A complete mitochondrial genome sequence of Asian black bear Sichuan subspecies (Ursus thibetanus mupinensis)

International Journal of Biological Sciences, 2007
We obtained the complete mitochondrial genome of U.thibetanus mupinensis by DNA sequencing based on the PCR fragments of 18 primers we designed. The results indicate that the mtDNA is 16 868 bp in size, encodes 13 protein genes, 22 tRNA genes, and 2 rRNA

Portable X‐Ray Fluorescence in the Assessment of Zinc Along Grizzly Bear Hair

X-Ray Spectrometry, EarlyView.
ABSTRACT As a biomarker of past uptake of zinc, hair presents an interesting option since its growth can provide a stored record over time. This study investigates the distribution of zinc in hairs gathered from a series of grizzly bears (Ursus arctos horribilis).

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 ...

Mitigating Human–Large Carnivore Conflicts via Time‐Regulated Management of Free‐Ranging Livestock in the Sanjiangyuan Region, China

Integrative Zoology, EarlyView.
The graphical abstract illustrates the comprehensive workflow of our study, from the deployment of infrared cameras at sites with high activity of four large carnivores, through data collection and assessment of activity patterns, to the prediction of time periods with potential human–large carnivore conflicts and the proposal of corresponding ...

Food Subsidies Reduce Livestock Depredations by a Recovering Carnivore

Animal Conservation, EarlyView.
Diversionary feeding—providing food caches to divert predators away from preying on livestock—is a strategy to reduce depredations by Mexican gray wolves but has not been evaluated for its effectiveness. We used data from the Mexican wolf recovery program from 2014‐2021 to evaluate whether diversionary feeding reduced livestock depredations by wolf ...

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

Animal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

Acta Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Ecological plasticity of denning chronology by American black bears and brown bears

Global Ecology and Conservation, 2019
Ecological plasticity may index the capacity of individuals, populations, and species to respond to stochasticity. Few studies have demonstrated mechanisms influencing expression of plasticity and less have addressed proximate and causal mechanisms at ...
