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.

The key change is that the entries in the population matrix no longer represent
the age of an organism, but rather its stage (or size). We still incorporate a time
step that represents the transition from one stage to the next. For example, here is
As illustrated in Figure 3.4, these complex life cycles can also be represented in
loop diagrams. Each circle in the loop represents a different life history stage, and
each arrow represents a transition from one stage to the next. Stages not ...
We can understand these equations much better by using the state space, a
special kind of graph. In the state-space graph, the x axis represents the
abundance of species 1, and the y axis represents the abundance of species 2.
This graph ...
