• High mortality associated with tapeworm parasitism in geladas (Theropithecus gelada) in the Simien Mountains National Park, Ethiopia

  Research reveals that tapeworm parasitism significantly impacts gelada survival and reproduction in Simien National Park, Ethiopia. A decade-long study found high mortality rates among adult females with Taenia serialis cysts, particularly younger adults, while male mortality showed a similar but non-significant trend due to smaller sample sizes. Offspring of infected mothers also experienced increased mortality, primarily due to maternal death. Comparisons with another gelada population suggested that T. serialis may kill hosts more rapidly in Simien National Park. The study highlights the need for further research into individual and population-level heterogeneity in parasite-associated mortality.

• Carbon Storage and Climate Change Mitigation Potential of the Forests of the Simien Mountains National Park, Ethiopia

  A study on Simien Mountains National Park, Ethiopia, reveals a critical trend of deforestation and its impact on carbon storage. The research found that cultivated and overgrazed land (COL) increased from 20% in 1972 to 48% in 2013, leading to a nearly 50% shrinkage of Afro-montane forest (AMF) and Afro-alpine woodland (AAWL). Projections indicate that AAWL could disappear in 71 years while AMF could vanish in just 49 years at the current deforestation rate. The study also quantified carbon storage, with soil organic carbon (SOC) holding 55.2% of the total carbon stock, followed by above-ground carbon (34.4%) and below-ground carbon (8.3%). Notably, no strong relationship was found between biodiversity (Shannon diversity index) and carbon storage in AMF zones. The research used a nested plot design for biomass measurement and satellite imagery analysis to assess land cover changes.

• Habitat preference of the endangered Ethiopian walia ibex (Capra walie) in the Simien Mountains National Park, Ethiopia

  Research reveals that the endangered Ethiopian walia ibex (Capra walie) exhibits a strong preference for rocky and shrubby habitats over herbaceous ones within Simien National Park, Ethiopia. The study, conducted from 2009 to 2011, analyzed pellet distribution and habitat characteristics during wet and dry seasons, finding minimal overlap between walia ibex and livestock presence (70% of quadrats with walia pellets lacked livestock droppings). A predictive spatial model identified key factors influencing ibex habitat use: herb cover, shrub cover, distance to cliff, road proximity, and altitude. Notably, walia ibex populations have shifted toward steeper eastern areas, likely due to increased human activity in lowland regions. This research underscores the challenges of balancing conservation efforts for endangered species with growing human encroachment.
