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.

Constant b and d. If a population is going to grow with constant birth and death
rates, an unlimited supply of space, food and other resources must be available.
Otherwise, the birth rate will decrease and/or the death rate will increase as ...
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
In the simple exponential model, we assumed that b and d were constant—they
did not vary with time or with population density. In the agestructured model, we
assume that the lsix) and the b(x) schedules are constant. As before, if each age
