I developed a new modeling approach to differentiate temporary emigration from real absence of animals (death or permanent emigration) in mark-recapture data. I then helped colleagues, who study a population of white sharks (Carcharodon carcharias) in central California, to apply this method to their data to investigate migratory behavior’s differences between males and females. To apply the method, we were took advantage of the fact that, on the field, sharks can be detected by two different means: photo‐identification (dorsal fin) and acoustic transmitter tags.
This work was done in collaboration with the Hopkins Marine Station of Stanford University (USA) and Monterey Bay Aquarium (USA).
