If natality is represented by $-B$
If mortality is represented by $-D$
If immigration is represented by $-I$
If emigration is represented by $-E$
If population density is represented by $-N$
Then population density at time $t+1$ is represented by
$N_{t+1}=N_{t}-[(B+I)]-i$
$\left.\left.N_{t+1}=N_{t}+[ \mid B+I\right]\right]-[|D+E|]$
$N_{t+1}=N_{t}+[(B+I)]+[|D+E|]$
$\left.N_{t+1}=N_{t}-[\mid B+I)\right]+[|D+E|]$
Population evolve to maximise their reproductive fitness also called Darwinian fitness with
Verhulst - pearl logistic growth is described by the equation.
Carrying capacity is
What would be the growth rate pattern, when the resources are unlimited ?
When does the growth rate of a population following the logistic model equal zero? The logistic model is given as $dN/dt = rN(1-N/K)$
