Growth Rates Of The Mediterranean Gecko, Hemidactylus Turcicus, In Southwestern Louisiana, Mark A. Paulissen, Harry A. Meyer, Tabatha S. Hibbs

Western North American Naturalist

We captured and marked Mediterranean geckos, Hemidactylus turcicus, occupying a one-story building in southwestern Louisiana in 1999–2000 and 2002–2005 and calculated 2 estimates of growth rate: length growth rate (difference in snout–vent length [SVL] between captures divided by time between captures) and mass growth rate (difference in gecko mass between captures divided by time between captures). Both length growth rate and mass growth rate were significantly negatively correlated with gecko snout–vent length. When data from all years were combined, adult female geckos showed greater mean length growth rates and mean mass growth rates than males, but the trend was not …

Ecological Adaptation Of The Endemic Shepherdia Rotundifolia To Conditions In Its Colorado Plateau Range, Chalita Sriladda, Roger Kjelgren, Heidi Kratsch, Thomas Monaco, Steven Larson, Fenann Shen

Western North American Naturalist

Due to limited water supplies, use of drought-tolerant species to conserve water in irrigated urban landscapes is increasingly important in the Intermountain West. The Colorado Plateau endemic shrub Shepherdia rotundifolia Parry is a potential candidate for use in sustainable urban low-water landscapes (LWLs) for its aesthetic and drought-tolerant qualities. However, the species is difficult to establish in urban landscapes of different fertility and water availability than found in regional native habitats. A better understanding of environmental and genetic constraints, as well as morphological adaptation in native habitats, may facilitate greater use of S. rotundifolia in LWLs. The goal of this …

Diet Of A Cryptic But Widespread Invader, The Oriental Weatherfish (Misgurnus Anguillicaudatus) In Idaho, Usa, Alexander N. Urquhart, Peter Koetsier

Western North American Naturalist

The oriental weatherfish (Misgurnus anguillicaudatus) is invasive to 13 U.S. states and at least 9 other countries. Although this cryptic fish species is widespread, very little is known regarding its ecology. We used baited minnow traps to collect 237 individuals from water bodies connected to the Boise River, Idaho. To determine the diet of the fish within this invasive population, we dissected and examined stomach contents of the sampled fish. Most of the stomachs (158 of 237) were empty, and 42 contained only the trap bait. However, 37 contained natural food items. Gravimetric analysis, frequency of occurrence, and …

Presence Of The Exotic Weevil (Rhinocyllus Conicus Fröelich) At High Elevations In The Rocky Mountains Of Colorado, Julia J. Hicks, Susan W. Beatty, Timothy R. Seastedt

Western North American Naturalist

We examined the presence of the exotic weevil Rhinocyllus conicus Fröelich on native thistles at high elevations in the Rocky Mountains of Colorado. We tested whether the distribution of R. conicus was related to elevation by performing 2 separate studies. First, transects along an elevation gradient were sampled in Rocky Mountain National Park and presence/absence of R. conicus was scored to infer relationships between environmental variables and weevil occurrence. Second, an experiment was conducted on Niwot Ridge to determine whether weevils were able to complete their reproductive cycle and overwinter at an elevation where they do not currently exist. Results …

Investigation Of Factors Affecting Black-Footed Ferret Litter Size, Christopher R. Ayers, Jerrold L. Belant, David A. Eads, David S. Jachowski, Joshua J. Millspaugh

Western North American Naturalist

Understanding factors that influence recruitment can improve wildlife conservation. Endangered black-footed ferrets (Mustela nigripes) rely on prairie dogs (Cynomys spp.) for food and on prairie dog burrows for shelter. We hypothesized that younger female ferrets with greater densities of prairie dogs in their core use area and fewer adult ferrets in their respective prairie dog colony, would produce more kits due to age-dependent productivity, increased food resources, and decreased competition. We used generalized linear mixed-effects regression and Akaike’s information criterion adjusted for sample size (AICc) to rank models relating adult female black-footed ferret litter size …

Diet Of The Exotic American Bullfrog, Lithobates Catesbeianus, In A Stream Of Northwestern Baja California, Mexico, Liliana Ortíz-Serrato, Gorgonio Ruiz-Campos, Jorge H. Valdez-Villavicencio

Western North American Naturalist

We studied the diet of the exotic American bullfrog (Lithobates catesbeianus) in Arroyo San Carlos, located in northwestern Baja California, Mexico, during spring and summer 2009. Analysis of 64 stomach contents revealed 15 prey types, of which the exotic red crayfish (Procambarus clarkii) and terrestrial isopods (Armadillidiidae) were the most significant items (according to an index of their relative importance), making up 64% and 31% of the bullfrog’s diet, respectively. Diet differed between the sexes, with red crayfish eaten more frequently by males (84%) than females (69%). Bullfrog diet changed with body size, with smaller individuals …

