The Weberian Osteology Of Three Utah Suckers (Catostomidae), William James Stubbs
The Weberian Osteology Of Three Utah Suckers (Catostomidae), William James Stubbs
Theses and Dissertations
The Weberian mechanisms of three Utah Lake suckers (Catostomidae: Catostominae; Catostomini), Catostomus fecundus Cope and Yarrow, Chasmistes liorus Jordan, and Catostomus ardens Jordan and Gilbert, were examined, described, and compared, and a statistical analysis was made of some of their more important differences. The mechanisms were found to be basically similar to one another and to those of other Catostomini as previously described and/or illustrated. They are individually distinct, but each varies within its own limits, the intraspecific variation being greatest in the wider-ranging Catostomus ardens and least in the seemingly most restricted Catostomus fecundus. From the evidence at hand …
Dermacentor Andersoni And Rocky Mountain Spotted Fever In National Forest Recreational Sites Of Utah, C. Selby Herrin
Dermacentor Andersoni And Rocky Mountain Spotted Fever In National Forest Recreational Sites Of Utah, C. Selby Herrin
Theses and Dissertations
The objectives of this study were to determine (1) the prevalence of adult ticks of Dermacentor andersoni in national forest recreational sites of Utah, and (2) the incidence of spotted fever rickettsia, Rickettsia rickettsii, in the ticks of these areas. With the use of a white flannel cloth, 358 adult D. andersoni (135 males and 223 females) were collected from 48 recreational sites during the spring and summer of 1964. Ticks from each collection were put in pools, preserved in non-fat skim milk at -30° C, and subsequently tested for the presence of spotted fever rickettsia by guinea pig inoculations. …
