Early Humboldtian Influences On Alfred Russel Wallace's Scheme Of Nature [Presented At The Alfred Russel Wallace And His Legacy Royal Society Of London Meeting, 21 October 2013], Charles H. Smith

DLPS Faculty Publications

Alfred Russel Wallace’s 1858 Ternate paper on natural selection is a famous work in the history of science. Beyond his co-discovery of the principle, moreover, Wallace is known for a large number of early applications of the idea, both to biological and biogeographical subjects. Yet how much do we really know about Wallace’s own evolution of thought, and his actual intentions before his views were swallowed up by the inertia of Darwin’s revolution? A number of differences between Wallace’s and Darwin’s views are apparent and have been much treated over the years, but related discussions dwell more on effects than …

Nutritional Capability Of And Substrate Suitability For Pseudogymnoascus Destructans, The Causal Agent Of Bat White-Nose Syndrome, Daniel B. Raudabaugh, Andrew N. Miller

KIP Articles

Pseudogymnoascus destructans, the causal agent of bat white-nose syndrome, has caused nearly six million deaths in North American bats since its introduction into the United States in 2006. Current research has shown that caves can harbor P. destructans even after the infected bats are removed and bats no longer visit or inhabit previously infected caves. Our research focuses on elucidating reservoir requirements by investigating the nutritional capabilities of and substrate suitability requirements for six different P. destructans isolates from various localities including Illinois, Indiana, New York (Type specimen), and Pennsylvania. Enzyme assays implicate that both urease and b-glucosidase appear to …

A Clamped Dual-Ridged Waveguide Measurement System For The Broadband, Nondestructive Characterization Of Sheet Materials, Milo W. Hyde Iv, Michael J. Havrilla

Faculty Publications

A novel two-port probe which uses dual-ridged waveguides for the nondestructive, broadband characterization of sheet materials is presented. The new probe is shown to possess approximately 2 to 3 times the bandwidth of traditional coaxial and rectangular/circular waveguide probe systems while maintaining the structural robustness characteristic of rectangular/circular waveguide probe systems. The theoretical development of the probe is presented, namely, by applying Love’s equivalence theorem and enforcing the continuity of transverse fields at the dual-ridged waveguide apertures, a system of coupled magnetic field integral equations is derived. The system of coupled magnetic field integral equations is solved using the method …

Milnesium Lagniappe, A New Species Of Water Bear (Tardigrada, Eutardigrada, Apochela, Milnesiidae) From The Southern United States, Harry A. Meyer, Juliana G. Hinton, Maria C. Dupré

Western North American Naturalist

Over 200 species of freshwater and terrestrial water bears (phylum Tardigrada) are known to occur in North America. Of these, 20 species have been recorded in Louisiana. Foliose and fruticose lichen and moss samples collected in 2011 in the city of Lake Charles and in Sam Houston Jones State Park, Calcasieu Parish, Louisiana, USA, were stored in paper envelopes and later soaked in tap water overnight. Tardigrade specimens and eggs were extracted and mounted in polyvinyl lactophenol. The samples contained a new species of tardigrade. Milnesium lagniappe sp. n. has claw formula [2-3]-[3-2] and 9 sculptured bands in the dorsal …

Dynamics Of Phytoplankton Distribution In Relation To Stratification And Winter Precipitation, Fallen Leaf Lake, California, Paula J. Noble, Sudeep Chandra, David K. Kreamer

Western North American Naturalist

Seasonal succession and interannual variation of modern diatom populations in Fallen Leaf Lake, Sierra Nevada, California, are characterized and discussed in relation to stratification, water quality, and inflow during spring runoff. Fallen Leaf Lake is a deep, transparent subalpine lake that undergoes a 5–6 month period of stratification and develops a deep chlorophyll maximum (DCM) dominated by diatoms. A seasonal succession was observed, where the early spring was dominated by Asterionella formosa, Fragilaria tenera-group (F. tenera and F. nanana), Tabellaria flocculosa strain IIIp, Aulacoseira subarctica, and Urosolenia eriensis. Asterionella formosa and T. flocculosa strain IIIp persisted …

Distribution And Movement Of Big Spring Spinedace (Lepidomeda Mollispinis Pratensis) In Condor Canyon, Meadow Valley Wash, Nevada, Ian G. Jezorek, Patrick J. Connolly

Western North American Naturalist

Big Spring spinedace (Lepidomeda mollispinis pratensis) is a cyprinid whose entire population occurs within a section of Meadow Valley Wash, Nevada. Other spinedace species have suffered population and range declines (one species is extinct). Managers, concerned about the vulnerability of Big Spring spinedace, have considered habitat restoration actions or translocation, but they have lacked data on distribution or habitat use. Our study occurred in an 8.2-km section of Meadow Valley Wash, including about 7.2 km in Condor Canyon and 0.8 km upstream of the canyon. Big Spring spinedace were present upstream of the currently listed critical habitat, including …

Tolerance Values And Effects Of Selected Environmental Determinants On Caddisfly (Trichoptera) Distribution In Northwest And North Central Washington, Usa, Dean W. Blinn, David E. Ruiter

Western North American Naturalist

Caddisflies were collected at 181 wall seep, stream, river, and lake habitats in 7 counties in northwest and north central Washington over a 6-year period. From 17,405 specimens, we identified 164 adult caddisfly species within 62 genera and 16 families. Twenty taxa were new state records, bringing the number of species currently reported from Washington to 230. Species assemblages were compared to altitude, physicochemical factors, aquatic habitats, and land use (urban, agriculture, and forest) on the west and east sides of the North Cascade Range. Species richness showed significant positive correlations to altitude and pH and showed significant negative correlations …

Factors Influencing Mortality Associated With The Translocation Of Northern River Otters (Lontra Canadensis) In Utah, Casey C. Day, Matthew D. Westover, Brock R. Mcmillan

Western North American Naturalist

Reintroductions and translocations of northern river otters have been a common management practice throughout the United States from the 1970s to the 2000s. Though many reintroductions have been successful, populations are not always monitored or evaluated post-release. From 2009 through 2012, we translocated 27 radio-marked otters into the Provo River watershed in northern Utah. Our objective was to determine what factors influenced the translocation-related mortality of otters. We developed a series of a priori models and used logistic regression to determine the most influential factors. We used Akaike’s information criterion to evaluate relative model support. We found that the univariate …

Microdistributional Variability Of Larval Caddisflies In Mediterranean-Climate Streams In Northern California, Joseph R. Holomuzki, Paula C. Furey, Rex L. Lowe, Mary E. Power

Western North American Naturalist

Knowing how physical and biogenic habitat characteristics affect microspatial variability of larval caddisflies is important to understanding potential population distributions and local species assemblages. We show that larval caddisfly densities and assemblages vary between study reaches and streams on the Angelo Coast Range Reserve in northern California and that species abundance patterns are associated with specific habitat variables. Dicosmoecus gilvipes and Psychoglypha spp. were most dense in 4th-order reaches of the south fork of the Eel River (SFE) and rare or absent in shallow 2nd- and 1st-order reaches of the Elder and Fox Creek tributaries, respectively. Multidimensional scaling (MDS) suggested …

Eastern Fox Squirrel (Sciurus Niger): New Threat To Pecan Orchards In Far West Texas, Jennifer K. Frey, Jaime Iglesias, Krysta Herman

Western North American Naturalist

We report the first records of the eastern fox squirrel (Sciurus niger) in Trans-Pecos Texas. Sciurus niger is widely established in pecan orchards in the Lower El Paso Valley of the Rio Grande, El Paso County. Expansion of this population to other pecan-growing regions along the Rio Grande in New Mexico is possible. Research is needed on both the extent of damage caused by S. niger to pecan production and the control methods in this situation. We recommend a goal of complete eradication of S. niger from this region. Sciurus niger should be delisted as a game species …

Evidence Of Hantavirus Exposure In Rodents From North Texas, Richard M. Pitts, Matthew R. Mauldin, Cody W. Thompson, Jerry R. Choate

Western North American Naturalist

Between 27 June 1997 and 16 May 1999, 423 rodents were collected from North Texas (Collin, Denton, and Grayson counties) by using Sherman live-traps (trapping success rate ~22%). Of the 423 rodents collected, 328 were tested for evidence of IgG antibodies to New World hantaviruses. Hantavirus antibodies were detected in 34 individuals (~10%). This is the first record of hantavirus antibody–positive rodents from the highly urbanized area of North Texas.

Spatial Ecology Of Female Mule Deer In An Area Proposed For Wind Energy Development, Stephen L. Webb, Matthew R. Dzialak, Dean Houchen, Karl L. Kosciuch, Jeffrey B. Winstead

Western North American Naturalist

Development for wind energy is increasing rapidly across the United States, particularly in Wyoming, despite a general lack of information on the potential interaction development could have on wildlife species. Therefore, knowledge of the space use and movement patterns of individuals can help define spatial distributions and management unit boundaries for populations prior to development. Such knowledge can also be used as baseline data from which to assess any future impacts on animal populations. We investigated the spatial ecology of female mule deer (Odocoileus hemionus; n = 18) equipped with global positioning system collars from 23 February 2011 to …

An Assessment Of Permanent And Nonpermanent Plots In Riparian Vegetation Monitoring, Caroline M. Laine, Karin M. Kettenring, Brett B. Roper

Western North American Naturalist

The aim of this research was to determine whether permanent and nonpermanent plots for describing riparian plant communities would yield the same results. This research was conducted at 4 streams in central eastern Idaho. Permanent and nonpermanent greenline plots (first perennial vegetation adjacent to stream) were sampled repeatedly from June to October 2010, and we assessed differences between plot types by comparing species richness, wetland indicator rating, and percent cover of live vegetation, forbs, graminoids, litter/moss, and bare ground. We found few statistically significant differences between permanent and nonpermanent greenline plots. Because both types of plots yielded similar results, we …

Ringtail (Bassariscus Astutus) Noninvasive Survey Methods, Density, And Occupancy In Central New Mexico, Usa, Robert L. Harrison

Western North American Naturalist

I tested 3 hair-collection devices used for population surveys of ringtails (Bassariscus astutus): PVC pipes, modified cage traps, and triangular Coroplast^® tunnels. Coroplast tunnels were the most efficient, with hair obtained by 92% of tunnels tested on radio-collared ringtails. I used the tunnels to survey ringtails on the Sevilleta National Wildlife Refuge in central New Mexico. Probability of detection in areas where ringtails were present was 74% (95% CI 0.56–0.86). Population density was estimated to be 0.17–0.33 ringtails · km^–2 and occupancy (Ψ) by ringtails was 0.56 (95% CI 0.35–0.75).

Pollination Biology Of Astragalus Phoenix (Fabaceae) With Notes On The Natural History Of Its Pollinator, Anthophora Porterae (Hymenoptera: Apidae), David A. Tanner, Catherine Clark, James P. Pitts

Western North American Naturalist

Astragalus (Fabaceae) is a broadly distributed, diverse, and economically important group of plants. Given the number of species and its distribution, it is not surprising that there are many species that are highly restricted and endangered. Among these is the Ash Meadows milkvetch, Astragalus phoenix. Here we investigate the breeding biology of As. phoenix. Our data show that As. phoenix is xenogamous and thatAnthophora porterae (Hymenoptera: Apidae) is the most likely pollinator. We also noticed Apis mellifera visiting As. phoenix, though it appears unlikely that Ap. melliferacontributes significantly to the reproductive success of As. phoenix. We located …

Bobby Fischer In Socio-Cultural Perspective: Application Of Hiller’S (2011) Multi-Layered Chronological Chart Methodology, Jospeh G. Ponterotto, Jason D. Reynolds

The Qualitative Report

This article presents a case study application of Hiller’s (2011) Multi - Layered Chronological Chart (MLCC) methodology to the life story of former World Chess Champion Bobby Fischer. Designed for use in qualitative biographical studies, the MLCC is adapted here for psychobiographical research. In 1972, Fischer became an American Cold War hero as he wrestled the World Chess Championship from a half century of Soviet domination. His rapid rise to world fame was followed by infamy as Fischer abandoned competitive chess, grew increasingly Anti - Semitic and Anti - American, became a fugitive from U.S. justice, and died in relative …

Origins Of Specificity During Tdcs: Anatomical, Activity-Selective, And Input-Bias Mechanisms, Marom Bikson, Asif Rahman

Publications and Research

Transcranial Direct Current Stimulation (tDCS) is investigated for a broad range of neuropsychiatric indications, various rehabilitation applications, and to modulate cognitive performance in diverse tasks. Specificity of tDCS refers broadly to the ability of tDCS to produce precise, as opposed to diffuse, changes in brain function. Practically, specificity of tDCS implies application-specific customization of protocols to maximize desired outcomes and minimize undesired effects. Especially given the simplicity of tDCS and the complexity of brain function, understanding the mechanisms leading to specificity is fundamental to the rational advancement of tDCS. We define the origins of specificity based on anatomical and functional …
