Genomic Prediction and Genome‐Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 342-353, March 2026.
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 365-374, March 2026.
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Jaguar Density at the Northeastern Limit of Its Distribution in Mexico

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study presents the first estimate of jaguar density in northeastern Mexico using a spatial capture–recapture model with random thinning, which incorporates both identified and unidentified camera trap detections. Conducted over 91 days with 104 cameras, the model yielded a density of 1.29 individuals per 100 km2 in the El Cielo–Sierra de Tamalave ...

Biopolitica y zootecnia

Historia y Sociedad, 2012
En este trabajo se pretende estudiar, a partir del siglo XVII, en qué la constitución de la especie y de los hombres como ''seres vivos'' en objetos de gobierno –lo que Michel Foucault califica de ''biopoder''– establece la posibilidad de transferencia de técnicas y de problemas que conciernen al gobierno de los otros seres vivos –en particular los ...
