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
