Course Philosophy• Learn products = ‘What do we KNOW’ @ ecology’ and processes of science = ‘How to DO ecology…’

• Become well-informed citizens about the link between ecology and human-induced problems

• Develop higher levels of thought

• Use active learning Tell me and I’ll listen Show me and I’ll understand Involve me and I’ll learn Teton Lakota Indian

Today’s Outline• What is ecology? (basic + applied)• What are most pressing environmental issues?• Hierarchical levels of biology/ecology• Questions asked at each level of ecology• Introduce Labs I-III: ‘Small mammals, plants,and insects in succession habitats’• Practice skills used in scientific process

We write to learn…• What is ecology?

• How do basic vs. applied ecology differ?

• How does basic contribute to applied?

• What are 5 most pressing environmental

issues? Which is # 1?

•How does ecology help to solve human-

induced problems?

What types of questions do ecologists ask?• Descriptive:

What? When? Where? Who?

• Functional:

How?

• Evolutionary

Why?

• Hierarchical levels of biological organization…from molecules toorganisms…

• Ecology starts with individual organism…and goes to higher levels of biological organization.

The hierarchical nature and processes of different levels of ecological systems:

• Individual organism: How do structure, physiology, and behavior lead to the individual’s survival and reproduction?

•Population: What determines the number of individuals and their variation in time and space?

• Community: What determines the diversity and relative abundance of organisms living together?

• Ecosystem: How do energy and matter move in the biotic and abiotic environment?

• Biosphere: How do air, water, and the energy and chemicals they contain circulate globally?

How DO Ecologists Study the Natural World?

Introduction to Labs I-III‘Small mammals, insects, and

plants in successional habitats’

What is level of ecology?

Food web

4-5 yr (leaves/stems

seeds

Insects/spiders

predators

What questions can be explored in this food web in

these successional habitats?

• Does succession affect the distribution and abundance of organisms?• Does plant and arthropod biomass differ between 1 vs. 5-yr plots?• Does abundance of small mammals differ between 1 vs. 5-yr plots?• What factors determine habitat choice of small mammals?
