The Impact Of Cane Toads On The Australian Environment

It is often difficult to convince people that there is an issue present which requires their attention. Infinitely more difficult is convincing them that they are to blame for the issue or problem at hand. Nevertheless, this was the task that faced Elizabth Kolbert as she wrote The Sixth Extinction. In cases like this, writers often have to use various rhetorical strategies and techniques just to reach their audience. Kolbert’s The Sixth Extinction is a perfect example of just how writers use powerful tools to connect with their readers. In The Sixth Extinction Kolbert’s tool of choice was narration. In essence, Kolbert uses narration to engage and connect with her audience and better convey her arguments and ideas in a manner that is easily understood.

In this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05). This indicates that we are unable to show a statistical difference between Isopods preferring the syrup environment over the water environment.

Burmese pythons have a large number of sharp, strong, curved teeth. They have long bodies that can strangle their prey. Burmese pythons have invaded Florida’s Everglades. These snakes are very vicious, and they have no known predators. These pythons will tear their way through the Everglades. They don’t belong in Florida, and they are taking over the Everglades. The presence of the invasive Burmese pythons, has a negative impact on the population of other animals in the Everglades.

Invasive species are “species that is non-native to the ecosystem whose introduction is likely to cause economic and environmental harm”. A example of Invasive species would be the Zebra Mussel. Zebra Mussels or also known as Dreissena polymorpha is a small freshwater mussel. The Zebra Mussels can live up to three-nine years which can grow up to 2 inches. These mussels attach to hard surfaces such as rocks or boats. They were first introduced to the Great lakes in 1988 but were originally from Russian and Ukraine lakes. The Zebra Mussels were first found in Lake St. Claire (one of the 5 great lakes) which within one year they rapidly spread to almost all of the Great Lakes except Lake Superior. This is because Lake Superior is not the ideal

Burmese Pythons are a species of snakes that originate from Southeast Asia. They are an invasive species, and invade in places such as the Florida Everglades. Many people had them as pets, but when they became too big for homeowners they decided to set them free into the Everglades. As snakes can eat many large and small animals, they have enough to food to survive. But as they are not native to the Florida Everglades they then have no natural predators, so they reproduce, and each egg has about 10 snakes in them, so you can see why that may be a problem. As many people may think the snakes are a threat they may also be scared and may not want to help, but there are people that do want to help and need to find a solution to the problem. For example

In our experiment, we examined the behavior of isopods by conducting the experiment based on our hypothesis: “If ten isopods are put into the test chamber, 5 in sand and 5 in soil, which environment will the pillbug prefer.” We hypothesized that the isopods would favor the soil more than the sand because pillbugs are typically found in soil and not in sand. Pillbugs are favored in soil because the natural role of a pillbug is to eat dead and decaying things but, in sand there are no nutrients available for pillbugs. Pill bugs are mostly found in moist environments, due to having gills, gills only function when they are wet so pill bugs will inhabit places in which air holds a lot of water

Under dark waters lurks a 20 foot monster ready to attack. This monster is the Burmese python and they are taking over the Everglades. Before you know it, they might end up in your very own backyard. There are many ways the presence of the Burmese pythons are changing the Everglades. These snakes have caused many problems for the animals and ecosystem in south Florida. Although many solutions have been tried, nothing so far has worked.

There is a terrible monster roaming the Everglades. This creature is capable of eating anything in its path. There are many ways, how is the presence of Burmese Pythons are changing the Everglades.These snakes have caused many problems. Although many solutions have been tried, nothing so far has worked.

Invasive species are a big problem to the United States ,because they can cause billions of dollars in damage. In this paper it will reveal some of the most known invasive species in the Florida everglades. The different Invasive species that will be discussed are the Giant African Snail, the Brazilian Pepper Tree, and the Cuban Treefrog.

There are many major concerns with this snake. First, they grow rapidly to about 20 feet and 200 pounds. Secondly, they can live in many kinds of habitats. Thirdly, they live in trees, which make them a threat to birds. Fourthly, they are suitable to live in urban areas. Fifth, they are difficult to detect, which makes it harder for them to be detected. Sixth, they mature rapidly, and produce many offspring. Seventh, they can get to high population densities, which is why the environment is at great risk. Lastly, they serve as hosts for parasites and diseases (Florida 's Python Problem: Snakes Reshape the Everglades). All of these issues are possibilities. The environment though as already been affected. For example, the wood-rat, which

Around the world, poison frog populations have been declining due to unknown reasons. Two experiments were conducted promptly in order to find the cause of the disappearances. One hypothesis suggested that the poison frogs are in a decline because of an infectious fungus called chytrid fungus. On the contrary, another hypothesis alludes to the idea that decreasing leaf litter is causing the widespread decline. Although it seems that there are multiple reasons for the decline, it is unquestionable that, according to the data from the experiments, that leaf litter is one of the main components of the decreasing population of poison frogs, having multiple replicates of data is important in finding the answer to the decline, and that there is much more to investigate about this problem.

The reading states that several measures have been proposed to stop the spread of the cane toad in Australia and provides three reasons of support. However, the professor states that the measures in the reading passage are unsuccessful and cause unwanted damage and refutes each of the authors ' reasons.

Iowa is filled with astounding places such as the Mississippi river, the Wildlife Refugee and the Indian creek. All of these natural resources and wildlife are slowly getting turned into farming and agriculture. Although, both are extremely beneficial and important to our society, there needs to be a balance between the too. The organization that is trying to preserve this balance between wildlife and agriculture is the Iowa Cooperative Fish and Wildlife Unit. The organization goes along with Iowa States mission and vision because they are trying to make the world a better place and they are putting technology to work. The organization was created at Iowa State University but its ideas spread throughout the state and the nation. The goals

It is well known that eutrophication occurs when excess nutrients are added to a body of water and primary productivity is increased. However, the scientific paper, Aquatic eutrophication promotes pathogenic infection in amphibians, puts a direct focus on a specific parasite, Ribeiroia ondatra, and seeks to give evidence that the onset of eutrophication is the driving factor allowing the parasite to disrupt amphibian development. The authors set-out with the goal to provide evidence that eutrophication leads to an increase in the number of snails as intermediate hosts for the parasite, while also increasing the snail size and reducing snail mortality; providing more candidates to pass the parasite onto amphibians to inhibit their development. This research, as stated in the paper, looks to identify eutrophication as the factor promoting this pathogenic infection in the amphibians. Although some have tried to pinpoint this already, no evidence prior had been provided to

While researching about how pollution affects sea turtles, we faced some issues on finding different types of pollution. As most people know, the plastic waste that is being dumped into the oceans and onto the beaches is becoming a main food source for sea turtles. When sea turtles see this trash, they consume the plastic causing death or severe sickness which has caused this species to become endangered. They also get tangled with the plastic in the ocean restricting them from normal movement and function. During our research, we found that there are more types of pollution affecting sea turtles than just plastic waste in the ocean. For example, the nitrogen runoff and arginine build-up settling in the sea turtle’s habitats is causing tumors
