2 A flock of starlings Figure UN19.1

3 The black-lipped lizard, its distribution and distribution of habitats on Sri Lanka Figure 19.1

4 Sampling and marking of Calotes nigrilabris lizards in the Sri Lanka cloud forest Table 19.1 Sampling periods Average time between samplings # of marked females # of marked males # of marked juveniles 1928 days15414275

5 Population dynamics of a population of black-lipped lizards in Sri Lanka Figure 19.2

6 Population demographics of Calotes nigrilabris lizards in the Sri Lanka cloud forest Table 19.2 Sampling periods Density (#/ha + s.d.) Sampling periods % males (+ s.d.) % females (+ s.d.) % juveniles (+ s.d.) 17220 + 321946 + 839 + 614 + 5

7 The size of the population at each sampling is estimated by = the estimated population size, n i = the number of lizards caught on the i th sampling (here i can be 2-18 – size cannot be estimated for first or last sampling), and = the estimated proportion of the lizard population caught on day i. Unofficial BME 19.1: using a mark-recapture model to estimate population density

8 Recognize 4 groups in any mark-recapture population: 1.animals caught on sampling i and caught at least once before and once after (W i ), 2.animals not caught on sampling i and caught at least once before and once after (X i ), 3.animals caught on sampling i and not caught before and/or after (Y i ), and 4.animals not caught on sampling i and not caught before and/or after (Z i ). Model assumes (W i / X i ­) ≈ (Y i / Z i ­). Model assumes (W i / X i ­) ≈ (n i / (N i - ­ n i )) (n i / (N i - ­ n i )) = ratio of # caught and # not caught To estimate :

9 Unofficial BME 19.1: using a mark-recapture model to estimate population density Rearrange to If (W i / X i ­) = (n i / (N i - ­ n i )), then (X i / W i ­) = ((N i - ­ n i )/n i ). Simplify (X i / W i ­) = ((N i - ­ n i )/n i ) to (X i / W i ­) = ((N i / n i ) – 1) (X i / W i ­) = ((N i / n i ) – 1)  ((X i + W i ­)/ W i ­) = (N i / n i ). Putting together with, & = W i ­ / (X i + W i ­) The proportion of the population caught on day i is estimated by knowing how many animals were caught on sampling i and caught at least once before and once after (W i ), and how many animals were not caught on sampling i and caught at least once before and once after (X i ).
