Tubulopapillary Mammary Carcinoma in a Brown Bear (Ursus arctos) [PDF]

Journal of Wildlife Diseases, 2008
A 28-yr-old, nulliparous female brown bear (Ursus arctos) at the Karacabey Ovakurusu Bear Sanctuary presented with an enlargement of the mammary gland. Three other nodules were also noted in the proximity of the mammary gland and over the vulva. Clinical, hematologic, ultrasonographic, and radiologic examinations were performed; the enlarged mammary ...

Balancing forage and fear: How people, environment and predators shape reindeer grazing in the Fennoscandian tundra

People and Nature, EarlyView.
Abstract The long history of reindeer herding in Fennoscandia has shaped the mountain tundra by influencing its productivity, nutrient and carbon cycling and vegetation structure. By partly limiting shrub expansion, extensive reindeer grazing contributes to ecosystem resilience and helps mitigate climate change effects.

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 ...
