  1. Integrating Concepts in Biology PowerPoint Slides for Chapter 19: Emergent Properties at the Population Level by A. Malcolm Campbell, Laurie J. Heyer, and Chris Paradise

  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 Calotesnigrilabrislizards in the Sri Lanka cloud forest Table 19.1

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

  6. Population demographics of Calotesnigrilabrislizards in the Sri Lanka cloud forest Table 19.2

  7. Unofficial BME 19.1: using a mark-recapture model to estimate population density 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.

  8. Unofficial BME 19.1: using a mark-recapture model to estimate population density To estimate : Recognize 4 groups in any mark-recapture population: • animals caught on sampling i and caught at least once before and once after (Wi), • animals not caught on sampling i and caught at least once before and once after (Xi), • animals caught on sampling i and not caught before and/or after (Yi), and • 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

  9. 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).

  10. Unofficial BME 19.1: using a mark-recapture model to estimate population density • Only caught animals are used to estimate the population size • Once is known, plug back in to to estimate
