1. Invasive Species and It’s effect on Bio Diversity Every animal species has a native habitat. On occasion, humans relocate a species, either through carelessness or with the intent of benefiting human beings, the species itself, and/or a new environment

2. Invasive Species Defined 1) non-native (or alien) to the ecosystem under consideration and1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health*2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health* *http://www.invasivespecies.gov/

3. Bio Diversity Defined 1) Bio diversity is the variety of life and its processes.1) Bio diversity is the variety of life and its processes. 2) It can be considered the fabric of life ––thousands of individual threads woven into a complex tapestry across the landscape. *2) It can be considered the fabric of life ––thousands of individual threads woven into a complex tapestry across the landscape. * *Oregon Bio Diversity Project

4. Bio diversity is central to our quality of life. It supports natural resource industries that produce commodities such as fiber, fuel, food, and medicine, as well as recreational uses.*Bio diversity is central to our quality of life.

5. SPECIES EXTINCTION Species can become extinct: –Locally: A species is no longer found in an area it once inhabited but is still found elsewhere in the world. –Ecologically: Occurs when so few members of a species are left they no longer play its ecological role. –Globally (biologically): Species is no longer found on the earth.

6. Global Extinction Some animals have become prematurely extinct because of human activities.

7. Endangered and Threatened Species: Ecological Smoke Alarms Endangered species: so few individual survivors that it could soon become extinct. Threatened species: still abundant in its natural range but is likely to become endangered in the near future.

8. Climate similar to habitat of invader Absence of predators on invading species Early successional systems Low diversity of native species Absence of fire Disturbed by human activities Characteristics of Successful Invader Species High reproductive rate, short generation time (r-selected species) Pioneer species Long lived High dispersal rate Release growth-inhibiting chemicals into soil Generalists High genetic variability Characteristics of Ecosystems Vulnerable to Invader Species
