Using your data from these mark-recapture studies, estimate the population size. Because the hummingbirds only breed during specific seasons, what is the geometric rate of increase for this population assuming resources have been unlimited?

Solution

to calculate the polpolation size. Use the formula

P = M_iC_i / R_i

Where, Mi = individuals in first capture

Ci= Individuals in second capture

Ri = individuals recaptured

therefore, po[ulation size = {(40*42) +(25*80) + (75*10) + (26*60) + (39*75) + (61*72)} / {(21+20+6+10+15+18)}

= 1680+2000+750+1560+2925+4392 / 90

= 147.855

= 148

part 2: geometric rate of increase

use the formula

rate of increase , r = {(Y₀ / Y_t) ^ (1/5)} -1

= ((244/80)^0.2)-1

= 0.2498 or 24.98% per year
