Late summer plateau pika spatial habitat use revealed by high‐resolution wildlife tracking and unmanned aerial vehicle data on the Qinghai‐Tibet Plateau

Grassland Research, EarlyView.
Tiny “ecosystem engineers,” plateau pikas range across 1600 m², about two basketball courts, mixing soil and nutrients that sustain Tibet's fragile grasslands. Custom‐made trackers and drone imagery show dawn‐to‐dusk surface foraging and nested‐scale patch choices, offering fresh guidance for wildlife‐friendly grazing management.

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

River Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.
