The importance of long-term capture-mark-recapture archives for wildlife monitoring and research: Two examples from bat populations
Long-term capture-mark-recapture (CMR) projects provide useful data to study and monitor wildlife. Specifically, CMR data can help identify how an animal interacts with its environment and how these interactions change throughout its life. In this thesis, I use data and sample archives from temperat...
