Sample size estimates: a preliminary analysis of sample sizes required for mark-recovery and mark-resighting studies of manatees (Trichechus manatus) in Florida.
Manatee Population Research Rept. (Gainesville, Fla., Florida Cooperative Fish & Wildlife Research Unit) No. 4: 1-14. 4 tabs. 3 figs.
–See also Appendix 1. Concludes that estimation of annual survival rate by tag recovery from carcasses can yield only unacceptably imprecise results, but that mark-resighting methods may be successful, depending on rate of emigration and probability of sighting. Studies based on scar patterns would involve slightly different assumptions than those examined here.
