2.2 Flashcards
N
represents pop and is a function of t
t
represents time
dN/dt
represents growth rate
r
maximum per capita growth rate
N o
a constant represents initial pop size
Density-dependent
impact growth as population gets more dense and is generally biotic
Density-independent
major impact no matter what, generally abiotic
Where is population growth highest in an logistic growth model
Before the population reaches the carrying capacity
Where is population growth is highest in an exponential growth model
as the population density increases the growth increases because more organisms can reproduce
exponential growth model
y axis- population size
x axis- time
logistic growth model
y axis- population size
x axis- time
dotted line at K
in an exponential growth model a larger density means
a faster growth rate because more organisms can reproduce
in an exponential growth model larger per capita means
a faster size increase because the maximum growth/reproduction per individual increases
in a logistic growth model a larger r value means
the population will reach the carrying capacity faster because the max reproduction per individual causes the pop to reach the max faster
