Camouflage or Coincidence? Investigating the Effects of Spatial and Temporal Environmental Features on Feral Cat Morphology in Tasmania

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
Feral cats (Felis catus) have spread across Australia over the past 200 years, displaying various coat types, yet it remains unknown if any offers an adaptive advantage. Using a dataset of 24,657 camera‐trap images, we examined if any coat types correlate with spatial or temporal features.

Characterization of antimicrobial resistance profiles in Escherichia coli isolated from captive mammals in Ecuador

open access: yesVeterinary Medicine and Science, Volume 10, Issue 4, July 2024.
Among 90 E. coli isolates from 70 mammals, significant resistance was found to ampicillin (52.22%), ceftriaxone (42.22%) and cefuroxime (42.22%), with 27.78% being ESBL‐producing. Notably, 66.67% of isolates showed resistance to at least one antibiotic, and 35.56% exhibited multiresistant phenotypes.
