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…

The solstice has just come, but summer still seems far away in parts of the Rocky Mountains. Many of the high peaks are still covered in snow. New growth and new leaves await bare ground and warm conditions. But why? Deciding when to deploy a leaf is a risky decision for a plant – too…

We are setting up a new forest dynamics plot in the Rocky Mountains this week, focused on understanding interactions and climate change responses among clones of quaking aspen (Populus tremuloides). The site will ultimately join the Global Ecosystems Monitoring network and contribute unique data from a low-diversity temperate forest in the coming years. Choosing a…

Recently the Ecological Society of America asked its members to write to their congressional representatives about federal science funding. Here are some excerpts from the letter I just sent to Arizona’s two senators, Jeff Flake and John McCain: I am writing to you about the FY18 appropriations bill, requesting that you take steps to restore…
