module 4.2 Flashcards
what is the graph of population size vs time?
what are birth and death rates?
-in a population like that of bacteria, yeast, humans, etc. births and deaths are continuous (there is no specific pulse or season of birth)
-b=the proportion of organisms producing a new individual per unit time (per capita birth rate)
-d= the proportion of individuals dying per unit of time (per capita death rate)
what is the equation for the pattern of population size?
the pattern of population size is continuous function of time
-change in population N over time
what is the rate of change vs the exponential population growth?
what is the limit?
what does it look like when r>0 r=0 r<0?
what are intrinsic rates of population growth?
when a population is small and population density so low that intraspecific competition is near non-existent, s species can grow at a maximum r, called the Malthusian parameter (rm or rmax)
-also known as the intrinsic per capita population growth rate
what are some equations on density dependence?
what is K?
what is the inflection?
what is is K/2?
the logistic model?
