Life History Of The Cui-Ui, Chasmistes Cujus Cope, In Pyramid Lake, Nevada: A Review, William F. Sigler, Steven Vigg, Mimi Bres
Life History Of The Cui-Ui, Chasmistes Cujus Cope, In Pyramid Lake, Nevada: A Review, William F. Sigler, Steven Vigg, Mimi Bres
Great Basin Naturalist
The cui-ui, Chasmistes cujus Cope, a member of the sucker family and endemic to Pyramid Lake, Nevada, is listed as endangered by the U.S. Fish and Wildlife Service. Cui-ui was once a major source of sustenance for native Americans, who have inhabited the Lahontan region for at least 11,000 years. The Northern Paiutes developed sophisticated fishing technology to harvest this resource. The original distribution of cui-ui was the ancient Lake Lahontan complex, but as a result of climatic changes it was restricted to the Pyramid–Winnemucca–Truckee system by the turn of the 20th century. Transbasin water diversions (1905 to present) have …
Food Habits And Dietary Overlap Of Nongame Insectivorous Fishes In Flint Creek, Oklahoma, A Western Ozark Foothills Stream, C. Stan Todd, Kenneth W. Stewart
Food Habits And Dietary Overlap Of Nongame Insectivorous Fishes In Flint Creek, Oklahoma, A Western Ozark Foothills Stream, C. Stan Todd, Kenneth W. Stewart
Great Basin Naturalist
Insectivorous fishes were sampled from March, 1983 to February 1984, in Flint Creek, Delaware Co., Oklahoma. There was insignificant habitat segregation between Etheostoma spectabile and E. punctulatum and seasonal habitat partitioning between Cottus carolinae and both darters. Mature E. spectabile ate primarily chironomids and mayflies, whereas juveniles fed primarily on microcrustaceans. Mature E. punctulatum consumed fewer Ephemerella and Leptophlebia than E. spectabile, feeding on Stenonema and other crustaceans. Juvenile E. punctulatum fed mainly on amphipods and mayflies, and juvenile E. spectabile ate primarily microcrustaceans. Cottus carolinae elected primarily mayflies in spring-summer and chironomids in January-February. Coefficients of dietary overlap …
Age, Growth, And Food Habits Of Tui Chub, Gila Bicolor, In Walker Lake, Nevada, James J. Cooper
Age, Growth, And Food Habits Of Tui Chub, Gila Bicolor, In Walker Lake, Nevada, James J. Cooper
Great Basin Naturalist
At Walker Lake, Nevada, tui chub were collected 1975–1977 for analysis of age, growth rate, and food habits. The fork length (FL)–scale radius (SR) relationship was linear and described by the equation FL = 4.44 + 3.17 (SR). Age I, II, III, and IV chub were 116, 176, 218, and 242 mm fork length, respectively. Maximum longevity was six years. The length weight relationship was defined by the log transformed linear equation log weight = -4.65 + 2.93 (log FL). Chub collected from pelagic regions ate mostly zooplankton, whereas chub collected from littoral areas had a diet of zooplankton and …
Presettlement Vegetation Of Part Of Northwestern Moffat County, Colorado, Described From Remnants, William L. Baker, Susan C. Kennedy
Presettlement Vegetation Of Part Of Northwestern Moffat County, Colorado, Described From Remnants, William L. Baker, Susan C. Kennedy
Great Basin Naturalist
A general botanical inventory of a part of northwestern Moffat County, Colorado, resulted in the location of "remnants" of the presettlement vegetation spectrum that are largely unaltered by grazing, logging, or other recent human-related land uses. The 69 samples taken from these remnants were classified into 22 plant associations. Composition, structure, environmental location, geographical range, and response to disturbance are discussed for each association, and a photograph of each is presented. Seven of the 22 associations are apparently restricted to the study area. Restricted associations occur in the more extreme environments of the study area, such as on calcareous substrata …
Tundra Vegetation Of Three Cirque Basins In The Northern San Juan Mountains, Colorado, Mary Lou Rottman, Emily L. Hartman
Tundra Vegetation Of Three Cirque Basins In The Northern San Juan Mountains, Colorado, Mary Lou Rottman, Emily L. Hartman
Great Basin Naturalist
The vegetation of three alpine cirque basins in the northern San Juan Mountains of southwestern Colorado was inventoried and analyzed for the degree of specificity shown by vascular plant communities for certain types of habitats identified as representative of the basins. A total of 197 vascular plant species representing 31 families was inventoried. Growth forms of all species were noted and a growth form spectrum for all of the communities was derived. The caespitose monocot and erect dicot growth forms are the most important growth forms among the community dominants. The most common growth form among all species is the …
