Final Flashcards
(40 cards)
semelparity
produce all offspring in single reproductive event
K selection
density dependent
upwelling
cold, nutrient rich water replaces hot water
cognitive learning
solve problems
single species approach
save 1 specie will help entire environment (keystone species)
food chains
link trophic levels from producer to carnivores
density
number of organisms in given area or vol.
kin selections
self-sacrifice for your children
type 1 curve
most individuals die late in life
non-associative learning
habitation, simplest form of learning, no reward or punishment (scarecrow)
random
sheep
learned
changed overtime
adiabatic cooling
cooling due to decrease in air pressure at higher elevations
imprinting
period of development when animals develop irreversible patterns (ducks following mother)
indicator species
status confirms the overall health of an ecosystem
population
multiple organisms of same species living together
keystone species
usually not abundant but have strong ecological role
type 3
huge decline in young
ecosystem engineers
dramatically alter their environment
dispersion patterns
clumped, uniform, random
umbrella species
protect them protects many others
dispersal
movement of individuals away from their area of origin
type 2 curve
uniform rate of decline
arid climates are
30 degrees north and south
