Southern Corroboree Frog: Critically Endangered Species

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

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.

    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 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

Mark Twain use of American regionalism is very well done in both of his story’s and very important stated for the time. “Life on The Mississippi” and “the Notorious Jumping Frog of Calaveras County” By Mark Twain uses American regionalism in those two storys. Regionalism is terms refer to literary movement that flourished from the close of the Civil War. These terms are suppose to be all American, so The United States region. Mark Twain uses regionalism like “Life on the Mississippi” to make the events and themes of the narratives come to life to his readers.

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 study was done by Yale University and compared the proportions of frog sexes between 21 suburban ponds and isolated ponds in southwestern Connecticut. Its findings were published in the latest issue of the journal Proceedings of the National Academy of Sciences.

E. coqui reproduce in their native range year round, but during wet season is when breeding activity is concentrated. A female E. coqui lay 4-6 clutches of about 28 eggs each and about 16-41 clutches per year. The life cycle for the E. coqui start in a larval form that leads in a froglet within the egg. The next stage make this frog unique as it bypasses the tadpole stage in development, this is called free-living. The E. coqui internal fertilizes and, like other eleutherodactylids, the fertilized eggs never pass through a free-living larval (tadpole) stage. This particular stage is key to the success in the E. coqui survival in different habitats. It allows for the eggs to be

Literary Analysis In the folktale “The Celebrated Jumping Frog of Calaveras County” by Mark Twain writes about a nameless narrator in the 19th century that is in search for information about a man named leonidas W. Smiley; he goes in search for Simon Wheeler that knew Smiley in his boyhood. Then the narrator of the text transfers to Simon to tell the story about Smiley. The use of a frame narrative that Twain uses helps indicate a juxtaposition between the two narrators;using diction to emphasize the use of formal and informal.

The most effective way to prevent them from going through extinction is to restore and augment their environment. One of the greatest causes for their endangerment is the shrinking of the Houston toad’s habitat, either through fires or urbanization. Their main home, Bastrop State Park, was devastated by an immense fire, greatly decreasing their numbers. By fixing the burned forest, it gives the toad more land to live which will leave them in a vulnerable status. In other words, the more the habitat there is, the more Houston toads there will be. Many organizations such as the U.S Fish and Wildlife Services and Houston zoo have joined the fight to help these creatures.

Frog populations decreasing is a response of increasing levels of habitat loss, the conditions the frog population is put under is unfavorable because the frogs have semi permeable skin which allows pollutants go be absorbed by the body. Their natural habitats are quickly shrinking and pollutants from populated areas are seeping into what’s left of them. Scientists believe the leading factor of this population decrease is due to habitat loss to humans, as we expand our horizons so quickly, many ecosystems and populations are destroyed. As stated in the article, “some regions of the United States retain less than 20% of the wetland acreage they once had” (Volume 50). The importance of this quote is that it states the problem, less than 20% of their habitat still exists. This means there will be a struggle for resources amongst them and numbers will be forced to decline. As wetlands are drained, and rivers and streams are dammed up habitats change forcing the frogs to change as well. If the frogs can’t adapt to their habitat quickly they will die.

Some recommendations that we have to help the Foothill Yellow-Legged Frogs incorporates the government. The government is able to help by putting these amphibians on the endangered list and providing laws to protect them. Putting restrictions on areas where these frogs live to protect their population can help these frogs grow, and those who disturb their population should be fined. Another way these frogs can be helped is to promote volunteering for nonprofit organizations such as Tule Ponds. By promoting volunteering, habitats can be restored by acts such as clearing out invasive species, like we did during our service project. Lastly, regulating trade can significantly help while protecting these frogs. This prevents invasive species from taking over the native ones and will allow habitats to grow peacefully. By reducing the number of invasive plants in the area, this can protect the habitats of these frogs as well as other

The Mississippi gopher frog (Lithobates sevosus) was registered as an endangered species by the state of Mississippi in 1992. Later, this rare species of true frog was also listed as species that are in danger of extinction by the U.S. fish and wildlife service. Their primary objective of listing this as an endangered species is to identify, protect and restore their population. An endangered species is classify as a species of animal or plant that is at risk of disappearing. Mississippi gopher frog is categorized as a critically endangered (CR) species by the International Union for Conservation of Nature (IUCN). Critically endangered species are the species that are facing a very high risk of going extinct in the

The novel, The Adventures of Huckleberry Finn, and the short story, “The Celebrated Jumping Frog of Calaveras County,” both written by Mark Twain, are similar in terms of Twain’s style using figurative language, syntax, and different types of diction.

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
