A population consists of all of the individuals of a particular species that occur in a particular area and have the potential to interact with one another, and populations fluctuate based on a number of factors: seasonal and yearly changes in the environment, natural disasters such as forest fires and volcanic eruptions, and competition for resources between and within species. The statistical study of population dynamics, demography, uses a series of mathematical tools to investigate how populations respond to changes in their biotic and abiotic environments. Many of these tools were originally designed to study human populations. For example, <emphasis>life tables</emphasis>, which detail the life expectancy of individuals within a population, were initially developed by life insurance companies to set insurance rates.

 <title>Population Size and Density</title>
 <para id="fs-idp53097968">The study of any population usually begins by determining how many individuals of a particular species exist, and how closely associated they are with each other. Within a particular habitat, a population can be characterized by its <emphasis>population size (<emphasis effect="italics">N</emphasis>)</emphasis>, the total number of individuals, and its <emphasis>population density</emphasis>, the number of individuals within a specific area or volume. Population size and density are the two main characteristics used to describe and understand populations. For example, populations with more individuals may be more stable than smaller populations based on their genetic variability, and thus their potential to adapt to the environment. Alternatively, a member of a population with low population density (more spread out in the habitat), might have more difficulty finding a mate to reproduce compared to a population of higher density. As is shown in <link target-id="fig-ch45_01_01"/>, smaller organisms tend to be more densely distributed than larger organisms.</para>