Within-Season Nest Reuse By Mountain Plovers (Charadrius Montanus) In Eastern Colorado, Lani T. Stinson, Victoria J. Dreitz

Western North American Naturalist

The Mountain Plover (Charadrius montanus) is a declining migratory shorebird that nests on shortgrass prairies across the western Great Plains. This ground-nesting species exhibits an uncommon split-clutch mating system, in which each member of a pair simultaneously incubates a nest and uniparental care continues throughout brood-rearing. We report on an observation of within-season nest reuse in this species. To our knowledge, this report includes the first documented occurrence of 2 different Mountain Plovers using the same nest cup in the same breeding season. Nest reuse could represent a time- and energy-saving strategy for renesting individuals.

Multiple Glycosaminoglycan-Binding Epitopes Of Monocyte Chemoattractant Protein-3/Ccl7 Enable It To Function As A Non-Oligomerizing Chemokine, Janna G. Kiselar, Sayan Gupta, Mark R. Chance

Faculty Scholarship

The interaction of chemokines with glycosaminoglycans (GAGs) facilitates the formation of localized chemokine gradients that provide directional signals for migrating cells. In this study, we set out to understand the structural basis and impact of the differing oligomerization propensities of the chemokines monocyte chemoattractant protein (MCP)-1/CCL2 and MCP- 3/CCL7 on their ability to bind GAGs. These chemokines provide a unique comparison set because CCL2 oligomerizes and oligomerization is required for its full in vivo activity, whereas CCL7 functions as a monomer. To identify the GAG-binding determinants of CCL7, an unbiased hydroxyl radical footprinting approach was employed, followed by a focused …

Joy As Illumination: Participation In God's Life-Giving Trinitarian Love, Trevor Beach Sj

School of Theology and Seminary Graduate Papers/Theses

This graduate paper is on the topic of joy, especially as understood in the commentaries of Adrienne von Speyr, and the writings of Hans Urs von Balthasar. In this paper, I show Christian joy as participation in God’s own joy through an illuminated and inter-personal life-giving love as given through and shown in the entire life of Jesus Christ, from the Incarnation, through the suffering Passion, and unto the Resurrection.

Circulating Tumor Cells In Metastatic Breast Cancer: A Prognostic And Predictive Marker, Sayyed Farshid Moussavi-Harami, Kari B. Wisinski, David J. Beebe

Journal of Patient-Centered Research and Reviews

The role of circulating tumor cells (CTCs) as a marker for disease progression in metastatic cancer is controversial. The current review will serve to summarize the evidence on CTCs as a marker of disease progression in patients with metastatic breast cancer. The immunohistochemistry (IHC)-based CellSearch^® is the only FDA-approved isolation technique for quantifying CTCs in patients with metastatic breast cancer. We searched PubMed and Web of Knowledge for clinical studies that assessed the prognostic and predictive value of CTCs using IHC-based isolation.

The patient outcomes reported include median and Cox-proportional hazard ratios for overall survival (OS) and progression-free survival …

Apparent Adoption Of Orphaned Cougars (Puma Concolor) In Northwestern Wyoming, Travis D. Bartnick, Marilyn Cuthill, Derek Craighead, Howard B. Quigley

Western North American Naturalist

Cougars (Puma concolor) are widely distributed throughout the western portion of North America and are generally described as solitary carnivores. Most cougar social interactions have been described as instances of parental care, intraspecific strife, or breeding. We report an apparent case of an adoption of orphaned juveniles in a wild cougar population. We used radiotelemetry and direct visual observations to document an adult female, her 3 dependent offspring, and 2 orphaned juvenile males physically interacting, sharing bed sites, and sharing kills in the late winter of 2007/2008. We consider the potential benefits and/or negative effects of these social …

Temporal Variations In The Abundance And Composition Of Biofilm Communities Colonizing Drinking Water Distribution Pipes, John J. Kelly, Nicole Minalt, Alessandro Culotti, Marsha Pryor, Aaron Packman

Biology: Faculty Publications and Other Works

Pipes that transport drinking water through municipal drinking water distribution systems (DWDS) are challenging habitats for microorganisms. Distribution networks are dark, oligotrophic and contain disinfectants; yet microbes frequently form biofilms attached to interior surfaces of DWDS pipes. Relatively little is known about the species composition and ecology of these biofilms due to challenges associated with sample acquisition from actual DWDS. We report the analysis of biofilms from five pipe samples collected from the same region of a DWDS in Florida, USA, over an 18 month period between February 2011 and August 2012. The bacterial abundance and composition of biofilm communities …

