Résumé
1.The environment of most species is heterogeneous at different spatial
and temporal scales; this heterogeneity can have a direct effect on
various components of fitness. As a consequence, individual space-use and
movement strategies are central issues in ecology and conservation and
receive considerable attention from researchers. 2.In the last 30 years,
this issue has led to the development of capture–recapture models that
allow movement between sites to be quantified, while handling imperfect
detection. For studies involving numerous recapture sites in which the
emphasis is on dispersal or migration rather than movement between
particular sites, Lagrange et al. recently proposed a parsimonious CR
multi-event model that contrasts individuals that move and individuals
that stay in place, irrespective of the sites involved. 3.In this study,
we developed a generalized version of this model to allow survival
probability and movement probability to differ for different types of
habitat to which the individual sites may be assigned. We investigated the
potential of this new parameterization by studying the movements of an
amphibian, the yellow-bellied toad (Bombina variegata), in a set of
breeding and resting/foraging ponds. 4.Our capture-recapture multi-event
model provides a highly flexible tool allowing users to model movements
within and between several habitats. This approach can be potentially used
to study movement behavior and space-use strategies of a wide range of
taxa.
