Landscape features exist at multiple spatial and temporal scales, and these naturally affect
spatial genetic structure and our ability to make inferences about gene flow. This article …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

Rapid climate change jeopardizes tree populations by shifting current climate zones. To
avoid extinction, tree populations must tolerate, adapt, or migrate. Here we investigate …

Oak represents a valuable natural resource across Northern Hemisphere ecosystems,
attracting a large research community studying its genetics, ecology, conservation, and …

There is growing realization that intraspecific variation in seed dispersal can have important
ecological and evolutionary consequences. However, we do not have a good understanding …

Understanding how specific environmental factors shape gene flow while disentangling their
importance relative to the effects of geographical isolation is a major question in …

The use of diversity metrics has a long history in population ecology, while population
genetic work has been dominated by variance-derived metrics instead, a technical gap that …

A central question in evolutionary biology is how gene flow and natural selection shape
geographic patterns of genotypic and phenotypic variation. My overall research program has …

Neutral genetic markers have been employed in several ways to understand seed dispersal
patterns in natural and human modified landscapes. Genetic differentiation among spatially …

Habitat loss and fragmentation often reduce gene flow and genetic diversity in plants by
disrupting the movement of pollen and seed. However, direct comparisons of the …
