Multiple-Scale Roost Habitat Comparisons Of Female Merriam's Wild Turkeys In The Southern Black Hills, South Dakota, Daniel J. Thompson, Mark A. Rumble, Lester D. Flake, Chad P. Lehman

Western North American Naturalist

Because quantity and quality of roosting habitat can affect Merriam's Wild Turkey (Meleagris gallopavo merriami) distribution, we described habitat characteristics of Merriam's turkey roost sites in the southern Black Hills of South Dakota. Varying proportions of Merriam's turkeys in the southern Black Hills depended on supplemental feed from livestock operations during the 2 winters of our study, whereas the remainder wintered in forested habitat away from supplemental feed. We compared characteristics of roost habitat occupied by female turkeys from both groups. We located turkeys with radio-transmitters in the early morning and late evening to find roost sites. Female …

Sperm Viability In The Reproductive Tract Of Females In A Population Of Sceloporus Mucronatus Exhibiting Asynchronous Reproduction, Angela M. Ortega-León, Maricela Villagrán–Santa Cruz, J. Jamie Zúñiga-Vega, Raúl Cueva–Del Castillo, Fausto R. Méndez–De La Cruz

Western North American Naturalist

Asynchronous reproduction is a common phenomenon in high-elevation populations of lizards from Central México. Sperm storage in the reproductive tract of females is the mechanism for making oocyte fertilization possible. Our study addresses questions related to functional oviductal sperm storage of females mating on different dates throughout the reproductive season. A population of Sceloporus mucronatus with copulation in the summer and ovulation in the fall was chosen for this experiment. Eleven females that copulated in the field during June and 13 females that copulated in captivity during August were maintained in the laboratory until parturition. The number of pregnant females …

Bats Associated With Inactive Mines In The Western Great Basin, Michael L. Morrison, Sue Fox

Western North American Naturalist

We surveyed bats using echolocation calls near inactive mines in the western Great Basin from 2003 to 2007. We identified 14 species of bats during our surveys, with Myotis lucifugus and Lasionycteris noctivagans found at 9 sites and Myotis evotis and Tadarida brasiliensis at 7 sites; all other species were found at less than one-half of the sites. Euderma maculatum, a state-protected species in Nevada, was recorded at 2 sites. Our work provides information that will be useful in managing bat habitat, especially with regard to mining activities.

A Comparison Of The Discriminative Stimulus Properties Of The Atypical Antipsychotic Clozapine And The Glutamate Agonist N-Methyl D-Aspartate In C57bl/6 Mice., Sarah A. Vunck

Theses and Dissertations

The glutamate system dysfunctions present in schizophrenia raise new questions about possible glutamatergic actions of the atypical antipsychotic clozapine. While clozapine has been shown to partially substitute for the discriminative stimulus of the glutamate agonist N-methyl D-aspartate (NMDA) in rats, NMDA discrimination has not previously been established in mice. The present study was designed to explore the possible role of NMDA activity in clozapine’s discriminative stimulus. Two groups of C57BL/6 mice were trained to discriminate either 2.5 mg/kg CLZ from vehicle or 30 mg/kg NMDA from vehicle in a standard two-lever drug discrimination task. NMDA drug discrimination was successfully established …

Examination Of The Discriminative Stimulus And Cross-Tolerance Inducing Properties Of N-Desmethylclozapine In C57bl/6 Mice., Jason Wiebelhaus

Theses and Dissertations

Due to its unique receptor binding profile and its relationship to clozapine, N-desmethylclozapine (NDMC) has been examined as a possible antipsychotic drug (APD). Clozapine has been trained as discriminative stimulus in our lab, but NDMC has not yet been established as a discriminative stimulus. In experiment 1, 12 C57BL/6 mice were trained to discriminate 10.0 mg/kg NDMC from VEH using a standard-two lever operant procedure to assess antipsychotic substitution. The typical APD clozapine fully substituted for NDMC at 2 doses tested (2.5 and 5.0 mg/kg), while typical APD haloperidol failed to substitute for NDMC. In Experiment 2, 11 mice were …

