Presentation Transcript

  1. Ecology: Preserving the Animal Kingdom Chapter 6

  2. The study of how natural processes affect the size, composition and dynamics of a population

  3. Review Words • Population • Community • Ecosystem • Biosphere • Ecology • Density-dependent • Density-independent • Exponential Growth • Logistic Growth • Biotic • Abiotic • Carrying Capacity • Survivorship Curve • Competition • Parasitism • Commensalism • Mutualism • Niche • Succession • Trophic Levels

  4. Animals and Their Abiotic Environments • A habitat includes all biotic and abiotic factors • Animals operate best when in their typical tolerance range • The range of optimum defines the conditions under which an animal is most successful • When does a factor become limiting?

  5. Controlled Hypothermia • Periods of decreased body temperature and metabolism in animals • Survival mechanism to help animals through harsh conditions • Torpor – Daily • Hibernation – Weeks or Months • Winter Sleep – Months • Aestivation – Months or Years

  6. Interspecific Interactions • Predation • Competition • Coevolution • Symbiosis • Coloring (camouflage, cryptic coloration, countershading, aposematic coloration) • Mimicry

  7. Age Structure Diagram

  8. Project/Presentation • You may work with a partner • The assignment is due next Tuesday, with presentations (3 minutes minimum) beginning that day • Presentation must include visuals and a handout • Choose from the following topics: • Coevolution • Land and Freshwater Use • Ocean Acidification • Human Population
