Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Soil erosion responses to climate change in a tropical monsoon‐dominated river basin ‐ A geospatial perspective

River, EarlyView.
Climate change is projected to intensify soil erosion in the Chalakkudy River Basin, with bare lands and steep uplands emerging as the most vulnerable hotspots under high‐emission scenarios. Forested areas showed greater resistance to soil erosion, highlighting the importance of targeted soil conservation for sustainable watershed management in ...

Long-term vegetation changes in elephant-related areas of concern in Kruger National Park, South Africa. [PDF]

Ecol Appl
Abstract African elephants, whether alone or in combination with other environmental factors such as floods, droughts, fire, and other herbivores, have significant impacts on large savanna trees, often contributing to declines over time. However, their effects on woody vegetation in general remain less well understood.

Limited elephant impacts on baobabs despite increasing elephant densities in a newly established protected area

Conservation Science and Practice, EarlyView.
Researchers combined aerial and ground surveys to map baobab distribution and assess elephant herbivory impacts on baobabs across Karingani Game Reserve, Mozambique. Researchers found that aerial surveys were an effective tool for mapping baobabs and that baobabs were more likely to occur closer to permanent water, at lower elevations, and in areas ...

Assessing forest fragmentation and biodiversity impacts in sub‐Saharan Africa: Methodological challenges and conservation strategies for small‐scale agricultural landscapes

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,
