Comparative Trends of Sociality Among Terrestrial Carnivores: A Multivariate Analysis 陆生食肉动物社会性的比较趋势:一项多变量分析

Wildlife Letters, EarlyView.
In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

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).

Seasonal and individual variation in the use of rail-associated food attractants by grizzly bears (Ursus arctos) in a national park

PLoS ONE, 2017
Similar to vehicles on roadways, trains frequently kill wildlife via collisions along railways. Despite the prevalence of this mortality worldwide, little is known about the relative importance of wildlife attractants associated with railways, including ...

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 ...
