Complete tag loss in capture-recapture studies affects abundance estimates: an elephant seal case study ...
1. In capture-recapture studies, recycled individuals occur when individuals lose all of their tags and are recaptured as though they were new individuals. Typically, the effect of these recycled individuals is assumed negligible. 2. Through a simulation-based study of double tagging experiments, we...
