In my term paper I would like to talk about the American Bullfrog population in the Great Lakes region, its evolutionary history, its place in the phylogenetic tree, ancestors (Gerobatrachus Hottoni, proto frogs), and nearest relatives (salamanders and caecilians), how the species has spread around the world, how it interacts with its environment, what role it plays in the ecosystem, its role as an invasive species and the threats that it poses as such, and finally argue that the main concern about the species should be safe ways to keep populations under control without harming the species or ecosystems around it. I chose to research and write about the Great-Lakes-area American Bullfrog because I began volunteering with a frog call monitoring program at the Lincoln Park Conservancy, but here is a bit of my preliminary research that may interest you as well:

Its native range extends from the central and eastern United States up into Southern Canada. But the frogs are now found from Nova Scotia to Central Florida, from the East coast of the U.S. to Wisconsin, across the Great Plains to the Rockies, as far west as California and Mexico, and even places like Hawaii, the Caribbean, South America, Europe and Asia. It appears the species was introduced from its original habitat in North America in the early 1900s in Colorado and California and the introduction appears to have been accidental. Evidence suggests the frogs could have been introduced through trout streams and lakes during the Colorado Divisions of Wildlife fish stocking operations in the early 1900s, as bullfrogs have been known to invade fish hatchery ponds and leave their larvae to be stocked into ponds along with the
The professor points out that young cane toads and their eggs live in rivers and streams and water flow young toads from one side of the river to the other side. Therefore, the professor adds that even if few of the cane toads could
Tȟatȟáŋka Íyotake, or Sitting Bull, the notable Hunkpapa Lakota Sioux holy man with audacity, was a Native American who endured the years of resistance to United States government policies. The result of this phenomenon was the overpowering conquer of United States army officer George A. Custer. This also included his 7th Calvary at Little Big Horn. During his strife for survival on the North American Great Plains, Sitting Bull was known to amalgamate with other tribes, such as the Sioux. From all of his indispensable moments and redundant contributions, Sitting Bull will emphatically be remembered today.
The golden frog was usually seen throughout El Valle and nearby towns the locals begin to notice that they no longer was seeing the frogs around and throughout the towns nearby. The golden frog in bright in color and can blend into the back ground of the rainforest Kolbert describes “ the panama golden frogs are toxic it's been calculated that the poison contained in the skin of just one animal could kill a thousand average size mice hence the do color makes them stand out against the forest floor.(Kolbert p19). Kolbert States Millions of frogs or being found belly up throughout Panama researchers from all over did not have a direct conclusion to why the golden frog were dying all over. Biologist grew alarmed about this species and why the golden frogs has vanished from the
The Cane toad also referred to as Rhinella Mirina is an invasive toad species that is native to subtropic South America. Although they are native to subtropical rain forests, they show a preference for areas modified by humans such as gardens and drainage ditches. These toads reproduce very rapidly and have very few predators due to the toxin present on their skin and parotoid glands behind their eyes. These toads are considered pests due to the havoc they wreck on the other species within the ecosystem.
It is typically 1.5 to 5 inches in length. This is an issue because it is not native to North America. The treefrogs were brought to North America by ships travelling from the Caribbean. Since there are no predators to the animal the population has been able to spread all the up to North Florida and the Jacksonville region. People have reported that when the Cuban Tree Frogs appear on their property the population of native frogs, toads, lizards, spiders, and insects have severely dropped.
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.
In the recent years, there has been an increase of invasive species in Florida such as the Burmese phyton. These reptiles are initially from Southeast Asia but due to the irresponsibility of some pet owners, they have started to invade Florida specifically in the Everglades. So far, an alarming amount counting in the hundreds have been captured in the Everglades National Park, showing how important it is to keep their population under control and from wreaking havoc. Known for consuming birds and small mammals, they show an immense effect on the local ecosystem. Authorities have hired hunters and even started annual manhunt events for these pests.
Bullfrogs Bullfrogs have been invading anywhere they can for many years. They have managed to make their way all the way to Arizona. They have also come to many harmful terms to keep alive. There have been many ways that scientists have tried to remove bullfrogs from informants in Arizona and have mostly failed that is why I believe we should I think we should do more to stop their invasion from further worsening. Humans should not allow bullfrogs to spread or reproduce because it is invasive and destructive to the environment.
There are bull riding school all around the United States and other countries even. There are bull riding schools all across america but there is one in texas that kind of has me hooked and is outstanding helping kids and adults learn how to bull ride and can even help them go pro. Fort Worth, Texas has a bull riding school there that taught the best pbr riders throughout the world and they have a great program that not only teaches you how to ride bulls but how to conquer them also, and this school even before they went pro helped out even the best rider’s get to the pbr. There are other facilities around the world. Nashville, Tennessee has a great riding program for all ages that want to bull ride, they also have bronc riding which is almost
Some similarities between Andrew Jackson and the pup described in S. J. Krause’s article are: how the pup looks similar to Andrew Jackson, how the pup can fight when he needs to, and how the pup was all about himself until something does not goes his way. In the article, the author describes how Andrew Jackson and the pup look similar by looking all innocent but ornery. The pup tries to look innocent so that other pups will think he is easy to beat. Andrew Jackson tries to look innocent to the public so that they will like him.
There is a negative stigma which follows certain breeds of dogs. Pit bulls for instance, are considered as a dangerous breed. In some cities such as Miami, they are banned and in many shelters, pit bull breeds are amongst the first to get euthanized. What people fail to realize is that dogs’ temperament is indicative of their owner and the care and training they are given.
She then proceeds to introduce the idea of a global mass extinction and explains that in all of history, such an event has only occurred five times. The rate of the frogs’ disappearances, however, is alarmingly similar to a mass extinction and Kolbert presents “the notion that a sixth such event would be taking place right now” (Kolbert 11). Rather than simply telling us that a global mass extinction is occurring, Kolbert uses the idea of a mass amphibian extinction in the Americas to introduce it. This makes the audience more likely to agree with Kolbert as the story she told seems to be proof of what she is claiming. In addition, the example of the frogs shows the audience that the sixth extinction is a real and present

Attention Getter] Did you know that according to the National Park Service, in the mid 1970s the Greater Yellowstone region only inhabited about 136 grizzly bears (United States)? A. The Federal Government quickly protected them under the Endangered Species Act, and that is still in force today.
One of the best days of my life was when we went deer hunting in South Dakota with my dad, brother, uncle and two cousins, but before I tell you about my trip let me tell you how it started. We left early in the morning to head to South Dakota where my cousin Jacob, who had just got a job as Game warden in Custer State Park, was taking us deer hunting. We got as far as Fargo, North Dakota when my cousin Keith asked my dad where our license were. Then to our surprise we forgot them back at home. We were lucky enough to have my two aunts and mom bring us the license because they were going to Fargo that day anyways for a girls shopping day.
