A Primer of Ecology
A Primer of Ecology presents a concise but detailed exposition of the most common mathematical models in population and community ecology. It is intended to demystify ecological models and the mathematics behind them by deriving the models from first principles. The Primer explains in detail basic concepts of exponential and logistic population growth, age-structured demography, metapopulation dynamics, competition, predation, island biogeography, and, in a chapter new to this edition, succession. The book may be used as a self-teaching tutorial by students, as a primary textbook, or as a supplemental text to a general ecology textbook.

Imagine that we have a cohort of individuals that were all born at the same time.
We follow this cohort from birth until all the individuals have died. We keep track
of the number of individuals that have survived to the start of each new year.
To calculate l(x), divide the number of survivors of age x [S(x)] by the size of the
original cohort [S(0)]: Equation 3.1 The first entry in the l(x) column is 1(0). It
represents the survivorship of the cohort to birth. By definition, all individuals in
cohort A group of individuals in a population, all born at the same time, that are
followed until death. A cohort analysis allows us to directly measure the mortality
rates of different ages and to construct the l(x) schedule for the population.

This is a very good introduction to the mathematical models used in population dynamics. The author begins with a simple exponential model of population growth, gradually extends the model to account ... Read full review
