Lecture 17

Question 1

Why should we care to protect biodiversity?

Answer 1

Ecosystem services

Question 2

What are the four types of ecosystem services?

Answer 2

1. Supporting services
2. Provisioning services
3. Regulating services
4. Cultural services

Question 3

What are supporting services?

Answer 3

benefits of biodiversity that are important but maybe indirect
ex- pollination

Question 4

What are provisioning services?

Answer 4

products such as foods, fiber, medicinal and cosmetic products

Question 5

What are regulating services?

Answer 5

carbon sequestration, climate and water regulations, water and air purification, mitigating the effects of natural hazards such as hurricanes and floods

Question 6

What is the example(s) of regulating service given in class?

Answer 6

• Catskill/Delaware watershed- supplies 90% of NY city water

- 2004 Indian oceam tsunami

Question 7

What was discovered from the 2004 Indian ocean tsunami?

Answer 7

There were some villages protected by vegetation- mangroves and other vegetation reduced the impact
- 30 trees per 100 sq m may reduce max tsunami flow by 90%!

Question 8

What helps reduce disease transmission to humans?

Answer 8

According to the summary of case studies linking biodiversity change to health effects in humans, a high diversity of host animals decreases the burden of many vector-borne diseases

Question 9

What is the future of biodiversity?

Answer 9

Pressures (direct and indirect) from a growing and urbanizing human population will negatively affect species and ecosystems over the next century

Question 10

What is the future of biodiversity in terms of the task for science?

Answer 10

• is to try to predict the fates of individual species and ecosystems and the biological and environmental consequences of any loss
• can also suggest ways to minimize our impacts
