Distributional data are presented for 30 species of New Mexico Plecoptera including 8 species new to the state list. Previously, many of the included species were known from a single location in the state. A revised checklist of 46 confirmed species is presented for the state.

Studies In Nearctic Desert Sand Dune Orthoptera, Part Xv. Eremogeography Of Spaniacris With Bioecological Notes, Ernest R. Tinkham

Great Basin Naturalist

Four decades of the author's records indicate that Spaniacris deserticola (Bruner) is confined within the periphery of the Colorado Desert. It is usually found, near or within a few hundred feet of sea level, marking the shore line of ancient Lake Cahuilla (except for the Dale Lake record). The preferred host plant is Coldenia palmeri growing on the lower fringes of bajadas, with C. plicata on drift sand being second in preference. Spaniacris can tolerate sand and rock temperatures of 60 C. (believed to be a maximum for Colorado Desert life). Mating takes place at that and lower temperatures. When …

Evolution Of The Sceloporine Lizards (Iguanidae), Kenneth R. Larsen, Wilmer W. Tanner

Great Basin Naturalist

Phylogenetic relationships among Sceloporine genera are briefly discussed. Species relationships within the genus Sceloporus are analyzed, and evolutionary lines of descent are proposed. The genus Sceloporus is composed of three monophyletic groups: Group I, the most primitive, probably developed from Sator-like ancestral stock in Miocene times. This group speciated from stock similar to Sceloporus gadoviae in southern Mexico to S. merriami in the North and contains 7 species in 3 species groups. We propose that these species be included in the genus Lysoptychus Cope. Group II arose from Group I and evolved from centrally located Sceloporus pictus in all …

Environmental Factors In Relation To The Salt Content Of Salicornia Pacifica Var. Utahensis, D. J. Hansen, D. J. Weber

Great Basin Naturalist

The stability of the salt content in Salicornia pacifica Standl. var. utahensis (Tidestrom) Munz in relation to environmental changes was investigated. Salicornia pacifica communities have a characteristic soil pH of 7.5 to 8.0 ± 0.2 and a constant subsurface soil moisture level of 25 to 35 percent. The ion content in the tissue of S. pacifica remained constant despite increased moisture stress throughout the growing season. The concentrations of the salts were significantly higher in the surface soil layers than in the subsurface layers around the roots. Normal metabolic processes in the tissues of S. pacifica appear to occur even …

New Synonymy And New Species Of American Bark Beetles (Coleoptera: Scolytidae), Stephen L. Wood

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 …

Water Balance And Fluid Consumption In The Southern Grasshopper Mouse, Onychomys Torridus, Vernon C. Bleich, Orlando A. Schwartz

Great Basin Naturalist

Weight loss was rapid and fluid consumption decreased sharply when Onychomys torridus were exposed to salinities greater than 0.3 Molar. The southern grasshopper mouse is physiologically unspecialized for maintaining water balance in its xeric habitat. The southern grasshopper mouse is capable of weight maintenance on smaller daily water rations than is the northern grasshopper mouse (Onychomys leucogaster). Differences in the water balance of O. torridus and O. leucogaster may influence their local distributions in areas of sympatry.

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 Circular Active Reflector Atenna (Cara), Energy Distribution Calculations, And An Experimental Test, Larry V. Knight, George H. Barry

Faculty Publications

Conventional high-frequency (HF) circular phased arrays, such as the Wullenweber circular array, have a cost factor that increases at a greater-than-square law rate as its radius is increased to produce larger apertures. A new method of forming simultaneous beams in an HF circular array has been proposed in which beams are formed in the space within the array from pickup element energy that has been amplified and reradiated. Such a device is called a circular active reflector antenna (CARA), and its cost increases at a substantially linear rate as its radius is increased to form larger apertures. This paper describes …

Anabaptists Of The Old Bernese State, Delbert L. Graetz

Swiss American Historical Society Newsletter

This presentation will attempt to relate the story of the major religious group in Bernese territory that separated itself from the official state-church, called Taufer and Wiedertaufer by persons outside of their circle since they did not recognize infant baptism and because they baptized adults who might have been baptized earlier as infants. They called each other simply 'Brethren', but in more recent times for official purpos es they have used the name , Alt-evangelische Taufgesinnten. But in cormmon parlance today in Switzerland , they are Taufer to all concerned. Altlough the Emmental and the Oberland have from pre-Reformation times …

Conifer Wood From The Upper Jurassic Of Utah; I, Xenoxylon Morrisonense Sp. Nov., William D. Tidwell, David A. Medlyn

Faculty Publications

A new species of conifer wood, Xenoxylon morrisonense, is described from the Morrison Formation on the Colorado Plateau. It is compared with other species of Xenoxylon, with X. latiporosum being the closest. Xenoxylon morrisonense differs from X. latiporosum in its marked indentations, simple pits on the horizontal and tangential walls of ray cells, absence of crassulae, presence of wood parenchyma, and thin borders on podocarpoid type crossfield pits. The origin of the septa in the tracheids is summarized, and the possible affinity of Xenoxylon with the Podocarpaceae is considered.
