Lower survival probabilities for adult Florida manatees in years with intense coastal storms
The endangered Florida manatee (Trichechus manatus latirostris) inhabits the subtropical waters of the southeastern United States, where hurricanes are a regular occurrence. Using mark-resighting statistical models, we analyzed 19 years of photo-identification data and detected significant annual variation in adult survival for a subpopulation in northwest Florida where human impact is low. That v

Florida manatees: Perspectives on populations, pain, and protection
This overview has three related objectives. First, it provides simple documentation, descriptive summaries, and anecdotal accounts that demonstrate the extent to which maiming, and likely pain and suffering, occur in wild manatees as a result of strikes by boats. The chapter calls attention to the issues wounding raises for policy makers and managers involved with implementing boat speed zones, pa

Parasites and commensals of the West Indian manatee from Puerto Rico
Metazoan parasites and commensals were collected from dead manatees salvaged in Puerto Rico. Thirty-five manatees were examined between 1980 and 1998. Parasites and commensals were identified in 20 (57%) manatees and included 3 species of helminths, 1 nematode (Heterocheilus tunicatus) and 2 digeneans (Chiorchis fabaceus and Cochleotrema cochleotrema). Two species of commensals were also associate

Estimates of annual survival probabilities for adult Florida manatees (Trichechus manatus latirostris)
The population dynamics of large, long-lived mammals are particularly sensitive to changes in adult survival. Understanding factors affecting survival patterns is therefore critical for developing and testing theories of population dynamics and for developing management strategies aimed at preventing declines or extinction in such taxa. Few studies have used modern analytical approaches for analyz

The impact of debris on the Florida manatee
The endangered Florida manatee ingests debris while feeding. From 1978 through 1986, 439 salvaged manatees were examined. Debris was in the gastrointestinal tract of 63 (14.4%) and four died as a direct result of debris ingestion. Monofilament fishing line was the most common debris found (N=49).
