Inferring Interspecific Interactions Among African Savannah Herbivores Using Detectability‐Corrected Co‐Abundance Patterns

African Journal of Ecology, Volume 64, Issue 5, July 2026.
ABSTRACT Competition and facilitation are fundamental concepts in ecology, but evidence for the strength and direction of interspecific interactions within trophic levels is difficult to obtain, particularly in large assemblages of free‐ranging animals.

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

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
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 ...

Land Subsidence Susceptibility Mapping in Semi‐Arid Regions Using PS‐InSAR and Tree‐Based Ensemble Machine Learning: A Case Study From Çumra, Türkiye

Transactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT Land subsidence is an increasing environmental hazard in semi‐arid agricultural basins where intensive groundwater abstraction, compressible geological units, and expanding land‐use pressures interact. This study presents a PS‐InSAR and machine‐learning‐based framework for land subsidence susceptibility mapping in the Çumra District of the ...

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

River, Volume 5, Issue 2, Page 222-249, May 2026.
Abstract Soil erosion is a major global environmental and socio‐economic challenge, with impacts particularly severe in tropical, monsoon‐dominated mountainous regions, where heavy rainfall, steep terrain, and unsustainable land‐use practices accelerate land degradation.

Nine‐Year L‐Band InSAR Time Series of Tectonic and Non‐Tectonic Surface Deformation in Northern California

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study evaluates the performance of ALOS‐2 ScanSAR time series for resolving tectonic, volcanic, hydrologic, and geomorphic deformation across Northern California. Beginning in 2021, ALOS‐2 acquired ScanSAR data with a 14‐day repeat interval over the region, providing the closest available analog to the recently launched NISAR mission. The
