Introduced species

The sustainability of our planet highly relies on the range and dispersion of an organism. An organism's range is the area where the species lives during its life. There are many different organisms with many different ranges -- some are very limited because an organism has special, specific needs, and some can be very large because an organism has the ability to survive in many places or migrates during certain times of the year. The pattern of an organism's spacing in an area is called…

a walnut, while the shell is broken with its beak.Parrots are birds of the roughly 350 species in 85 genera that make up the order Psittaciformes, found in most warm and tropical regions. Also known as psittacines (pronounced /?s?t?sa?nz/),[1][2] they are usually grouped into two families: the Psittacidae (true parrots) and the Cacatuidae (cockatoos). Parrots have a pan-tropical distribution with several species inhabiting the temperate Southern Hemisphere as well. The greatest diversity of…

Species do change over time because of competition, adaptation, the environment and the history of the species and the earth. Competition makes a species stronger, faster and more agile. In order to survive, a species has to adapt to its environment and other organisms in that environment. Competition is only one of the reasons species change over time. In activity 3, the finches have different types of beaks. If a finch with a small beak goes up against a bird with a larger beak in the fight…

supply, habitation, influencing the density of predators or occurrence of disease (biological control) (Fred, 2008). Manipulative strategies are used usually when a population is to be harvested or when it is observed that the numbers of a certain species has exceeded the carrying capacity of the area (over population) or when its densities become too low. Such manipulative decisions according to Fred (2008) are subjective and therefore could be debated by other interest groups in the wildlife…

removed of technology, this species would not have survived as long as we have: since we do not have much hair, we would have frozen to death because there would have been no way to create and keep a fire going to warm us up enough to stay alive and keep predators away. If there was an encounter with a predator, the predator would have most likely prevailed due to our inferiority in strength and speed. The aid of technology has made us evolve into the smartest species dominating the earth. As we…

(cabbage/mustard) family. This species is an herbaceous annual or biennial field mustard. Europe is thought to be the origin of the species. However, many variations, including turnips, bok choi, and cabbage are known to have advanced in areas of Asia. B. rapa has now been introduced to natural and artificial habitats throughout the world via commercial cultivation and personal gardening. B. rapa presents significant phenotypic diversity. Generally speaking, this species has flat roots, large…

NOVA documentary explores differences between skull and bone structure of the body, as well as the brain itself. Another area explored is how our brains process and react differently among species. Scientists have investigated our DNA to studying MRI’s of the brain patterns. Human comparison to other species were another area explores regarding abilities for tool making and the reaction while creating these tools. Researchers desperate to answer the long-asked question, What makes us human”,…

Conservation of wildlife is an issue that is relevant to today in people’s everyday life. The importance of this topic, was not introduced recently. Although a poem published in 1967, still have relevance today shows the importance of modern contemporary poets, whose voice can be heard to this day. W.S. Merwin’s “For a Coming Extinction” emphasizes the importance of saving animals and the environment that is still relevant to today’s issues. In this short poem, concepts of everyday wrong-doing…

Over the past decade the accounts of various coral diseases have been on the rise which had lead to the decimation of keystone species of corals throughout mainly the world’s tropical oceans. Since the mid-1990s, 18 coral diseases affecting at least 150 scleractinian, gorgonian, and hydrozoan zooxanthellate species have been described in the Caribbean and Indo-Pacific (Sutherland et al. 2004). Most of these diseases have been caused by bacterial, fungal, and protist type pathogens as well the…

Xenocide by Orson Scott Card, the ideas between protagonist and antagonists vary because each type of living being on the planet, Lusitania, is going against each other for the greater good of their own species. The humans are dying off from the descolada, a disease that the pequeninos, an alien species that are structured like large pigs who can walk and talk, need in order to survive and move on to their third life as “fathertrees.” And the humans are trying to tame this descolada and have it…
