Summary: A total of 94% of lemur species are threatened with extinction and 17 giant lemur species are already extinct. Dr. Patricia Wright initiated conservation programs in southern Madagascar in the 1990s to prevent the extinction of lemurs. These programs continued and expanded, leading to the establishment of Center ValBio (CVB) in 2003. CVB believes in a science-based, One Health approach to conservation and operates environmental education programs in primary schools near Ranomafana national park.

Summary: Ranging behavior is an important strategy for nonhuman primates to obtain critical resources, with differences in range use patterns and sex variations. Females have larger home ranges than males, and seasonal and climatic factors impact range use differently across sexes.

Summary: The dry lowland and mangrove forests of Kutai National Park in Indonesia have provided vital ecosystem services and carbon sinks, but are facing threats from illegal logging and wildfires. Researchers used Google Earth Engine to track the rates and influences of forest loss in the park since 1997. They found a 15% loss of forest cover since 2000, with half of this loss occurring during the El Nino-induced wildfires of 2015-2016. The study also identified omissions in the burned area dataset, particularly in smallholder farms within the park.

Summary: The study reveals that black-and-white ruffed lemurs primarily feed on fruits, but shift towards a folivorous diet during fruit-lean seasons. They also reduce activity time, increase resting time, and prefer higher canopy levels during this period for thermoregulation benefits.

Summary: Livestock depredations by large carnivores, such as leopards and tigers, are increasing in rural Nepal. Factors influencing livestock depredations include carnivore species, animal husbandry practices, season, and deterrent techniques. Wildlife attacks on livestock near human settlements are severe and affecting livelihoods, with leopards killing more livestock than tigers.

Summary: Deforestation of tropical forests leads to loss of aboveground biodiversity and changes in belowground biological activity; reforestation can partially restore soil microbiome properties. Study revealed that soil organic matter and microbial abundance decreased after converting natural forests into grasslands, but after 30 years of reforestation, bacterial and archaeal abundance were restored partially.

Summary: The reintroduction of wild dogs in Gorongosa National Park has been a success, with the founding packs showing high survival rates and successful reproduction. The study highlights the importance of pre-release preparation and natural pack formations in aiding the success of reintroductions. Various factors such as habitat avoidance, dietary partitioning, and management strategies have contributed to the successful reintroduction of wild dogs in the large, unfenced landscape of Mozambique.

Summary: The Margalla Hills in Pakistan-Himalayan foothills are at risk of deforestation and forest degradation. However, a quantitative evaluation shows that forest cover has increased from 1988 to 2020, while moderate degradation has also increased. The main drivers identified are timber and fuel wood collection.

Summary: In this study, industry-specific emission profiles of PM2.5-bound PAHs were established, and the sources were determined qualitatively and quantitatively using diagnostic ratio method and positive matrix factorization method. The results showed that heavy oil combustion, coal and natural gas combustion, vehicle emissions, steel industry emissions, and tar volatilization were the main sources of PM2.5-bound PAHs near the industrial park. The contribution of each source to potential health risk did not correspond to their mass contribution to ambient PAHs.

Summary: The latrine behavior of lemurs serves as a means of olfactory communication for energy efficient resource defense and social bonding. Latrines are typically located in the core of home ranges for social bonding, while resource defense may involve establishing olfactory landmarks at the periphery of the home range.

Summary: This study investigates the relationship between poverty and lemur hunting and consumption in Madagascar. The results show high levels of poverty and widespread lemur hunting and consumption, but no significant relationship between the two. Future research should explore other contributing factors and test the effectiveness of livestock interventions near Kirindy Mitea National Park.

Summary: Analyzing the land cover changes in the Mount Elgon region is crucial for conservation and sustainable land management. This study used satellite imagery and GIS to analyze the changes in the upper Manafwa watershed of Mount Elgon. The results showed both positive and negative changes in different types of land cover.

Summary: The natural vegetation of Burkina Faso has been significantly affected by human activities. Previous studies have focused on diachronic analysis using satellite imagery, but lack quantitative and qualitative information on the future of the vegetation. This study uses a model to predict the vegetation dynamics of Deux Bale National Park, revealing a decrease in savanna vegetation and an increase in anthropized areas and gallery forests. Urgent action is needed to preserve the potential of forest resources.

Summary: Ashe juniper and escarpment live oak are two common woody species on the Edwards Plateau in Texas, with different hydraulic strategies, yet both experienced similar mortality rates during an extreme drought. Research found that escarpment live oak was better at maintaining transpiration during dry periods compared to Ashe juniper, suggesting that greater cavitation resistance may not always translate to greater drought resistance in these two species.

Summary: Amazonian rivers act as partial barriers to species dispersal and influence the distribution limits of similar species. Through simulation experiments, it was found that even if two competitively-identical species frequently cross rivers, the low probability of rare invaders outcompeting resident populations can maintain their allopatry for hundreds of generations. This process provides a plausible mechanism for the maintenance of Amazonian biodiversity and explains the spatial distribution limits caused by large rivers in the region.

Summary: Urban watersheds play a critical role in supporting biodiversity and ecosystem services. A study in Central Texas revealed heterogeneity in biodiversity and ecosystem service levels across urban green spaces. The findings suggest that increasing tree diversity can provide carbon sequestration benefits, and green spaces with greater riparian forest cover can reduce particulate matter concentrations and lower temperatures.
