ecology exam I set IV

-environmental stimuli that trigger a behavior
-genetic, physiological, and anatomical mechanisms underlying a behavior

questions that focus on evolutionary significance of a behavior

Fixed action plan is triggered by an external sensory stimulus known as

red belly of the intruding male acts as a sign stimulus that releases aggression in a male stickleback

chasing away other male stickleback, a male decreases the chance that eggs laid in nest territory will be fertilized by another male

young geese observe their mother moving away from them and calling

geese that follow and imprint on their mother receive more care and learn necessary skills, thus have a greater chance of survival

animals movements that are under substantial genetic influence

simple change in activity or turning rate in response to a stimulus
ex. sow bugs becomes more active in dry areas and less active in humid areas

behavior that causes a change in another animal's behavior

reception of and response to signals

5 ways an animal communicates

chemical substance that animals communicate through

type of communication lacewings use
