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.

Metapopulation models have also been extended to two-species models of
competitors or predator and prey. In some cases, species may coexist regionally
that cannot coexist locally in closed populations. In other instances, exposing
Instead, it changes the density of the competitor that is necessary to cause
extinction. Consequently, each isocline is rotated up or down, but remains fixed
at the intercept on its own axis. For the predator, the isocline swings up, because

In contrast to the predictions of the Lotka–Volterra model, the isocline for G.
allenbyi is nonlinear, with steep declines at high and low densities of G.
pyramidum, but a shallow slope at intermediate competitor densities. Why isn't
the isocline of ...
