Use of replicate counts to improve indices of trends in manatee abundance.
Wildl. Soc. Bull. 14: 265-275. 3 tabs. 1 fig.
—Uses replicate counts from winter aerial surveys at Fort Myers, Florida, to calculate 3 indices of abundance. Concludes that the sight-resight index is more suitable for detecting year-to-year trends in abundance than the density and total-count indices, but that more development of the approach may be needed.
