Amphibian

Dart’s and Arrow’s. Most people do not know how the poison dart or arrow frog got its name. They are some of the most poisonous amphibians in the world the most deadly being the golden poison dart frog. Adaptation and The Poison Dart Frog’s characteristics has allowed it to survive in the jungle for many years. They have adapted to jump from place to place with ease. The reason they jump so far is because of their tendons are being stretched, to the point where they release and snap like a…

they serve as the basis of a food web/chain with small insects, birds, mammals, fungi and bacteria. Beavers for example depend highly on the willows because they use them for dams and lodges. Next, the beavers provide a pond to many reptiles and amphibians. In return this increases many of different animals up and down the trophic levels. An ecosystem will become less diverse as there are changes from different trophic levels, a term called trophic cascades will begin to occur as the apex…

It is a common misconception that the world will never run out of water yet fresh water is a finite resource. Major implications will occur if the public continues to participate in unsustainable water treatment. By no fault of their own, however, most people are unaware of water-scarcity as well as the devastating consequences that can arise. “Entering an Era of Water Scarcity: The Challenges Ahead”, written by Sandra L. Postel, aims to shift the narrative of water security by informing the…

Unfortunately, there is a misconception that wetlands are wastelands, despite their value to our environment, society and economy. Our wetlands are threatened by numerous activities. Global Warming Global warming has the potential to alter the structure and function of our wetlands. Sea level rise threatens to inundate many coastal wetlands, with little room to move inland because of coastal development. Warmer water from global warming will alter the species composition and contribute to…

A park ranger named Daniel told me that the park holds over 19,000 species of wildlife that have been identified, but it is thought that there are actually over 80,000 species. It holds approximately forty-three amphibian species, thirty-nine reptile species, sixty-seven fish species, sixty-eight mammal species, 200 bird species, and 1,500 flower species. Daniel also told me that a few of the taller mountains get fifty-five to eighty-five inches of rainfall per year…

Chester Elementary Teachers Preparation for Outdoor Core/NGSS Rollout Over the last three years, Chester teachers, Kellie Bainbridge, Janae LaGroue, Aletha O’Kelley, Meghan Whalen, Brooke Geer, Nicholle Crowther, Susan Tantardino, and Camille Klimek, have taken on a huge responsibility in our district, by agreeing to pilot Next Generation Science Standards ( NGSS).They have been the pioneers willing to dissect and deconstruct NGSS to create a curriculum guide and instructional plans that would…

Lab 3: Stimulus strength vs. muscle force production Introduction: The goal of this lab is to determine the relationship between stimulus amplitude (strength) and the contractile properties (i.e. force) of the frog gastrocnemius muscle. Skeletal muscle is composed of bundles of muscle fibers called myofibers. These fibers are themselves composed of myofibrils, which are comprised of the ordered arrangement of actin and myosin. These proteins slide past each other in the presence of calcium…

species, genetic engineering unleashes numerous unpredictable side effects, such as two viruses mixing to create a supervirus, increased body toxicity and death. Third of all, GMOs harm the environment. Genetically modified crops harm birds, insects, amphibians, marine ecosystems and soil organisms. They lessen bio-diversity, contaminate water resources, and are unsustainable. For example, GM crops are wiping out the monarch butterflies’ habititat, whose populations are plummeting. Last of all,…

Understanding evolution is important because not only does evolution help humans to advance their knowledge in medicine and modify characteristics in plants, it also helps us to uncover the answer to the deepest question known to man, “Where do we come from?” The more evolution is studied and dissected, the more of benefit it is to us and our growing knowledge of earth and it’s history. Just like evolution itself, uncovering the many answers evolution supplies us with takes a lot of hard work…
