To Summarize:

Loss of Diversity

• Identify as many specific factors that lead to a loss of biodiversity.

• Put this into a 30 second “infomercial” that will include everyone’s voice in the group.

Loss of Diversity

• Natural Hazards

• Habitat Destruction (Fragmentation / Loss)

• Agriculture

• Exotic Species Introduction

• Pollution

• Hunting, Collecting, Harvesting

Tropical Rain Forests

Tropical Rainforests

• Why are they vulnerable ecosystems?

• What are there contributions to biodiversity?

Species: What are we dealing with?

• How many species currently?

- how are they organized?

• Past and present Extinctions?

Why do Species Become Extinct?

• Numbers of…

• Degree of Specialization

• Distribution

• Reproductive Potential

• Behavior

• Tropic Level

• Population Size• Reduction in Population

Size• Numbers of Mature

Individuals• Geographic Range and

degree of Fragmentation

• Quality of Habitat• Area of Occupancy• Probability of Extinction

Why do we save species?

Arguments for are related to:

• Ethical considerations

• Aesthetic considerations

• Genetic Resource considerations

• Commercial considerations

• Life-Support/Ecosystem Support Functions

Designing Protected Areas

Species Based Conservation

CITES: (the Convention on International Trade in Endangered

Species of Wild Fauna and Flora) is an international agreement between governments. Its aim is to ensure that international trade in

specimens of wild animals and plants does not threaten their survival.
