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
