Students have asked these similar questions
What does the growth rate of 0.7 mean in relation to r=(birth-death)+(immigration-emigration)
What does the growth rate of 1 mean in relation to r=(birth-death)+(immigration-emigration)
What happens to the population when r is greater than 1?
What happens to the the population when r is equal to 1?
What happens to the population when r is less than 1?
Provide and explain the factors that lead to each type of distributions.
In the logistic model of population growth what are N and K and what happens if N>K and explain why. Ho w is the population growth affected if N=K?
The per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates. See attached image
If the death rate decreased, what would happen to the population trajectory for population A?
a) increase faster
b) increase slower
c) decrease faster
d) decrease slower
