ABSTRACT The critically endangered Hawksbill turtles play an incredible role in maintaining a diverse underwater ecosystem. There are various factors that have impacted the endangerment of the turtles: the biggest one being humans. The Hawksbill turtles are one of the rare species that are not harmed by the toxins of various sponges that grow on coral reefs. The turtles eat off the excess sponges that are dangerous to the coral reef ecosystem. Without the turtles, the sponges have the ability and strength to overtake the coral reefs and possibly cause their extinction. This research proposal explains the endangerment of the Hawksbill turtles, their role in balancing the coral reef’s ecosystem, how the Hawaii Wildlife Fund is attempting to …show more content…
This is the case for the Hawksbill turtle. Nahill clarifies, “people use the turtles’ unique shells for jewelry and other beauty accessories. The Hawksbill turtle is an endangered species, with human impact being the leading cause of its endangerment. Since humans are the cause of their endangerment, it is our duty to raise awareness of such harm before it is too late” (Nahill, 2008). The Hawksbill turtles are commonly known for their beautiful shell. The turtles are captured and killed so their shells could be sold. The shells sell for around $220 per kilogram (Weisler, 2005). As these turtles are being captured and killed, leading them to near extinction, we need to understand the overall impact their extinction will have on the underwater …show more content…
They currently work off the Hawaiian coast to observe and study the daily life of the Hawksbill turtle. They watch how the Hawksbill survives both on land and in the ocean. On land, the researchers focus on the breeding and eggs of the turtles. They block off the areas where Hawksbill turtles have made their nests. They also watch the hatchlings dig out of the nest and their journey into the water (Bernard, 1996). At times, hatchlings mistake the beach lighting as the sun and head toward the lighting instead of the water, which makes them easy prey (National Wildlife Federation, 2015). In the ocean, the researchers have mounted satellites and radios that capture the underwater activities of the turtles (Bernard,
In the Grapes of Wrath, a novel by John Steinbeck, there are many examples of symbolism. One of the most prominent symbols found in this book is the turtle seen in chapter three. This turtle is symbolic of three things: the Joads and their journey west, Tom Joad himself, and the promise of new life. First, here’s a little background information on the turtle. This land turtle was somewhere to go. Where than is, no one knows, except perhaps John Steinbeck. To get there the turtle decides to take the perilous journey down a dusty dirt road that stretches along the quiet countryside. What could happen? A lot more than one might think. In fact, the turtle faces quite a few challenged ranging from pesky insects, to ledges, to even cars. But, the thing that makes this turtle special is that he never gives up (Pages
Throughout the animal kingdom, adaptations take place continuously and even the smallest of changes can leave a significant impact. Examples can be seen within any plant or animal. One example would include sea turtles, specifically, the Loggerhead Turtles. These turtles are native to the Indian, Atlantic, and Pacific Oceans as well as the Mediterranean Sea (Deurmit L 2007). They thrive in either temperate or tropical climates and can live in a myriad of biomes (Deurmit L 2007). These biomes include the pelagic, reef, coastal, and brackish water (Deurmit L 2007). Loggerhead turtles are omnivores and can eat anything from insects to aquatic crustaceans, to macro algae (Deurmit L 2007). According to Deurmit (2007) Caretta caretta is classified into Animalia Kingdom, Chordata Phylum, Vertebrata Subphylum, Reptilian Class, Testudines’ Order,
The efforts taking place through different conservation organizations and the State of Florida are making a mixed impact on the survival of Manatees and Sea Turtles. The decline in manatee population has decreased, but due to low reproduction rates, more needs to be done to avoid extinction. The sea turtle outlook is more species specific. Some species of turtle are seeing stabilization in population, while others are not. The State of Florida has a large array of custom license tags that support the conservation efforts taking place within the State. The proceeds go to benefit the local marine life in Florida. With financial resources, state and local cooperation, and through constant research and observation, we are able to learn more about both of these gentle animals. With human awareness of those living in Florida, these two animals will survive
...t the guaranteed developmental boom following the completion of the project will also ensure an even greater and more damaging human impact as there will be more beachfront lighting, boats, and beach pollution. Unconcerned with the negative ramifications of the beach nourishment project, islanders on Topsail prove their allegiance to development, tourism, artificial beaches, the promise for a more booming economy and the selfish desire for hurricane protection even though they riskily built homes on one of the most hazardous and unprotected barrier islands in the United States. Topsail’s willingness to betray the environmental protection organizations it’s worked tirelessly to support makes me question whether the promotion of the Topsail Turtle Project and the Turtle Hospital was a noble cause to save endangered animals or a farce to attract the media and tourism.
