CYP1A1, CYP2E1 Y RIESGO A CÁNCER GÁSTRICO EN UNA POBLACIÓN COLOMBIANA DE ALTA INCIDENCIA
El objetivo fue probar la hipótesis de que en casos y controles, de una población colombiana con alta incidencia de cáncer gástrico, muestran diferencias significativas entre las frecuencias de los polimorfismos genéticos CYP1A1-m2 y CYP2E1-c2; y a la ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’
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 ...

Peruvian frogs underwent a climate‐driven range expansion into deglaciating mountains, exposing themselves and their fungal pathogen Batrachochytrium dendrobatidis (Bd) to challenging new thermal environments. Bd has dispersed extensively in these new habitats, and elevation may mediate the apparent sublethal impacts of infection for frogs.

A Dominant Founder Lineage Has Possible Fitness Costs for the Endangered Mexican Grey Wolf
ABSTRACT The Mexican grey wolf (Canis lupus baileyi) is an endangered and genetically distinct subspecies of grey wolf adapted to the warm climates of the southwestern United States and Mexico. Following centuries of eradication efforts, Mexican grey wolves were protected under the Endangered Species Act in 1976, prompting an international ex situ ...

Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity
ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.
