Anthropogenic Infrastructures Shape Brown Bear Movements in Human‐Modified Landscapes

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Human activities are major drivers of changes in animal behaviour, resulting in diverse spatial and temporal activity patterns across species. In this study, we analysed telemetry data from brown bears in Finland, Slovakia and Romania, to compare how human infrastructure influences their movement behaviour.

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, Volume 5, Issue 1, Page 24-34, March 2026.
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.
