Genetic diversity in caribou linked to past and future climate change
Climate-driven range fluctuations during the Pleistocene have continuously reshaped species
distribution leading to populations of contrasting genetic diversity. Contemporary climate …

Evolutionary and demographic history of the Californian scrub white oak species complex: an integrative approach
Understanding the factors promoting species formation is a major task in evolutionary
research. Here, we employ an integrative approach to study the evolutionary history of the …

Climatically stable landscapes predict patterns of genetic structure and admixture in the Californian canyon live oak
Aim We studied which factors shape contemporary patterns of genetic structure, diversity
and admixture in the canyon live oak (Quercus chrysolepis). Specifically, we tested two …

Geographical isolation versus dispersal: Relictual alpine grasshoppers support a model of interglacial diversification with limited hybridization
J Ortego, LL Knowles - Molecular Ecology, 2022 - Wiley Online Library
Alpine biotas are paradigmatic of the countervailing roles of geographical isolation and
dispersal during diversification. In temperate regions, repeated distributional shifts driven by …

Temporal variation of heterozygosity‐based assortative mating and related benefits in a lesser kestrel population
Heterozygosity as a target of mate choice has received much attention in recent years and
there is growing evidence supporting its role in the evolution of mate preferences. In this study …

Genetic Consequences of Habitat Fragmentation in Long-Lived Tree Species: The Case of the Mediterranean Holm Oak (Quercus ilex, L.)
Large-scale forest fragmentation can increase interpopulation genetic differentiation and erode
the genetic variability of remnant plant populations. In this study, we analyze the extent of …
