Hybrid speciation and independent evolution in lineages of alpine butterflies.
The power of hybridization between species to generate variation and fuel adaptation is poorly understood despite long-standing interest. There is, however, increasing evidence that hybridization often generates biodiversity, including via hybrid speciation. We tested the hypothesis of hybrid speciation in butterflies occupying extreme, high-altitude habitats in four mountain ranges in western ...
متن کاملCardiovascular adaptation, functional capacity and Angiotensin-converting enzyme I/D polymorphism in elite athletes.
INTRODUCTION AND OBJECTIVES Angiotensin-converting enzyme (ACE) is associated with the development of cardiac hypertrophy and improved physical fitness. The objective of this study was to investigate the relationship between the ACE gene insertion/deletion (I/D) polymorphism and adaptation to sports training. METHODS The study included 299 elite Spanish athletes (193 men and 106 women) from 3...
متن کاملThe demographic impacts of shifts in climate means and extremes on alpine butterflies
1. Climate change impacts organismal performance via both shifts in mean conditions and acute thermal stress events. Yet, we know little about the relative fitness impacts of climate means and extremes, and how phenotypes mediate these effects. 2. Here, we incorporate demography in a biophysical model of two alpine butterflies with distinct phenotypes to examine the impacts of recent climate ch...
متن کاملGlacial survival and local adaptation in an alpine leaf beetle.
The challenge in defining conservation units so that they represent evolutionary entities has been to combine both genetic properties and ecological significance. Here we make use of the complexity of the European Alps, with their genetic landscape shaped by geographical barriers and postglacial colonization, to examine the correlation between ecological and genetic divergence. Montane species,...
