    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 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.

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

There is a deadly fungus called Batrachochytrium dendrobatidis, Bd for short, that has been wiping out populations of frogs all across the world. Bd has caused dozens of extensions over the past four decades and leaving behind very few survivors. Also in the 1980s the frogs faced a similar problem with this chyrid fungus that wiped out four frog species. However, there are two frogs, the whistling tree frogs and the alpine tree frog, that are doing better than scientists predicted.

In their movements, northern leopard frogs can encounter native grass prairie as well as crop fields and grazed pastures that potentially can act as barriers to their movements. Since grassland prairie and wetlands in the PPR have been greatly reduced, the wetlands that are highly depended on by the northern leopard frog to complete its’ life cycle in the prairie pothole region have become separated by greater distances. Depending on the cover type through which a frog must move, it can become exposed to the sun, wind, and other environmental factors for longer periods of time that, in turn, could cause them to lose water faster than if moving through a more naturally vegetated area. In addition, they may become more visible to predators.

Animals of all kind are going extinct and dieing out. “One May 19, 2010, at Joint Base Balad, north of Baghdad, Iraq someone brought U.S service member Jonathan Trouern-Trend a frog in a plastic bottle.” Trouern-Trend was a animal guy and interested in the conservation of animals. Before releasing the frog Trouern-Trend took a picture of the frog snd sent it to iNaturalist, which connects people to sightings of animals, plants, and other organisms online. Users of iNaturalist told Trouern-Trend he found a lemon-yellow tree frog the app informed him that scientists had not recorded that type of frog outside of Kurdistan. Since Trouern-Trend sent a picture to iNaturalist the species known range has expanded. This is some of the good that can

The Azuay stub foot toad, native to South America and thought to be extinct, was recently found to be extant in Ecuadorian Mountain Forests. The species, which was once predicted to be abundant, was thought to have been extinguished mainly in part by the chytid fungus, a fungus which is decreasing the population of many other amphibian species as well. According to the information provided by the article, the Azuay is not the first to be re-found after thought extinction. Scientists are still unsure about the species’ survival however, in which conservation methods will be needed.

What was the reason you chose to research about this species (topic)? The reason I chose to research about this species was because I thought it was a somewhat rare species that is not really heard from in public or rather often and I feel like I can teach someone about this species and at the same time learn myself further more about this species while I do this research or project as I would call it. A problem that I would say this species faces is that it is becoming extinct because of the small amount of capacity that shelters can only hold for frogs therefore, they are becoming extinct because there is no room for these amphibians to survive in and another problem I would say that that this specie faces is that there isn’t much information as there are to other species

This book is considered a valid source, as a contributing author to the chapter was Hines, who was also referenced in the trusted IUCN Red List. Furthermore, the National Heritage Trust Australia, a non-government organisation that conserves natural heritage and the Department of Environment and Heritage, a government body responsible for the protection and conservation of the environment are affiliated with the publication. The book’s extensive reference list includes many peer-reviewed journals, surveys and other citable publications, and has itself also been cited as a source for many trusted publications regarding the Wallum Sedge Frog. The publication gives information regarding the distribution, biology, threats and conservation status of the Wallum Sedge Frog. This information is important as it provides knowledge of the specie of

More than 100 species exist in three genera within this family of tree frogs; Centrolene, Hyalinobatrachium, and Cochranella. (Cisneos-Heredia 2007) These animals are extremely small in size and make them very hard to find and study. Because of the difficulty in finding these frogs, new species are regularly being described, and the family is growing. Distribution is limited to the humid Neotropics, with the greatest diversity in the Andes, Costa Rica, Panama, and Ecuador. (Cisneros-Heredia and McDiarmid, 2005; Guyer and Donelly, 2005) They live in wet tropical forests in high trees overhanging rivers and streams. These frogs begin their lives in a terrestrial habitat, as an embryo within an egg clutch upon a leaf. As the tadpoles hatch, they drop into the water below, where they begin metamorphosis. Once they have reached adulthood, they return to the terrestrial habitat alongside the stream. (Beletsky,

The text states that, farmers are pouring plant poison in the frogs invironment. Unfortunatly, it's toxic for the frogs too. The poison kills the frogs, and they are getting close to extinction. Frogs are very special types of creatures, leading to extiction would make a various number of

Our planet is currently suffering its Sixth Great Extinction, a time in which a various species of organisms are disappearing at an unprecedented rate (Collins and Crump xv). The most rapidly disappearing groups of organisms are amphibians, and over 200 of these species have been brought to extinction since the year of 1970 (Save the Frogs). One of the largest causes of their rapid declines is the spread of the lethal disease chytridiomycosis, a fungal disease largely spread by humans (Whittaker and Vredenburg). Frogs and other amphibians are dying from this chytridiomycosis because of our selfishly taking them from the wild to an assortment of distant locations simply for the pet trade, food trade, and dissections, which are all unnecessary to economies (Kriger and Hero 1). In order to conserve the over 2000 amphibian species in danger, the ecosystems they support, and humans as well, we must prevent the lethal

One reason, frog’s habitat are being destroyed by humans. In text, it says, “Amphibians like these fishless habitats, but humans drain them in order to create land for housing, parking lots and shopping malls.” It shows that people don’t understand that they are hurting frogs by destroying many parts of the frog’s habitat.

Tropical rainforest contains the major biodiversity of any biome. Global warming scenario is affecting the diversity of the population of the tree frog population. Due to climate changes, the frog is unable to adjust to new climate which resumes in population decrease.
