Ch. 12/13 quiz Flashcards
what is the difference in approach b/w the geometric growth equation and the exponential growth equation?
geometric growth models species that reproduce at discrete times
sessile organisms
attached to other organisms
- ex: muscles
what is NOT accounted for in a model that considers age structure?
differences in survival b/w diff ages
which is NOT a density-dependent factor?
temperature
the self-thinning curve is evidence for
negative density dependence
what can the age structure of a population tell us about population fluctuations over time?
it can show times of particular growth or decline in previous years
why are some populations inherently cyclical?
delay between the time of breeding and the birth of the offspring
the probability of extinction due to stochastic processes declines as population size increases because…
stochastic events have a proportionally smaller effect
which is an example of demographic stochasticity?
low fertility
if you were trying to save an endangered species that lived in a meta population, how might you try to increase the proportion of occupied patches?
decrease patch isolation
the rescue effect
refers to the dispersal b/w source and sink populations
