Health Effects and Behavioral Response of Florida Manatees (Trichechus manatus latirostris) to Persistent Algal Bloom and Associated Loss of Seagrass Resources in Brevard County, Florida
USGS researchers are working with partners to assess the health and foraging behavior of Florida manatees in the northern Indian River Lagoon and Banana River, areas that have experienced declining seagrasses due to an extended phytoplankton bloom.
Loggerhead Iridium Locations in Northwest Florida 2019-2021
This dataset is comprised of times, locations, and water temperatures collected from iridium satellite tags attached to 11 loggerhead sea turtles between 2019 and 2021.
GPS telemetry of Florida manatees and riverine water temperatures from southwest Florida 2002-2015
These data represent 1) GPS telemetry of 40 Florida manatees from 2002 through 2008, covering southwest Florida from Charlotte Harbor to Florida Bay, and 2) water temperature readings from 10 riverine sites in the Everglades region of southwest Florida using Onset dataloggers from 2008 through 2015.
GPS Telemetry and other data sets of Florida manatees from Crystal River, FL 2006-2018
These data represent
1) Telemetry from Florida manatee from Crystal River, FL 2006-2018
2) Observations of manatees, swimmers and paddlecraft from Three Sisters Springs, Crystal River, FL 2014-2017
3) GIS polygons of aquatic landscape features from Crystal River, FL.
Manatee tracking, sighting and environmental data from the Northern Gulf of Mexico, 2013-2019
Data sets collected for manatee movement and habitat research in the Northern Gulf of Mexico from 2013-2019. These include manatee GPS tracking, manatee sightings, aquatic vegetation from manatee use areas, and environmental data (salinity and bathymetry at vegetation sampling sites).
Morphological measurements of Antillean manatees from Guantanamo Bay, Cuba
The data were collected by U.S.G.S. biologists and their partners during several field trips from March 2013 to April 2014 in Guantanamo Bay, Cuba. Data were collected during the manatee health assessments. The U.S. Geological Survey's Sirenia Project is a federal research effort focusing on manatee biology and ecology with a long history of studies in the U.S., Puerto Rico, and the international

Deep vs shallow: GPS tags reveal a dichotomy in movement patterns of loggerhead turtles foraging in a coastal bay
BackgroundIndividual variation in movement strategies of foraging loggerhead turtles have been documented on the scale of tens to hundreds of kilometers within single ocean basins. Use of different strategies among individuals may reflect variations in resources, predation pressure or competition. It is less common for individual turtles to use different foraging strategies on the scale of kilomet

Quality of thermal refuges influences use by the cold-intolerant Florida manatee
ABSTRACT: Thermal refuges are habitats used by species for behavioral thermoregulation. These habitats can be highly dynamic and are often influenced by fluctuations in local climate. When protected species require thermal refuges, it is necessary to identify stable and high-quality areas by evaluating species use in response to variation in thermal refuge quality. Here, we assessed behavioral the

How do ambient conditions and management actions affect manatee movements and habitat use?
Kings Bay in northwest Florida, USA, is an important winter home of the largest aggregation of Florida manatee (Trichechus manatus latirostris), and the only location in the United States where visitors legally swim and interact with manatees. In addition to ambient conditions, visitors to the area and management actions have the potential to influence manatee behaviors. We tracked 32 manatees wit

Analysis of body condition indices reveals different ecotypes of the Antillean manatee
Assessing the body condition of wild animals is necessary to monitor the health of the population and is critical to defining a framework for conservation actions. Body condition indices (BCIs) are a non-invasive and relatively simple means to assess the health of individual animals, useful for addressing a wide variety of ecological, behavioral, and management questions. The Antillean manatee (Tr

Traveling to thermal refuges during stressful temperatures leads to foraging constraints in a central-place forager
Central-place foragers can be constrained by the distance between habitats. When an organism relies on a central place for thermal refuge, the distance to food resources can potentially constrain foraging behavior. We investigated the effect of distance between thermal refuges and forage patches of the cold-intolerant marine mammal, the Florida manatee (Trichechus manatus latirostris), on foraging

Coastal habitat change and marine megafauna behavior: Florida manatees encountering reduced food provisions in a prominent winter refuge
A decline in submerged aquatic vegetation (SAV) within Florida’s spring-fed thermal refuges raises questions about how these systems support winter foraging of Florida manatees Trichechus manatus latirostris. We analyzed telemetry data for 12 manatees over 7 yr to assess their use of Kings Bay, a winter refuge with diminished SAV. After accounting for the effect of water temperature, we hypothesiz

Movements and habitat use locations of manatees within Kings Bay Florida during the Crystal River National Wildlife Refuge winter season (November 15–March 31)
Kings Bay, Florida, is one of the most important natural winter habitat locations for the federally threatened Trichechus manatus latirostris (Florida manatee). Crystal River National Wildlife Refuge was established in 1983 specifically to provide protection for manatees and their critical habitat.

Consortial brown tide − picocyanobacteria blooms in Guantánamo Bay, Cuba
A brown tide bloom of Aureoumbra lagunensis developed in Guantánamo Bay, Cuba during a period of drought in 2013 that followed heavy winds and rainfall from Hurricane Sandy in late October 2012. Based on satellite images and water turbidity measurements, the bloom appeared to initiate in January 2013. The causative species (A. lagunensis) was confirmed by microscopic observation, and pigment and g

Landscape complementation, or how landscapes that contain two or more non-substitutable and spatially separated resources facilitate resource use, is critical for many populations.

Manatees mapping seagrass (USA & Puerto Rico)
West Indian manatees (Trichechus manatus) are secretive creatures. While some of their behaviours at winter aggregation sites in Florida are readily visible to the casual observer, many of their habits and movements are difficult to observe. They rely on submerged vegetation for nutrition, and seagrasses are one of their most important food sources.
