Estimate population size using a mark-recapture method
-minimum harm on the population
-individuals from a population are captured, marked, and released back into the population within a short period of time
-later, the population is sampled again and in this second sample there will be some marked and some unmarked individuals
mark-recapture method equation (Lincoln-Petersen index)
N=a*n/r
A: # of individuals that are marked and released
n: total number of individuals from second sample (includes marked individuals from first sampling)
R: # of recaptured marked individuals
N: estimated population size
Estimate population size using a removal sampling method and regression equation
-# individuals removed per sampling period plotted on y-axis against # of individuals previously removed plotted on x-axis
-estimated size of the population is then obtained from the point where the line of best-fit through the data points crosses the x-axis
Calculate a Shannon-Wiener index for a community (memorize equation)
H=-s/sigma/i=1pilnpi
S: # species
Pi: proportion of individuals in the ith species
Determine community with the highest or lowest species diversity after calculating Shannon-Wiener indexes
