  1. Lesson 1 What is Ecology?

  2. What is Ecology? • The Study of how Nature works • 2 Parts: • Biotic – living part (plants, animals, fungi, etc) • Abiotic – nonliving part (water, sunlight, temp.) • Any living thing is affected by both parts • Ecologists study relationships between abiotic and biotic parts of the environment.

  3. How are organisms, populations, communities, ecosystems and the biosphere connected? • Ecologists try to learn: • how living things are affected by and respond to their environment • What factors contribute to an increase or decrease in a population • How the various interactions in a community affect the populations involved

  4. Interactions continued • Ecologists try to learn: • How energy is transferred in an ecosystem • How atoms cycle through the environment • How physical processes, such as fire or flooding affect the communities in an ecosystem. • How global processes affect different ecosystems • How things in one ecosystem affect other ecosystems.

  5. How do Ecologists conduct research? • Make observations, ask questions and collect information • Write hypothesis containing IV and DV • Test • Analyze and interpret data • MORE QUESTIONS???

  6. Examples of Questions • Organism: How does water temp. affect bullfrog behavior? • Population: How many river otters can the Grand River watershed support? • Community: Do red-winged blackbirds and marsh wrens compete for nesting sites? • Ecosystem: How fast does nitrogen move through a wetland ecosystem? • Biosphere: How much carbon do Missouri wetlands remove from Earth’s atmosphere?

  7. Why is Ecology important? • Ecological systems provide the life support functions all life needs. • Ecological systems provide us with an infinite number of products. • If systems break down, we need to know how to “fix” them, if we can. • Our lives depends on it!

  8. What is Resource Management? • Resource Management is an applied science. • Resource managers apply principles learned from ecology to protect, maintian and restore healthy ecosystems.

  9. What is Conservation? • A way of using resources that keeps them healthy and intact for use by future generations. • Maintaining harmony between people and the land is a responsibility for all of us • Learning about ecology is one way you can make wise decisions about how you use natural resources.

  11. Activity 1.1 • Questions to think about: • What factors, if any, were difficult to label as biotic or abiotic? • How did weather conditions affect what you saw? • What abiotic and biotic factors did you expect to find? • What were you surprised to find? • How might a resource manager use the information collected?
