Increasing numbers of killer whale individuals use fisheries as feeding opportunities within subantarctic populations
Jolly-Seber capture-mark-recapture models to estimate Crozet regular and type-D Killer whales populations. All codes are available for the simulation, the real data and the trends analysis (1) Simulation code (codesimul.R) is running alone. (2) Real data code (code_vraidata_revfin.R) makes use of th...
