What terms refers to the interaction between predatory animals and the animal prey they consume?
Predation
What is a mathematical model that predicts an animals diet?
Optimal foraging theory.
What does aposematic mean?
Unpalatable species advertising themselves as aposematic.
What are the 2 types of mimicry?
Batesian and Mullerian.
What are the 2 types of competition?
Interference and Exploitative.
Interspecific model looks like what kind of growth?
Logistical.
What is it called when 1 specie survives better than the other because it can harvest its resources more efficiently?
Competitive Exclusion Principle
What are ecotones?
Transition zones between adjacent communities.
When do ecotones have a sharp boundary?
Resource discontinuous.
What 2 things reflect species diversity?
Species richness and relative abundances of each species.
What kind of animals feed on dead and dying material?
Detritivores
What are used to reflect the trophic structure of a community?
Food webs.
What hypothesis suggest that r and K-selected species can occupy the same habitat under intermediate disturbance?
Intermediate disturbance hypothesis.
Longer growing season in the tropics lead to what?
Greater productivity.
What variable tells the number of species on an island?
Equilibrium number. (Balance between immigration and extinction of species)
