| 1991 | An evaluation of aerial survey replicate count methodology to determine trends in manatee abundance. Wildl. Soc. Bull. 19: 298-309. 2 tabs. 4 figs. –Analyzes winter survey data from Crystal and Homosassa rivers, Florida, 1985-86. Concludes that unit-recount surveys (Packard et al., 1986) should not be used to develop a population index based on resightings of individuals, but can serve to improve survey designs and to obtain an index with a measure of variation at specific aggregation sites. They could also be used in conjunction with a "variable effort recount" method, to standardize the latter and make the former method more flexible. | ||
