More about Jess’ research:
Small mammals (voles and lemmings) are a key component of Arctic ecosystems. Their cyclic population fluctuations have cascading impacts on tundra food webs, impacting reproductive success in predators and alternate prey species alike, and influencing plant biomass and community composition. However, there remains much debate about the drivers of population cycles as well as the impacts of warming on these cycles.
My research will combine field studies in Northern Alaska with laboratory analysis of stress hormones in current and historical populations to increase our understanding of potential mechanisms driving Arctic rodent populations.
