Data from: Genetic variation of loci potentially under selection confounds species-genetic diversity correlations in a fragmented habitat

Positive species-genetic diversity correlations (SGDCs) are often thought to result from the parallel influence of neutral processes on genetic and species diversity. Yet, confounding effects of non-neutral mechanisms have not been explored. Here, we investigate the impact of non-neutral genetic diversity on SGDCs in high Andean wetlands. We compare correlations between plant species diversity (SD) and genetic diversity (GD) calculated with and without loci potentially under selection (outlier loci). The study system includes 2188 specimens...

Data from: Woody climbers show greater population genetic differentiation than trees: insights into the link between ecological traits and diversification

The climbing habit is a key innovation in plants: climbing taxa have higher species richness than non-climbing sister groups. We evaluated the hypothesis that climbing plant species show greater among-population genetic differentiation than non-climber species. We compared the among-population genetic distance in woody climbers (8 species, 30 populations) and trees (7 species, 29 populations) coexisting in 9 communities in a temperate rainforest. We also compared within-population genetic diversity in co-occurring woody climbers and trees in...

Data from: Fruit size determines the role of three scatter-hoarding rodents as dispersers or seed predators of a fleshy-fruited Atacama Desert shrub

Andrea Loayza, Claudia Luna, Francisco Squeo, Claudia A. Luna, Andrea P. Loayza & Francisco A. Squeo
Scatter-hoarding rodents can act as both predators and dispersers for many large-seeded plants because they cache seeds for future use, but occasionally forget them in sites with high survival and establishment probabilities. The most important fruit or seed trait influencing rodent foraging behavior is seed size; rodents prefer large seeds because they have higher nutritional content, but this preference can be counterbalanced by the higher costs of handling larger seeds. We designed a cafeteria experiment...
