A Primer of Ecology
With the aim of teaching students the essential models in population and community ecology, this book explains in detail the basic concepts of exponential and logistic population growth, age-structured demography, metapopulation dynamics, competition, predation and island biogeography.

is continuous turnover of individual populations through colonization and
extinction. The fraction of population sites (f) reaches an equilibrium when the
immigration rate precisely equals the extinction rate. We will see this same
derivation once ...
Now we turn to the extinction rate, pus. We expect Hs to increase with increasing
S: the more species present on the island, the greater the rate at which species
disappear. This relationship occurs because each species has a constant ...
Graphically, this equilibrium species number corresponds to the point on the x
axis beneath the intersection of the immigration and extinction curves (Figure 7.5)
. At the intersection, the rate at which new species arrive is matched by the rate at
