The size of the population at each sampling is estimated by
= the estimated population size, ni = the number of lizards caught on the ith 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
Recognize 4 groups in any mark-recapture population:1. animals caught on sampling i and caught at least once before and once
after (Wi), 2. animals not caught on sampling i and caught at least once before and
once after (Xi), 3. animals caught on sampling i and not caught before and/or after (Yi),
and 4. animals not caught on sampling i and not caught before and/or after
(Zi).
Model assumes (Wi / Xi ) ≈ (Yi / Zi ). Model assumes (Wi / Xi ) ≈ (ni / (Ni - ni))(ni / (Ni - ni)) = ratio of # caught and # not caught
To estimate :
Unofficial BME 19.1: using a mark-recapture model to estimate population density
• Rearrange to• If (Wi / Xi ) = (ni / (Ni - ni)), then (Xi / Wi ) = ((Ni - ni)/ni).
• Simplify (Xi / Wi ) = ((Ni - ni)/ni) to (Xi / Wi ) = ((Ni / ni) – 1)
• (Xi / Wi ) = ((Ni / ni) – 1) ((Xi + Wi )/ Wi ) = (Ni / ni).
• Putting together with , & = Wi / (Xi + Wi )
• 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 (Wi), and how many animals were not caught on sampling i and caught at least once before and once after (Xi).

• Only caught animals are used to estimate the population size• Once is known, plug back in to to estimate
