30 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.

31 Loss of Diversity Natural Hazards Habitat Destruction (Fragmentation / Loss) Agriculture Exotic Species Introduction Pollution Hunting, Collecting, Harvesting

37 Tropical Rain Forests

38 Tropical Rainforests Why are they vulnerable ecosystems? What are there contributions to biodiversity?

39 Species: What are we dealing with? How many species currently? - how are they organized? Past and present Extinctions?

47 Why do Species Become Extinct? Numbers of… Degree of Specialization Distribution Reproductive Potential Behavior Tropic Level

48 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

49 Why do we save species? Arguments for are related to: Ethical considerations Aesthetic considerations Genetic Resource considerations Commercial considerations Life-Support/Ecosystem Support Functions

50 Designing Protected Areas

54 Species Based Conservation

55 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.

56 Captive Breeding Programs
