Pixelated pathologies: Camera trapping as a tool for monitoring wildlife health

Journal of Applied Ecology, Volume 62, Issue 11, Page 2894-2913, November 2025.
Given the increasing emergence of diseases, some with conservation and public health implications, improving and expanding wildlife health surveillance strategies is imperative. Camera trapping is particularly relevant for detecting new outbreaks, monitoring high‐risk zones and evaluating risk mitigation measures. Abstract Camera trapping has become an

Marcadores moleculares para qualidade de ovocitos bovino

SPERMOVA, 2017
Oocyte selection using morphological criteria is currently used, but this selection approach has limitations in terms of accuracy, objectivity, and constancy. Therefore, the development of new methods that could allow the identification of molecular markers that can predict the oocyte competency more accurately is needed.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

A genome‐wide association study for recurrent laryngeal neuropathy in the Thoroughbred horse identifies a candidate gene that regulates myelin structure

Equine Veterinary Journal, Volume 57, Issue 4, Page 943-952, July 2025.
Abstract Background Equine recurrent laryngeal neuropathy (RLN) is an economically important upper respiratory tract (URT) disease with a genetic contribution to risk, but genetic variants independent of height have not been identified for Thoroughbreds.

Identification of Brucella canis Group 2 in colombian kennels Identificación de Brucella canis Grupo 2 en criaderos de perros en Colombia Identificação de Brucella canis Grupo 2 em criadouros de cães na Colômbia

Revista Colombiana de Ciencias Pecuarias, 2012
Background: recently, isolates of Brucella canis (B. canis ) were classified into two groups, Group 1 and Group 2, based on a 794 bp deletion in the polysaccharide deacetylase gene in Group 1, or absence of this deletion in Group 2. In Colombia, B. canis

Phylogenomic approach to integrative taxonomy resolves a century‐old taxonomic puzzle and the evolutionary history of the Acromyrmex octospinosus species complex

Systematic Entomology, Volume 50, Issue 3, Page 469-494, July 2025.
A comprehensive, integrative study approach combining morphology, population genetics, phylogenetics and biogeography revealed that the Acromyrmex octospinosus species complex consists of two species: A. octospinosus and its social parasite A. insinuator.
