Hello, IGIT, and welcome to EvC!
I don't know if I can find it without asking an internet acquaintence who was involved, but a poll was taken among science faculty in Ohio universities a few years back, during the Discovery Institute's push to get "Intelligent Design" a foothold in their public education system. It came out way over 90% on the side of evolution, but I can't give you details of how the questions were posed. The poll did, as I remember it, include more fields than just the biological sciences.
I'll google a while, and if that fails, I'll ask my cyberfriend.
