Seasonal evolution and its effects on competition

Rapid evolution can influence competitive dynamics. While theory and past work have focused on the competitive consequences of rapid evolution in response to competitors (e.g., character displacement), abiotic environmental factors are also responsible for much of the rapid evolution observed in nature. Yet, we lack knowledge of how evolution in response to a variable abiotic environment shapes competition between evolving species. Our knowledge of these effects is limited not only by the absence of direct quantification of environment-driven evolution’s effects on competition, but also by the rarity of systems in which environment-driven evolution itself has been measured across multiple competitors. Here, we used an outdoor mesocosm experiment with three species of naturally co-occurring Drosophilid fly competitors to quantify the seasonal evolution of stress tolerance and reproductive traits and the effects of this evolution on demographic performance under competition. We found that..., , , # Seasonal evolution and its effects on competition

Here, we present data and code for the paper: Seasonal evolution and its effects on competition. In this study, we maintained outdoor mesocosms of three species of drosophilid flies, tracked the evolution of these populations over the summer and fall, and conducted competition trials in the lab and field to quantify the effects of seasonal evolution on competition.

The repository contains datasets on phenotypic traits (body mass, fecundity, starvation tolerance, chill coma recovery, heat tolerance); competition trials; population dynamics in outdoor mesocosms; temperature data from ibuttons; and quantities derived from models using some of these data. The repository also contains code in R to analyze these datasets. Specifically, \"pheno_analyze_dryad.Rmd\" contains models analyzing phenotypic evolution; \"pheno_pca_dryad.Rmd\" analyzes this phenotypic evolution using principle components analysis; \"haldanes_dryad.Rmd\" computes rates of ...,
