title: Data from: Spatial and seasonal variation in thermal sensitivity within North American bird species

description: Responses of wildlife to climate change are typically quantified at the
 species level, but physiological evidence suggests significant
 intraspecific variation in thermal sensitivity given adaptation to local
 environments and plasticity required to adjust to seasonal environments.
 Spatial and temporal variation in thermal responses may carry important
 implications for climate change vulnerability; for instance, sensitivity
 to extreme weather may increase in specific regions or seasons. Here, we
 leverage high-resolution observational data from eBird to understand
 regional and seasonal variation in thermal sensitivity for 20 bird
 species. Across their ranges, most birds demonstrated regional and
 seasonal variation in both thermal peak and range, or the temperature and
 range of temperatures of greatest occurrence. Some birds demonstrated
 constant thermal peaks or ranges  across their geographic
 distributions and while others varied according to local and current
 environmental conditions. Across species, birds typically invested in
 either geographic or seasonal adaptation to climate. Local adaptation and
 phenotypic plasticity are likely important but neglected aspects of
 organismal responses to climate change.

 Code sheets 1: models_sdm.R Species distribution modeling workflow using
 spatiotemporal exploratory models, allowing predictions to vary over space
 and time. 2: patching_outputs.R After workflow runs for all species
 (models_stem sheet), use this to compile relevant climate data and fit
 models to get metrics of variation in sensitivity to thermal conditions at
 the species level. 3: thermtol_cross_sp.R Linear models and figure
 generation to describe patterns across all species in our dataset. 4:

 weather on human observers. Dependencies all found in /source/ directory
