BIO E105 Lecture Notes - Lecture 32: Metapopulation, Population Ecology, Life Table
Document Summary
How does age structure affect population growth: a population"s age structure the proportion of individuals that are at each possible age has a dramatic influence on the population"s growth over time. Age structure in a woodland herb: the common primrose lives in sunny gaps in shady woodlands, its age structure varies over time. Rapidly growing juveniles dominate populations in sunny new gaps. As trees grow to shade these gaps, the growth of the population declines, leaving mostly adults in the population. Population momentum : because of recent and rapid population growth in developing countries, overall population size will increase dramatically in these nations over the course of your lifetime, part of this increase will be due to increased survivorship. How large is the current human population: currently, the world population is estimated at over 7 billion. Between 1990 and 1995, the worldwide growth rate averaged 1. 46% per year.
