Apes ch.8 vocab Flashcards
age structure
proportion of individuals at various age
survivorship curve
show the percentage of members of a population surviving at different ages.
r-selected species
species with a high rate of population increase. have many small offspring that usually dies
k-selected species
competitor
reproduce later in life and have a small number of offspring with long life spans. born large and mature slowly and parents care for them. do wellin competition
opportunist
reproduce and disperse rapidly when conditions are favorable
logistic growth
rapid exponential population growth followed by a steady decrease in population growth then levels
density-dependent factors
competition/predation that affect birth/death rate
density- independent factors
some factors-mostly abiotic and environmetal factors- that can kill members of a population or affect birth rates
intrinsic rate of increase
rate at which population would grow if it had unlimited resources
carrying capacity
max population of a species that a habitat can sustain w/o degrading the habitat
environmental resistance
all factors that act to limit the growth of the population
