2. Debate origins Theory sustaining the controversy What to focus in order to solve the problem Papers for discussion

3. Metapopulation models to access species richness in habitat patches. Should refuges always consist of the largest possible single area?

4. Experimentally isolated Red Mangrove forest Species richness of canopy arthropods.

5. Archipelago A supports the idea that a cluster of smaller patches might support more species than a single larger patch.

6. Single large always assumed to be the best strategy. Empirical evidence was showing the value of several small. Which way to go when planning conservation reserves?

7. 1) Species area relationship ‪ S = cA ‬ z ; c=constant; z=slope ‪ log(S) = log(c) + zlog(A) ‬ Larger areas = higher habitat diversity = more species

8. Species area relationship – is that always true?

10. Small patches accumulate species faster than larger patches. Habitat diversity
