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.

A population will neither increase nor decrease when the population growth rate
equals zero (dN/dt = 0). For Equation 1.1, there are only two cases when this is
true. The first is when N = 0. Because of migration, population growth in nature ...
Thus, the immigration rate is the product of the probability of local colonization (p)
and the fraction of unoccupied sites (1-f): I = p(1–f) Expression 4.4 The
immigration rate will equal zero in two cases: first, if the probability of local
colonization is ...
Conversely, if no species are present on the island (S = 0), the extinction rate
must equal zero. Thus, the extinction curve is also a straight line with an intercept
of zero, and a maximum rate of E, which occurs when S = P(Figure 7.4): E - Lls ...
