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