Managing Carbon, Kenneth E. Skog, Duncan C. Mckinley, Richard A. Birdsey, Sarah J. Hines, Christopher W. Woodall, Elizabeth D. Reinhardt, James M. Vose

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Storing carbon (C) and offsetting carbon dioxide (CO2) emissions with the use of wood for energy, both of which slow emissions of CO2 into the atmosphere, present significant challenges for forest management (IPCC 2001). In the United States, there has been a net increase in C in forests and in harvested wood products stocks (Tables 7.1 and 7.2), a result of historical and recent ecological conditions, management practices, and use of forest products (Birdsey et al. 2006). However, recent projections for the forest sector suggest that annual C storage could begin to decline, and U.S. forests could become a net …

Cognitive Mechanisms Of Anger Regulation: The Role Of Executive Function, Katherine G. Denny

Open Access Dissertations

Anger is a prevalent and powerful emotion, arising when another person has thwarted a self-relevant goal or event, and increased effort is required for goal achievement. While the majority of research indicates that anger is an affective precursor to aggression, recent research implies that anger may also have beneficial consequences – at least for some people in some situations. With the negative cost of anger often being severe, and yet the potential that anger utilization can lead to enhanced performance, it is important to understand individual differences in the ability to regulate and utilize anger. To explore this area of …

Octopamine Neuromodulation Regulates Gr32a-Linked Aggression And Courtship Pathways In Drosophila Males, Jonathan C. Andrews, Maria Paz Fernàndez, Qin Yu, Gregory Patrick Leary, Adelaine K. W. Leung, Michael P. Kavanaugh, Edward A. Kravitz, Sarah J. Certel

Biological Sciences Faculty Publications

Chemosensory pheromonal information regulates aggression and reproduction in many species, but how pheromonal signals are transduced to reliably produce behavior is not well understood. Here we demonstrate that the pheromonal signals detected by Gr32a-expressing chemosensory neurons to enhance male aggression are filtered through octopamine (OA, invertebrate equivalent of norepinephrine) neurons. Using behavioral assays, we find males lacking both octopamine and Gr32a gustatory receptors exhibit parallel delays in the onset of aggression and reductions in aggression. Physiological and anatomical experiments identify Gr32a to octopamine neuron synaptic and functional connections in the suboesophageal ganglion. Refining the Gr32a-expressing population indicates that mouth Gr32a …

Implications Of The Landauer Limit For Quantum Logic, F. Matthew Mihelic

Faculty Publications

The design of any system of quantum logic must take into account the implications of the Landauer limit for logical bits. Useful computation implies a deterministic outcome, and so any system of quantum computation must produce a final deterministic outcome, which in a quantum computer requires a quantum decision that produces a deterministic qubit. All information is physical, and any bit of information can be considered to exist in a physicality represented as a decision between the two wells of a double well potential in which the energy barrier between the two wells must be greater than kT·ln2. Any proposed …

A Method To Make A Craniotomy On The Ventral Skull Of Neonate Rodents, Adrián Rodríguez-Contreras, Lingyan Shi, Bingmei M. Fu

Publications and Research

The use of a craniotomy for in vivo experiments provides an opportunity to investigate the dynamics of diverse cellular processes in the mammalian brain in adulthood and during development. Although most in vivo approaches use a craniotomy to study brain regions located on the dorsal side, brainstem regions such as the pons, located on the ventral side remain relatively understudied. The main goal of this protocol is to facilitate access to ventral brainstem structures so that they can be studied in vivo using electrophysiological and imaging methods. This approach allows study of structural changes in long-range axons, patterns of electrical …

Data Figure 3 In "Insights From The Application Of Genetics On Pocillopora-Symbiodinium Associations In The Eastern Tropical Pacific.", Jorge Pinzon

Biology Datasets - Archive

Supporting data for the chapter entitled: "Insights from the application of genetics on Pocillopora-Symbiodinium associations in the eastern tropical Pacific."

As one of the most widely distributed and most studied scleractinian genera in the world, Pocillopora encompasses an important group of corals. In the eastern tropical Pacific, Pocillopora species thrive and are the major reef-building scleractinian taxon, even though conditions are considered suboptimal for coral growth and reef development. Early observations on reproduction and species distributions appear to be complicated by high phenotypic diversity and often inaccurate species identifications. New genetic-based evidence reorganizes species classifications within Pocillopora by delimiting boundaries …
