Great Basin Naturalist

New synonymy is proposed as follows: Pityokteines Fuchs ( = Orthotomides Wood), Araptus foveifrons (Schedl) ( = interjectus Wood), n. comb., Cryptocarenus seriatus Eggers ( = bolivianus Eggers), Hylastes gracilis LeConte ( = asper Swaine), Procryphalus utahensis Hopkins ( = aceris Hopkins), Scolytodes maurus (Blandford) ( = Hexacolus ellipticus Eggers), Scolytus hermosus Wood (= sylvaticus Bright), Xyleborus adelographus Eichhoff ( = vitiosus Schedl), Xyleborus catulus Blandford ( = intricatus Schedl), Xyleborus nepos Eggers ( = signatus Schedl), Xyleborus titubanter Schedl (= dissidens Wood). The following species and subspecies are named as new to science: Cnesinus electus (Costa Rica), C. pilatus …

Genetics, Environment, And Subspecies Differences: The Case Of Polites Sabuleti (Lepidoptera: Hesperiidae), Arthur M. Shapiro

Great Basin Naturalist

Polites sabuleti is an example of an insect having a univoltine, monophenic high-elevation subspecies and a multivoltine lowland one that produces similar phenotypes only in cold weather. When reared under conditions that induce the warm-weather phenotype in lowland stocks, the montane subspecies P. s. tecumseh continues to produce its usual phenotype, indicating that it has become genetically fixed.

Life History And Ecology Of Megarcys Signata (Plecoptera: Perlodidae), Mill Creek, Wasatch Mountains, Utah, Mary R. Cather, Arden R. Gaufin

Great Basin Naturalist

During an investigation of some of the stoneflies (Plecoptera) of Mill Creek, Wasatch Mountains, Utah, Megarcys signata, a large omnivorous stonefly, was found to have a univoltine life history and a slow seasonal life cycle.

Temperature appears to affect the growth rate of Megarcys signata. Warmer stream temperatures accompany the acceleration of the growth rate, whereas cooler stream temperatures apparently retard the growth rate.

Periods of maximum absolute growth rate correspond with maximum carnivorous feeding from August to September and March to April. Chironomidae, Ephemeroptera, and Plecoptera, in that order, were the most abundant prey in the foreguts. Young nymphs …

The Identity Of Bocourt's Lizard Eumeces Capito 1879, Hobart M. Smith, Rosella B. Smith, Jean Guibé

Great Basin Naturalist

Eumeces capito Boucourt, 1879, is a senior synonym of Eumeces xanthi Günther, 1889. No exception to application of the Law of Priority is recommended in this case. The type locality of E. capito as originally published ("La côte oriental des Etats-Unis") is erroneous. Undoubtedly the correct locality is China, but it is not restricted at present.

The Authorship And Date Of Publication Of Siren Intermedia (Amphibia: Caudata), Hobart M. Smith, Rosella B. Smith, H. Lewis Sawin

Great Basin Naturalist

However "just" it might be to credit LeConte, 1828, with Siren intermedia, both Harlan, 1826 (not 1827 as often cited), and Barnes, 1826, antedate LeConte's proposal of the name. As the earliest, Barnes, 1826, stands credited with it. In analysis of precedent for these conclusions, types of taxonomic plagiarism (calculated vs. innocent, homoplagiarism vs. heteroplagiarism) and the distinctions between nomina nuda and nomina dubia are reviewed, giving examples of each category.

Growth Of Plecoptera (Stonefly) Nymphs At Constant, Abnormally High Temperatures, Joseph M. Branham, Arden R. Gaufin, Robbin L. Traver

Great Basin Naturalist

Six species of Plecoptera were maintained at four different temperatures, which were constant and higher than occurred in the natural habitat, and three species at two different day lengths. Each animal was weighed each day or each week. Weight of two species in the wild was monitored from periodic collection.

The weight of each animal fluctuated rhythmically, changing about five percent every five days. These short-term fluctuations probably resulted from changes in water content. Molting occurred when a peak weight was predicted from the cycle and involved temporary gain of about 20 percent in weight. Growth probably stopped for some …

Use Of Selected Macroinvertebrates As Indicators Of Sedimentation Effects On Huntington River, Utah, Michael Kenneth Reichert

Theses and Dissertations

Benthic macroinvertebrate communities of Huntington River, Emery County, Utah were studied to determine effects of sedimentation from construction of Electric Lake Dam, a state highway, and two bridges. Approximately 900 benthic samples were collected from riffle areas above, in, and below the construction zone from January, 1971 to December, 1973. Two settling basins below construction sites were effective in limiting scouring of downstream communities. Heavy silt deposition was limited to a 1-km stream reach. Number of indicators, density, and biomass were reduced in the construction zone during periods of sediment input. During periods of scouring, density and biomass were reduced; …

