Heavy Metal Contamination in Arenillas Ecological Reserve Soils: Correlation and Conservation Impact

Land Degradation &Development, Volume 36, Issue 10, Page 3454-3471, June 2025.
ABSTRACT This study addresses the critical knowledge gap regarding heavy metal contamination in the soils of the Arenillas Ecological Reserve (AERv), located on the southwest coast of Ecuador. Despite being a fragile and highly biodiverse ecosystem, little is known about the magnitude, spatial distribution, and drivers of heavy metal contamination in ...

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

Ecology 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

Veterinary 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.

Mapping nut‐cracking in a new population of wild capuchin monkeys (Sapajus libidinosus) at Ubajara National Park, Brazil

American Journal of Primatology, Volume 86, Issue 4, April 2024.
Capuchin monkeys (Sapajus libidinosus) at Ubajara National Park, Brazil, customarily use hammerstones to crack open at least two species of palm nuts, macaúba and babaçu. We systematically surveyed stone tool use sites in this park, recording and measuring stone tools, processed foods, and available lithic resources.

Conservation detection dogs: A critical review of efficacy and methodology

Ecology and Evolution, Volume 14, Issue 2, February 2024.
Conservation detection dogs (CDD) can be effective and applied to possibly limitless conservation scenarios but moving forward researchers must provide more consistent and detailed methodologies so that comparisons can be conducted, results are more easily replicated and progress can be made in standardising CDD work. This review aims to summarise what

Evaluating hybrid speciation and swamping in wild carnivores with a decision‐tree approach

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract Hybridization is an important evolutionary force with a principal role in the origin of new species, known as hybrid speciation. However, ongoing hybridization can create hybrid swamping, in which parental genomes are completely lost. This can become a biodiversity threat if it involves species that have adapted to certain environmental ...

Occurrence of Typical Domestic Animal Viruses in Wild Carnivorans: An Emerging Threat to the Conservation of Endangered Species

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Wild species are susceptible to several typical domestic animal pathogens, and the increasingly close contact between these groups is a predictive factor for disease exposure. Some viruses are important and old‐known, and others are emerging or reemerging for domestic carnivorans and have been identified as threats to the conservation of wild mammals ...
