given off by power plants throughout the winter months. However, as older plants are replaced with more energy-efficient structures, manatees could become at risk of cold-induced death due to reduced availability of warm-water refuges. Manatees exhibit high site fidelity and can recall previous refuge sites to which they frequently return in successive winters. Some conservationists fear that manatees may become overly reliant on warm-water locations generated by power plants that may shut down soon. Natural warm-water springs face problems from over-pumping of groundwater for human consumption, reduced spring flow, and nutrient pollution. In addition, some springs that were historically accessible to manatees are blocked off by dams or other structures. As
Florida moves towards net zero by 2050, power companies will likely phase out these warm water discharges. Florida Climate Instituteâs Laying the Groundwork for âGetting to Neutralâ in the State of Florida project sets a foundation for a net-zero action planning effort in Florida by 2050. In areas where manatees lack access to power plants or natural warm springs, they instead seek out natural deep water zones that passively remain above tolerable temperatures.

strikes. Manatees can hear boats, but they oftentimes do not have enough time to get out of the way of a fast approaching boat. A boat going at a slower speed gives the manatee more time to react and move out of the way. Manatees respond to approaching vessels by orienting towards deeper waters and increasing their speed, but they are nevertheless frequently struck as they don't have the ability to swim very fast and, in shallow habitat, they oftentimes don't have anywhere to go to get out of the way. Over half of all watercraft deaths are caused by the impact trauma from the hull of a fast-speeding boat, whereas the remaining percentage is caused by the boat propeller. Aerial surveys of
Florida manatee and boat distribution have been conducted to map the areas in which collisions are most likely to occur, accounting for environmental and seasonal factors. Watercraft can frequently avoid hitting manatees simply by reducing speed, allowing time for the manatee to escape out of range. Despite improvements in modeling and changes to local regulations, manatee mortalities from watercraft collisions continue to rise, with an all-time high of 137 recorded deaths in 2019.

exposure to red tide if rescued and rehabilitated in time, researchers fear that there might be long-term effects from sub-lethal red-tide exposure, which can affect the manatee's immune system through reduced lymphocyte proliferation response. In addition to red tide, blue/green and brown algae blooms triggered by excessive nutrient pollution from fertilizer, runoff, and leaking septic tanks can cloud the water. This results in seagrasses dying off since seagrasses and aquatic plants need light to photosynthesize. Manatees in turn may not be able to find sufficient food sources, which can lead to starvation. Manatees have experienced several
Unusual Mortality Events (UMEs) over the years, which are usually related to either cold-stress syndrome, or brevetoxicosis from red tide. A current UME is ongoing along the Atlantic coast of Florida and is most likely related to a shortage in food sources.
838:, and the male contributes no parental care to the calf, which remains with the mother for up to two years prior to weaning. Female manatees have two axillary mammary glands located under their flippers. The lactation period for mothers and their calves last typically for one to two years. Prior to weaning, there is an increase in the hormone progesterone in the mother. During this two-year period with their mother, calves learn how to locate warm water sources for winter and about migration routes for the summer seasons. A single female can reproduce once every 2â3 years, which is referred to as the calving interval. Wild manatees have been documented producing offspring into their late 30s, and a female captive manatee has given birth in her 40s.

several males aggregate around an estrous female and compete for access to her. These mating herds can last up to 2 to 4 weeks. The estrous cycles of female manatees typically are approximately one month long. Females in captivity have been observed to skip cycles. Larger males, presumably older, have been observed to dominate mating herds and are likely responsible for most successful copulation events. However, between males and females there is a little sexual dimorphism where females are typically slightly larger than males.

746:. Unlike other hindgut fermenters, such as the horse, manatees efficiently extract nutrients, particularly cellulose, from the aquatic plants in their diet. Manatees have a large gastrointestinal tract with contents measuring about 23% of its total body mass. In addition, the passage rate of food is very long (about seven days). This slow process increases the digestibility of their diet. It is suggested that chronic fermentation may also provide additional heat and is correlated with their low metabolic rate.

individuals. The U.S. Fish and
Wildlife Service estimated in 2017 that as many as 6,782 individuals might exist in the Antillean subspecies, but these results rely in large part on personal anecdotes and may overestimate the true population number. A 2012 study of the Antillean population documented significant human-related causes of mortality, and projected that if the share of human-caused manatee deaths per year rose to 5% or more, the population would face a severe decline and eventual extinction.

vocal individuality among manatees. An increase in manatee vocalization after a vocal playback stimulus shows that they may be able to recognize another manatee's individual voice. This behavior in manatees is found mostly between mother and calf interactions. However, vocalization can still be commonly found in a variety of social interactions within groups of manatees, which is similar to other aquatic mammals. When communicating in noisy environments, manatees that are in groups experience the same
