摘要

Site fidelity and movement decisions in territorial species are often shaped by reproductive success and social context. These factors likely influence the motivation of an individual to return to a site where they have had previous mating success. We tested if reproductive behavior shapes movement decisions in the glassfrog Hyalinobatrachium valerioi, a species where males exhibit parental care by guarding clutches at oviposition sites until just before hatching. We hypothesized that recent mating success (i.e. presence of a clutch) would impact homing behavior. We expected males with clutches present at their site to home more reliably and faster, as they are likely more motivated to return to or remain at sites where they recently had mating success and/or should resume caring duties. Males with clutches homed more often, while males without clutches often remained in novel environments, supporting the reproductive performance hypothesis. Homing duration was affected by translocation distance and the presence of other males at release sites, with quicker returns observed under socially competitive conditions. These findings suggest that reproductive investments and social settings can shape movement decisions in H. valerioi, shedding light on the behavioral mechanisms underlying homing behavior in amphibians.
