Protecting Pesticides In Frogs

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.

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)

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

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

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

Over the last thirty years or so the population of frogs has begun to decline across the world. Not only until

wellbeing of the frog and what happened to the frog after it was used. People today are more cautious

A news study has found that ponds in suburban areas have almost twice the proportion of female frogs to male frogs than isolated, forest-bound ponds. The estrogen in suburban wastewater disrupts frogs' reproductive systems, causing them to spawn far more female frogs than male frogs, and in effect threatening the entire species and ecosystem.

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

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.

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

This scholarly text book, part of a series called Current Controversies, is composed of primary sources taken from a diversity of informational categories including books, newspapers, periodicals, international government documents, and the publications of organizations. The authors in this series examine some of the issues that typical arise in the debate about pesticides, including whether they are detrimental to human health, animals and the environment, whether they are essential to curtailing international hunger, and what the future of pesticides might be. This book widely mirrors the mosaic of opinions in both parts of the debate regarding the benefits and harmful effects

One species that continues to dwindle are amphibians. The book begins with Kolbert’s trip to Panama where she discovered amphibians were decreasing at an alarming rate. During her trip, she finds that over 7,000 species of amphibians were becoming extinct worldwide (Kolbert, Page 11). Kolbert’s assumption that a sixth extinction is under way proves to be true because there is a continuous decrease of amphibians today. Camila Ruz states in her article that “Around half of amphibian species are in decline, while a third are already threatened with extinction,” (Ruz, 2011). The reasons supporting this dramatic decrease revolves around climate change and habitat loss. The impact of

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.

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
