Prevalence Of Elaeophora Schneideri And Onchocerca Cervipedis In Mule Deer From Central Utah, Lauritz A. Jensen, Jordan C. Pederson, Ferron L. Andersen Sep 1982

Prevalence Of Elaeophora Schneideri And Onchocerca Cervipedis In Mule Deer From Central Utah, Lauritz A. Jensen, Jordan C. Pederson, Ferron L. Andersen

Great Basin Naturalist

Thirteen of 265 deer (4.9 percent) from central Utah were positive for Elaeophora schneideri, and 180 (67.9 percent) were infected with Onchocerca cervipedis. The rate of infection for E. schneideri and O. cervipedis increased significantly with age of the host (chi-square of 17.5 and 15.5, respectively, p < 0.005). The lack of elaeophorosis in elk from the region is presumably due to the low density of the parasite in mule deer.

Ecomorphology And Habitat Utilization Of Echinocereus Engelmannii And E. Triglochidiatus (Cactaceae) In Southeastern California, Richard I. Yeaton Sep 1982

Ecomorphology And Habitat Utilization Of Echinocereus Engelmannii And E. Triglochidiatus (Cactaceae) In Southeastern California, Richard I. Yeaton

Great Basin Naturalist

The relationship between form and habitat utilization of Echinocereus engelmannii and E. triglochidiatus was studied in southeastern California. The major difference in form is in the density of stems comprising the canopy. These differences in morphology create differences in the daily heat loads of each species. Echinocereus triglochidiatus, with its stems densely packed and in contact with each other over much of their lengths, continues to gain heat internally as the sun sets due to conductance between the stems. In contrast E. engelmannii, with a more open canopy, begins to lose heat as the sun goes down. As a result, …

Species-Habitat Relationships In An Oregon Cold Desert Lizard Community, David F. Werschkul Sep 1982

Species-Habitat Relationships In An Oregon Cold Desert Lizard Community, David F. Werschkul

Great Basin Naturalist

The abundance and diversity of lizards in nine habitat types from Oregon were studied from May through October 1980. Eight species were from eight habitat types. The most common species were Sceloporous occidentalis, Uta stansburiana, Sceloporous graciosus, and Cnemidophorus tigris. Phynosoma douglassi was uncommon and Eumeces skiltonianus was not observed. Temporary streams in nonbasaltic areas were the most productive habitat in terms of lizard abundance but sagebrush areas were the most productive habitat in terms of species diversity. No lizards were recorded from grassland conversion areas. The conflict between a land management policy that emphasizes both vegetation conversion and conservation …

Buccal Floor Of Reptiles, A Summary, Wilmer W. Tanner, David F. Avery Sep 1982

Buccal Floor Of Reptiles, A Summary, Wilmer W. Tanner, David F. Avery

Great Basin Naturalist

A general survey of the information presently available on the osteology and myology of the hyobranchial apparatus. Included in the survey are examples of the hyobranchial skeleton of the major groups of reptiles, including the Chelonia, Crocodilia, Rhynchocephalia, and Squamata. The myology treats the muscles directly associated with the hyoid as well as those associated with the functioning of the apparatus, but not arising or inserted directly on or from the hyoid. The innervation of the hyobranchial apparatus is reviewed and briefly discussed based on the information available in a few major studies. An attempt is made to cite all …

Nest Site Selection In Raptor Communities Of The Eastern Great Basin Desert, Dwight G. Smith, Joseph R. Murphy Sep 1982

Nest Site Selection In Raptor Communities Of The Eastern Great Basin Desert, Dwight G. Smith, Joseph R. Murphy

Great Basin Naturalist

Measures of niche breadth and overlap were used to compare nest site selection in a community of 10 raptor species and the Raven nesting in the eastern Great Basin Desert. Three variables were examined: nest site type, elevation, and exposure. Results suggest a division of component raptor species into relatively abundant core species that show wide niche breadths and uncommon fringe species with narrow niche breadths. Differences in use of each resource are most pronounced along elevation gradient in which three guilds are evident that correspond to raptor species groupings that nest at higher, middle, and lower elevations. Each guild …

Phalacropsis Dispar (Coleoptera: Phalacridae), An Element In The Natural Control Of Native Pine Stem Rust Fungi In The Western United States, David L. Nelson Sep 1982

Phalacropsis Dispar (Coleoptera: Phalacridae), An Element In The Natural Control Of Native Pine Stem Rust Fungi In The Western United States, David L. Nelson

Great Basin Naturalist

Larvae of the phalacrid beetle Phalacropsis dispar (LeConte) consumed aeciospores and the underlying sporogenous mycelium, thereby destroying the aecia of all native western pine stem rust fungi studied. Aecia of the introduced white pine blister rust fungus (Cronartium ribicola) were not found to be infested by the beetle. A close, if not obligate, biosis of the beetle apparently exists with the native rust fungi, and their geographic distributions closely coincide. Laboratory tests and field observations indicate that the beetle completes its life cycle in 30 to 40 days and apparently overwinters as an adult. Quantitative data on aeciospore …

