Population Statistics By Autumn Loanzon X- Rizal

Abundance

amazonaws. com Miriadna. com

G = rx. N # of offspring Rate of growth Initial population size

Density

-Number of organism per area Openclipart. org m²

• Population > food = # of deaths > birth rate = produce smaller size of offspring

Population vs. Metapopulation -Certain eco-system -different areas -interbreed and interact - Same species- Dreamstime. com Clipartof. com

Estimating population abundance -Mark-recapture method Mathsmuggle. blogspot. com Countrysideinfo. co. uk

Rare vs. common population - Small proportion of total population -risk of extinction -small populations - 1 or more specific characteristics -small geographical ranges

Irruptive growth • Growth pattern = not constant • Species reproduce>environment capability of support

Stable growth = • Growth rate + relative age distribution CONSTANT • Birth rate = Death rate

Cyclic growth • Variation in size • Happens regularly

Irregular growth • no constant pattern of growth • Chaotic behavior • Poor interactions in system

Environmental factors Vs. Resources
