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.

What factors control births and deaths? The number of births will certainly
depend on population size. For example, a population of 1000 warblers will
produce many more eggs than a population of only 25 birds. If each individual
produces the ...
Consequently, the per capita birth and death rates, b and d, remained constant.
We did explore some models in which b and d fluctuated through time (
environmental stochasticity), but those fluctuations were density-independent; in
Birth rate (b) • K Population size (N) Figure 2.1 Density-dependent birth and
death rates in the logistic model. The graph illustrates how the per capita rates of
birth and death change as a function of crowding. The population reaches a
