Flashcards in Lab 3: Population Growth Model: Exponential Growth Deck (24):
Have fixed values therefore the outcome is fixed.
models are formulated in terms of the probabilities of occurrence of such different events.
Why do populations need to overproduce in order to prevent from going extinct?
In order to recover from catastrophe's. If the population didn't reproduce to replace itself, or just replaced it self they would go extinct.
the ability of a species to produce more offspring than are neccesary to replace the existing population. This define the maximum rate at which a population can grow. (rm).
4 factors of female life history which determine rm are:
1.) The length of time a female reproduces
2.) female age specific survivorship
3.) female birth per female per reproduction.
4.) delay of reproduction (generation time T)
population size at time (t) units: indiviuals
original population size in unit of individuals
time during which population is growing
intrinsic rate of increase (units: individuals/individual/time)
relaized intrinsic rate of increase at a particular point in time.
base of natural log
finite rate of increase or multiplication rate (units: time)
What slows exponential growth?
