PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

arthropod intron statistics somewhat different

I can't reconcile these results, which show the preponderance of eukaryote introns in the 1000s of bases size range, with measures that the preponderance of insect and nematode introns are less than 100 bp.
This table summarizes arthropod intron/exon statistics as of early 2009:

Dipterans like the fruitfly have lost introns compared to other insects and arthropods, making the fruitfly somewhat of an outlier in gene structure.