...rients and balance sea floor sediments. Many environmental and government run programs have been created to help the efforts of saving sea turtles. Some of the actions include making mass fishing companies use safer methods to prevent catching turtles, ordinances that control lighting along beachside properties, and small groups protecting nests from their creation to hatching. In addition to these measures, wire mesh gratings are put over the nests in order to protect them from being scavenged by foxes (Kurz, Straley, Degregorio, 2011). Although these efforts do make a positive impact, loggerhead’s migration patterns are so vast and worldwide that it is almost impossible to truly enforce conservation efforts. This is because sometimes they can be seen as an “inconvenience”. It is important that we strive to protect this important component of the ocean’s ecosystem.
Evolution is a process of living things change slowly in a very long time, so it evolved into a new species more complete body structure. According to the theory of evolution, living now in contrast to living in the past. The ancestors of creatures alive today may experience changes in form and structure. In addition, may experience changes in both the structure and genetics in a very long time, so the shape was totally different from the original and finally generate different types of species present. So the plants and animals living there now was not the first time here on earth, but it comes from living in the past.
Corals provide shelter for nearly one quarter of all known marine species. The reefs are home to over 4000 species of fish, 700 species of coral, and thousands of other forms of plant and animal life. Living coral reefs are the foundation of marine life, and this also means that they are essential for human life, but all over the world they are dead or dying because people are destroying them at a very fast rate. Already 10% have been lost, and there are predictions that 705 of all corals on the planet will be destroyed in 20 to 40 years unless people stop doing what they are doing now – i.e., pollution, sewage, erosion, cyanide fishing, bad tourism.
All over the world coral reefs play an important part in our environment. Not only are the reefs colorful and beautiful to look at but the coral reefs house several different types of fish and other sea creatures. Coral reefs have started to decline over the years due to “climate change, El Nino events, overfishing, pollution and other pressures” (Newnham 1). A healthy coral reef can also collapse due to a natural disaster (Newnham 2). There can be several different reasons why a coral reef has started to decline or has been destroyed.
When fishers throw their nets, the turtles get caught in the nets causing damages to their body or drowning them. When juvenile loggerheads head to their foraging area in the water, they are highly exposed to bycatching, international longlines, and illegal, unreported and unregulated (IUU) longline fisheries causing high mortality rates (Peckham et al. 2008). Though juveniles have a higher mortality rate due to bycatch, longlines and trade since they are still maturing, adults are easily exposed to these threats as
Fresh Water turtles are small, yet amazing creatures to have and care for in your home. River Cooters, Red Eared Sliders, and Painted turtles are all common pet’s found in America. Though turtles are fun to have around they do require special care just like any other pet would. In most cases they make great pets but turtles aren’t the easiest pets to have so depending on your lifestyle you should think about how much time you’re willing to put into a turtle. They are usually cheap to buy yet the equipment for your turtle can get expensive. Along with cost you must find the time to put into this pet. They need nice set ups to live in as well as attention and proper handling.

This article discusses how important the organisms symbiotic with coral reefs are, as well as how important coral reefs are to our environment. Also explained is how natural and non natural things things like hurricanes and overfishing affects them. A study is quoted about how water acidity also plays a role in the bleaching of corals. Lastly, restoration and conservation efforts are discussed and how we could possibly help our oceans.
Coral reefs are well known for their colorful array of marvelous sights including a parade of exotic flora and fauna. They are said to be the foundation for a quarter of marine species, and are a crucial support for human life as well. The coral reef ecosystem is a diverse collection of species (ranging from microscopic to larger-than-life in size) that interact with each other and their physical environment. If any piece of a coral reef is harmed or removed the entire community can be seriously affected, even to the point of collapse. Unfortunately, human impact has resulted in long-term stresses that, unlike the short-term stress of natural disasters, coral reefs are not as capable to recover from. “Approximately half of the world’s coral reef ecosystem resources are considered by scientists to be in 'poor' or 'fair' condition and have declined over time due to several anthropogenic threats” (“Status of Corals” par. 2). Through poorly administered commercial practices, carelessness and ignorance among the common people, and human aggravated natural processes coral reef destruction has become a serious issue afflicting the world’s biodiversity and it’s intricate biosphere mechanics (“Human Impact on the Great Barrier Reef” 1) (“What Are Coral Reefs?” 1).
In conclusion, I would like to say that before writing this paper, I had no idea how important coral reefs were to the earth. I have learned a lot and I think that if more people were informed about the positive capabilities of them, humans wouldn't be so careless about them.
Today many people do not see the need to preserve corals reefs. Hence because of the lack of appreciation for the reefs, they are slowly disappearing. Many citizens do not realize the importance of these reefs, the species they hold, and the food webs that connect the ecosystems. Our American government has stated many times that they are doing all they can to preserve and to replenish our coral reefs. However, how accurate is that statement? To answer these questions, we first have to understand what a coral reef is and how it can be saved.
