Neuroibromatosis tipo l: relación genotipo-fenotipo
Acta Neurológica Colombiana, 2020 INTRODUCCIÓN: La neurofibromatosis (enfermedad de von Recklinghausen) es una enfermedad autosómica dominante que presenta principalmente manifestaciones cutáneas y neurológicas. El objetivo es describir actualmente si existe o no relación entre las mutaciones encontradas en los pacientes con neurofibromatosis tipo 1 y las características clínicas

New Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Journal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA
Wildlife Monographs, Volume 222, Issue 1, June 2026.We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

Adaptación de diez cultivares de Lolium sp. en el trópico alto de Nariño, Colombia
Agronomía Mesoamericana, 2019 Introducción. Los sistemas de producción de leche en el departamento de Nariño, Colombia, se caracterizan por la predominancia del pasto kikuyo (Cenchrus clandestinus), el cual presenta susceptibilidad a heladas, plagas y patógenos, lo que reduce su ...

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’
Functional Ecology, Volume 40, Issue 3, Page 560-562, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract In this reply, we clarify several conceptual misunderstandings raised in response to our Perspective on quantifying phenotypic plasticity. We emphasize that our central argument concerns the rigorous estimation of the magnitude of plasticity, rather than its mere ...
