The yellow stingray is a member of the Urolophidae, or round ray family. The scientific name for a yellow stingray is Urobatus jamaicensis, which originates from the Greek words “oura” meaning tail and “batis” meaning a ray. It is most commonly called the yellow stingray, but can also be known as round stingray, yellow spotted stingray, and the maid stingray. (Piercy, 2009) Like other rays of the Urolophidae family, the yellow stingray has an almost round body, or disc body. It has a circular shaped
Clusters and environmental variables Our results showed that species clusters differed in terms of analysed environmental variables. Generally, temperature-related variables (BIO1, BIO3, BIO4 and BIO9) were the key factors responsible for differentiation between the clusters. Elevation and variables connected with the terrain sculpture (WI, TI, TRI and MRVBF) were among the most important topographic variables separating species clusters. The influence of the geological variables (related to the

In the United States alone there are 70 mammals that are recorded as endangered; however the foreign number exceeds 250 (US Fish and Wildlife Service, 2014). The extinction process could be correlated to a natural route; however extinction may also transpire due to environmental differences. Climate variations producing even slight changes in characteristics may have an extreme consequence on an endangered species. Loss of habitation
sediments and other pollutants from operations throughout the North Coast region into the region’s rivers and streams have adversely affected the health of fish species endangered or threatened with extinction. Future pollution discharges pursuant to the waiver for logging will adversely affect Coho Salmon and other endangered or threatened species in the future. (Elkins Cynthia: “Superior court for the state of California in and for the county of Sonoma” page 3) Cutting the trees also reduces our
Problems with Wildlife It is blatantly obvious that the level of wildlife has been decreasing amazingly over the years. Species of animals and plants are rapidly becoming endangered or even extinct. There are many factors that are making this problem a reality. Habitat destruction, hunting, and pollution are the three major factors that are destroying our wildlife. The destruction of habitat is the greatest of all threats to wildlife, whether they’re rich tropical forests, mangroves, swamps, coral
In the year 1973, the Endangered Species Act (ESA) was instituted in order to bring attention to the issue of species that are in danger of extinction as well as to provide conservation of species that are endangered or threatened. Currently, there are around 2,245 species that the Endangered Species Act lists as either endangered or threatened throughout the world, many of which are found in the United States ecosystems and a handful that are only found in foreign ecosystems (Ehrlich 12). Because
those living creatures such as animals and plants died, the ecosystem will not be balanced. However, not all of the creatures can survive in today’s life. In fact, there are so many of animal species that being threatened and become an endangered animal. Even many of them are already become an extinct species. Therefore, to avoid this kind of situation happens in the future, people have to be aware of this major issue and try to conserve them to keep them alive. Because the government cannot solve
extinction of the bison and the passenger pigeon. Ignorance regarding the idea of extinction combined with the popularity of hunting, severely hurt these species. Hunters and naturalists killed wildlife for game and study without much thought for the species’ survival. In addition the rapid industrialization threatened the natural habitats of thousands of species. The first major piece of animal legislation was the Lacey Act of 1900 which prohibited interstate commerce of animals killed in violation of state
Endangered Species Act of 1973. Although the United States government is noble in it's efforts to preserve the environment through these acts, the internal structure of public policy often retards these acts' effectiveness. This paper will explore the many ways in which factors such as horizontal implementation, divided government, and other forms of public policy affect the environmental legislation involved with the aforementioned acts. The main factors involved with the Endangered Species Act of 1973
Endangered Species Act, where he talks about the effectiveness of the Federal government’s current involvement with endangered species. Mr. Middleton, a journalist, compiled an article describing, in his opinion, the flaws of the Endangered Species Act. He then attempts to back his opinion with studied analyses, researched facts, and testimonies. To summarize Middleton’s (2011) perspective, “Rather than provide incentives for conservation and environmental stewardship, the Endangered Species Act punishes
you went? That’s what zoos do, but that’s not all they do. Not only do zoos find creative and fun ways to educate children, but they also save many animals that would not have lived without help. Zoos help publicize endangered species, educate the public, and save many species from the brink of extinction. Some Animal Rights Activists claim that zoos capture animals from their natural habitats for no reason. Zoos don’t just capture animals without reason. They find the young whose mother has been
is the variety of life. Most of the people recognize biodiversity by species but biodiversity is more than just species. A species is a group of living organism that can interbreed for example white-tailed deer, blue whales, and bacteria that you cannot even see with your eyes. Species is only one part of biodiversity. Biodiversity can be studied on many levels and at the highest level you can look at all the different species in earth. Biodiversity occurs at multiple scales of ecological organization

Amphibian species are suffering a serious global decline. Disappearances of frogs, toads, and salamanders have been reported in North, Central, and South America, Europe, Asia, Africa, and Australia (Blaustein
huge number of modern medicines are derived from chemicals found in nature. For instance, treatments for childhood leukemia and Hodgkin’s disease have been made treatable by the rosy periwinkle found in Madagascar.

Introduction Biological diversity provides humans with food, energy, medicines and many other resources. Saving endangered species is not only about the moral implications, there are very important economic and scientific implications as well. For example, bee loss means a direct decline in our agricultural industry, leading to scarcity and further economic burdens to provide food. It is also important to note extinction is a natural ecological process. However, humans are causing the extinction
of Zoos and Aquarium’s (AZA’s) Species Survival Plan (SSP) Program, which aims to manage the breeding of specific endangered species in order to help maintain healthy and sustaining populations are present in several zoos around North America. This program focuses on conservation breeding, habitat preservation, field conservation, and supportive research to ensure survival for many of the planet's threatened and endangered species. According to the AZA, the Species Survival Plan Program has brought
past 40 years? Can you imagine living in a world without animals? According to The World Wildlife Fund, “Earth has lost half of its wildlife in the past 40 years”. Everyday, species across the world are vanishing due to destruction of habitat, poaching, illegal hunting and fishing by humans. Earth has lost half of it species over the past 40 years and we the Humans are largely responsible for it. WWF's (World Wildlife Fund) scientists recently discovered 38 percent of land animals population decreased
Biodiversity includes not only species we consider rare, threatened, or endangered, but every living thing — even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well
