This research will evaluate possible behavioral distinctions of manatees to oncoming water vessels with individual variation, such as manatees raised in captivity opposed to wild, multiple boat scars versus no noticeable boat scars, and age class variation. Geographical comparison of multiple species of manatees will determine behavioral disparity in areas with high watercraft mortality and areas where the threat is less predominant. An array of behaviors will be analyzed including communication, predator response, and feeding. This research will strongly build upon previous research, and has robust conservation implications for capture and release, as well as rehabilitation programs for this endangered marine mammal. The Environmental Science and Policy doctorate program at George Mason University will grant me the expertise needed to excel in this field of
3. Metabolism a. Manatees are heterotrophic, so they have to find other sources of food because they can't produce their own.
Imagine a world of chaos. We see things like that all the time in movies, where zombies roam the earth and there are just those few main survivors left. The world is in ruins. If ocean life was to die out, there would be a collapse of civilization as a
Maya D Manatee Paper Like elephants, manatees never forget. This means that anything that happens to none manatee will remain in it’s mind for ever. Every day manatees are being injured by people. They are harmless creatures that rely on us to keep them safe . I believe that manatees need more protection because they are already endangered and they have no way to fight back.
This exceptionally charismatic megafauna has become synonymous with Florida along with “snowbirds”, orange juice, and Mickey Mouse but the Florida manatee may not be as permanent as its counterparts. Since being declared as endangered, the Florida manatee, a subspecies of the West Indian manatee, has been at the center of
U.S. Geological Survey’s Sirenia Project has been monitoring welfare biomarkers in manatees over several years in Kings Bay, Florida. Dr. Bob Bonde, a research biologist with the Sirenia Project, is granting the use of these samples for my proposed project. Identification and documentation of age classes of manatees at Kings Bay will account for manatees adapting to human interactions at these study sites over time. Thus, age may be positively correlated with lower welfare biomarker concentrations in samples. Fecal and blood samples will also be collected from captive manatees in swim programs at Isla Mujeres’s Dolphin Discovery Center with cooperation from staff members. Hypothesis 1: Human interaction induces negative physiological responses in the West Indian manatee, as indicated by welfare biomarker concentrations from fecal and blood
When introduced to the question of what is killing the Manatee, one can find that the topic can branch off into many different categories of threats. Those threats are listed as follows: human pollution, power plant run offs, canal locks, flood control structures, entanglement in fishing gear, etc. (Reynolds 25). As one can see, this subject can be very broad, therefore this paper serves to concentrate its focus on the specific role that humans and the operation of powerboats play in the decline of the manatee population.
In a documentary film directed by Bill Wisenski, “Threatened: The Controversial Struggle of the Southern Sea Otter,” it reveals some of the reasons why the California sea otter population is declining. In addition, it shows the controversy surrounding the “No Otter Zone”. Furthermore, it ensures why the California sea otter population is important to the marine ecosystem. In the film, sea otter populations are endangered because of the significant impact by some human factors. In the 1700’s and 1800’s, fur traders hunted sea otter population to near extinction. Besides this, threatened events such as shipping and drilling oil across the Pacific and along coastal areas; the California sea otters is vulnerable to oil contamination. As a result,
The sirenia’s habitat is located in the warm coastal waters. In fact, manatees cannot live in water colder than 68℉. They can be found where there is an abundance of seagrass or vegetation. This species can live in either freshwater or saltwater and are usually by boating docks. They migrate to near the equator in the colder months. During the summer months, they travel as far north as Massachusetts and as far west as Louisiana and Texas. Manatees are seen in coastal
The government has listed the manatee as “endangered” since 1972. When animals are listed as endangered, laws must be made to protect them.
Introduction: In recent years, animals in captive environments such as zoos and theme parks have grown more controversial. The literature I have reviewed focuses on a particular group of animals in captivity, cetaceans. Cetaceans include whales, dolphins, and porpoises. The literature includes a range of themes, from their unique level
According to Florida Fish and Wildlife Conservation Commission’s (FWC) Preliminary Manatee Mortality Report, 2016 resulted in the greatest number of manatee mortalities due to watercraft collisions . Watercraft collisions are the greatest threat to the Florida manatee (Trichechus manatus). In January of 2015, the U.S. Fish and Wildlife Service (USFWS) purposed to downlist manatees from endangered to threatened under the Endangered Species Act. However, downlisting is only permissible if the threats to an endangered species survival have been mitigated. Given the preliminary 2016 manatee mortality data, the major threat to manatees has been increasing not decreasing.
These are persons in their developmental stages. Reaching out at the right moment in developmental years is crucial to impressing sustainability upon our youth. These impressions are lifelong necessities that will extend the livelihood of our environment and more specifically, sea turtles. According to a recent finding in the U.S. National Library of Medicine,
The Blanding turtle are freshwater medium sized turtle usually found in The Great Lakes Regions in USA and in Canada. They are from the omnivorous species and usually eat crayfish, small animals, and plants. Their life histories traits occurs between April and November, as May and April tend to be more for mating and Early June for nesting. Less than half of these females will actually go on to reproducing. Many of these turtles can actually live up to sixty to a hundred years in age. Though these turtles spend a majority of time in the aquatics they also come on to the mainland. This is were the problem starts to occur and this is why the Blanding sea turtles are currently threatened and may soon be extinct. It is because of us humans that these species are currently facing habitat loss, have threatened nesting areas, and are unable to get from nesting areas to the lakes because of manmade roads. Why should we as humans care so much if these Blanding’s turtles go extinct? These turtles play an important
I think that tourists should be allowed to swim with the manatees. According to the article, most tourists are respectful and listen to the instructions that their tour boat captains have told them. Mike Burns, a man who lead tours to manatee viewing spots around Kings Bay said, “Someone comes back to the boat, and she’s just bawling: ‘Oh it was great! It came right up to my face!’ She’s so overcome by emotion she can’t wait to go out and save the manatees. I’ll tell you, for a lot of people, it really is a spiritual experience( “A Manatee Story” ).” Many people leave Kings Bay with a heightened appreciation for manatees, and some have become manatee advocates. So, when people abuse the manatees, new regulations are quickly put in place because
