experimental translocations: pitfalls and alternatives for quantifying animal movement in fragmented landscapes

摘要: As anthropogenic change continues to fragment terrestrial habitats, conservation biologists are increasingly concerned with how wild animals move through fragmented landscapes. Experimental translocations have recently gained popularity as a technique determine landscape permeability by in In experimental translocations, researchers capture individuals — usually adults and release them elsewhere order whether they able cross the return their original location. We argue that most two inherent confounding factors age of individual homing ability narrow spatiotemporal scale may give it limited address important management questions discuss three alternative techniques (telemetry, capture-mark-recapture, genetics), recommend only be undertaken if: 1) avoid factors; 2) validated other techniques; 3) no options available for obtaining data. stress do proceed must acknowledge using an indirect proxy quantify natural animal movement.
