Namib Sand Sea
—
2020 —
WHE673915E44C
Research indicates that the aridification of the Namib Desert, one of UNESCO's World Heritage Sites, was primarily initiated or significantly intensified during the early Late Miocene period due to the strengthening of upwelling in the Benguela Current System. This finding is supported by sedimentological, paleontological, and geochemical analyses of oceanic cores from the Walvis Ridge Abutment, which span from the Middle Eocene to the Late Pleistocene. The study suggests that while weak, sporadic upwelling occurred earlier (from Middle or Late Oligocene to Middle Miocene), it was not sufficient to cause significant aridification. Instead, the marked intensification of cold, nutrient-rich water upwelling in the early Late Miocene led to the transformation of the Namib from wooded-grasslands to the arid desert it is today.

Ban Chiang, a prehistoric site in Northeast Thailand, challenges long-held beliefs about the origins of metallurgy in Southeast Asia. Research published in Volumes 2A (2018) and 2B (2019) of its comprehensive study suggests that bronze production emerged independently in this region as early as 7000 B.P., predating similar findings elsewhere. This conclusion stems from meticulous excavations conducted between 1974 and 1975, which uncovered artifacts alongside earlier thermoluminescence dating evidence. The study also highlights the cultural significance of Ban Chiang, where looting in the late 1960s threatened its integrity before systematic excavations were launched. By analyzing a sequence of prehistoric layers across multiple sites—including Ban Tong, Ban Phak Top, and Don Klang—the research provides a robust framework for understanding the social impact and technological advancements of early metallurgy in the region.

A comprehensive baseline for monitoring medium to large non-volant mammals in the Gran Sabana, Venezuela, reveals significant habitat associations and species richness comparable to lowland Guianas and Amazon sites. The study identified 29 mammal species, including endangered and vulnerable ones like Priodontes maximus and Panthera onca, using a stratified sampling design with camera traps across forest, shrub-intermediate, and savanna habitats. Notable findings include the first record of Myoprocta pratti in Canaima National Park and significant habitat preferences such as Cerdocyon thous for savanna (P < 0.01) and Leopardus pardalis for shrub-intermediate habitats (P < 0.05). The research also highlights ecological concerns due to the uncontrolled development of the Orinoco Mining Arc, which threatens biodiversity in this UNESCO World Heritage Site.