Status Of Introduced Fishes In Certain Spring Systems In Southern Nevada, Walter R. Courtenay Jr., James E. Deacon Sep 1982

Status Of Introduced Fishes In Certain Spring Systems In Southern Nevada, Walter R. Courtenay Jr., James E. Deacon

Great Basin Naturalist

We record eight species of exotic fishes as established, reproducing populations in certain springs in Clark, Lincoln, and Nye counties, Nevada. These include an unidentified species of Hypostomus, Cyprinus carpio, Poecilia mexicana, Poecilia reticulata, a Xiphophorus hybrid, and Cichlasoma nigrofasciatum. Tilapia mariae, established in a spring near the Overton Arm of Lake Mead, and Tilapia zilli, established in a golf course pond in Pahrump Valley, are recorded for the first time from Nevada waters. Though populations of transplanted Gambusia affinis persist, other populations of Poecilia latipinna are apparently no longer extant. Cichlasoma severum, Notemigonus crysoleucas, Poecilia latipinna, and Carassius auratus …

Invertebrate Faunas And Zoogeographic Significance Of Lava Tube Caves Of Arizona And New Mexico, Stewart B. Peck Sep 1982

Invertebrate Faunas And Zoogeographic Significance Of Lava Tube Caves Of Arizona And New Mexico, Stewart B. Peck

Great Basin Naturalist

A field survey in caves near Grants, New Mexico, and Flagstaff, Arizona, found only an exceptionally poor fauna of 14 species with no strong patterns of cave restriction. The faunal poverty is judged to be correlated with and influenced by the similarly impoverished boreal forests in nearby mountains. Species of flightless arthropods, suitable for cave colonization and restricted to cool-moist litter of boreal (Hudsonian-Canadian Life Zone) forests, are apparently not now present in suitable, nearby mountain habitats. They may not have dispersed to all available montane sites from the Southern Rocky Mountains during glacial conditions. Either the forests did not …

The Challenge Of Socialist Thought, Noel B. Reynolds Sep 1982

The Challenge Of Socialist Thought, Noel B. Reynolds

Faculty Publications

This presentation points to socialists’ mistaken assumptions of a malleable and perfectible human nature as an insuperable reason for the inevitable failure of socialist systems. It also points to socialist and liberal dependence on declarations of human rights as ineffective protections for human freedom—protections which can only be maintained in constitutionalist systems with deeper structural safeguards against tyranny.

The Diffusion Thermoeffect In Ternary, Nonelectrolyte Liquid Mixtures, Richard L. Rowley, Gerald Platt, Tevin Vongvanich Aug 1982

The Diffusion Thermoeffect In Ternary, Nonelectrolyte Liquid Mixtures, Richard L. Rowley, Gerald Platt, Tevin Vongvanich

Faculty Publications

Expressions for that portion of the heat flux which is due to composition gradients in multicomponent nonelectrolyte liquid mixtures have been formulated in terms of heats of transport. The resultant thermal energy equation in combination with component mass balance equations constitute coupled partial differential equations descriptive of the diffusion thermoeffect in liquid mixtures. These equations were solved with a double perturbation technique subject to initial and boundary conditions consistent with experimental design conditions considered appropriate for successful measurement of multicomponent heats of transport. Based on the adiabatic type cell, the expected temperature response, dependent on cell variables, experimental conditions, and …

Diffusion Thermoeffect Measurements Of Heats Of Transport In Ternary Liquid Toluene Chlorobenzene Bromobenzene Mixtures At 25°C And 3°C, Richard L. Rowley, Gerald Platt, Tevin Vongvanich Aug 1982

Diffusion Thermoeffect Measurements Of Heats Of Transport In Ternary Liquid Toluene Chlorobenzene Bromobenzene Mixtures At 25°C And 3°C, Richard L. Rowley, Gerald Platt, Tevin Vongvanich

Faculty Publications

Heats of transport in ternary nonelectrolyte liquid mixtures have been directly measured for the first time. Diffusion thermoeffect measurements have been made for ternary mixtures of toluene-chlorobenzene-bromobenzene at 25 degrees and 35 degrees C. A new boundary sharpening technique was used in addition to a liquid gate withdrawal method. Both techniques yield consistent, accurate values of the heat of transport, but the new cell provides versatility in allowable densities and compositions of the initial phases. Heats of transport were obtained by nonlinear least-squares fitting of calculated to experimental temperature differences measured at positions symmetric about the initial diffusional interface. The …

Food Consumption An Distribution: An Overview, Dyaa Abdou, B. Gardner Delworth Aug 1982

Food Consumption An Distribution: An Overview, Dyaa Abdou, B. Gardner Delworth

Faculty Publications

Nearly everyone concedes that Egypt is faced with a serious food problem. The Egyptian agricultural sector is unable to feed the increasing and more affluent population. In 1980, agricultural output was estimated to be increasing by about 2.0 percent annually, whereas the country's annual population growth rate was estimated at about 2.3 percent. If the difference in these growth rates continues, Egypt must increase imports each year just to maintain per capita consumption at the present level [3].
