Essay On Amphibian Species

Florida has more introduced species of reptiles and amphibians in the wild than anywhere else in the world, causing the native populations to become unbalanced (University of Florida, 2012).

    Recently, an invasive and lilliputian frog has had a detrimental effect on the Hawaiian environment. Originally from Puerto Rico, the amphibian arrived in Hawaii and spread like a plague. Such a small frog cannot have that big of an impact, right? Wrong. The Coqui frog is a damaging invasive species of the Hawaiian islands due to its lack of natural predators and adaptability, dangerous eating habits, and its easy distribution among the state.

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 toads are known for being in the east coast region of America. These places are known for their loose grainy soil the toads can dig in. Eastern Spadefoot toads like to live in semi-arid places with sandy soil for the toads to dig in using its spades. The toads do so to keep themselves from drying out.

TYPHOID MARY IN THE FROGPOND: CAN WE USE NATIVE FROGS TO DISSEMINATE A LUNGWORM BIOCONTROL FOR INVASIVE CAN TOADS?

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 article explains that several measures were proposed to reduce the cane toad population, and provides three reasons of support. However, the professor explains that it would not be easy to get rid off the cane toad population and several measures taken, but that were unsuccessful, and refutes each of the author’s reasons.

Known in the scientific community as Bufo marinus, cane toads were introduced to Australia in the mid-1900’s t rate from their native home of South America. Sugarcane crops were at risk of destruction from the infestation of beetles, and these species were brought in to help counter the negative effect that the beetles were having on farms. These amphibians have the ability to grow up to 4.4 pounds, and were soon doing more harm than good. Not only were the cane toads eating the beetles that they were meant to, but they also started including native insect-eaters in their diets (Roach). This new addition to their food source helped the toads to thrive and expand their habitat region.

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

Many sources say that the initial spread of this invasive species began at the end of the 1800's when bullfrogs were shipped to California to fill hungry loggers appetite for frog legs. The frogs competed with the other native species with the supply of natural resources while also consuming and exploiting the native amphibian species as well. Worldwide Rana catesbeiana has driven over one-hundred native species of frogs to extinction (Save The Frogs! et al. 2013). This is a huge impact on amphibian wildlife worldwide because there are about 4,800 species of frogs. Over the past hundred years the bullfrog has wiped out over 2% of the world's species of frogs. Studies have shown one of the reasons bullfrogs will cripple Arizonian ecosystems and the native amphibian species directly is because a female bullfrog’s physiology

They were brought in to help cut down the beetle population that was destroying the sugar cane in the area. While the toads were not useful in controlling the beetles, they were great at reproducing and taking over the area. When the cane toads were first introduced to Australia, they numbered around 3,000. Now there are more than 200 million of those toads hopping around, and they reside in 460,000 square miles of northeastern Australia territory. (BBC 2007). Scientists did not expect the cane toad to be able to live and multiply this well in Australia because the climate and ecology is not similar to Central and South America where the toads came from. Unfortunately, these toads have been able to adapt to the conditions in Australia and are thriving in the urban areas and may become prevalent in some of the major

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

The successful application of these rules does not depend only on the effort of an individual country, but also on the effort of surrounding countries. European Union has created EU Regulation on the prevention and management of invasive alien species in 2014, based on prevention, early detection, eradication, and management. Nevertheless, the past efforts to prevent and eradicate invasive species are not always productive. Within the European Union, UK is one of the countries which have made significant progress in the suppression of invasive species (Sambrook et al.

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

One example of an invasive species is Xenopus laevis, or the African clawed frog. These frogs carry a fungus called Batrachochytrium dendrobatidis. Chytrid fungus infects amphibians with chytridiomycosis by attacking the part of a frog’s skin that contains keratin. Frogs use their skin to
