At Fossil Rim Wildlife Center -- on Texas 67 near Glen Rose, 55 miles southwest of Fort Worth -- A&M students are studying how African waterbucks are adjusting to life in a temperate environment.

The public can go to http:// blogs.tamu.edu/hoofstock to not only learn about the study but get instructions on how to participate. Visitors to Fossil Rim can upload their photos and notes to Dr. Hoof Stock's Facebook page on the Internet.

Callling all citizen-scientists to help us collect data.
