Objectives:

1) To maintain and continually update a database of AAD examples, with referenced information on their biogeographic history (including the timing, direction, and mechanism of dispersal), ecology, genetics (including chromosome number), morphology, nomenclature, phylogeny, reproductive biology, and speciation rates;

2) To maintain an annotated bibliography of papers pertinent to the study of AADs;generate robust phylogenies of AAD distributed plant group;

3) To provide an active forum for discussion of AAD organisms;

4) To provide distribution maps of AAD examples;

5) To evaluate common patterns and processes among AAD organisms that may be used to generate hypotheses on aspects of their dispersal and diversification.
