Composition Of Forest Stands Used By White-Headed Woodpeckers For Nesting In Washington, Jeffrey M. Kozma Apr 2011

Composition Of Forest Stands Used By White-Headed Woodpeckers For Nesting In Washington, Jeffrey M. Kozma

Western North American Naturalist

In this study, I examined the composition of managed ponderosa pine (Pinus ponderosa) forests used by nesting White-headed Woodpeckers (Picoides albolarvatus) along the eastern slope of the Cascade Range in Washington. I sampled trees and snags using the point-centered quarter method to assess species composition, tree and snag density, and stand basal area in 16 forest stands containing White-headed Woodpecker nests. All stands had a history of timber management and 2 had been burned and salvage-logged. Mean live-tree density (≥10.16 cm dbh) was 182.3 trees · ha–1 (SE = 13.52), mean snag density (≥10.16 cm …

Breeding And Parental Care In The Endangered Tehuantepec Jackrabbit (Lepus Flavigularis), Tamara Rioja, Consuelo Lorenzo, Eduardo Naranjo, Laura Scott, Arturo Carrillo-Reyes Apr 2011

Breeding And Parental Care In The Endangered Tehuantepec Jackrabbit (Lepus Flavigularis), Tamara Rioja, Consuelo Lorenzo, Eduardo Naranjo, Laura Scott, Arturo Carrillo-Reyes

Western North American Naturalist

We documented date and duration of each breeding phase, breeding rate, nursing behavior, parental care, and leveret survival of the Tehuantepec jackrabbit (Lepus flavigularis), a critically endangered lagomorph. Between June 2006 and May 2008, we observed 60 adult radio-collared jackrabbits in Oaxaca, México. Tehuantepec jackrabbits exhibit breeding behaviors 250 days out of the year, with a high-intensity period during the rainy season (May–October). Females give birth to 2 leverets 32 days after copulation. Directly after birth, leverets are put into “beds” or “nests,” which are depressions in the ground covered by prairie grass (Jouvea pilosa). Females …

Exercise Conditioning Decreases Downstream Movement Of Pond-Reared Razorback Suckers Released Into A Stream Environment, Luke A. Avery, David L. Ward, Jane C. Marks Apr 2011

Exercise Conditioning Decreases Downstream Movement Of Pond-Reared Razorback Suckers Released Into A Stream Environment, Luke A. Avery, David L. Ward, Jane C. Marks

Western North American Naturalist

Despite augmentation stocking efforts, wild populations of razorback suckers (Xyrauchen texanus) continue to decline. Endangered razorback suckers are commonly raised in off-channel ponds until maturity (approximately 300 mm TL) and then stocked into the Colorado River or its tributaries. After fish are stocked, they commonly move large distances downstream. We conducted an experiment to determine if downstream dispersal could be reduced through exercise conditioning. Two groups of razorback suckers, exercised and nonexercised, were released into Fossil Creek, Arizona. Prior to release, a subsample from each treatment group was tested in a laboratory flow chamber. Razorback suckers that had …

Canyon Grassland Vegetation Changes Following Fire In Northern Idaho, Corey L. Gucker, Stephen C. Bunting Apr 2011

Canyon Grassland Vegetation Changes Following Fire In Northern Idaho, Corey L. Gucker, Stephen C. Bunting

Western North American Naturalist

Native and nonnative vegetation mosaics are common in western rangelands. If land managers could better predict changes in the abundance of native and nonnative species following disturbances, maintenance of native plant cover and diversity may be improved. In August 2000, during suppression of a wildfire near Lewiston, Idaho, a backing fire burned canyon grassland plots. A previous study had recorded species composition and cover prior to the fire, so we were able to evaluate changes in species composition and abundance on established plots before and after the fire. Overall, summer burning had little effect on the grassland communities. Pseudoroegneria spicata …

Melanism In Endangered Mohave Tui Chub Siphateles Bicolor Mohavensis Snyder 1918 (Cypriniformes: Cyprinidae), Sujan M. Henkanaththegedara, Craig A. Stockwell Apr 2011

Melanism In Endangered Mohave Tui Chub Siphateles Bicolor Mohavensis Snyder 1918 (Cypriniformes: Cyprinidae), Sujan M. Henkanaththegedara, Craig A. Stockwell

