Journal ArticleDOI
Informed dispersal, heterogeneity in animal dispersal syndromes and the dynamics of spatially structured populations
TL;DR: Recent literature providing strong evidence that individual variation in dispersal has an important impact on both reinforcement and colonization success and therefore must be taken into account when predicting ecological responses to global warming and habitat fragmentation is discussed.
Journal ArticleDOI
Sex ratio bias, male aggression, and population collapse in lizards
TL;DR: Numerical projections show that an "evolutionary trap" toward extinction threatens populations in which there is a substantial mating cost for females, and environmental changes or management practices skew the ASR toward males.
Journal ArticleDOI
How does selection operate on whole-organism functional performance capacities? A review and synthesis
TL;DR: This review of existing literature on the nature and intensity of natural and sexual selection on whole-organism performance traits found no evidence that selection was stronger on performance traits than morphological traits.
Journal ArticleDOI
A comparative analysis of dispersal syndromes in terrestrial and semi-terrestrial animals.

TL;DR: Good dispersal ability was consistently associated with high fecundity and survival, and in aerial dispersers it was associated with early maturation, highlighting the complex role of dispersal in the evolution of species life-history strategies.
Journal ArticleDOI
Physical performance and Darwinian fitness in lizards.
Jean-François Le Galliard,Jean-François Le Galliard,Jean Clobert,Régis Ferrière,Régis Ferrière +4 more
TL;DR: This analysis of locomotor performance in the common lizard demonstrates that initial endurance is indeed highly heritable, but natural selection in favour of this trait can be unexpectedly weak, and a manipulation of dietary conditions unravels a proximate mechanism explaining this pattern.
