Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

Wildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

Wildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Heightened threats to small woodland caribou populations in Canada and key considerations for their persistence Menaces pesant sur les petites populations de caribou des bois au Canada et considérations essentielles à leur rétablissement

Wildlife Monographs, EarlyView.
Abstract Woodland caribou (Rangifer tarandus) are one of the most iconic wildlife species in Canada. These large ungulates depend on undisturbed, interconnected assemblages of mature and old‐growth conifer forests for survival, and exhibit life‐history traits typical of K‐selected species (i.e., low reproductive rates, long generation times, and slow ...

Remotely enabling live traps for mesopredator capture: Potential benefits and use of time‐controlled trap access

Wildlife Society Bulletin, EarlyView.
A method is described for remotely controlling the interval of time available for live trap animal capture using a programmable door which controls animal access to a readied live trap within a housing structure. Based on management objectives or other considerations, utilities include the ability to eliminate repeat site visits in some contexts to set

Localized resources enable noninvasive genetic monitoring of small populations of mountain ungulates

Wildlife Society Bulletin, EarlyView.
Using microsatellite analysis of fecal samples collected at mineral licks from 2019–2022, we assessed abundance, apparent survival and genetics of bighorn sheep in the Teton Range, Wyoming, USA. Annual abundance estimates ranged from 118−132 individuals split into 2 similar‐sized demes and apparent survival estimates ranged from 0.72–0.92.

The ‘big houses‐big cars dilemma’: How do we reconcile the prevalence of positive correlations among life history traits?

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Life history theory assumes that there are negative correlations among different components of the life history—investing more in reproduction now means taking resources away from growth, maintenance or the ability to reproduce in the future.

Out of the fire and into the frying pan: Hostile post‐fire thermal conditions reduce activity windows for reptiles

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change and intensified fire regimes are reshaping ecosystems globally. Reptiles, as ectotherms, rely on microhabitat shelters to buffer against thermal extremes, yet the capacity of these shelters to persist or function following fire remains poorly understood ...
