1. Introduction to Ecology

2. What is ecology? Ecology is the science by which we study how organisms (animals, plants, microbes) interact in and with the natural world. Robert E. Ricklefs. 1997. The Economy of Nature 4th ed. W.H. Freeman and Company. New York.

3. Environment Living components All need sun, air, water, and earth All grow, eat, drink, breathe, move, have babies Non-living components

4. Habitat Where something lives Can be defined as a big or small area A tide pool Pacific Ocean

5. Classification of Living Things 7 levels of classification: kingdom, phylum, class, order, family, genus, species. Kingdom plantae is composed of multi-celled organisms that grow from embryos that are usually the result of sexual fusion of a male and female cell. Kingdom animalia is comprised of multi-celled organisms which develop from an embryo resulting from the fertilization of an egg by a much smaller sperm. Genus and species are combined to form the latin name. General grouping (plant, animal, etc.) Common name

6. Relationships How do populations interact? Predation Competition Co-operation Symbiotic relationships Parasites Mutualist Commensualists

7. Adaptations Any physical or behavioral feature that helps an organism survive. Beak and teeth shapes Camouflage vs. bright coloring Habitat adaptations

8. The Niche A niche is the role of a species in their environment. No two species hold the EXACT same niche Shore birds (same place, different prey) Eastern and Western bluebirds (same role, different place) Tidal zone (same apparent place, but actually very different places)

9. Food Webs vs. Food Chains Parts of a food chain: Producers —make their own food Primary Consumers—eats producers Secondary Consumers—eat other consumers Decomposer—”eats” and breaks down dead material What is the difference between a food web and a food chain?

10. Ecosystem Services The modern system for giving economic value to the environment. What benefit does a feature of the environment give us and what would it cost to provide that service through human built means? A major focus in the Education and the Environment Initiative (EEI) learning objectives.

11. Human Ecology Human beings have a unique interaction with our environment. Tool-use became technology Communication became language Produce garbage Move beyond ecological constraints

12. Sustainability Principals Preserving Restoring Practicing Conserving Understanding Possible!

13. We are a part of nature, not apart from nature.... We have succeeded famously in becoming the technological species. Our survival now depends on our becoming the ecological species and taking our proper place in...nature.
