Oroya Fever And Verruga Peruana: Bartonelloses Unique To South America, Michael F. Minnick, Burt E. Anderson, Amorce Lima, James M. Battisti, Phillip G. Lawyer, Richard J. Birtles

Biological Sciences Faculty Publications

Bartonella bacilliformis is the bacterial agent of Carrión's disease and is presumed to be transmitted between humans by phlebotomine sand flies. Carrión's disease is endemic to high-altitude valleys of the South American Andes, and the first reported outbreak (1871) resulted in over 4,000 casualties. Since then, numerous outbreaks have been documented in endemic regions, and over the last two decades, outbreaks have occurred at atypical elevations, strongly suggesting that the area of endemicity is expanding. Approximately 1.7 million South Americans are estimated to be at risk in an area covering roughly 145,000 km2 of Ecuador, Colombia, and Peru. Although disease …

Granivory Of Invasive, Naturalized, And Native Plants In Communities Differentially Susceptible To Invasion, B. M. Connolly, Dean Pearson, R. N. Mack

Biological Sciences Faculty Publications

Seed predation is an important biotic filter that can influence abundance and spatial distributions of native species through differential effects on recruitment. This filter may also influence the relative abundance of nonnative plants within habitats and the communities’ susceptibility to invasion via differences in granivore identity, abundance, and food preference. We evaluated the effect of postdispersal seed predators on the establishment of invasive, naturalized, and native species within and between adjacent forest and steppe communities of eastern Washington, USA that differ in severity of plant invasion. Seed removal from trays placed within guild-specific exclosures revealed that small mammals were the …

Identification Of Novel Small Rnas And Characterization Of The 6s Rna Of Coxiella Burnetii, Indu Warrier, Linda D. Hicks, James M. Battisti, Rahul Raghavan, Michael F. Minnick

Biological Sciences Faculty Publications

Coxiella burnetii, an obligate intracellular bacterial pathogen that causes Q fever, undergoes a biphasic developmental cycle that alternates between a metabolically-active large cell variant (LCV) and a dormant small cell variant (SCV). As such, the bacterium undoubtedly employs complex modes of regulating its lifecycle, metabolism and pathogenesis. Small RNAs (sRNAs) have been shown to play important regulatory roles in controlling metabolism and virulence in several pathogenic bacteria. We hypothesize that sRNAs are involved in regulating growth and development of C. burnetii and its infection of host cells. To address the hypothesis and identify potential sRNAs, we subjected total RNA …

One-On-One Delivery Of Living Well With A Disability, Tracy Boehm, Craig Ravesloot Ph.D., University Of Montana Rural Institute Rural Institute

Health and Wellness

The RTC: Rural conducted a research project on health management support for rural Americans. The approach used individually-focused programs, one of which included selected content from the Living Well with a Disability (LWD) health promotion program. The project noted that transportation and limited access to group-based programs in rural areas may act as barriers for participation in health promotion programs. Findings suggest the traditional 10- week LWD group-based program is the recommended practice, but a shorter LWD program delivered one-on-one with a consumer may be an option in rural areas.

Rural Self-Management Support, Craig Ravesloot Ph.D., Tracy Boehm, Tannis Hargrove, University Of Montana Rural Institute

Health and Wellness

The Rural Self-Management Support research project used an individually-focused health self-management support intervention to help people with disabilities locate resources for health support in rural America. This intervention led to better long term maintenance of health self-management behaviors compared to the control condition which did not include a focus on locating health resources. Future research will continue to look at how local communities impact long term health.

Uncoupling Reproduction From Metabolism Extends Chronological Lifespan In Yeast, Saisubramanian Nagarajan, Arthur L. Kruckeberg, Karen H. Schmidt, Evgueny Kroll, Morgan Hamilton, Kate Mcinnerney, Ryan Summers, Timothy Taylor, Frank Rosenzweig

Biological Sciences Faculty Publications

Studies of replicative and chronological lifespan in Saccharomyces cerevisiae have advanced understanding of longevity in all eukaryotes. Chronological lifespan in this species is defined as the agedependent viability of nondividing cells. To date this parameter has only been estimated under calorie restriction, mimicked by starvation. Because postmitotic cells in higher eukaryotes often do not starve, we developed a model yeast system to study cells as they age in the absence of calorie restriction. Yeast cells were encapsulated in a matrix consisting of calcium alginate to form ~3 mm beads that were packed into bioreactors and fed ad libitum. Under these …

Where’S The Kale? A Search For Food Security On The Northern Cheyenne Reservation, Amy R. Sisk

University of Montana Conference on Undergraduate Research (UMCUR)

Only one small grocery store serves the 5,000 people living on the Northern Cheyenne Reservation in rural southeastern Montana. Between its limited stock, fast food from a nearby convenience store and canned goods distributed to residents through the commodity program, it’s hard to come by wholesome meals. That has not stopped health-conscious people from sponsoring a host of programs to curb poor nutrition. But will their efforts go far enough to make a lasting difference across the reservation? And why is accessing quality food so difficult in this part of the state? I set out to answer these questions on …

Assessing Nutrient Limitation In Complex Forested Ecosystems : Alternatives To Large-Scale Fertilization Experiments, Benjamin W. Sullivan, Silvia Alvarez-Clare, Sarah C. Castle, Stephen Porder, Sasha C. Reed, Laura Schreeg, Cory C. Cleveland, Alan R. Townsend

