Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

Inferring Brown Bear Hair Snare Interactions by Automatically Detecting Bipedalism on Camera Trap Images Using Pose Estimation and a Multilayer Perceptron

Remote Sensing in Ecology and Conservation, EarlyView.
This study proposes an automated method to infer brown bear hair snare interactions by detecting bipedal behavior in camera‐trap images using a pose estimation model and a multilayer perceptron (MLP). A YOLO‐based model, fine‐tuned from humans and dogs to a custom dataset, achieved high performance (≈93% keypoint precision and ≈96% classification ...

From field to lab, facilitating non‐invasive genetic survey. Lessons from an arctic bird living at the edge, the rock ptarmigan in the French Alps

Wildlife Biology, EarlyView.
The rock ptarmigan Lagopus muta is an elusive species whose monitoring is hindered by its cryptic behavior and the difficulty in accessing its high‐elevation habitats. Although non‐invasive genetic sampling offers a promising alternative, its effectiveness can be constrained by DNA degradation and environmental conditions.
