Variación genética en cerdo doméstico (Sus scrofa domestica) de Córdoba-Colombia basada en marcadores microsatélites

open access: yesRevista Mexicana de Ciencias Pecuarias, 2015
Se evaluó mediante veinte microsatélites la variación genética de tres poblaciones de cerdos en Córd oba-Colombia. T odos los loci estudiados fueron polimórficos con una heterocigosidad observada que osciló en un rang o de 0.2 a

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1904-1924, September 2026.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Can taxonomic richness be used as a surrogate for phylogenetic distinctness indices for ranking areas for conservation?

open access: yesAnimal Biodiversity and Conservation, 2007
¿Puede utilizarse la riqueza taxonómica como un indicativo de diferenciación filogenética para evaluar áreas de conservación? Se han propuesto varios métodos para evaluar prioridades de conservación de áreas. En este trabajo se compara el funcionamiento

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 857-867, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...

Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

open access: yesNew Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Chromosomal Inversion Associated With Diet Differences in Common Quails Sharing Wintering Grounds

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
A large chromosomal inversion in common quails (Coturnix coturnix) is associated with phenotypic traits. In a wintering population in southern Spain, we found all three karyotypes coexisting but showing differences in migratory behavior and diet, as exemplified by the isotopic signature.

High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement

open access: yesPLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 834-846, July 2024.
The genetic variation of crop wild relatives will be key for our survival, as environmental change represents an increasing global threat for agriculture and food security. Cucurbita lundelliana and Cucurbita okeechobeensis subsp. martinezii are wild relatives of cultivated squashes and pumpkins that could be used for crop improvement.
