I was enjoying Richard Smith's excellent answer to this question, and wondered:

If you consider the pollen/seed distribution range to be plant locomotion, is there a database that compares these distances across plant taxa, or perhaps a paper that treats these distances as a trait (in a phylogenetic context, for example)? One might assume that in the transition from wind-pollination to animal pollination (or from wind seed dispersal to animal seed dispersal) there is a sacrifice of decreased distance for increased "accuracy", but maybe this isn't the case.

It seems like this information should be around somewhere – it has relevance to evolution, speciation, climate change adaptation, etc.
