Georgia Endangered Species

Brooks and Dodson, the authors of the article titled “Predation, Body Size, and Composition of Plankton”, conducted research on the effect the small fish called Alosa Pseudoharengus has on an ecosystem, more specifically, different lakes in New England. Along with the data they collected on the aforementioned matter, they studied the sizes and the composition of the miniscule zooplankton inhabiting the lakes, and compared it with that of the Alosa. Their research uncovered important facts regarding water ecosystems and how they are so easily thrown off balance.

"There is proof that the manatees were around for about 60 million years and that they were related to the elephant. It was also learned that they were land animals and that over time they learned to survive in the water".

Iconic Cape Cod Massachusetts is named after the Atlantic Cod. For centuries, this fish has provided food and trade for New Englanders. In this time, there have been several instances of overfishing by humans from the aboriginal era to colonial times but none so drastic as the present conditions of cod fisheries (Jackson, Kirby, Berger, and Bjorndal, 2001). Overfishing is a human induced occurrence where humans are fishing more than a body of water can sustain. In other words, humans are catching more adult fish preventing the existing population from growing to replenish the fish that were caught (Overfishing: A Global Disaster, n.d.). Worldwide, over 80% of the fish stocks are “fully- to over-exploited, depleted, or in a state of collapse” (Overfishing: A Global Disaster, n.d.). The results of this careless behavior has reduced the biodiversity in the Gulf of Maine and landed the Atlantic Cod on the endangered species list as being “vulnerable” (Cod, n.d.). In the neighboring region of Newfoundland, Canada, communities are already feeling the effects of overfishing. In 1992, at the beginning of the fishing season in the Grand Bank region, there were suddenly no more cod. The local economies collapsed and to this day, the region has not quite recovered (Brennan and Withgott, 2005).

The Everglades National Park protects the largest wild life area east of the Mississippi River. The Everglades are the largest remaining sub-tropical wild life area in 48 states sitting on 1.5 million acres preserved at Florida’s tip off shore. The Everglades contain various ecosystems such as rivers, lakes ponds, marshes, etc. These wild life areas feature both fresh and saltwater areas, open prairies, pine rock lands, tropical hardwood forests, offshore coral reefs, and mangrove forests. This paper will summarize how humans contributed to the destruction of the Everglades and how man is working to save the Everglades. Since the Everglades is comprised of both fresh and saltwater areas the vast range of wildlife species in the Everglades include but not limited to reptiles, mammals, aquatic birds, etc. The vast spectrum of wildlife living in the Florida Everglades include but not limited to aquatic animals, mammals, reptiles, etc. Of this vast spectrum of wildlife living in the Florida Everglades there are 56+ species who are either endangered or are in jeopardy of being endangered. The Everglades are home to two National Parks, four National Wildlife Refuges, and one National Marine Sanctuary that bring almost 2 million visitors every year to experience this natural beauty located minutes from Miami Florida. The powerful environmental forces of sun, water, wind, and fire greatly affect the development and lifecycles of these

The conservation of Udubia is a significant issue that needs to be dealt with promptly. There has been a decline in the marine wildlife surrounding the islands, which leads to a greater question; Why is this happening and what can we do to help? For one, fishing is a major concern. South of Tacominone, and to the east is where many tens and hundreds of tons of lobster and Rockfish accordingly, as well as hundreds of pounds Yelloweye Rockfish are being caught, and simultaneously a decline in the population of seals. There is a correspondence in the increased fishing yield numbers to the decreasing seal population. The dodo observed that 90% of manatees off the coast of Florida have scars on their backs due to the propellers of fishing boats.

Last year alone over 15% of the Florida manatee population was killed by a human in a preventable way (Pittman). These preventable ways include polluting the waters, the use of fishing nets, and the wrongful usage of motor boats. Manatees have also been on the endangered species list since 1973. They first made it onto this list because their entire population

Many species vital to ensuring that today’s environment will thrive are becoming extinct. If a species is slowly dwindling, and in imminent danger of becoming nonexistent, this species is considered to be endangered. “One in four mammals, one in eight birds, one third of all amphibians and 70% of the world’s assessed plants on the… IUCN Red List are in jeopardy” (IUCN, 2016). According to the International Union for Conservation of Nature, or IUCN, upwards of 16,000 species are threatened with extinction, including both plants and animals (IUCN, 2016). Before becoming endangered, a species will show warning signs, either by starting to lose biological diversity or by losing the habitats for that species to flourish in, or in the worst case, both. The word endangered can sometimes be confused with threatened, extirpated, or extinct. Extirpated refers to the state of a species where its population has died out in a certain area or range, but other populations of said species still exist elsewhere (Olden, Julian D., 2008). When a species is considered threatened, or vulnerable, this refers to the state of the species being susceptible to endangerment and extinction (“Extinction crisis escalates”). So if a species is threatened, the first signs of endangerment come along, which are similar signs to that of a species in danger of becoming threatened, including lack of genetic diversity, or overhunting may be evident. (“Extinction crisis escalates”). When a species is labelled

The Columbia River Limpet, otherwise known as the Short-faced Lanx, is endangered due to human causes. This species is endangered due to population fragmentation and isolation, dam-building, and many other human causes. In addition, habitat loss is one of the biggest problems because this organism has such specific habitat requirements. This species lives in a freshwater ecosystem and now, large populations can only be found in 4 streams. On the other hand, these human-induced problems can be remedied with a few restrictions, support, and a little effort.

The Florida Everglades is the state’s most highly visited park in the state. The Everglades is also home to thousands of animals, reptiles, and plants. Many tourist travels just to get a glimpse of the many exotic reptiles. Although, the Everglades is very beautiful it’s also one of the most endangered parks in the state. The park is endangered from humans and land developments. The state has laws imposed to protect the everglades. In order for people to save and protect the Everglades there are things we have to do on part. Throughout this essay I will go into depth about the different species, human threats, and what we can do to protect one of our

Many of its marshes, cypresses, and mangroves cover the majority of the wetland and an estimated number of 50 reptile species and 40 mammal species currently residing are either endangered, or worse, threatened for extinction. The Florida Panther, according to the National Park Service, has a successful breeding population; nonetheless, the “primary threats to the remaining population are habitat loss, fragmentation, and degradation” (para. 2). Due to the ongoing urban development, the panther became a well-known endangered human threat. An estimated 80-120 panthers are surviving

The area of research that I have selected is the effects of overfishing in the Sea Otter ecosystem off the coast of California. The effects caused by the fishing pressure on the ecosystem will have different outcomes, depending on the strength and the types of relationships of the organisms present. (4) Red Abalone populations have declined drastically, to the point of the abalone fishery collapse. Several factors have led up to the collapse including Withering Syndrome, where the organism loses the ability to attach itself to rocks, making it more susceptible to predation, or the organism can eventually wither and starve to death. Sea Urchins and Red Abalone are a part of the same ecosystem, and are competitors of each other.(5) Both organisms graze on macroalgae and are a primary food source for Sea Otters. Sea Otters occurred from the North Pacific Rim down to Baja California, Mexico, but now only occur in small isolated patches (9) It is understood that Sea Otter presence can characterize community structure, where they can control and determine the size of Sea Urchin and Red Abalone populations. In the absence of Sea Otters, “Urchin Barrens” are created from the overgrazing of macroalgae by Sea Urchin. In these areas the ecosystem have changed dramatically, due to the overfishing, or in this case the over hunting, of Sea Otters causing a trophic cascade.(7)In some areas, Sea Otters have been reintroduced, in other areas they were never removed, and in others they

In 2016, a record number of manatees in Florida were killed by boaters, 400 deaths. There are over 1 million registered boats in the state of Florida, and it is not necessary to take any type of manatee education. With the population of Florida rising, it is imperative that boats wishing to use our waterways be educated in the ways to protect the manatees.

Mason Neck Park and Mason Neck Wildlife Refuge, officially known as Mason Neck State Park and Elizabeth Hartwell Mason Neck respectively, are home to a multitude of species, such as the bald eagle, the Virginia pine tree, and the white-tailed deer (“Elizabeth Hartwell Mason Neck,” 2016; “Mason Neck State Park,” 2016). Critical to the conservation of endangered species, Mason Neck Wildlife Refuge, run by the National Wildlife Refuge System, a part of the U.S. Fish and Wildlife Service, provides a safe habitat for the various organisms (“Elizabeth Hartwell Mason Neck,” 2016). On the other hand, the Virginia Department of Conservation and Recreation, the governmental agency responsible for Mason Neck Park, keeps human’s recreational needs in mind and provides activities such as canoeing and fishing (“Mason Neck State Park,” 2016). The human interference present within the Mason Neck Park may impact the local ecosystem (“Mason Neck State Park,” 2016). Although there are activities available in Mason Neck Wildlife Refuge, they are “wildlife-oriented recreational developments” meaning the well being of organisms living in the Refuge will be the first priority (“Elizabeth Hartwell Mason

Cetacean bycatch is an ongoing problem in the oceans of the world. Cetaceans are defined as whales, dolphins and porpoises(CBRC 1). Bycatch is “marine mammals that are “captured” but discarded”(Read 2). This happens when fishing industries are fishing for a certain type of marine animal and other marine animals are caught accidentally along with the intended catch. Many times, this leads to the death of the animal that was not meant to be caught, and the animal is tossed back into the ocean. This happens with all kinds of marine life, and it has caused the depletion of many different species. However, this is specifically bad for cetaceans, such as dolphins and whales, because they have such a long lifespan(Brown 2). They also take a very long time to mature(Brown 2). These factors make catching these animals very detrimental to the species as a whole because it takes longer for them to reach an age where they can reproduce(Brown 2). The population of many cetaceans have decreased exponentially. When there is someone watching the nets that cetaceans are accidentally caught in, many times they can be saved. However, there are only select few types of fishing methods that do this, and they are not of the prevalent fishing methods that produce cetacean bycatch. This is a problem because there is a connection between most living animals. If a certain part of the connection is eliminated, it will all fall apart. For example, the relationship between

How often do we stop and think about the people that fish to provide the rest of the world with the supply of fish that is in demand. With many fisheries closing down due to poor managing and depletion, anglers are turning to the deep sea to fill their “fish orders”. Large fishing vessels also known as Super Trawlers are dragging fishing nets up to a mile deep. Doing this allows them to catch as many fish as possible, but it is also destroying natural habitat such as coral reefs that have been part of the sea for thousands of years. The effect of this is devastating to sea life.
