Hawkbill Turtle Research Paper

Now, as most may know sea turtles are both marine and land animals depending on what stage of life they are in. Which means that they need to be able to go on land during certain stages of their lives. One of the main reasons why a sea turtle will go on to land is to lay their eggs. Within the last few years this has become harder and harder for the already endangered species. It

Ocean pollution is caused by many things,plastic,humans, and oil spills, we are trying to stop this. So many people just put the plastic in the ocean and people are trying to stop them. Two billion people within 30 miles of the coast create 100m of coastal plastic waste. We can help by reducing plastic in waste stream, and try to stop pollution. Another way we can help is by recycling (Doc.1). We cause pollution to by dumping trash and garbage onto beaches. We have to help protect oceans by monitoring the water to see if people can go swimming (Doc.2). The oceans have to stay healthy because they are a habitat to animals (OI). Another reason we have to keep oceans healthy because they are a big food source for us (OI). In

Ocean pollution is such a broad topic, and one that has many facets to it. As a group, we found it to be a very intriguing topic that it relevant to our everyday lives. As New Jersey residents, we have all spent time at the Jersey shore. We have all enjoyed the small and big beach towns, the sand, and of course

Earth's oceans are dying. “About 80% of the ocean around the world is polluted with chemicals industrial and residential waste, all of which comes from the land” (“Marine Problems…”).  Pollution is mainly coming from the people. Marine pollution should be stopped because it is the cause of many problems and if something is done about it, people will see an increase in sea life and healthier waters. It makes its way into the ocean and kills marine life. Ocean pollution is affecting the way of fisherman and their everyday lives. It is also very bad on the community because pollution is very bad on tourism. Ocean pollution should be stopped because it is poorly affecting marine life, it is not good for fishermen, and is very bad on tourism.

The Red-bellied Cooter is being threatened by both man-made and natural causes. Do to economic growth, areas that used to be a good habitat for these turtles are now being turned into new, buildings like apartments, houses, and stores. In areas where the turtles can live, they are threatened before they have even hatched from their eggs by other predators like raccoons, skunks, or even snapping turtles. Almost all of the eggs in a nest are harmed before they have a chance to hatch. So while humans taking up land takes the Red-bellied Cooters’ homes, their predators take their lives.

Endangered Species Act and also appear on the list composed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Human Predation-Though most countries find harvesting sea turtles for food illegal however, these laws are not enforced. U.S. shrimpers are required to put Turtle Excluder Device on their trawl nets since in the past shrimping nets have killed fifty thousand turtles annually. Nothing endangers them the most then plastic bags or helium balloons floating in the water. Effects of consumption include interference in metabolism or gut function. Temperature, which may affect embryo development, in the last hundred years the temperature, has changed six degrees Celsius. The temperature causes the change in the distribution of species in the ocean due to the change in prey and food.

The green sea turtle occurs throughout tropical and subtropical oceans and is among the largest of the hard-shelled sea turtles growing to as much as 440 pounds and four feet in length. The breeding populations in Florida were listed as endangered in 1978 (43 FR 32800 32811, July 28, 1978) whereas all other populations were listed as threatened (NOAA 2015h). There is a proposal for identification of a North Atlantic green sea turtle distinct population that would be listed as threatened, continuing its current listing status near New York (80 FR 51763 51764, August 26, 2015). They are found in the shallow waters (except during migration) of shoals, bays, lagoons reefs, and inlets, often where submerged aquatic vegetation exists, from Maine south to Florida, and throughout the Gulf of Mexico and the Caribbean Sea (USFWS 2015n, 2015o; NOAA 2015e). Green sea turtles nests are not present in New York; however, they occasionally are found stranded on or near the shore (NYSDEC 2015ad). Breeding takes places in subtropical to tropical oceans every two, three, or four years between June and September, with peak nesting in June and July (NOAA 2015h; USFWS 2015u). Hatching usually occurs at night, and many green sea turtle hatchlings seek refuge and food in masses of floating sea plants (USFWS

Basically everything that is caused by humans has impacted these turtles. How can we help? First we need to protect the wetlands that are slowly being killed. “The greatest threats to the bog turtle are the loss and fragmentation of its habitat” as stated by the U.S. Fish and Wildlife Service so, by slowing down the destruction of the wetlands we might create a better and bigger environment for the bog turtles. Next we need to identify the sources that are harming the turtles and the wetland habitats. This means we need to find the exact problem and fix it. Finally we need to restore the environment where the turtle used to live, and by doing this we can restore the turtle population back to non-endangered

Loggerhead eggs and hatchlings are a large food source for a variety of terrestrial animals, nearshore predatory fish, and seabirds, providing substantial amounts of energy and nutrients for these species (Wilson et al. 2010). A five or ten year period of loggerhead turtle declines may cause sublethal effects such as decreased growth rates or reproductive output for these predator species and a fifty year period of loggerhead turtle decline may potentially have more severe impacts such as significant declines for local populations that rely on eggs and hatchlings as a food source.

