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 answer is that activity density depends not only on the abundance of
competitors, but also on the availability and use of different habitats. In the Negev
Desert, there are two habitat types that the gerbils use. “Semistabilized dunes"
This nonlinear isocline reflects the effects of competition and habitat selection.
The thin lines divide the state space into regions based on habitat use. Region 1:
Both species use the preferred habitat, semistabilized dune. Region 2: G.
Fish that live in lakes, mammals that occupy patches of forested mountaintops,
and insects that visit thistle-heads all show a species—area relationship for their
respective habitat islands. Because a national park or a nature reserve effectively
