Red Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations. In this paper we describe the history of human impact, natural history aspects of climate, geology, and ecology, and faunal and floral information for key species in the canyon. The role and importance of Research Natural Areas is discussed, particularly with respect to the need to protect Red Butte Canyon—one of the few remaining undisturbed riparian ecosystems in …

We have adapted techniques developed for the extraction of DNA from formalin-fixed, paraffin-imbedded human tissues for use on preserved fish tissues. DNA was successfully extracted and the d-loop region of mitochondrial DNA was amplified with the polymerase chain reaction (PCR). The sequences of the amplified DNA from preserved and modern samples were identical. These techniques were also applied to fin tissue treated with a variety of preservatives. Extraction of DNA from ethyl alcohol and air-dried fin tissues gave yields equivalent to those from frozen tissues. Extraction of DNA from preserved museum specimens of rare or extinct taxa could significantly increase …