The Graptemys caglei, also known as the Cagle’s Map Turtle, is an endangered turtle species found in San Antonio, Texas and along the Guadalupe River. It identifies easily by the pattern on its shell which resembles an aerial view topography, as well as its spiked shell edges, which are not as sharp as other map turtles of the same genus. Although the Cagle’s Map Turtle has natural predators pose a threat to the individual turtles’ lives, the predators are not a greater threat than habitat disturbances created by humans. Unfortunately, this species suffered a significant drop in population since the mid-1970 through changes in its habitat disallow support of a larger population of the turtles(van Dijk, P. P., 2011).

Sea turtles are becoming more and more endangered as time goes on and is something that really needs to be changed. There are seven species of sea turtle and they are all either endangered or critically endangered. Millions of sea turtles used to inhabit the sea now only a fraction of them are still around. Humans are partly the cause of this because we hunt them for food and profit. It is unbelievable that people can kill such beautiful creatures just for their personal benefit. Humans are not the only reason sea turtles are facing extinction, but we are the main reason. Humans really should not be part of the problem in the first place.

Everything in this world we use comes from the ocean in some way. The air we breathe, the water we drink, even the products we use day to day, would not be possible without the ocean. That's why the issue of ocean pollution is so important and needs to be addressed as soon as possible. We depend on the ocean for so much in our life, without it we would surely become extinct. People seem to think that since the ocean is so large and vast, we can dump as much waste as we'd like into it and it will never have an effect on us. However, since we've been polluting the ocean as far back as Roman times, the evidence of ocean pollution becoming a major problem is all too clear.

In the original listing from USFWS (1978), the loggerhead sea turtle was listed as threatened throughout all of its range. The document goes on to state that one of the main threats to the loggerhead sea turtle was that it was being harvested for the shell or as food; the eggs were considered a desired food item and protein source. Regulations were put in place to protect the loggerhead sea turtle such as prohibition of foreign commerce, importation, and exportation

The turtles are the only species in the ecosystem that can eat the poisonous sponges that suffocate and poison coral reefs. These turtles are one of the rare animals that can eat the poisonous sponges without being harmed; the unique structure of their mouth and flexible neck allows them to eat the sponges out of every crack on the coral reef (Edelman, 2004). “Since 1970, researchers from the National Marine Fisheries Service have claimed that the Hawksbill turtles population have declined. The turtles were officially classified as endangered in 1970” ( NOAA Fisheries, 2014). Toxic sponges reproduce quickly and take up any empty space on the coral reefs. Brandis states, “if the Hawksbill turtle were not around to consume the sponges, the coral reef would not be able to survive” (Brandis, 2010 a). By constantly picking off and consuming the sponges, the turtle also makes space for other sea creatures to live on the reefs. If the coral reefs die, the poisonous sponges will have no place for shelter; they too will be impacted by the loss of the Hawksbill turtles. This underwater habitat as a whole will be disrupted by the decline in the Hawksbill turtles (Brandis, 2010

The oceans face many types of pollution every day, every second. The ocean is our greatest ecosystem and out most valuable resource. A common misconception is that the rainforests are the lungs of the planet however, the majority of our oxygen is made via the algae in the sea. The oceans feeds, hydrates, and provides us with oxygen; ironically enough, despite its monetary value to mankind, it is what is treated the worst. For ages we have been dumping our trash, chemicals, and waste into the oceans with no fear or regret, almost an “out of sight- out of mind” mentality. People once and still assume that the oceans are so vast that all of the pollution is diluted and would be dispersed through out, going unnoticed. However, dilution is a myth and an idea that renders ocean dumping to be less impactful. Even so much of the man made pollution is becoming even more concentrated and have entered our natural food chain. However vast the waters of the ocean are, they are not meant to house all of these external factors. There are many alternatives to marine pollution including recycling, finding alternative trash dump sites, cutting down on harmful chemicals for agriculture, and most importantly having the ability to recognize when a problem is developing and counter act, immediately.