Ecosystem and Conservation Sciences Faculty Publications

Quantifying nutrient limitation of primary productivity is a fundamental task of terrestrial ecosystem ecology, but in a high carbon dioxide environment it is even more critical that we understand potential nutrient constraints on plant growth. Ecologists often manipulate nutrients with fertilizer to assess nutrient limitation, yet for a variety of reasons, nutrient fertilization experiments are either impractical or incapable of resolving ecosystem responses to some global changes. The challenges of conducting large, in situ fertilization experiments are magnified in forests, especially the high-diversity forests common throughout the lowland tropics. A number of methods, including fertilization experiments, could be seen as …

Insights Into The Development And Evolution Of Exaggerated Traits Using De Novo Transcriptomes Of Two Species Of Horned Scarab Beetles, Ian A. Warren, J. Cristobal Vera, Annika Johns, Robert Zinna, James H. Marden, Douglas J. Emlen, Ian Dworkin, Laura C. Lavine

Biological Sciences Faculty Publications

Scarab beetles exhibit an astonishing variety of rigid exo-skeletal outgrowths, known as ‘‘horns’’. These traits are often sexually dimorphic and vary dramatically across species in size, shape, location, and allometry with body size. In many species, the horn exhibits disproportionate growth resulting in an exaggerated allometric relationship with body size, as compared to other traits, such as wings, that grow proportionately with body size. Depending on the species, the smallest males either do not produce a horn at all, or they produce a disproportionately small horn for their body size. While the diversity of horn shapes and their behavioural ecology …

A Conceptual Framework For Clutch-Size Evolution In Songbirds, Thomas E. Martin

Wildlife Biology Faculty Publications

Causes of evolved differences in clutch size among songbird species remain debated. I propose a new conceptual framework that integrates aspects of traditional life-history theory while including novel elements to explain evolution of clutch size among songbirds. I review evidence that selection by nest predation on length of time that offspring develop in the nest creates a gradient in offspring characteristics at nest leaving (fledging), including flight mobility, spatial dispersion, and self-feeding rate. I postulate that this gradient has consequences for offspring mortality rates and parental energy expenditure per offspring. These consequences then determine how reproductive effort is partitioned among …

Developmental Link Between Sex And Nutrition; Doublesex Regulates Sex-Specific Mandible Growth Via Juvenile Hormone Signaling In Stag Beetles, Hiroki Gotoh, Hitoshi Miyakawa, Asano Ishikawa, Yuki Ishikawa, Yasuhiro Sugime, Douglas J. Emlen, Laura C. Lavine, Toru Miura

Biological Sciences Faculty Publications

Sexual dimorphisms in trait expression are widespread among animals and are especially pronounced in ornaments and weapons of sexual selection, which can attain exaggerated sizes. Expression of exaggerated traits is usually male-specific and nutrition sensitive. Consequently, the developmental mechanisms generating sexually dimorphic growth and nutritiondependent phenotypic plasticity are each likely to regulate the expression of extreme structures. Yet we know little about how either of these mechanisms work, much less how they might interact with each other. We investigated the developmental mechanisms of sex-specific mandible growth in the stag beetle Cyclommatus metallifer, focusing on doublesex gene function and its …

Epigenetic Changes After Prenatal Environmental Tobacco Smoke Exposure And Asthma, Sonja Christensen

Graduate Student Theses, Dissertations, & Professional Papers

Allergic asthma affects over 300 million people worldwide. Multiple factors have been shown to alter an individuals' susceptibility to this allergic airway disease such as exposure to polycyclic aromatic hydrocarbons (PAHs), endotoxin, and environmental tobacco smoke (ETS). Prenatal exposure to these contaminants, especially ETS, has been shown to increase risk for an individuals’ asthma risk, however, the mechanism by which this happens is still unknown. Epigenetic alterations, particularly DNA methylation patterns, have been introduced as a proposed mechanism. The goals of this project were to use a house dust mite (HDM) murine model of asthma to determine the methylation alterations …

Cardiac Rehabilitation Enrollment Rates And Different Referral Strategies, Whitney Tameler

Graduate Student Theses, Dissertations, & Professional Papers

Cardiovascular disease is the leading cause of hospitalizations and deaths in the United States. Although cardiac rehabilitation is recognized as a standard element of continuum of cardiac care only 10-60% of eligible patients participate. Various barriers exist preventing cardiac patients to enroll in cardiac rehabilitation. These barriers are categorized into three different levels: 1) patient barriers, 2) physician barriers and 3) healthcare system barriers. Patient barriers can include lack of insurance, transportation, need to return to work, family issues and the perception cardiac rehabilitation is not needed but lack of physician referral is the leading deterrent for patients not enrolling …

Lithic Design And Technological Organization In Housepit 1 Of The S7istken Site, Middle Fraser Canyon, British Columbia, Matthew Mattes

Graduate Student Theses, Dissertations, & Professional Papers

Archaeological research of Housepit 1 at the S7istken site in the Middle Fraser region of the British Columbia Plateau has been ongoing since the summer of 2010. Housepit 1 is one of eight housepits at the site, and to date it has been excavated in near entirety. This has provided a large faunal assemblage mostly comprised of stored salmon remains, and also a lithic assemblage that has proven to be a useful measure of late prehistoric lifeways from the perspective of technological organization and lithic design strategies. Housepit 1 was occupied twice between about 350-300 B.P., which is the proto-historic …
