Advances in methods for estimating stopover duration for migratory species using capture-recapture data.

摘要: Many species are migratory, resulting in a life cycle divided into periodic stages occurring different habitats occupied for limited amount of time. Estimating the time spent each habitat is crucial to understanding how individuals modulate their activities and thus evolutionary ecology conservation biology. Several methods, including some recent promising advances, can be used estimate stopover duration as well arrival departure probabilities at sites where monitored using capture-recapture sampling. Our objectives this study were (1) describe available models duration, (2) illustrate with an original data set what kinds questions addressed most (3) provide detailed appendix practical guide implementing these methods E-SURGE software. To potential testing biological hypotheses, we on marbled newts (Triturus marmoratus). We time-dependent time-elapsed-since-arrival effects (using both Markovian semi-Markov processes latter) model probability arriving departing from breeding pond compared relative performance models. findings showed strong sex effect duration: females stayed average 5.63 weeks whereas males only 3.03 weeks. In sexes, retention was mainly influenced by already there. Consequently, same similar pond, although they did not arrive simultaneously but successively. The selected demonstrated flexibility relevance applications conservation.
