YOU NEED A CALCULATOR!!!!!Start-Up: What is the biological level smaller than a community? How is it defined?

Characteristics of Populations
Population – group of individuals of a single species that live in the

challenges
Population size = total number of individuals
Population density= number per unit area

Sampling Techniques to Estimate Population Density & Size
1. Quadrats
2. Indirect Counting

3. Mark-recapture method
Total population = (# in first capture)(# in second capture) # of marked animals recaptured
