Data from: Testing an hypothesis of hybrid zone movement for toads in France

Isolde Van Riemsdijk, Roger K. Butlin, Ben Wielstra, Jan W. Arntzen & Isolde Riemsdijk
Hybrid zone movement may result in substantial unidirectional introgression of selectively neutral material from the local to the advancing species, leaving a genetic footprint. This genetic footprint is represented by a trail of asymmetric tails and displaced cline centres in the wake of the moving hybrid zone. A peak of admixture linkage disequilibrium is predicted to exist ahead of the centre of the moving hybrid zone. We test these predictions of the movement hypothesis in...

Data from: The interplay among intraspecific leaf trait variation, niche breadth and species abundance along light and soil nutrient gradients

Alex Fajardo & Andrew Siefert
It is assumed that widespread, generalist species have high phenotypic variation, but we know little about how intraspecific trait variation (ITV) relates to species abundance and niche breadth. In the temperate rainforest of southern Chile, we hypothesized that species with wide niche breadth would exhibit 1) high among-plot ITV, 2) a strong relationship between trait values and the environment, and 3) a close fit between traits and local environment trait optima. We measured leaf functional...
