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

open access: yesWildlife 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

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

open access: yesWildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Radiographic Screening of Wild and Semi‐Wild Cape Ground Squirrels (Geosciurus inauris) for the Presence of Peri‐Apical Masses Associated With Elodont Incisor Teeth

open access: yesZoo Biology, EarlyView.
Peri‐apical masses were absent in both wild and semi‐wild Cape ground squirrels, despite dietary differences and minor incisor trauma. These findings suggest such lesions are rare outside captivity and not induced by low‐fiber diets alone, adding to the literature on environmental and dietary risk factors in elodont tooth pathology.

Alternative seed trait strategies are linked to a trade‐off between spatial and temporal dispersal

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal allows plants to seek favourable conditions or spread the risk of unfavourable conditions through space and time. While theory predicts a trade‐off between spatial and temporal dispersal, empirical tests have been stymied by the difficulty of measuring ...

Targeted behavioural and microclimate data collection substantially improves biophysical model predictions of energy expenditure in wild birds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Energy is fundamental for life and accurately predicting animals' energy expenditure under changing environments is central to ecology and global change biology. Energy expenditure in free‐living animals can be directly quantified using the doubly labelled water (DLW ...

Boldness and niche width structure spatial interactions in a natural rodent community

open access: yesJournal of Animal Ecology, EarlyView.
We show that individual behavioural differences (boldness) structure spatial encounter patterns within a natural multi‐species community. By linking personality to space use and interaction structure, our study demonstrates how intraspecific variation can scale up to shape community‐level processes.

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

open access: yesJournal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Fragmented and Dealigned: The 2024 British General Election and the Rise of Place‐Based Politics

open access: yesThe Political Quarterly, Volume 96, Issue 1, Page 13-25, January/March 2025.
Abstract While the outcome of the 2024 British general election signalled a resounding repudiation of the incumbent government—returning a 231‐seat swing from the Conservatives to Labour—it did not radically overturn the geography of electoral outcomes in England and Wales.
