+\Abstract{ This document explains diversity related methods in
+  \pkg{vegan}. The methods are briefly described, and the equations
+  used them are given often in more detail than in their help
+  pages. The methods discussed include common diversity indices and
+  rarefaction, families of diversity indices, species abundance
+  models, species accumulation models and beta diversity, extrapolated
+  richness and probability of being a member of the species pool. The
+  document is still incomplete and does not cover all diversity
+  methods in \pkg{vegan}.}