A Sociological Profile Of Lds Inmates At Utah State Prison, Robert D. Payne

Theses and Dissertations

The present thesis is a study of 103 LDS inmates at Utah State Prison. It tests the hypothesis that the inmates are more likely to come from non-cohesive homes. In 1959, Dr. Evan T. Peterson completed a study of three thousand 12-18 year old LDS male youths. Out of Dr. Peterson's respondents, 112 sixteen-eighteen year old subjects were selectively drawn to match the inmate sample in terms of fathers' occupation and education. This stratified sample was used as the control group.

The study confirmed the above family environment hypothesis. It found that when compared to the control group, the LDS …

The Significance Of Scale Characters In Evaluation Of The Lizard Genera Gerrhonotus, Elgaria, And Barisia, James W. Waddick, Hobart M. Smith

Great Basin Naturalist

Data taken on external scale characters of 1003 specimens representing nine of the sixteen species of Gerrhonotus sensu Stebbins, 1958, strongly indicate that Tihen's 1949 arrangement of those species in three genera (Gerrhonotus, Elgaria, Barisia) is valid. Misinterpretation of the identity of the head scales in various species of this group has led erroneously to disregard of them as indicators of relationships. Actually the scales are as constant as in most other lizards and seemingly provide firm clues to natural associations.

Revision Of The Plant Genus Geranium In Utah, Glen T. Nebeker

Great Basin Naturalist

Within the state of Utah are seven species of Geranium, two of which are annual. The nature of the caudex and the growth habit have been used to separate the perennial species. These characters are inadequate for separating the species. Better morphological characters, keys, and descriptions are presented.

Field Behavior And Seasonal Activity Of The Rodent Bot Fly, Cuterebra Tenebrosa, In Central Washington (Diptera: Cuterebridae), Craig R. Baird

Great Basin Naturalist

Behavior and activity of the rodent bot fly, Cuterebra tenebrosa Coquillett, was studied at a natural aggregation site in central Washington. Daily flight activity extended from 1700 hr to 2030 hr (PDT) beginning in mid-July of 1970 and 1971. The peak of flight activity, in August, was followed by a decline in activity through September. Male flies aggregated on the vertical faces of basalt cliffs, where they awaited females. Daily activity reached a peak at temperatures of 30–35 C. Eggs were laid in rock crevices without regard to the proximity of Neotoma wood rat hosts. Developing fly pupae were found …

Dominance Relationships Of The Dark Kangaroo Mouse (Microdipodops Megacephalus) And The Little Pocket Mouse (Perognathus Longimembris) In Captivity, Andrew R. Blaustein, Arthur C. Risser Jr.

Great Basin Naturalist

Interspecific interactions between the little pocket mouse (Perognathus longimembris) and the dark kangaroo mouse (Microdipodops megacephalus) were tested in the laboratory. P. longimembris was statistically dominant over M. megacephalus. The dominant-subordinate relationships shown by our laboratory results indicate that interspecific aggression may be one mechanism involved in keeping these sympatric species ecologically separated.

Cinemicrography Of Selected Parasites Of Fishes And Of Free-Living Stages Of Haemonchus Contortus, Stephen Homer Hilton

Theses and Dissertations

Two 16 mm color films were made to help fill a general need for instructional motion pictures in the area of Parasitology. One film "Haemonchus contortus, a Sheep Stomach Worm," deals with a nematode parasite of sheep, showing all stages of its external development and including a time-lapse sequence of the embryonation of the egg. The other film, "Some Parasites of Freshwater Fishes," shows six parasites; Ichthyophthirius multifiliis, Cotylurus erraticus, Dactylogyrus sp., Lernaea cyprinacea, Trichodina sp., and Diplostomum spathaceum for the first time in motion pictures. The films were photographed through a Wild dissecting scope and a Reichert Universal Camera …

The Effects Of Highway Construction On The Fish Populations In The Weber River Near Henefer, Summit County, Utah, Edward James Peters

Theses and Dissertations

Alterations of streams to facilitate highway construction and consumptive water use has become a fisheries management problem. To evaluate the effects of channeling concomitant to construction of Interstate 80 N. near Henefer, Utah, altered and unaltered sections of the Weber River were compared on the basis of fishes censused, population estimates and ordinations. Species compositions in particular areas were influenced by local rheologic conditions. Changes in species composition between samplings at a particular area were caused by fish movements. Data from altered sections, rehabilitated with deflectors and checkdams, were not noticeably different than data from unaltered areas. However, fish movements …
