Population size Case study.
Population size Case study. You perform a mark-recapture study to understand the population size of slender salamanders (Batrachoseps attenuates) in Arcata, California. You initially catch and mark 15 individuals. In your second sample, you catch 20 individuals, and zero of them are marked. You estimate the total population size as A. 20 individuals B. 50 […]
