Hi guys. I'm in Ottawa at the American Fisheries Society meeting. There is a poster here on pumpkinseeds and their body morphs. That work talks about four body morphs for pumpkinseeds. One set is flowing water (streamlined) vs. standing water (compressed/saucer). The other split they had was littoral (shallow,nearshore/saucer) vs. open water (streamlined).
Ewest, they cited two papers if you want to try and find them.
Gillespie and Fox 2003, pumpkinseeds morphs, J Fish Biology 62:1099-1115
Bhajat et al. 2006, J Fish Biology 69(C):79-94
Bruce -- after we track down these papers, we can see if they also cite any bluegills papers on body morphs.
Theo, I'm still not sure how they separate condition/feeding from supposed morph.
