Extreme spatial confinement and high site fidelity in a crevice-dwelling lizard with a minimal home range

Our findings suggest that, in species with extreme habitat specialisation, home-range extent may be better explained by environmental stability and foraging strategy than by the classical body-size relationship. These results highlight the potential for tight microhabitat coupling to decouple spatial use from allometric expectations. Moreover, because microhabitat specialists are particularly vulnerable to habitat fragmentation and refuge loss, it is essential to consider spatial use patterns when assessing conservation status and designing management strategies.
