Tadpole_Competition_Data.txt: This is tab-delimited data from tadpole competition experiments. Column descriptions below:

• Block = categorical A, B, C, or D corresponding to temporal block (date)
• Start = Start date of experiment
• End = End date of experiment
• Species = categorical F, M, or P corresponding to one of the three species of the focal individual
• Basin = categorical basin code corresponding to one of the 36 basins used in experiment
• Trt = categorical F, M, P, or C corresponding to competition treatment (C = low density / 60 individuals of focal species)
• Examples:
• Species = F, Trt = F → high density F treatment
• Species = F, Trt = P → F individual in P treatment
• Stage = response variable Gosner developmental stage (ranging from 25 to 46 or NA if the individual did not survive)
• Mass = response variable final weight (g) (NA if individual did not survive)
• Length = Body length (mm) (NA if individual did not survive)
• Survival = 1 if individual survived; 0 if individual did not survive until the end of the experiment.

Competition_Model_Code.txt: This file contains R code to perform the following:

• Analyze the tadpole competition data with the three models described in the main text of the manuscript
