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.

Model Presentation and Predictions EXPONENTIAL GROWTH WITH AGE
STRUCTURE In Chapter 1, we represented birth and death rates as single
constants (b and d), which allowed us to easily calculate r for a population with
DESCRIBING POPULATION AGE STRUCTURE Once we have calculated r from
the birth and death schedules, we can forecast the total population size by using
any of the equations for exponential growth from Chapter 1. But we are also ...
However, after about 6 time steps, both populations have converged on the same
age structure—they both have the same relative numbers in each age, with
newborns being most common, and the oldest individuals being most rare.
