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.

Variability associated with good and bad years for population growth is known as
environmental stochasticity Imagine that a population is growing exponentially
with a mean r (r ) and a variance in r (a,). We will use this model to predict the ...
Second, the variance of Nt is proportional to both the mean and variance of r.
Populations that are growing rapidly, or have a variable r, fluctuate more than
slow-growing populations or those with a relatively constant r. Finally, if the
variance of ...
variance in population size y^Nj The variability or uncertainty in mean population
size. In a stochastic growth model, the variance in N would reflect the variability in
population size generated by many runs of the model. In many stochastic ...
