From an ecological view point there are three major ecological ages in any population. These are, pre-reproductive, reproductive and post reproductive. The relative duration of these age groups in proportion to the life span varies greatly with different organisms.
What are characteristics of population ecology?
Within a particular habitat, a population can be characterized by its population size (N), the total number of individuals, and its population density, 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.What is population ecology essay?
Autecology otherwise known as population ecology is a sub-field of ecology that deals with the dynamics of species population and how these species thrive, survival and interact with the environment. It is the study of how the population size of species groups change over time and space.
How important is population ecology?Population ecology has its deepest historic roots, and its richest development, in the study of population growth, regulation, and dynamics, or demography. Human population growth serves as an important model for population ecologists, and is one of the most important environmental issues of the twenty-first century.

Ecology was originally defined in the mid-19th century, when biology was a vastly different discipline than it is today. The original definition is from Ernst Haeckel, who defined ecology as the study of the relationship of organisms with their environment.
