Virtual Ecology Lab: Invasive Species Worksheet Learning Goal: To learn how an invasive species can affect an ecosystem. Prerequisite Knowledge: Before beginning this lab‚ you should be familiar with these concepts: the definition of invasive species the types of interactions that occur between different species in an ecosystem Introduction: Ecosystems are webs of intricately balanced interactions. But what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s

Species had introduced to Australia by human since 1788. When a foreign species had successfully out-compete native organisms for food and habitat‚ it may survive and reproduce. However this species can become invasive when there is an excessive increase of population which can cause enormous damage to the ecosystem. The impacts of the foreign species could be immense‚ insidious and irreversible. In Australia‚ invasive species have been recognized one of the most serious threats to biodiversity

Should the Endangered Species Act Be Strengthened? Most of us do not realize how much we take for granted‚ but there are some out there who feel as I do when it comes to strengthening the Endangered Species Act. This law is essential to present and future generations‚ although we may not realize it. Humankind is lucky to live in such a variety of ecosystems‚ but unfortunately‚ we all happen to leave some type of mark on the Earth and share in the destruction of many species‚ as well as their habitats

Degrading Importance of the Endangered Species Act The purpose of the Endangered Species Act is to protect and recover imperiled species and the ecosystem upon which they depend on. Since 1973 the Endangered Species Act has saved endangered and threatened species from extinction. The Endangered Species Act‚ also known as the ESA‚ is a list of approximately 2‚195 endangered or threatened species. For a species to be considered endangered and listed onto the ESA‚ the species has to be in danger of extinction

Charles Darwin in his book‚ On the Origin of Species‚ presents us with a theory of natural selection. This theory is his attempt at an explanation on how the world and its species came to be the way that we know them now. Darwin writes on how through a process of millions of years‚ through the effects of man and the effects of nature‚ species have had a trial and error experiment ongoing. It is through these trials that the natural world has developed beneficial anomalies that at times seem too

In taking the challenge of expanding phytochemical studies of Philippines plants and discovering natural products with pharmacological significance‚ an endemic plant species Diospyros blancoi A.DC. is considered for this study. The genus Diospyros‚ under family Ebenaceae‚ is composed of some 475 species common in tropical regions worldwide. Some of them are fruit-producing trees including D. blancoi‚ locally known as mabolo or

important to make sure that no species die out so as to not upset the environmental balance. When we protect all species‚ we are protecting the entire habitat. Therefore‚ we are maintaining the safety of our own environment as humans. To help protect threatened species‚ then-president‚ Richard Nixon‚ signed into law the Endangered Species Act in 1973. Yet after 34 years‚ some still argue that this Act has been a failure. So the question is‚ "Did the Endangered Species Act have more negative effects

The Endangered Species Act (ESA) was passed into law on the 28th December 1973. It was enforced by the United States of America to protect critically jeopardized species from extinction‚ from a consequence of development and economic growth and the conservation of the environment they depend on. There are two main federal agencies that are administered to the act: the United States Fish and Wildlife Service (FWS) and the National Oceanic and Atmospheric Administration (NOAA). A species is considered