Western North American Naturalist

Although melanism has been reported in a wide variety of taxa, the presence of melanic individuals is relatively rare in fishes. Melanism in Mohave tui chub (Siphateles bicolor mohavensis), an endangered endemic of the Mojave Desert in California, is reported from 2 of 4 surveyed populations. The typical body color varies from dark brown to olive brown dorsally and is whitish ventrally; sides are silvery or golden, and fins are pale yellow to dusky red. While conducting population censuses in 2007–2008, we found 4 melanic Mohave tui chubs from 2 of 4 surveyed habitats. Two of 1049 fish …

The Relationships Among Plant Cover, Density, Seed Rain, And Dispersal Of Bromus Tectorum In High-Elevation Populations, Andrew R. Kanarek, Rebecca Hufft Kao Apr 2011

The Relationships Among Plant Cover, Density, Seed Rain, And Dispersal Of Bromus Tectorum In High-Elevation Populations, Andrew R. Kanarek, Rebecca Hufft Kao

Western North American Naturalist

The invasive species Bromus tectorum L. is recognized as one of the most ecologically and economically devastating weeds in the western United States. Although B. tectorumhas been studied extensively, few studies have examined its dispersal and spread. We collected data from sites with B. tectorum in and around Rocky Mountain National Park to quantify the relationships between plant cover/density and seed rain and dispersal distance. Results suggest that there is a positive relationship between density within a patch and local seed rain and that B. tectorum exhibits relatively limited short-distance dispersal (where seeds fell in close proximity to plants …

Aging With Independence And Interaction: An Assisted Living Community, Steven J. Flositz Apr 2011

Aging With Independence And Interaction: An Assisted Living Community, Steven J. Flositz

USF Tampa Graduate Theses and Dissertations

As the U.S. population gets older, there is an increased need for senior housing. However, elderly housing is currently associated with dependence and isolation. There is a great disconnect from the retired community with its surrounding context. Senior housing and nursing homes are becoming more similar to miniature hospitals rather than a residential type. This negative view of nursing homes is becoming clear to the general population. In fact, most seniors fear the idea of living within an aging complex. Also, people generally avoid these places, even while visiting family. Florida is on the frontline for the effects of the …

Neural Pathways And Receptor Mechanisms Mediating Stimulation-Evoked Striatal Dopamine Release: Relevance To Deep Brain Stimulation As A Treatment For Parkinson's Disease, Deranda Brewer Lester Apr 2011

Neural Pathways And Receptor Mechanisms Mediating Stimulation-Evoked Striatal Dopamine Release: Relevance To Deep Brain Stimulation As A Treatment For Parkinson's Disease, Deranda Brewer Lester

Electronic Theses and Dissertations Archive

Dopaminergic neurons of the nigrostriatal dopaminergic system, projecting from the substantia nigra compacta (SNc) to the striatum, serve a critical role in mediating voluntary motor control.Parkinson’s disease is a neurological disorder characterized by progressive degeneration of these dopamine neurons, which leads to dopaminergic deficiencies in the striatum.Reduced striatal dopamine transmission is thought to increase inhibitory basal ganglia output to the thalamus and subsequently reduce excitation of cortical motor areas, resulting in impaired motor functioning.Despite unclear mechanisms, deep brain stimulation (DBS) is an established neurosurgical approach for effectively treating the parkinsonian motor symptoms.Currently the subthalamic nucleus (STN) is the most commonly …

Self-Ordered Search: A Novel Fmri Task To Study Working Memory In Children With Catastrophic Disease, Matthew Alan Scoggins Apr 2011

Self-Ordered Search: A Novel Fmri Task To Study Working Memory In Children With Catastrophic Disease, Matthew Alan Scoggins

Electronic Theses and Dissertations Archive

Children treated for brain tumors are at increased risk for developing cognitive deficits. The self-ordered search (SOS) is a computerized neuropsychological test used to investigate working memory, a cognitive system whose function is integral to many high level cognitive processes. Functional-MRI (fMRI) provides important opportunities to characterize neural correlates of SOSperformance non-invasively. Implementation of the SOStask presents challenges in the unique environment of the MRI scanner. First, SOSrequires participants to select a single stimulus from a set. Second, SOSis a behaviorally driven task that entails variable event timing among participants which complicates group analysis of fMRI data. The work presented …

What All The Fuss Is About Vol. 1, Matthew Cook Apr 2011

What All The Fuss Is About Vol. 1, Matthew Cook

Electronic Theses and Dissertations Archive

“What all the Fuss Is About Vol. 1” is a collection of poems that explores the paradox of what I call autobiographical surrealism. The speaker in the poems, in most cases a poet, is navigating through an absurd and comic terrain that uses, as its main tropes, mundane objects, workaday routines, the play of language itself, and the surprising observations found in the quotidian swirl of urban life.

