Deep vs shallow: GPS tags reveal a dichotomy in movement patterns of loggerhead turtles foraging in a coastal bay Deep vs shallow: GPS tags reveal a dichotomy in movement patterns of loggerhead turtles foraging in a coastal bay
Background Individual 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...

Quality of thermal refuges influences use by the cold-intolerant Florida manatee 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...

How do ambient conditions and management actions affect manatee movements and habitat use? 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...

Analysis of body condition indices reveals different ecotypes of the Antillean manatee 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...

Diving and foraging behaviors Diving and foraging behaviors
Manatees and dugongs live in tropical and semi-tropical regions around the world. Their preferred habitats are seagrass beds, rivers, lakes, and estuaries. Manatees live in both freshwater and marine systems although habitat preferences vary across the three species, while the dugong is entirely marine. Sirenians are shallow water divers, and their dive durations are short compared to...

Traveling to thermal refuges during stressful temperatures leads to foraging constraints in a central-place forager 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)...

Coastal habitat change and marine megafauna behavior: Florida manatees encountering reduced food provisions in a prominent winter refuge 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

Surveys of environmental DNA (eDNA): a new approach to estimate occurrence in Vulnerable manatee populations Surveys of environmental DNA (eDNA): a new approach to estimate occurrence in Vulnerable manatee populations
Environmental DNA (eDNA) detection is a technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. For eDNA measurement, genetic material shed into the environment is concentrated from water samples and analyzed for the presence of target species. Cytochrome bquantitative PCR and droplet digital PCR eDNA assays...

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. To aid managers at the refuge and other agencies with this task, spatial analyses of local...

Tagging and tracking Tagging and tracking
The number of stranding response facilities for marine mammals in the United States has increased over the past two decades, resulting in thousands of rehabilitated marine mammals released back into the wild (Geraci and Lounsbury 2005; Moore et al. 2007; Johnson and Mayer 2015; Simeone et al. 2015). All rehabilitated marine mammals released in the United States must be tagged or marked...

Consortial brown tide − picocyanobacteria blooms in Guantánamo Bay, Cuba 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...

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.
Winter Manatee Foraging Behavior and the Decline of Seagrass Beds in the Northern Indian River Lagoon
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.
