Trap‐dependence in capture–recapture studies: empirical evidence in vertebrates and biological meaning

open access: yesOikos, EarlyView.
Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical
