Arnason, A. N., & Mills, K. H. (1987). Detection of handling mortality and its effects on Jolly-Seber estimates for mark-recapture experiments (Vol. 44).
Zusammenfassung: Handling mortality occurs in mark-recapture experiments if animals handled and released in a given sample have a higher mortality rate than animals that were alive but not sampled. This violates the assumption of equal survival required for forming the Jolly-Seber estimates of population abundance, survival, and recruitment. The authors show that handling mortality can produce very large biases in these estimates, and we develop a test to detect it. They investigate the power of this test and find that quite large biases can be produced at handling mortality rates that are too low to be detected. They also recommend methods to prevent handling mortality from occurring in fish sampling experiments and methods to reduce bias in the estimates. The test and the bias corrections are applied to mark-recapture data for a lake whitefish (Coregonus clupeaformis ) population and to data from simulated mark-recapture experiment.
