Abstract
Recent accumulation of large, multi-species databases of plant traits, combined with major advances in our knowledge of phylogenetic relationships among the angiosperms mean that it is now possible to investigate the role of shifts in seed mass, growth form and dispersal syndrome in the radiation of the angiosperms out of the tropics. Approximately 6500 seed masses are now known for species from all around the world (database accumulated during my PhD). The aim of this proposal is to array these seed masses on to the phylogenetic tree of angiosperms to quantify where and when in the history of the angiosperms the major divergences in seed mass occurred. Then it will become possible to assess how closely divergences in seed mass have been associated with divergences in growth form, dispersal mode or latitude, and to investigate the sequence in which shifts in plant traits and distribution have occurred.
