Dear arthropod genomicists,

Find here an updated table of gene structure statistics (gene and
exon sizes, counts, etc.) for 7 Arthropod genomes.  Recent
genomes included are Aphid, Daphnia, and Nasonia.  Four of the
species have stats based on EST-validated gene structures.

with distribution plots in arthropod-genestruc-hist.pdf

Notable stats: 
-- loss of 2 introns in dipterans and beetle, with corresponding 
   exon size increases, for a rather constant coding length among arthropods.
-- Daphnia has consistently small introns, others have a subset of large introns.
-- Aphid has the largest gene span due to this subset of large introns.
-- Aphid and Daphnia have somewhat smaller exons, comparable to the Worm.
-- Wasp and Bee are fairly similar.
