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

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.

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.

Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling

Molecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change

Ecology and Evolution, Volume 15, Issue 5, May 2025.
We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.

Tracing the origin of the alien pest Cydia pomonella in Algeria through a worldwide comparison of the species’ DNA barcodes Reserche de l'origine du ravageur exotique Cydia pomonella en Algérie grâce à une comparaison mondiale des codes‐barres ADN de l'espèce Rastreando el origen de la plaga exótica Cydia pomonella en Argelia mediante una comparación mundial de los códigos de barras del ADN de la especie

Agricultural and Forest Entomology, Volume 27, Issue 2, Page 171-181, May 2025.
Cydia pomonella (Lepidoptera: Tortricidae) is a harmful apple and pear pest spread worldwide. We sequenced, for the first time, mitochondrial DNA from C. pomonella caterpillars collected in Northern Africa (Algeria) and assessed where it was introduced from.
