Retreat of large carnivores across the giant panda distribution range

, 2020
As both a flagship and umbrella species, the giant panda (Ailuropoda melanoleuca) is one of the most heavily invested species in conservation. Here, we report the wide distribution range retreat of the leopard (Panthera pardus, 81% loss), snow leopard (P.

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

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 ...

Forty years of captive breeding in Przewalski's horse: pedigree‐based insights into population growth, sex ratio, and inbreeding

Wildlife Biology, EarlyView.
Long‐term captive breeding programs play a critical role in the conservation and reintroduction of endangered species, yet they face persistent challenges related to demographic structure and genetic management. The Przewalski's horse Equus przewalskii, once extinct in the wild, represents a global model for conservation breeding supported by pedigree ...

Giant panda protection: challenges and hopes [PDF]

Environmental Science and Pollution Research, 2019
In this paper, we discussed some major issues that hinder giant panda protection, such as diverse and mixed threats, habitat fragmentation, as well as the survey method to be improved, and some new protection actions appeared, such as the pilot program for the giant panda national park system and the administration of the giant panda national park was ...

Climatic–Anthropogenic Synergy Drives Escalating Minimum Area Requirements and Connectivity‐Protection Mismatch in a Karst‐Endemic Primate

Integrative Zoology, EarlyView.
Climate change and anthropogenic activities drive antagonistic degradation of landscape connectivity for endangered François’ langur (1987–2024), causing 48.8% habitat loss, north‐south fragmentation, and centroid migration (1.2 km/yr). Despite protected areas buffering connectivity, static management fails dynamic priority habitats; we propose ...

Effects of Social Group Housing on the Behavioral and Physiological Responses of Captive Sub-Adult Giant Pandas

Animals
Wild giant pandas are inherently solitary creatures, however, the ex-situ conservation efforts significantly alter the living circumstances of their captive counterparts.

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Comparative Study of Nutrient Composition in 31 Species of Staple Food Bamboos Consumed by Giant Panda in China

Journal of Food Quality
The objective of this study was to examine the macronutrient content in the shoots, leaves, and culms of bamboo species across various seasons within the habitats of wild giant pandas and in the cultivated regions for captive giant pandas. Results showed
