Information about population size, average breeding sucess and regional connectivity is relevant for assessing population status, understanding evolutionary processes operating at local scales, and unraveling how life-history traits affect these processes. We address the study of relevant demographic parameters such as census and effective population sizes, polygamy rates and gene flow by combining genetic analyses and individual-based capture-mark-recapture data. In this talk I will show some estimates obtained during our 10-year monitoring program in an amphibian community in central Spain to prove that integrative demography represents a good opportunity for obtaining robust demographic inferences with wide applications for evolutionary and conservation research.