The Effect Of Games On Engagement And Performance In Intelligent Tutoring Systems, Kyle Brandon Dempsey Apr 2011

The Effect Of Games On Engagement And Performance In Intelligent Tutoring Systems, Kyle Brandon Dempsey

Electronic Theses and Dissertations Archive

The purpose of this dissertation is to assess the relation between game-like elements, individual differences in gameplay, and engagement within an Intelligent Tutoring System (ITS). The current studies examined the incorporation of a game into an existing ITS, iSTART. The game, Self-explanation Showdown (Showdown) added game-like elements into the iSTART practice sessions. Incorporating games was expected to increase engagement while not affecting participants’ overall performance. However, the results of Experiment 1 indicated that game-based practice (Showdown) was more engaging than the non-game-based practice (Coached Practice), but produced lower quality self-explanation performance. The decrease in performance was attributed to the amount …

Chimpanzee Vocal Signaling Points To A Multimodal Origin Of Human Language, Jared P. Taglialatela, Jamie L. Russell, Jennifer A. Schaeffer, William D. Hopkins Apr 2011

Chimpanzee Vocal Signaling Points To A Multimodal Origin Of Human Language, Jared P. Taglialatela, Jamie L. Russell, Jennifer A. Schaeffer, William D. Hopkins

Faculty Articles

The evolutionary origin of human language and its neurobiological foundations has long been the object of intense scientific debate. Although a number of theories have been proposed, one particularly contentious model suggests that human language evolved from a manual gestural communication system in a common ape-human ancestor. Consistent with a gestural origins theory are data indicating that chimpanzees intentionally and referentially communicate via manual gestures, and the production of manual gestures, in conjunction with vocalizations, activates the chimpanzee Broca’s area homologue – a region in the human brain that is critical for the planning and execution of language. However, it …

Minibiotus Acadianus (Eutardigrada: Macrobiotidae), A New Species Of Tardigrada From Southern Louisiana, U.S.A., Harry A. Meyer, Megan N. Domingue Apr 2011

Minibiotus Acadianus (Eutardigrada: Macrobiotidae), A New Species Of Tardigrada From Southern Louisiana, U.S.A., Harry A. Meyer, Megan N. Domingue

Western North American Naturalist

Over 200 species of freshwater and terrestrial water bears (phylum Tardigrada) are known to occur in North America. Of these, 16 species have been collected in Louisiana. Foliose and fruticose lichens collected on 18 April 2010 in Acadia Parish, Louisiana, 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. Minibiotus acadianus sp. n. has a buccal tube with single anterior curvature, 2 macroplacoids and 1 microplacoid. Small gibbosities are present on the fourth pair of legs, in 3 …

Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson Apr 2011

Spatial Organization Of Northern Flying Squirrels, Glaucomys Sabrinus: Territoriality In Females?, Jaya R. Smith, Dirk H. Van Vuren, Douglas A. Kelt, Michael L. Johnson

Western North American Naturalist

We determined home-range overlap among northern flying squirrels (Glaucomys sabrinus) to assess their spatial organization. We found extensive home-range overlap among females, and though this overlap could reflect social behavior, we found no evidence of attraction among females, with only one instance of den-sharing. Instead, our results suggest that females share foraging areas but may be territorial in portions of the home range, especially around den trees and during young-rearing. Home-range overlap could also result from the extrinsic effect of forest fragmentation due to timber harvest, which might impede dispersal and force squirrels to cluster on remaining fragments …

Occurrence Of Ord's Kangaroo Rat (Dipodomys Ordii) Along Its Eastern Distributional Limit In Nebraska, Greg D. Wright, Keith Geluso Apr 2011

Occurrence Of Ord's Kangaroo Rat (Dipodomys Ordii) Along Its Eastern Distributional Limit In Nebraska, Greg D. Wright, Keith Geluso

