Mark-Recapture Jolly-Seber Abundance Estimation with Classification Uncertainty

摘要: Wildlife managers and ecologists are often interested in estimating abundance of animals belonging to a certain fixed group (e.g. sex), but some cases membership cannot always be ascertained. Group assignment uncertainties can occur either through the inability assign because lack group-specific characteristics males females look alike), training volunteers), or errors assignment. Recently, methodological advances closed population capture-recapture models have allowed for inclusion classification parameter estimates. We build on this work by addressing identification uncertainty estimation (open models), providing general method dealing with multiple groups/states when true underlying group/state considered duration experiment. then apply methodology estimate sex-specific abundances walleyes (Stizostedion vitreum) Mille Lacs, Minnesota.
