Amphibian Diversity: Article Analysis

Improved Essays
NEWS STORY SUMMARY
Dr.Raffael Ernst and colleagues at the Senckenberg Natural History Collections studied how abandoned forest roads in the rainforest of Central Guyana impact amphibian diversity. The study suggest that these roads serve as a sanctuary for amphibians during severe dry periods to enhance their survival and reproduction. For example, the water-filled potholes of roads act as spawning grounds. Researchers suggest these roads should not be disturbed as they are advantageous to amphibians during dry periods. However, this is not to encourage the establishment of new roads or restoring of old ones as there are different factors that should be considered for restoration initiatives. As a consequence of species ability to adapt to

The news article primarily emphasizes the point that infrastructure, namely roads, in Central America can be beneficial on frog populations and should not be restored because amphibian species have learned to adapt to human intervention. (Senckenberg Research Institute and Natural History Museum 2016). The research states that active roads have a negative influence, but fortunately moderate infrastructural modifications may provide frog populations with more potential of breeding locations (Cosentino et al. 2014). Essentially, both the news article and research article are directed towards a central theme where amphibian populations can benefit from human intervention, if they can find a means of adequately adapting. The news story emphasized how the frog species Hypsiboas boans adapted to old roads of Central America, thus in this case conservation efforts would likely be better spent on initiatives other than restoration. In contrast, the research presents an array of negative effects that functioning roads due to frequent human disturbances of traffic have on mortality and mobility of amphibian populations, while also mentioning the positive effect modest human development has on amphibian frog reproduction and richness. While initially, these two articles seem to present separate viewpoints on the impact of roads – they are actually supportive of each other and intimately linked. The research reinforces the idea presented in the news article that abandoned human roads have an adaptive function of serving as breeding sites, whereas in the research study active roads were sites of high mortality. Thus the proposal made by the news article to leave existing roads intact for frog reproduction is validated. Analyzing, the research does change our perspective on the news story. The news story portrays human

    Yamashita illustrates the forest by saying, “...the Amazon Forest was a great decaying hothouse where all sustenance was sucked up immediately by the voracious flora and fauna, leaving nothing for the poor soil” (99). The Amazon Forest, the home to epiphytes, spiders, alligators, birds, monkeys, and millions of other species, is functioning in a cycle of life and death. Native plants and animals feed off of the fatality of others through the recycling of nutrients. Originally thought to be “virgin soil,” the ground of the rainforest has little to offer because of the lack of nutrients stored there. This natural cycle is often interrupted by humans.…

    In the article, “Which Species Will Live?” by Michelle Nijihuis, she explains in her article her thesis and the main point, which is, that as a society, we need to make stronger efforts to save more species and to not just let them die out just because they do not deserve a position that is valuable enough for this society. She compares also what society should be accomplishing to a battlefield medic who, “works unstintingly to save lives, even while knowing that he or she cannot save them all.” This was an attempt to discuss her point on how individuals should attempt to save species if, once again, they are not able to be saved or even helpless.

    Every year, many plants and animal species are killed, or even put to the brink of extinction, due to Amazon Deforestation. “Forests are complex ecosystems that affect almost every species on the planet. When they are degraded, it can set off a devastating chain of events both locally and around the world.” (Bradford) By deforesting the amazon, many animals are losing their homes and food sources.…

    Brazil's first conservation prohibited the burning or destruction of forests in 1797, and the government has continued to develop further plans to protect the forests. (Pearson) Conclusion Though the introduction of European settlers, deforestation, and animal smuggling has increased the rate species endangerment in Brazil, there has been efforts to help slow down the process of animal endangerment and help conserve the rainforest in which the majority of these animals thrive in. Helping to preserve these 2,900+ animal species is making a difference for the ecosystem because the species have an irreplaceable role on the ecosystem.…

    Elizabeth Kolbert’s book, The Sixth Extinction, covers the argument that we are currently in another mass extinction because the Earth is following similar trends as it did in the past five mass extinctions. The first chapter of The Sixth Extinction starts out by discussing frogs. Frogs are the one of the oldest species on Earth; however, the extinction rates of frogs is higher than it’s ever been, and it’s only increasing. Kolbert then focused specifically on Panamanian golden frogs. Not too long ago, these frogs were plentiful, but recently the numbers have decreased due to human’s introducing a native species to Panama: Chytrid fungus.…

    The first chapter in the sixth extinction is geared towards focusing on the rapid extinction of frogs, a species that has survived over 400 million years. Elizabeth Kolbert, the author believes that we are entering a sixth extinction and that it is crucial to pay close attention to it because any slight change can drastically influence an entire ecosystem and its inhabitants. The epicenter of the extinction seemed to begin in a small town in Central Panama called El Valle de Anton. The Panamanian golden frog was one of Panama’s most iconic attractions. The frog is small, toxic, and has black speckles.…

    Biologists around Quito, Ecuador are on a time limit to remove an endangered frog species before the volcano eruption wipes them out. These endangered frogs are called Hyloxalus Jacobuspetersi; it is a small, chocolate-striped rocket frog. These frogs have adapted to all landscapes and environments in Quito. It has even become found of pastures and backyards of people landscapes and houses. The biologists say that there are just one hundred adults in addition to an unknown number of juveniles and tadpoles that are laying in the Andes along the Rio Pita River; this is a river that has been created from melted snow and ice on a active volcano that recently erupted, the Cotopaxi.…

    The Pucallpa-Cruzeiro do Sul is a road this is being considered for construction. The road should not be built for the following reasons: it could fatally affect the Asheninka and could make multiple species of animals and insects go extinct. This could be extremely detrimental to the flora and fauna found in the Amazon Rainforest. The road should not be built because of the many animal species that are only found in this particular rainforest. Many animals in the Amazon still haven't been discovered.…

    I chose this species because I want to come up with ways to help their depleting population. They are 4-8 centimeters long, and they have stout bodies with a tubercle at the end of both of their hind feet. Because the tubercle looks like a spade, this is where the word “spade” in their name comes from. These toads are said to smell like peanut butter, and those who handle them that have allergies with peanuts may have an allergic reaction. What is different about them from other toads are that they have much smoother skin and have vertically elliptical eyes, almost like a cat’s eyes.…

    Prioritization of activities should start with an assessment of hierarchal needs within each segment that has direct input to potential megafauna’s threats. Some regions may be impoverished leading to the unethical migration to economic gain. These could be attributed to unregulated trophy hunting for profit, or clear cutting natural habitats for commercial food production. Modern-day technology is speeding up the process of clearing habitats by taking less time to clear than it has in the past. Furthermore, natural habitats are being destroyed to make room for urban development and energy production.…

We as humans take rainforests for granted, we only think of them a resources for paper but they are useful for so many other things. They are homes for many species, they keep the ecosystem balanced, and for some people their food.…