Obesity, Adiposity, And Satiety In Mouse Models Of Smith-Magenis Syndrome And Dup(17)(P11.2) Syndrome, Brooke Burns

Theses and Dissertations

Smith-Magenis syndrome (SMS) is a complex disorder caused by haploinsufficiency of RAI1 and characterized by sleep disturbances, behavioral abnormalities, mental retardation, and obesity in teens and adults. Rai1+/- mice are obese after 20 weeks. Dup(17)(p11.2) syndrome is a complex disorder associated with overexpression of RAI1. A transgenic mouse model of dup(17)(p11.2) syndrome overexpresses Rai1 and results in a mouse that is growth delayed. In order to characterize the obese phenotypes of mouse models of SMS and the role of RAI1 in obesity, daily food intake and serum levels of insulin, glucose, PPY, and leptin were measured; adiposity was studied by …

Regional And Seasonal Diet Of The Western Burrowing Owl In South Central Nevada, Derek B. Hall, Paul D. Greger, Jeffrey R. Rosier

Western North American Naturalist

We examined diets of Western Burrowing Owls (Athene cunicularia hypugaea) based on contents of pellets and large prey remains collected year-round at burrows in each of the 3 regions in south central Nevada (Mojave Desert, Great Basin Desert, and Transition region). The most common prey items, based on percent frequency of occurrence, were crickets and grasshoppers, beetles, rodents, sun spiders, and scorpions. The most common vertebrate prey was kangaroo rats (Dipodomys spp.). True bugs (Hemiptera), scorpions, and western harvest mice (Reithrodontomys megalotis) occurred most frequently in pellets from the Great Basin Desert region. Kangaroo rats …

Dynamic Responses Of A British Columbian Forest-Grassland Interface To Prescribed Burning, Kim Ducherer, Yuguang Bai, Don Thompson, Klaas Broersma

Western North American Naturalist

Ponderosa pine Pinus ponderosa and Douglas-fir Pseudotsuga menziesii forests in the Interior of British Columbia, Canada, are adjacent to grasslands. Forest ingrowth and tree encroachment, mainly due to fire suppression, represent threats to both forest and ranching industries in the region. The use of prescribed burning for ecological restoration is being practiced, but the associated ecosystem effects of restoration treatments have been little studied in the region. We used a randomized complete block design in a prescribed burning experiment. Tree survival and the responses of understory vegetation to burning were monitored for 3 years. The transect method along with crown …

Relationship Between Cheatgrass Coverage And The Relative Abundance Of Snakes On Antelope Island, Utah, Lucas K. Hall, John F. Mull, John F. Cavitt

Western North American Naturalist

Cheatgrass (Bromus tectorum) is an invasive annual known to negatively impact many shrub-dependent organisms; however, relatively little research has examined how it affects snake communities. Bromus tectorum is abundant at Antelope Island State Park, Davis County, Utah, and could be a possible threat to snake populations. Study sites representing different B. tectorum coverage percentages were established to measure relative abundance of snakes. Snakes were captured from June to September 2005 primarily by using funnel traps attached to drift-fence arrays. Linear regression revealed a negative relationship between B. tectorum coverage (%) and the relative abundance of the Great Basin …

Grass Rhizosheaths: Associated Bacterial Communities And Potential For Nitrogen Fixation, David Bergmann, Mike Zehfus, Linda Zierer, Brian Smith, Mark Gable

Western North American Naturalist

Rhizosheaths are structures composed of mucilage secreted from plants and adherent soil particles that form a cylinder around the root. Using scanning electron microscopy (SEM), we observed bacteria associated with rhizosheaths of the grasses Achnatherum hymenoides, Calamovilfa longifolia, Hesperostipa comata, and Pascopyrum smithii from a sand dune area in Harding County in northwestern South Dakota. The greatest numbers of bacteria, observed with SEM (529 mm⁻²), and the greatest number of culturable bacteria (9.9 × 10⁷ CFU · g⁻¹ or 5178 CFU · mm⁻²) were on rhizosheaths of C. longifolia. Rhizosheaths of all the grasses …

