Demographic data from two chorus frog populations in Colorado

We used 29 years of data on boreal chorus frogs at two sites to view life-history, estimate demographic parameters, assess weather-related covariates, and determine the magnitude of process variation in target parameters. Average estimates of survival probabilities were 0.51 (Standard error [SE]=0.04) and 0.43 (SE=0.04), and average estimates of recruitment probabilities were 0.64 (SE=0.07) and 0.44 (SE=0.04). Process variation accounted for greater than 76% of the total temporal variation in both parameters at one pond and in survival probability alone at the other.
