Population Management: The Basics Original Power Point Presentation Created by Andy Harrison Modified by GA Agriculture Education Curriculum Office July 2002
Growth Curve • Think of population management like a bank account • Learn how to use the gain • J – Shaped growth
J – Shaped Growth • Intrinsic of growth rate • Every species has “built in” rate of increase • Each species has evolved reproductive strategies and rates • Assures genetic continuance
Limiting Factors • Two types • Density Independent • Density Dependent
Density Independent • Factors which exert influence uniformly on populations of various sizes • Climate • Example: if a tornado destroys group of animals in area, does not matter how many present
Density Dependent • Factors which exert influence on the population where the numbers of individuals present matters • Diseases and parasites are the best examples • In densely populated areas, spread of disease is much more likely