Maternal Defensive Behavior Of Mountain Goats Against Predation By Golden Eagles, Sandra Hamel, Steeve D. Côté

Western North American Naturalist

Maternal defensive behavior against predators may appear risky but is common in many species. Herein we describe maternal defensive behavior of mountain goats (Oreamnos americanus) against Golden Eagle (Aquila chrysaetos) predatory attempts. We found that Golden Eagles attacked goats in 1.9% of sightings (n = 311 sightings of active Golden Eagles over 12 years) but were never successful. Mothers always defended their young against Golden Eagle attacks. Predation by Golden Eagles on young-of-the-year appears low for most ungulate species, including mountain goats. The benefits of defending offspring against eagles are likely high in ungulates, and …

Home-Range Size And Overlap Of Sympatric Male Mule And White-Tailed Deer In Texas, Kristina J. Brunjes, Warren B. Ballard, Mary H. Humphrey, Fielding Harwell, Nancy E. Mcintyre, Paul R. Krausman, Mark C. Wallace

Western North American Naturalist

Information about the ecology of sympatric male deer is limited, which may influence management strategies for these species. We estimated home-range and core-area sizes and overlap, and survival of sympatric male desert mule deer (Odocoileus hemionus eremicus) and white-tailed deer (Odocoileus virginianus) in west central Texas. We captured 18 males of each species, fitted them with radio-collars, and monitored them for mortality from 2000 through 2003. We calculated home ranges for 7 males of each species in 2001 and 2002. Home-range sizes of mule deer (8.8 km²) and white-tailed deer (7.4 km²) …

Benthic Macroinvertebrate Diversity In A Shallow Estuary: Controls On Nutrient And Algal Dynamics, Natalie Ann Mclenaghan

Theses

Nutrient loading has produced radical shifts in the structure and function of shallow estuaries, with substantial impacts upon the community composition of invertebrates and autotrophs. The progression of eutrophication is regulated by both bottom-up and top-down factors, which may be mediated by fauna via trophic interactions and nutrient release. We conducted field surveys of benthic invertebrates in West Falmouth Harbor (WFH), MA, an estuary subject to localized wastewater enrichment, across a 1 km gradient of suspected degradation. Dominant taxa included gammarid amphipods and nereidid, orbiniid, and capitellid polychaetes, with lower diversity and opportunistic species characterizing the inner basin nearest the …

Upregulation Of Pip3-Dependent Rac Exchanger 1 (P-Rex1) Promotes Prostate Cancer Metastasis., Jianbing Qin, Yan Xie, Bo Wang, Mikio Hoshino, Dennis W. Wolff, Jing Zhao, Margaret A. Scofield, Frank J. Dowd, Ming-Fong Lin, Yaping Tu

Journal Articles: Biochemistry & Molecular Biology

Excessive activation of G-protein-coupled receptor (GPCR) and receptor tyrosine kinase (RTK) pathways has been linked to prostate cancer metastasis. Rac activation by guanine nucleotide exchange factors (GEFs) plays an important role in directional cell migration, a critical step of tumor metastasis cascades. We found that the upregulation of P-Rex1, a Rac-selective GEF synergistically activated by Gbetagamma freed during GPCR signaling, and PIP3, generated during either RTK or GPCR signaling, strongly correlates with metastatic phenotypes in both prostate cancer cell lines and human prostate cancer specimens. Silencing endogenous P-Rex1 in metastatic prostate cancer PC-3 cells selectively inhibited Rac activity and reduced …

A Bioeconomic Approach To Marriage And The Sexual Division Of Labor, Michael Gurven, Jeffrey Winking, Hillard Kaplan, Christopher Von Rueden, Lisa Mcallister

ESI Publications

Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other.We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, …
