Imperiled Species

Generally speaking, imperiled species are those animals and plants that are in decline and may be in danger of extinction. While some species are federally protected under the Endangered Species Act, many species are not due to the lack of knowledge regarding their status and the environmental factors that may threaten their future.

Modeling Past Variation in Florida Manatee Survival, Breeding, and Movements Rates to Establish Baselines for Aquatic Ecosystem and Restoration Research

Long-term monitoring data in the Manatee Individual Photo-identification System (MIPS), developed and coordinated by WARC-Sirenia Project in collaboration with Florida’s Fish and Wildlife Research Institute and Mote Marine Laboratory, are the basis for modeling manatee demography rates.

Structured Decision Making for Management of Warm-Water Habitat of Manatees

Manatees are tropical to subtropical in distribution and, with few exceptions, Florida is the northern limit of their natural winter range.  The availability of warm-water habitat during winter is critical for the future persistence of the population in Florida.
