Real Time Network Monitoring And Reporting System, Ricky Lee Massengale Sr.
Theses and Dissertations
With the ability of modern system developers to develop intelligent programs that allows machines to learn, modify and evolve themselves, current trends of reactionary methods to detect and eradicate malicious software code from infected machines is proving to be too costly. Addressing malicious software after an attack is the current methodology and should be a fallback approach. A modern approach should be to perpetually monitor the "enterprise network backbone" traffic and broadcast alerts while taking protective and pre-emptive measures, in the event that the traffic falls out of the bounds of pre-described norms. This work demonstrates that a synergy approach …

New Notiodes Semiaquatic Weevil (Curculionidae) From Sporocarps Of Marsilea Mollis (Marsileaceae) In Southern Arizona, Usa, Charles W. O'Brien
New Notiodes Semiaquatic Weevil (Curculionidae) From Sporocarps Of Marsilea Mollis (Marsileaceae) In Southern Arizona, Usa, Charles W. O'Brien
Western North American Naturalist
A new species from the semiaquatic weevil genus, Notiodes sporocarpicus, which develops and pupates in the sporocarps of the water fern Marsilea mollis B.L. Rob. & Fernald, is described from cattle tanks in southeastern Arizona. This new species can be separated readily from the majority of the known species by its nearly straight rostrum, with its distinctive dorsally swollen base and attenuated apex. Its elongate and slender body will separate N. sporocarpicus from most species in the genus except N. aeratus, which lacks the characters above. The Texas species N. celatus resembles the new species but has strongly developed suberect …

Survey Indicators For Pygmy Rabbits: Temporal Trends Of Burrow Systems And Pellets, Dana M. Sanchez, Janet L. Rachlow, Andrew P. Robinson, Timothy R. Johnson
Western North American Naturalist
Obtaining estimates of absolute abundance for rare or cryptic species can be challenging. In these cases, methods using indirect indicators such as sign might offer useful indices of population size. Pygmy rabbits (Brachylagus idahoensis) are small, burrowing lagomorphs for which methods for population assessment and monitoring are needed. Current tools for estimating relative abundance rely on detecting and assessing fecal pellets and burrow systems. We evaluated temporal changes in each of these indicators to gauge their potential usefulness as indicators of relative and absolute abundance of pygmy rabbits. Pellet persistence was strongly influenced by environmental exposure, and based …
Records Of The Yellow-Nosed Cotton Rat (Sigmodon Ochrognathus) In Southwestern New Mexico, Keith Geluso
Records Of The Yellow-Nosed Cotton Rat (Sigmodon Ochrognathus) In Southwestern New Mexico, Keith Geluso
Western North American Naturalist
The yellow-nosed cotton rat (Sigmodon ochrognathus) previously was known only from extreme southwestern New Mexico in the Peloncillo and Animas mountains. Here I document S. ochrognathus at 3 localities from the Big Burro and Mogollon mountains in southwestern New Mexico. My northernmost capture represents an extra-limital record of 160 km north of prior records in southern New Mexico and represents the northernmost occurrence in North America. Lack of intensive mammalian surveys in the region render it difficult to interpret my recent captures, but the most parsimonious explanation is that captures likely represent overlooked populations. I captured S. ochrognathus …

Arthropod And Plant Communities As Indicators Of Land Rehabilitation Effectiveness In A Semiarid Shrubsteppe, Eric T. Gardner, Val J. Anderson, Robert L. Johnson
Arthropod And Plant Communities As Indicators Of Land Rehabilitation Effectiveness In A Semiarid Shrubsteppe, Eric T. Gardner, Val J. Anderson, Robert L. Johnson
Western North American Naturalist
We describe a case study evaluating the ecological impact of Bromus tectorum L. (cheatgrass) invasion following fire disturbance and the effectiveness of revegetation as a means of rehabilitation in a degraded semiarid shrubsteppe system. The effectiveness of rehabilitation efforts was assessed relative to arthropod richness, vegetation and arthropod community composition, and ground-cover characteristics in 3 habitats: undisturbed, burned and weed infested (B. tectorum), and burned then rehabilitated with native and nonnative vegetation. Arthropods were collected in each habitat using pitfall traps. Differences in arthropod richness were compared using rarefaction curves. Nonmetric multidimensional scaling and nonparametric multivariate statistical procedures, …

Western North American Naturalist
We made 27 collections over nine years at the Clearwater River and conducted preliminary cytogenetic analysis on 232 individuals of the Simulium arcticum complex there. Based on these preliminary findings, we analyzed an additional 1825 larvae from Clearwater collections in 2007, 2008, and 2009 to investigate the reproductive statuses of the two prevalent taxa of the complex there and to determine whether cytogenetic diversity and frequency of types were similar from year to year. We describe a cytotype new to science and a potentially derivative cytotype of S. arcticum sensu stricto. We also determine that these two taxa are present …

