The distribution of organisms can be mapped using a transect line and displayed as a kite diagram. 4 of 6 Capture-recapture data can be used to calculate a population size estimate. ______________________ 5 of 6 Capture-recapture data assumes - - No deaths, immigration, emmigration. - Identical sampling methods -survival rates not affected by marking organisms. 6 of 6