Western North American Naturalist

Changes in land use continue to alter habitats throughout Nebraska, and few studies have examined how such changes affect distributional limits of mammals. The distribution of Ord’s kangaroo rat (Dipodomys ordii) was last examined in eastern Nebraska about 4 decades ago. We examined the current eastern distributional limits ofD. ordii to see whether its range had expanded, contracted, or remained constant in the state since the 1960s. Based on our study, kangaroo rats have experienced little change in distribution during recent decades. Herein, we report on data for 8 counties without prior records and a marginal range …

Simultaneously Hermaphroditic Shrimp Use Lipophilic Cuticular Hydrocarbons As Contact Sex Pheromones, Dong Zhang, John A. Terschak, Maggy A. Harley, Junda Lin, Jörg D. Hardege

Ocean Engineering and Marine Sciences Faculty Publications

Successful mating is essentially a consequence of making the right choices at the correct time. Animals use specific strategies to gain information about a potential mate, which is then applied to decision-making processes. Amongst the many informative signals, odor cues such as sex pheromones play important ecological roles in coordinating mating behavior, enabling mate and kin recognition, qualifying mate choice, and preventing gene exchange among individuals from different populations and species. Despite overwhelming behavioral evidence, the chemical identity of most cues used in aquatic organisms remains unknown and their impact and omnipresence have not been fully recognized. In many crustaceans, …

Socially Adjustable Morality: A Neo-Functional Account, Melvyn L. Fein Apr 2011

Socially Adjustable Morality: A Neo-Functional Account, Melvyn L. Fein

The Journal of Public and Professional Sociology

Morality has always been contentious. Thus, in recent years, absolutists have been aligned against relativists. Both sides, however, are mistaken about the nature of morality. Absolutists come in many varieties, which include: the religious, the naturalist, the philosophical, the Marxist, and the scientific. Meanwhile, relativists are divided into social and individual camps. Opposed to both groups are the moral nihilists who may be classified as nice, nasty, and skeptical. Sadly, all miss the mark because they do not account for morality as it actually operates. A "socially adjustable" model fits the facts much better. It describes morality as consisting of …

Understanding Client Imagery In Art Therapy, Erica K.M. Curtis Apr 2011

Understanding Client Imagery In Art Therapy, Erica K.M. Curtis

Journal of Clinical Art Therapy

This study offers a preliminary investigation into the question: How do art therapists make meaning from viewing client-made art? Art therapy literature on making meaning from client art is reviewed. The Visual Thinking Strategies (VTS) model used in art education and museum education is also briefly discussed for its parallels to this study’s findings. An adapted form of grounded theory for data collection and analysis was used, leading to emergent themes that suggest that understanding client art requires more than analyzing content and aesthetic elements. More specifically, this inquiry offers the consideration that viewing client art is a dynamic practice …

The Adaptive Significance Of Vocal Performance In Songbird Communication, Adrienne L. Dubois Apr 2011

The Adaptive Significance Of Vocal Performance In Songbird Communication, Adrienne L. Dubois

Open Access Dissertations

The question of how honesty is maintained in animal communication is a perplexing one, especially in the context of aggressive communication, in which the interests of signalers and receivers are opposed. Relevant information for receivers in aggressive interactions includes the fighting ability of the signaler and its likelihood of attack. Signalers may, however, benefit from manipulation of signals to exaggerate this information. To address questions of signal honesty, this dissertation investigates the use of a performance signal in the song of swamp sparrows (Melospiza georgiana). Performance signals are ones that are physically demanding to perform and that therefore reveal the …

The Role Of Oxygen During In Vitro Culture And Immunoisolation Of Islets Of Langerhans, Christopher A. Fraker Apr 2011

The Role Of Oxygen During In Vitro Culture And Immunoisolation Of Islets Of Langerhans, Christopher A. Fraker

Open Access Dissertations

While clinical transplantation of islets of Langerhans for the treatment of insulin dependent Diabetes Mellitus has shown significant promise in recent years, there remains a need for procedural optimizations to improve cell viability, functionality and ultimately, graft longevity. One of the most critical factors to islet cell survival is the proper oxygenation of these highly metabolic cellular aggregates. In culture, islets experience suboptimal oxygen profiles delimited by steep gradients across culture media. When retransplanted, they are subjected to extremes of hypoxia and anoxia, resulting in pronounced graft dysfunction and cell loss, which is further exacerbated when these cells are immunoisolated …
