Species Interaction * The relationships between two species in an ecosystem. * The interactions between two species need not be through direct contact. Species may affect each other through intermediaries such as shared resources or common enemies. Major factors in evolution and adaptation: * Predation * Competition for scarce resources Terminologies: * Habitat – the actual physical location where a species lives. * Conditions – physical or chemical attributes of the

based on the study of ‘Species Diversity and Ecosystem Stability’ of the New Amsterdam Secondary School’s Eastern Field. This study was carried out by yours truly‚ Cynthia Rutherford‚ from the 26th January‚ 2011 to 5th February‚ 2011. Even though the study was done over a short period of time‚ I do hope that it will be lots of benefit to you the readers and edify you of our environment. Thank you.

Chapter 11: 1-19 1. The management strategy changed from setting an annual total allowable catch (TAC) and allowing the fishing fleet to fish until the TAC was reached. In 1990 the fishing season was only 6 days‚ most of the fish caught had to be frozen‚ gear was lost or damaged‚ and crews were endangered when the weather was bad. Now the individual quota system is used‚ so owners of fishing vessels can decide when to fish within a season that last(s) as long as 8 months. The fishers got an increase

Endangered Species By: Jennifer Petley There are currently only 30 individual Amur leopards left in the world‚ the hawksbill turtle has been deemed “critically endangered”‚ the black-footed ferret who was once thought to be globally extinct has only a population of 1000‚ the black rhino was said to be “doomed to disappear from the face of the earth” in 1961‚ and the Saola deer has an estimated population of a few hundred at a maximum‚ or possibly only a few dozen at a minimum.

Ocean‚ ranging from Canada to Southern California and even Mexico. This species ranks as the second smallest marine mammal in the animal kingdom and is known for its dense fur coat‚ as opposed to a layer of blubber (http://www.defenders.org/sea-otter/basic-facts). The sea otter is a keystone species. A keystone species is “a species on which other species in an ecosystem largely depend‚ such that if it were removed the ecosystem would change drastically” (https://www.google.com/webhp?sourceid=chro

Charles Kay’s article‚ “Aboriginal Overkill and Native Burning: Implications for Modern Ecosystem Management‚” describes the apparent flaws in western environmental policy for park management. He describes how the current park management strategy is based on false interpretations of the perceived pre-Columbian‚ North American wilderness conditions and a desire to return to those conditions. Kay uses three major premises (intermediate conclusions) to support his argument against park policy and counter

Odessa Tumbali The Interactions and Interrelationships among the Different Components of the Ecosystem I. Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population‚ community‚ and ecosystem ecology although it also includes

relationships in ecosystems and the devastating effects of human interference. As a result we have become increasingly aware of the need to protect and manage the ecosystems that we do have remaining for their utility‚ genetic‚ intrinsic and heritage values and also for the need to allow natural change and thus evolution to take place. Natural ecosystems have provided much that has been of benefit to humanity and with careful protection it can last for many more generations. Management strategies involving