Reproductive Cycle Of The Lizard Sceloporus Mucronatus With Comments On Intraspecific Geographic Variation, Maricela Villagrán–Santa Cruz, Oswaldo Hernández-Gallegos, Fausto R. Méndez–De La Cruz
Western North American Naturalist
Sceloporus mucronatus is a viviparous lizard that inhabits high altitudes in central México. Lizards from Tecocomulco, Hidalgo, México, were collected monthly at 2500 m throughout one year. Macro- and microscopic evidence of gonads showed that both sexes reproduce synchronously during the fall. In males, after a short testicular quiescence in December, the recrudescence begins in winter (January) and continues through spring and summer (July), with maximum activity occurring from late summer to early fall (August–September). Regression takes place simultaneously with copulation during the fall (October–November). In females, vitellogenesis occurs during summer and fall (August–November), with ovulation in the fall (November–December). …

The Flight Periodicity, Attack Patterns, And Life History Of Dryocoetes Confusus Swaine (Coleoptera: Curculionidae: Scolytinae), The Western Balsam Bark Beetle, In North Central Colorado, José F. Negrón, John B. Popp
Western North American Naturalist
Dryocoetes confusus Swaine, the western balsam bark beetle, is an important bark beetle associated with Abies lasiocarpa (Hook.) Nutt. (subalpine fir) in western North America. Little information is available on the life cycle and ecology of this insect in Colorado. In this study in north central Colorado, we examined its flight periodicity, attack patterns, and life cycle in downed trees. Flight season, as indicated by pheromone-trap catches, began in early June. Peak flight was observed during early to mid-July. A second peak in flight was observed in some years, but its occurrence was not consistent. Preferred attack sites on downed …

Estimating Root Biomass And Distribution After Fire In A Great Basin Woodland Using Cores And Pits, Benjamin M. Rau, Dale W. Johnson, Jeanne C. Chambers, Robert R. Blank, Annmarie Lucchesi
Western North American Naturalist
Quantifying root biomass is critical to an estimation and understanding of ecosystem net primary production, biomass partitioning, and belowground competition. We compared 2 methods for determining root biomass: a new soil-coring technique and traditional excavation of quantitative pits. We conducted the study in an existing Joint Fire Sciences demonstration area in the central Great Basin. This area is representative of a shrub (sagebrush) ecosystem exhibiting tree (pinyon and juniper) encroachment. The demonstration area had a prescribed burn implemented 4 years prior to our study, and we sampled both control and burned plots. The samples were stratified across 3 microsites (interspace, …

Differential Phytosociological Interactions Involving Male And Female Atriplex Bonnevillensis, Jordan Sinclair, John M. Emlen, Matthew Rinella, Jessica Snelgrove, D. Carl Freeman
Western North American Naturalist
Wind-pollinated dioecious plants often exhibit spatial segregation of the sexes. This partial niche separation has most often been explored using abiotic niche axes. However, if the sexes are truly separated in space, then they are apt to encounter different plant species that may heavily affect growth and reproduction. Also, to the extent that their niches differ, the sexes may respond differently to the same co-occurring species. Here we examine interspecific interactions that influence male and female reproductive potential in Atriplex bonnevillensis. Using Emlen's interaction assessment, a technique which assesses species interactions based on cover classes, we show that Salsola species …
Avian Use Of Harvested Crop Fields In North Dakota During Spring Migration, Alegra M. Galle, George M. Linz, H. Jeffrey Homan, William J. Bleier
Avian Use Of Harvested Crop Fields In North Dakota During Spring Migration, Alegra M. Galle, George M. Linz, H. Jeffrey Homan, William J. Bleier
Western North American Naturalist
Broad-spectrum herbicide applications and improved harvesting efficiency of crops have reduced the availability of weed seeds and waste grains for game and nongame wildlife. Over the last decade, corn and soybean plantings have steadily increased in the Prairie Pothole Region (PPR) of North Dakota, while sunflower plantings have declined. The PPR is an important corridor for migratory birds, and changes in food availabilities at stopover habitats may affect how food resources are used. In early spring 2003 and 2004, we compared bird use of harvested fields of sunflower, soybeans, small grains, and corn in the PPR of North Dakota. Across …
Distribution And Postbreeding Environmental Relationships Of Northern Leopard Frogs (Rana [Lithobates] Pipiens) In Washington, Stephen S. Germaine, Dave W. Hays
Distribution And Postbreeding Environmental Relationships Of Northern Leopard Frogs (Rana [Lithobates] Pipiens) In Washington, Stephen S. Germaine, Dave W. Hays
Western North American Naturalist
Northern leopard frogs (Rana [Lithobates] pipiens) are considered sensitive, threatened, or endangered in all western states and western Canadian provinces. Historically present in eastern Washington in 6 major river drainages, leopard frogs are now only known to occur at 2 localized areas in the Crab Creek drainage in Grant County. During the summers of 2002–2005, we surveyed both areas to document extent of leopard frog distributions and to describe habitat and vertebrate community characteristics associated with leopard frog site occupancy. At Gloyd Seeps, 2 juvenile leopard frogs were observed in a total of 8.2 person-days of …

