Plasticity of cold tolerance and body composition in response to varying warming conditions in a temperate wolf spider

Here, we assessed plasticity in cold tolerance and body composition in the wolf spider S. stridulans exposed to three distinct simulated winter temperature regimes: one that reflects current conditions, one that reflects a warmer winter, and one that reflects a warmer winter with increased diurnal variation. We found that the critical thermal minimum (CTmin; the lowest temperature a spider can remain active) was plastic. Specifically, CTmin was lowest at the coldest time of the simulated winter, and it was lowest in spiders exposed to current winter conditions compared to spiders exposed to warmer simulated winters. In contrast, the supercooling point, or the temperature at which spiders spontaneously freeze, was invariant across time and winter conditions. Growth rates also depend on winter conditions, with spiders from warmer and more variable winters exhibiting significantly higher growth rates. Protein and lipid contents, however, were not affected by winter environment, indicating ..., , # Data from: Plasticity of cold tolerance and body composition in response to varying warming conditions in a temperate wolf spider

## Description of the data and file structure

Spiders were exposed to one of three simulated winter conditions, a current winter, a warmer winter, and a warmer and more variable winter. At various time points, spiders were sampled from these environments, and we assessed their critical thermal minimum, supercooling points, body size, and energy store content (lipids, carbohydrates, and proteins).
