Whistling Tree Frog Research Paper

The Northern Correboree Frog is an endangered species that is restricted to montane, subalpine woodlands, grassland and heathland 1,000 metres above sea level. The estimated amount of Northern Correboree Frogs is 1000-5000. One of the reasons why the Northern Correboree Frog is endangered is because of climate change. Climate change affects the Northern Correboree Frog because it was predicted that its population would decrease in winter and spring precipitation because, this would make one of the popular breeding habitats (edges of bog pools) very saturated and dry, which makes it hard for the frogs to breed.

The importance of El Valle De Anton spurred the movement to create systems to preserve frogs worldwide. In Panama a town name El Valle De Anton once deeply respected their golden tree frogs, and ironically they were not disturb when the frogs started disappearing. When the corpses started to pile up, the scientific community began to become concerned and began an effort to preserve the golden frog species and what they found was that frogs from around the world had been plagued by Batrachochytrium dendrobatidis-batrachos (or “Bd” for short). This plague is very hard to stop, as we cannot purge the entire planet of the disease, and the plague spreads incredibly quickly.

The mountain yellow-legged frog is declining due to the introduction of trout, contaminants, increased levels of ultraviolet radiation, and the fungal disease, chytridiomycosis. David Bradford, one of the first witnesses to the decline in the late seventies, noticed the species dropping because of the red-leg disease. Because this is a secondary infection, the frog’s immune system was weakened before the disease became existent. The chytrid fungus was first cited in the Sierra Nevada in 2001, brought here from African clawed frogs, but studies have suggested that the disease has been evident since the mid-‘70s. Nearly three decades later, the mountain yellow-legged frog is still declining. Currently, with a ninety-eight percent decline, there

Chapter One details the ancestry of frogs and examines the timeline of amphibians on Earth, as well as the increase in frog extinction rate. Kolbert argues that the observed extinction rates which are exceeding expected background extinction rates suggest that catastrophe is ahead for Earth. Humans are key to the extinction of Panamanian frogs due to their spreading of the Chtrid fungus, which is not native to Panama. Thus, Kolbert sees humans

The cane toad, also known as rhinella marina, got its bad reputation soon after being released into the Australian ecosystem in 1935 with the expectation that it would control the destructive cane beetle population. However, instead of controlling pests, the cane toad became a pest of its own. About 3,000 cane toads were released in the sugarcane plantations of north Queensland in 1935. There are now more than a million cane toads and their still expanding over an area of thousands of square kilometres in northeastern Australia. They are large, amphibians with dry, warty skin, and are native to the southern United States, Central America, and tropical South America. Their numbers are controllable in their normal range, but they have boomed

Nowhere near a plethora of evolution has adorned the history of the poison dart frog, yet the evolutionary history will fascinate one. The toxic amphibians are beautifully constructed creatures, their magnificent colors, the highly poisonous oil on their skin, and their hasty, yet graceful, movements. But where did it all begin? It began with the ancestor of the poison dart frog, the primitive frogamander.

Pacific Coast of Colombia is the main place where you would see the poisonous frog. Many tropical rain forests in this area are disappearing because of the farmlands that are being produced, causing Golden Poison Dart Frogs to be designated as an endangered species. The lowland rain forests, that contain steep rocky terrains, is a main habitat for the frog. The elevation is 100ft to 200ft, with the temperature

In the beginning of the book “The Sixth Extinction” by Elizabeth Kolbert, she mentions a species of a frog that is going extinct because of a fungus that has been brought over by humans and has been spread around by water. It is attention-grabbing for the majority of people to find out what is happening to these frogs and for people who share an interest with frogs it is concerning. Either its interesting or concerning it is important to know how these fogs are dying if humans seem to not be bringing harm to them on purpose, most would assume the fungus occurred naturally. However, in the book Kolbert mentions “Without being loaded by someone onto a boat or a plane, it would have been impossible for a frog carrying Bd to get from Africa to Australia or from North America to Europe” (Kolbert 18). Since Humans have altered the way we live and it is constantly changing it was only a matter

Researchers are currently trying to gain knowledge on the extent of the problem; how the parasite works, what species can be infected, and once infected, what species experience the least amount of symptoms. They believe that by infecting native tree frogs with this parasite, they may be able to increase the amount of parasites while decreasing the amount of toads. L.Pizzatto and R. Shine (2011) had three assumptions. “(1) The parasite has no detrimental effect on the frogs; (2) the frogs are capable of maintaining a lungworm infection long term; and (3) infective larvae passed in the frog’s faeces are capable of infecting toads and reducing their viability.” (p.546)

Poison dart frogs as stated by Patocka, Wulff and Palomeque, (1999) are members of the Dendrobatidae family, which secrete poisons from glands in their skin. According to Patocka, Wulff and Palomeque, (1999) there are over 150 species of poison frog already known.They further state that the family Dendrobatidae has eight genera which includeDendrobates, Phyllobates, Aromobates, Epidobates, Minyobates, Manophryne, Nephelobates and

Source 2 discusses, these toads were brought to Australia from Hawaii to try and lower the cane beetle population. However, these toads had no effect on these creatures, but they do have some physical attributes which are deadly to other native creatures of Australia. These toads are toxic, predators who are native to Australia do not have any immunization to this poison (Source 2). The cane toads’ poisonous abilities allow it to protect itself from predators it may have in Australia. These abilities also allow the toads to capture their prey with more ease because their prey are not immune to their poison. Source 2 states, cane toads “kill native predators such as the quoll, a cat-like marsupial”. These toads feed on native animals of Australia, whether they are eating the right animals is another debate. Since these animals feed on native predators of Australia, there is not a shortage of them in their habitat. The cane toad can easily find food in Australia, therefore they can easily stay healthy and survive in Australia. Therefore, their reproduction rate is very high. According to Source 2, the cane toad population has reached beyond two hundred million. Their high reproduction rate shows the cane toads have not struggled to mate whilst living in the conditions of Australia. Therefore, since cane toads have easily been able to adapt to life in Australia, they have been able to continuously reproduce, generation after generation. Even though cane toads are not native to Australia, they have not struggled to adapt to life

Principal Huggins goes to the Loud House for frog inspection. When he checks Lynn and Lucy’s room, bats fly out, frightening him. He’s sure there are no frogs in there.

Overall for this change project, we have learned that the population of frogs has been decreasing all over the world. There are many factors that decrease their population like agriculture, invasive species, and the population of humans. Specifically, in California, only 40% of the historical sites in the Northwest area have Foothill Yellow-Legged Frogs, and this has the highest percentage out of all of California. These frogs are indicators for the environment, meaning they can determine if the area around them has changed dramatically due to their permeable skin. For our service project, we removed invasive plants like the Himalayan Blackberries and dug creek beds for the frogs. From this, we were able to improve the levelness of the area

The whites tree frog are more resistant to diseases than other pet frogs, making them a great choice for someone looking for a "long term" pet. They also don't mind being handled occasionally.

Frogs, toads, caecilians, and salamanders are the members of the class Amphibian (amphi- meaning “on both sides” and bios- meaning “life”). These members always require water for reproduction. Most Amphibians undergo metamorphosis, which is a usually degenerative pathological change in the structure of a particular body tissue. And, in the case of Amphibians, it is the changing of a tadpole into
