Hugues & Hugues (1995) "Small genomes for better flyers"
Nature 377: 391

see also:

Duret, Mouchiroud, Gautier (1995) "Statistical analysis of
vertebrate sequences reveals that long genes are scarce in
GC-rich isochores." J Mol Evol 40: 308-317

where they looked at length of introns in several mammals
and chicken.

hope this helps
