Eco Flashcards
Instinctive falls under
innate
habituation and classic conditioning under
learned
Learning that can only occur during specific interval in animal’s life
imprinting
taste aversion is
classic conditioning
learning not to respond to stimulus
habituation
Chemical serving as communication signal between members animal species
pheromones
Benefits males females offspring
promiscuous
do malemammals lactate
no
social system in which resources and mating opportunities uneuqually distributed within a group
dominane heirarchy
most of workers are sterile, some produce offspfing
eusocial animals
benefits others at expense of individual
altruistic bheavior
Alleles associated with altruism can be advantageous if the expense of rthis behavior to the altruist is outweighed by increases in reproductive success of realties
William Hamilton’s theory of inclusive fitness
when resources are distributed evenly in enviro
random dispersion occurs
births equals deaths
zero population growth
limits pop growth and has greater effect in dense poulations
density dependent limiting factor
arises regardlesss of the population size
independent
R selected is
opportunistic life history
K selected is
equilibrial ife history
favors traits allowing bearers to produce most offspring the most quickly
opportunistic life history
slowly reproducing
equilibrial life historty
Humans are type
I
benefits 1 species, neither helps nor harms the other
commensalism
one species living in another
symbiosis
Directional selection leads to
character displacement
drive weak to extinction
competitive exclusion
insets lay eggs inside another insect
paranoid
2 effects
distance and area effect
