadillos—in the tropical savanna landscape surrounding Emas National Park, a UNESCO World Heritage Site candidate. The study demonstrated that these canines could reliably detect scat across different seasons, years, and survey team compositions, with detection probabilities varying by species but remaining consistent in methodology. Notably, maned wolves showed the highest occurrence probability (0.91), while jaguars were least detected (0.14), primarily due to their preference for forested areas within the park. The research also revealed that giant armadillos thrived in open grasslands inside the park but shifted to riparian woodlands in agricultural zones. This approach offers a scalable, non-invasive tool for monitoring wide-ranging species even in fragmented habitats, with potential applications beyond the Cerrado ecosystem.
Fire management and the nesting of Athene cunicularia (Aves, Strigidae) in grasslands in central Cerrado, Brazil
Fire management in grasslands of the Cerrado, Brazil, significantly enhances nesting conditions for Burrowing Owls (Athene cunicularia), with firebreaks supporting 19 burrows compared to just one and two in adjacent and distant unmanaged grasslands, respectively. The study, conducted in Emas National Park from October to November 2009, found that frequent burning in firebreaks likely creates more attractive conditions due to the short herbaceous stratum, facilitating successful reproduction with one to three young reaching adult size by early November. Burrows were predominantly single-entrance and associated with termite or ant nests, while sentinel perches for adults included mounds, termite nests, shrubs, and trees, typically under 2 meters high and within 10 meters of the burrow entrance. These findings suggest that fire management can play a crucial role in supporting the reproduction of this species in tropical grasslands.
Hemigrammus tocantinsi: a new species from the upper rio Tocantins basin, Central Brazil (Characiformes: Characidae)
Researchers have identified and described Hemigrammus tocantinsi, a new species of fish from the upper Rio Tocantins basin in Central Brazil. This discovery is notable for several distinguishing features: it possesses 15-17 branched anal-fin rays, a longitudinal stripe that narrows anteriorly and widens posteriorly, and one or two maxillary teeth. The study also highlights sexual dimorphism in this species, characterized by differences in coloration, adipose-fin origin, body measurements, and the presence of bony hooks in the anal and pelvic fins of males. The research contributes to the understanding of biodiversity in the Cerrado Protected Areas, specifically within Chapada dos Veadeiros and Emas National Parks, which are part of UNESCO World Heritage Sites.
Maned wolf survival rate in central Brazil
A first analytically robust estimate of maned wolf survival rates reveals significant temporal fluctuations, with adult survival ranging from 0.28 to 0.97 over a 13-year study in Emas National Park, Brazil. The analysis, using Burnham's live recapture/dead recovery models, found no sex-specific differences but strong evidence for age-related effects, with subadult survival at 0.63. These findings suggest similar mortality risks between adults and subadults and highlight the impact of temporal variability on population dynamics—a critical insight for conservation planning in the threatened Cerrado savannah.
Phylogenetic structure of Brazilian savannas under different fire regimes
Brazilian savannas under high fire frequency exhibit phylogenetic over-dispersion, contrary to expectations that closely related species would dominate fire-prone communities. Instead, these ecosystems host a mix of long-lived resprouting species from diverse lineages, suggesting fire plays a distinct role in structuring plant communities compared to other fire-adapted regions. The study analyzed 801 woody species across central and southeastern Brazilian savannas (including UNESCO-listed Chapada dos Veadeiros and Emas National Parks) and adjacent semi-deciduous seasonal forests, comparing phylogenetic distances between sites with varying fire regimes. Phylogenetic signal analysis revealed evolutionary conservation of life forms, while randomization tests confirmed over-dispersion in high-fire savannas and clustering in low-fire forest sites. These findings challenge traditional models of fire-driven community assembly, highlighting the resilience of phylogenetically diverse species in Brazilian savannas.
Serologic Survey for Selected Infectious Diseases in Free-Ranging Brazilian Tapirs (Tapirus terrestris) in the Cerrado of Central Brazil
A serologic survey conducted between September 2000 and January 2002 in Emas National Park, central Brazil, revealed that free-ranging Brazilian tapirs (Tapirus terrestris) showed no evidence of infection with Leptospira spp., Brucella abortus, or equine infectious anemia. However, one out of ten tapirs tested positive for Toxoplasma gondii, marking the first detection of this pathogen in a wild tapir population in central Brazil. The study involved immobilizing and sampling blood from ten individuals as part of an ecological research effort, providing baseline serological data for infectious diseases in this vulnerable species within the Cerrado biome.
The arboreal ant community visiting extrafloral nectaries in the Neotropical cerrado savanna
A study reveals that the prevalence of ants on Cerrado savanna foliage is driven by abundant, predictable liquid food sources such as extrafloral nectaries (EFNs) and insect honeydew, which significantly promote ant activity. The research demonstrates that while EFN-gathering ants benefit certain plant species by reducing herbivory and enhancing plant fitness, the presence of EFNs does not influence overall ant species richness or composition on a given tree. Contrary to expectations, plants with EFNs attract more ant individuals but do not exhibit lower herbivore numbers at the community level. The study also highlights the role of stem galleries and cavities created by beetles in providing nesting space for arboreal ants. By integrating findings from ant-plant-herbivore interactions, the research suggests new avenues to explore how community-level dynamics shape ant-plant associations in this unique Neotropical ecosystem.
Variability of carbon dioxide flux from tropical (Cerrado) hydroelectric reservoirs
Hydroelectric reservoirs, while generating energy without significant fossil fuel combustion, can emit greenhouse gases (GHGs) at rates comparable to coal or oil-fired systems. A study on five large reservoirs in the Cerrado region of Brazil found that these tropical reservoirs have low CO₂ emissions compared to global averages, but spatial and seasonal variability can lead to over 25% error if ignored. The research evaluated CO₂ concentrations and flux across different zones influenced by flooded biomass, organic matter input, and dam operations, revealing significant heterogeneity in gas emission patterns.
