Manatees

WARC's Sirenia Project conducts long-term detailed studies on the life history, population dynamics, and ecological requirements of the West Indian manatee. Sirenia Project biologists work cooperatively with federal and state researchers and managers on research identified as essential for the recovery of the species.

Port of the Islands (POI) basin
August 1, 2016

Critical information predicting condition changes in manatee habitat resulting from the alteration of freshwater flows to estuaries is needed to develop the PSRP Detailed Design and PSRP Operations Plan components and complete consultation under the Endangered Species Act.

Validated modeling and sampling methodology
August 1, 2016

Turbid water conditions make the delineation and characterization of benthic habitats difficult by traditional in situ and remote sensing methods. Consequently, only a small fraction of this valuable resource has been mapped or characterized.

Florida Manatee with a tracking devise attached
June 16, 2016

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.

Florida manatee population uses warm-water discharges from power plants during winter
April 25, 2016

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.

Winter Manatee Foraging Behavior and the Decline of Seagrass Beds in the Northern Indian River Lagoon
April 17, 2016

With high numbers of manatees using the Florida Power and Light power plant warm water refuge during winter, their impact on the seagrass beds in the Indian River Lagoon is considered an important indicator of the long-term capacity of the area to support the manatees. USGS is working with partners to investigate the spatial extent and intensity of manatee use of seagrass beds in the area. 

West Indian manatees
April 8, 2016

Population models developed by USGS are the primary decision-support tools used for status assessments, and rely on estimates of adult survival and reproduction rates from mark-recapture studies.

Photo identification of manatees
April 5, 2016

USGS works with partners to assess manatee distribution and habitat use throughout the Northern Gulf of Mexico.

Research diver and manatees - WARC
February 26, 2016

Since 1978, USGS scientists have photo-documented manatees in the Southeast United States. Now, more than 3,000 manatees can be found in the MIPS database.

Manatee in natural habitat - WARC
February 26, 2016

A multi-agency effort assesses the health of manatees and provides baseline information on their health, reproductive status, and nutritional condition.