Controls On Radial Growth Of Mountain Big Sagebrush And Implications For Climate Change, Rebecca E. Poore, Christine A. Lamanna, James J. Ebersole, Brian J. Enquist
Western North American Naturalist
Mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana) covers large areas in arid regions of western North America. Climate-change models predict a decrease in the range of sagebrush, but few studies have examined details of predicted changes on sagebrush growth and the potential impacts of these changes on the community. We analyzed effects of temperature, precipitation, and snow depth on sagebrush annual ring width for 1969 to 2007 in the Gunnison Basin of Colorado. Temperature at all times of year except winter had negative correlations with ring widths; summer temperature had the strongest negative relationship. Ring widths correlated …

Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert
Deliberation Versus Dispute: The Impact Of Argumentative Discourse Goals On Learning And Reasoning In The Science Classroom, Mark Felton, Merce Garcia-Mila, Sandra Gilabert
Faculty Publications
Researchers in science education have converged on the view that argumentation can be an effective intervention for promoting knowledge construction in science classrooms.However, the impact of such interventions may be mediated by individuals’ task goals while arguing. In argumentative discourse, one can distinguish two overlapping but distinct kinds of activity: dispute and deliberation. In dispute the goal is to defend a conclusion by undermining alternatives, whereas in deliberation the goal is to arrive at a conclusion by contrasting alternatives. In this study, we examine the impact of these discourse goals on both content learning and argument quality in science.

Adult Learning Satisfaction And Instructional Perspective In The Foreign Language Classroom, Linda Jo Ryan
Adult Learning Satisfaction And Instructional Perspective In The Foreign Language Classroom, Linda Jo Ryan
Dissertations
Adult education literature suggests that the instructional perspective of the teacher has an important effect on adult satisfaction with learning. In this study, the relationships between instructional perspective, satisfaction with language learning, and certain teacher and student characteristics were investigated. Study participants were adult students enrolled in noncredit foreign language courses offered through a community college’s Continuing Education program and their teachers. Henschke’s Modified Instructional Perspectives Inventory (MIPI) was used to evaluate teacher-reported use of andragogical principles. The MIPI is comprised of seven subscales: Factor 1: Teacher Empathy with Learners, Factor 2: Teacher Trust of Learners, Factor 3: Planning and …

Heat Transfer Performance Of Nanofluids In Facility Heating Applications, Roy T. Strandberg
Heat Transfer Performance Of Nanofluids In Facility Heating Applications, Roy T. Strandberg
Engineering
"Nanofluids are a class of fluids comprised of a base fluid with nanoparticles in a colloidal suspension. These fluids have been shown to exhibit substantially higher thermal conductivity than their corresponding base fluids. Investigation is required to determine if this property may be exploited for the purpose of improving the performance of systems employing liquid heat transfer. Detailed analyses of CuO/60% ethylene glycol and Al₂O₃/60% ethylene glycol nanofluids' heat transfer properties were conducted to determine if they provide a net benefit in commercial facility heating systems. The analyses employed previously developed correlations for nanofluid thermophysical, fluid dynamic and heat transfer …

The Doctor, The Publisher And The Curmudgeon: How Personalities, Politics And The Press Set The Stage For Alaska Statehood, Lynne M. Snifka
Arctic and Northern Studies
"Much has been written about Alaska's struggle for statehood in 1959. But before there was a unified push for statehood, before World War II changed the face of Alaska forever and people such as Bob Atwood, Bill Egan and Bob Bartlett fought the good fight, there was a "perfect storm" of personalities, politics and press coverage that prepared Alaska for what would become its greatest triumph. This thesis examines the lives, motives and politics of Territorial Governor John Troy, Territorial Governor Ernest Gruening and U.S. Secretary of the Interior Harold L. Ickes. Their individual vendettas, drive and quests for power …
