<br />December 1993 <br /> <br />". <br /> <br />sonal feeding ecology of nonnative fIshes in var- <br />ious habitats. <br />This study was funded by the Recovery Im- <br />plementation Program for Endangered Fish Spe- <br />cies in the Upper Colorado River Basin. The <br />revovery program is a joinl effort of the U.S. Fish <br />and Wildlife Service, U.S. Bureau of Reclama- <br />tion, Western Area Power Administration, states <br />of Colorado, Utah, and Wyoming, upper basin <br />water users, and environmental organizations. We <br />thank the U.S. National Park Service for per- <br />mission to work within Dinosaur National Mon- <br />ument. K. Bestgen, J. Bundy, S. Meismer, and <br />M. Williams assisted with fieldwork. G. Haines, <br />C. McAda, D. Snyder, R. Valdez, and two anon- <br />ymous reviewers provided useful comments on <br />earlier drafts of the manuscript. This paper is <br />contribution no. 56 of the Colorado State Uni- <br />versity Larval Fish Laboratory. <br /> <br />.~ <br /> <br />LITERATURE CITED <br /> <br />HAINES, G. B., AND H. M.
