New publication on using hypervolumes for niche modelling

Understanding where species occur is a major challenge in biogeography, and of applied interest for forecasting species responses to climate change. How to best make these species distribution models has been a central discussion in recent decades. The idea underlying many models is Hutchinson’s n-dimensional hypervolume concept, but many models now in use do not…

Setting up an aspen observatory network

We are using this summer in the Rocky Mountains to intensively examine how quaking aspen (Populus tremuloides) performs across different contexts. This response might be mediated by turnover in genotypes, because the species grows in potentially large clones with no genetic variation among stems. This response might also be mediated by variation in microclimate within…
