Frog Extinctions as Indicators of Environmental Problems...

Tiny or large, smelly or poisonous, there are many kinds of frogs and are excellent indicators of the quality of the overall environment. To this day, scientists continue to find new varieties of frogs never been discovered all over the world. Recently, tiny frogs [its scientific name is Eleutherodactylus Iberia, smaller than a U.S. dime, were discovered under old leaves in Cuba in 1996 (â€Å"The World’s Smallest Frog†). See-through glass frogs were discovered in the Upper Nangaritza Basin in southeastern Ecuador which had previously been known to live only in one area of northeastern Peru (Ugly Salamander Among New Species Found in Ecuador†). An individual may think finding new frogs is a good indication that there are many of them in†¦show more content†¦Their larvae [tadpoles] have gills [to allow them to breathe in water] and develop in water. Many tadpoles are eaten by fish, birds or other frogs and they eat algae or tiny organisms in water. Large f rogs eat insects, mice, bugs, and worms. In size, they range from 10mm [0.39in] such as the Eleutherodactylus Iberia of Cuba to 300mm [12in] such as the Conraua goliath of Cameroon (â€Å"Frog†). In the spring, male frogs and toads move to watery breeding sites and start calling to attract females and in some cases to warn other males to keep away from their territories (â€Å"Frogs†). 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 (â€Å"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,Show MoreRelatedShould We Save Endangered Species?1740 Words   |  7 Pagesprotect and preserve endangered animals? The reasons for saving endangered species might seem obvious to many people, but many question why we should save a species from dying out. Isn t this part of the process of natural selection? Is there any environmental benefit to preserving a dying species? For some it s a question with an obvious answer, for others... it requires some thought. What benefit is there to saving an endangered species from dying out?

Brain cells shrivel and muscles seize. The kidneys shut down. Blood volume drops, triggering hypovolemic shock, with its attendant respiratory and cardiac failures. These combined assaults disrupt the chemical and electrical pathways of the body until all systems cascade toward death.

It is the context that makes a problem meaningful and something worth considering. For example, exercises that ask students to compute the mean of 10 numbers or to construct a dotplot or boxplot of 20 numbers without context are arithmetic and graphing exercises. They become statistics problems only when a context gives them meaning and allows for interpretation. While this makes for a text that may appear â€Å"wordy†
