Mountain Yellow-Legged Frog Research Paper

Most amphibians are critically endangered and this is explained by the spread of chytrid, habitat loss, and overexploitation. Researchers are saying chytrid is the explanation for the enigmatic decline. This fungal disease affects almost all amphibians by attacking their skin, eventually giving them a heart attack and killing them. Habitat loss, by climate change or deforestation, is also extremely dangerous as many amphibians only have a few places they can survive (i.e. spotted frog only has 3 places to thrive). As well, climate change can change the amphibian’s environment so great that the species can no longer survive in their habitats.

    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.

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)

The Northern Correboree Frogs were quite abundant and plentiful in the Fiery Range. Only one population, Ginni Flats ( a sub-alpine area), was monitored annually, and in these inspections, the scientists and people monitoring these sites found out the numbers of frogs had substantially dropped and has been low ever since. Despite these statistics, with my gathered information I assume that in the past 200 years till now, had a huge difference in population, meaning that the Northern Correboree Frogs are

In the past we have tried to contain these Cane Toads by setting up traps in the dry-seson however many blue tongue lizard got caught in them. They also tried to set up fences around areas that only have 1 or 2 freshwater lakes in them so that the babies cannot walk away from the area. This worked but we cannot simply fence up all the water sources in the top half of Australia. But I think we should create a poison on the cane toads. Because the other thing that eats Cane Toads is Cane Toads; therefore if we create a poisson on them we are able to get rid of many toads. The first step in creating this plan would be to make the poission. Secondly we would give the poison in a syringe to every homeowner in Northern Queensland so that they can

The issue I will be raising is one that might not be familiar to all who reside in California and that is primarily focused around the fragmentation and overall mutilation of areas that keep and protect the species Rana Draytonii, otherwise known as the California Red-legged Frog. One of the reasons I raise this issue, is because most importantly “these frogs were named the official state amphibian of California via AB 2364” (Patrick McGreevy.). An even greater reason to discuss this dilemma is because they are limited in their size around the Southernmost California residences, whereas they had previously occupied approximately “70% of its former habitat” according to environmentalists (Campbell.). My goal is to highlight their ecological value to the state and how the California red-legged frog’s value is more significant than the fragmentation and intrusion taking place. These red-legged frogs are currently listed as endangered, but they are vulnerable to human intrusion by means of erecting buildings, projects for road construction, introduction of a non-native species along with habitat fragmentation in areas near where they might usually reside such as near the south Mendocino County and along southern California with populations extending to the Santa Rosa Plateau (Hammerson, Geoffrey). The California red-legged frog has an intrinsic link to

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

Have you ever wondered if there was an animal that was clear and you could see inside it and out the other side? Well you can my essay will be about one of the coolest the 1 the only Glass Frog!

Anaxyrus terrestris or more commonly known as southern toads are a nocturnal toad species common to southeastern areas ranging from Virginia to Florida and eastern Louisiana (Partymiller, L.). St. Andrews University which is located in Laurinburg, North Carolina, is the home of a carolina bay which is the perfect habitat for southern toads. This bay, in turn provides for a large abundance of southern toads.

One animal that prepares for the arrival of winter is the Rana Sylvatica, it is a species of wood frog’s that freezes it self through winter and then comes back to life. The tiny amphibians can survive for weeks with an incredible two-thirds of their body water completely frozen to the point where they are essentially solid frog sicles . Even more incredible is the fact that the wood frogs stop breathing and their hearts stop beating entirely for days to weeks at a time. In fact, during its period of frozen winter hibernation, the frogs physical processes from metabolic activity to waste production grind to a near halt. What’s more the frogs are likely to endure multiple freeze or thaw episodes over the course of a winter.The frogs have

When attending this lecture I did not know what to expect because I had never been to one. Being an elementary education major, biology is not a strong subject. I was never very good at it in high school and I still struggle with it today. The man speaking about the frogs was very informative I actually learned a few things about frogs. When he began talking about complex phenotypes, phylogenomics, and neurophysiology I got a little lost so, I researched a little bit more about other things I understood.

There are two main species of Horned Frog, the Argentine horned frog and the Cranwells horned frog, both of which are found in the wetland areas of Argentina on the tip of South America.

While in the Frog’s classroom, during my observations, I noticed that sharing toys among the children has been a popular conflict. During one incident, four kids were playing with magnets and Noah tried joining in but there were too many children at the table. Noah tried to grab some magnets that were already being used by another child. Noah then became angry and expressed his anger by head butting the child who was using the magnets. One of the teachers then began to notice what was going on. The teacher then told Noah that head butting was not okay and that he needs to wait his turn or go find a different toy to play with. Noah then walked away with a strong attitude. The teacher asked if he needed to take a break and sit down on his own.

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

Frogs’ distribution ranges from the tropic to subarctic regions, but most are found in tropical rainforests except Antarctica. They are found in almost every habitation that provides access to water. The world consists of more than 5 200 species of frogs and some still are not yet found (Tyler, Wassersug, and Smith). Some of the countries with the most frog species include Brazil, Colombia, India, Cameroon, Madagascar, among others (“Frogs”). In the U.S. we have 90 frog and toad species. However, until recently, whether one lived in a city, a rural, or anywhere in the world, chances were high that an individual was not far away from seeing a frog or other amphibians such as toads, salamanders, and caecilian. What has changed? In the U.S., the reduction of frogs and other amphibians is serious in California, the Rocky Mountains, the Southwest, and Puerto Rico. Other continents such as Australia,
