Intro to population ecology Life tables, survivorship, & age-sex structure Tools ecologists use to describe the present state of a population and predict its future growth. What is half life? Life tables can be constructed using projections of future mortality rates, but more often they are a snapshot of age-specific mortality rates in the recent past, and do not necessarily purport to be projections. Under the scheme, there are three CPF LIFE plans (Standard, Escalating and Basic) to suit different needs. 8. Tools ecologists use to describe the present state of a population and predict its future growth.
