Factors influencing indices of manatee abundance in the Fort Myers region, winter 1983/84.
Manatee Population Research Rept. (Gainesville, Fla., Florida Cooperative Fish & Wildlife Research Unit) No. 5: 1-63. 12 tabs. 12 figs.
–See also Appendix 1. Analyzes the effects of manatee density, visibility, temperature, tide, and survey techniques on aerial survey results. Concludes that the aerial survey data are not sufficient to estimate actual abundance and should instead be treated as indices of trends. Separate surveys should be designed to maximize precision and accuracy of data obtained. The "block/recount" survey technique is introduced to estimate the error associated with indices obtained from individual surveys, and calibration of observers is recommended.
