Ecology: Preserving the Animal Kingdom Chapter 6

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

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

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?

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
