Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Scouts vs. usurpers: alternative foraging strategies facilitate coexistence between neotropical Cathartid vultures

open access: yesIbis, Volume 166, Issue 4, Page 1368-1383, October 2024.
Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...

Longitudinal evaluation of the cutaneous and rectal microbiota of German shepherd dogs with perianal fistulas undergoing therapy with ciclosporin and ketoconazole

open access: yesVeterinary Dermatology, Volume 35, Issue 4, Page 375-385, August 2024.
Background – Perianal fistulas are painful ulcers or sinus tracts that disproportionately affect German shepherd dogs and are proposed as a spontaneous animal model of fistulising Crohn's disease. Objectives – To characterise the rectal and cutaneous microbiota in German shepherd dogs with perianal fistulas and to investigate longitudinal shifts with ...

Changes in thermal niche position and breadth of bird assemblages in Spain in relation to increasing temperatures

open access: yesJournal of Biogeography, Volume 51, Issue 5, Page 783-796, May 2024.
Abstract Aim Animal communities around the world are responding to climate change by altering their taxonomic composition, mainly through an increase in the colonisation rate of warm‐dwelling species and the local extinction of cold‐dwelling ones. We assessed whether the taxonomic composition of bird assemblages in peninsular Spain has changed in ...
