Threatened species

pressure that would ultimately threat the survival of the herbivores as well. Thus, carnivores can provide ecological boundaries that protect weaker competitors from competitive exclusion (Miller et al., 2001). Some carnivores are regarded as keystone species due to the enormous ecological effects they impose on other…

The hoatzin (Opisthocomus hoazin), also known as the stinkbird, or Canje pheasant, is a species of tropical bird found in swamps, riparian forests, and mangroves of the Amazon and the Orinoco Delta in South America. It is notable for having chicks that possess claws on two of their wing digits. It is the only member of the genus Opisthocomus (Ancient Greek: "wearing long hair behind", referring to its large crest) which in turn is the only extant genus in the family Opisthocomidae. The taxonomic…

or more. Iguanas seem to prefer rocky shores but may also be found in mangrove swamps and beaches. The iguanas can dive over 9 m down into the water. The lava lizard is a reptile which are native to South America. There are around 20 recognized species but only 7 of them are found on the Galápagos Islands. Lave lizards are omnivores and eat moths, flies, beetles, ants, spiders, grasshoppers and many other things. Lava Lizards can grow to be up to a foot in length, but are usually about 5 – 6…

The bestiary genre has existed for centuries, introducing and entertaining its readers with compilations of both stories and facts about creatures who are familiar, unfamiliar, real, and imaginary. In some aspects, Henderson’s The Book of Barely Imagined Beings, a 21st century bestiary, is no different, since it still incorporates beasts ranging from the fire-defying salamander to the intelligent macaque. However, in other ways, this bestiary diverges from previous ones. Henderson’s bestiary…

I choose to do my write my paper on endangered species Act. The reason I choose to do my paper on that is, because I love animals and they are very interesting to me. The endangered species act started in 1973. The endangered species Act of 1973 is one of many United States environmental laws passed in the 1970’s. Why should we protect threaten and endangered species? The Endangered species Act is America’s most powerful wildlife and protection law. This act have been the most positive for…

What is the Endangered Species Act? Why was the Endangered Species Act created? Why do we care for endangered species? The Endangered Species Act was made so that our native plants, animals, and fish would not go into extinction. This Act requires that Federal and State agencies provide suitable conditions for endangered and threatened species, not to jeopardize from federal activities but to protect and save our native species from extinction. Throughout history there have been many events to…

Both invasive species present a danger because they overtake the habitat of other plant life. The Rosarypea can grow over small trees and shrubs, and its roots can grow very deeply onto the ground and are very difficult to remove. The Earleaf acacia is more common in disturbed areas. It has also invaded pinelands, scrub, and hammocks and can displace native vegetation and shade out native plants. It is adapted to nutrient-poor soils in humid tropics and is fire adapted. According to our textbook…

estimated that every day we lose 150-200 species from this Earth. Of the 44,838 species that have been assessed, 16,928 are listed as endangered, meaning they are threatened with extinction. The rest of the estimated 8,700,000 species on Earth have yet to be assessed, so the number of threatened species is significantly larger than the current estimate. In the 1970s, many environmental laws were passed to curb the mass extinction of species including the Endangered Species Act of 1973 or ESA.…

With the biotic world still being destroyed and harmed at an alarming rate, entire biomes are endangered and whole ecosystems are threatened by anthropogenic pressures. These changes globally have impelled zoos and aquariums to create and establish conservation benefits. This coupled with the growth in economic rationalism and the rise of corporate management, rationalises the feasibility of projects in terms of economic efficiencies. Which has seen the battle between balancing of public…

or different human-caused factors (Endangered Species Act). Subspecies and clear population segments are given protection if it is proven that the organisms are crucial to an ecosystem (Matsumoto). The law requires that the listing of a species is based solely on biological status. It is illegal to list or delist an organism when there is insufficient scientific data to support the conclusion. It usually takes less than a year to add or remove a species from one of the lists. During an…
