LANDSCAPE PHENOMICS: PREDICTING VULNERABILITY TO CLIMATE CHANGE BY LINKING ENVIRONMENTAL HETEROGENEITY TO GENETIC AND PHENOTYPIC VARIATION IN MTN STREAM FROGS
Our goal is to uncover spatial patterns of vulnerability to climate change using an integrative framework that links environmental heterogeneity to genetic and phenotypic variation in resilience traits, an approach we term “landscape phenomics”. Our fundamental premise is that environmental variation ultimately generates phenotypic variation through plasticity and evolution, and this phenotypic variation mediates the vulnerability of populations to environmental change. We are currently applying this framework to understand spatial variation in thermal tolerance and vulnerability to climate change in coastal and Rocky Mountain tailed frogs (Ascaphus truei and A. montanus) by integrating environmental (temperature and food resources), genomic (SNP and whole genome resequencing), and physiological data. Preliminary genomic results indicate that populations are adapted to their local temperature regime. Moreover, thermal tolerance varies as a function of local temperatures and can change plastically to some degree in acclimation experiments. These early results suggest that both evolution and plasticity cause variation in this key resilience trait. Our ultimate goal will be to infer how this phenotypic variation influences spatial patterns of vulnerability in the face of climate change.
