...Introduced Species - The Red fox Introduction The vulpes vulpes or other words known as the red fox, was introduced to Australia in the early 1870s for recreational hunting purposes. The spread of the red foxes were closely followed by the distribution of other pests for example, rabbits. Today, these vicious creatures are found in most mainland areas South of the tropics and, unfortunately, are even believed to have been deliberately distributed to Tasmania. (Animal Control Technologies, 2013) Biology Introducing red foxes into Australia increased the biodiversity of the animals. They helped keep the population of some pests intact. The red fox is important in the energy flow...

...Environment and the Law – Native Animals Good morning/Afternoon Miss Morris and students. The purpose of this presentation is to discuss the major threats to Australia’s wonderfully diverse native fauna. Key threats include climate change, urban development and habitat lost, however, the 2 that will be discussed is wildlife trade and kangaroo culling. Current legislation will be analysed as well at the action/inaction of the government, followed by case studies to support and concluding with suggestive recommendations. Australia is one of the most important nations on Earth for biodiversity. In fact, Australia is one of only 17 “megadiverse” nations and is home to more species than any other developed country. The primary factors causing...

...in different spots around the world. For a species to be invasive it means that the species is not native to it’s current location and the species will often cause damage to the environment, human economy, or human health. Feral pigs are native to Asia and Europe, but were brought to Australia by European explorers and settlers. At first, the pigs were used as domesticated companions, but as they escaped captivity, they began reproducing rapidly and creating a large wild pig population. Now, the feral pig population has become a widespread problem across Australia, costing their economy millions upon millions to try and fix what the pigs are destroying. The feral pigs...

...FERNANDEZ, Sam T401 MWF 330-430 BS HTM TTM 4 10 September 2014 AUSTRALIA 1. Southern corroboree frog - Pseudophryne corroboree IUCN listing: Critically Endangered Inhabiting a small corridor on the New South Wales and Victorian border, the tiny southern corroboree frog - which is the size of a fingernail - is running on the edge of extinction. Fewer than 150 breeding males are thought to survive across 23 sites that were surveyed in 2001. The main suspected threat is the chytrid fungi. Although many studies have been undertaken, the success has been limited, as they have not been able to confirm the critical threat to the frogs. A studying conducted between 1997 and 1999 revealed that the frogs were present in 213 sites around the NSW and Victorian border but this number dropped only 79 sites as of 2001, revealing how quickly these animals were disappearing. A captive-breeding program, led by Sydney's Taronga Zoo, reintroduced 800 eggs into Kosciuszko National Park in 2012. 2. Margaret River burrowing crayfish - Engaewa pseudoreducta IUCN listing: Critically Endangered With only two known populations, the Margaret River burrowing crayfish is highly endangered. Even one of these may no longer exist, as there have been no sightings since 1985. The threats are almost all attributed to human activity. Land clearing is the biggest danger, as crayfish habitat can be eroded or contaminated by farming, mining and urban development. Feral pigs also damage habitat...

...Endangered Species Our planet earth has produced many wonderful and bewildering things. Our planet was once lush of vegetation, plants and amazing animals. There are numerous plants and animals that are now extinct, either due to natural selection, climate change, or urbanization. Knowing this, we should not take advantage of what earth has to offer, this includes animals that are now endangered species. According to Richard T. Wright, “endangered species is a species that has been reduced to the point where it is in imminent danger of becoming extinct if protection is not provided (page 254). Although some animals may seem unimportant to most, many of these animals are what help keep the earth’s ecosystem in equilibrium. There is much controversy on endangered species and the devastation of their habitats. Before someone establishes their own opinion on the subject matter, it must be understood what an endangered species is and how it came to be, along with the controversy between it. Endangerment is a very broad issue that involves habitat, the surrounding environment and the interaction between other species. There are many factors that have lead to endangerment and possible extinction to earth’s animals. One of the biggest factors is habitat destruction. Habitats are constantly changing due to the earth’s constant change in climate and movement, although that is only a slight change. The biggest component to habitat destruction is the result from human activity...

...Endangered animals are those species that are in danger of going extinct. Their reproductive rates are lower than their mortality rates over long periods of time, so their numbers are diminishing. The reasons for this are varied, but lately, very often involve a loss of habitat as people encroach on their living areas. When a species is listed as endangered or threatened, it is not a death sentence. Many animals, like the bald eagle and the American alligator, were on the brink of extinction and are now recovering. Many species, however, will not recover, and could be lost forever. Throughout time, animal species have been going extinct (long before people evolved); paleontologists estimate that well over 90 percent of all plant and animal species that ever existed have gone extinct. The Koala is a small marsupial that lives in eucalyptus trees in Australia. These nocturnal (most active at night) animals spend 18 to 20 hours each day resting and sleeping. They are social animals. Koalas are not bears; their closest relative is the wombat. The genus and species of the koala is Phascolarctos cinereus. These herbivores (plant-eaters) eat eucalyptus leaves. Koalas have a keen sense of smell which they use to make sure the gum leaves are edible and not poisonous. They store food in cheek pouches. Human exploitation is the primary reason penguins are endangered. The decline of the Humboldt penguin began in the mid-19th century when the intensive activity of guano...

...The blobfish is endangered for many reasons and you may be one of them. The man reason is because of overfishing which is to deplete the fish (in a body of water) by too much fishing. Which has endangered and destroyed many other marine animals. Blobfish live where other tasty creatures do also so, fisherman catch blobfish with other creatures. But don’t worry blobfish aren’t edible. So don’t worry about your mom cooking fresh blobfish for dinner with a side of shrimp! Blobfish are usually caught in the bottom of fishing trawlers. When a fisherman catches the blobfish they usually don’t put them back. However, every time an animal goes extinct it forms a new hole in the web. Blobfish also eat whatever goes into their mouths, because they don’t have any muscles. Because of their lack of muscles, they cannot swim around and look for food. Instead, a piece of something may float...

...The slow but sure physiology of the animal is reflected in the slow but constant evolution of the turtle’s brain over the last 210 million years. Scientists compared the brain of the Proganochelys, the oldest turtle with a real shell, and modern turtles by using computed tomography scanning on two fossil skulls. Very simple brain structure Dr. Stephan Lautenschlager, the lead author from the University of Birmingham’s School of Geography, Earth and Environment, said that the results of the scan showed the animal had a very simple brain structure. The turtle’s vision and hearing were likely not very good, while its sense of smell was developed moderately. Over the course of its evolution,...

...and biologic diversity of animal and plant species. Threatened, endangered, and extinct species are only some factors that may influence biodiversity. Any given species has to meet a certain criteria to suit the previously named terms. Conservation biologists are concerned with numerous species because of said species’ influence on the interrelation within their ecosystems, and the interruption of such ecosystem when the numbers of a certain species are drastically decreasing. Conservation biology is concerned with the maintenance of species, their genetic variation, ecosystems, and communities within such ecosystems. Biodiversity includes “The variety of life and its processes, including the variety of living organisms, the genetic difference among them, and the communities and ecosystem in which they occur” (U.S. Fish & Wildlife Service, 2004, p. 1). Even though the term “species” is complex, and some definitions may differ slightly from others “A species is often defined as a group of individuals that actually or potentially interbreed in nature” (Berkley University, n.d., p. 1). Therefore, a species is defined as the greatest gene pool that can exist as long as natural conditions are given. A species is considered threatened if such species “is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range” (U.S. Fish & Wildlife Service, 2004, p. 2). The definition of an endangered species is closely related...

...forests were destroyed by lava and mudflow, producers were completely destroyed and died out. This caused a disruption in the food cycle because then, consumers such as deer had less food supply causing them to starve and die. After a while, the decomposers begin to kick start the cycle for new life, bringing back order. Exercise #2- Discuss any two plant species and any two animal species that are affecting the Everglades. What are the challenges facing the native species and how are they adapting to the changing environment? List 3 references. Plants – Australian pine- This plant was brought over to the Everglades and used for landscaping purposes from South pacific Islands and Australia. The tree’s roots disrupt the nesting of the native creatures such as the American crocs and turtles. Brazilian pepper plant- This pepper tree was brought over from Brazil to market the peppers. As birds ate the seeds, they begin to spread them from their feces. As these trees begin to spread throughout the Everglade, its dense structure allowed it to form concentrated thickets displacing native vegetation. Animals – Green iguana- These iguanas were imported from Central America as pets. As they begin to get to big, the owners started to let them free. They live off of the native vegetation and repopulate quickly. They also began to eat the native tree snails which are threatened and rare. Burmese python- Also brought over as pets from Southeast Asia, these pythons have...

...First, I would like to talk about the Tasmanian Devil. Here are a few facts about the food that the Tasmanian Devil consumes. They are known to attack poultry and dead animal carcasses. Where the poultry or prey lives they want to live near it or them. When they hunt at night, they make loud growling noises to threaten their prey. When they chew, they can crush almost any bones with just their teeth. Also, their fur camouflages them in the dark whenever they hunt for food. It usually only moves away from it’s home three miles looking for food. The joeys attached to the mother’s teats leave after three months. They enjoy eating dead farm animals and their diets are mainly carnivorous. They can almost eat anything that looks desirable to them....

...Taz and Ant; One Endangered, One Invasive Taylor Drake Biology 106A, Fall 2012 In a world dominated by humans there are many things that also inhabit Earth, one of those being animals. Sometimes these animals can thrive in certain or multiple geographical areas while others, due to humans, may fail to adapt and survive. An invasive species is one that has a native geographical range but then somehow gets transferred to a new geographical range where it possibly can thrive and cause problems such as the Red Imported Fire Ant. On the other hand, there are some species of animals that are endangered and on the brink of extinction like the Tasmanian devil. With the encroachment of humans on the animal’s environment, they have hindered their ability to thrive forcing them to become endangered. Humans influence on the ecosystem, animals have to adapt like the Red Fire Ant or be forced to near or possible extinction like the Tasmanian devil. 1 The Tasmanian devil (Figure 1), Sarcophilus harrisii, is the largest carnivorous marsupial of the family Dasyuridae found on the Australian island of Tasmania (Figure 2) (Tasmanian devil). The devil is normally black with a white patch around its neck and generally about the size of a small dog weighing between fifteen and twenty Figure 1.
