Bats Of Barbuda, Northern Lesser Antilles, Scott C. Pedersen, Peter A. Larsen, Hugh H. Genoways, Matthew Morton, Kevel C. Lindsay, Jerry Cindric Oct 2007

Bats Of Barbuda, Northern Lesser Antilles, Scott C. Pedersen, Peter A. Larsen, Hugh H. Genoways, Matthew Morton, Kevel C. Lindsay, Jerry Cindric

University of Nebraska State Museum: Mammalogy Papers

Five species of bats are known to occur on the Lesser Antillean island of Barbuda—Noctilio leporinus, Monophyllus plethodon, Brachyphylla cavernarum, Tadarida brasiliensis, and Molossus molossus. During the present study, two additional species of bats—Artibeus jamaicensis and Natalus stramineus—were added to the chiropteran fauna of the island. Although the ecological diversity of Barbuda is limited, this bat fauna matches those of islands in the region such as Antigua, Nevis, and St. Kitts. It is proposed that this biodiversity of bats is maintained because of the geology of Barbuda provides ample roosting sites and access to freshwater …


Does Interference Competition With Wolves Limit The Distribution And Abundance Of Coyotes?, Kim Murray Berger, Eric M. Gese Oct 2007

Does Interference Competition With Wolves Limit The Distribution And Abundance Of Coyotes?, Kim Murray Berger, Eric M. Gese

United States Department of Agriculture Wildlife Services: Staff Publications

1. Interference competition with wolves Canis lupus is hypothesized to limit the distribution and abundance of coyotes Canis latrans, and the extirpation of wolves is often invoked to explain the expansion in coyote range throughout much of North America.

2. We used spatial, seasonal and temporal heterogeneity in wolf distribution and abundance to test the hypothesis that interference competition with wolves limits the distribution and abundance of coyotes. From August 2001 to August 2004, we gathered data on cause-specific mortality and survival rates of coyotes captured at wolf-free and wolf-abundant sites in Grand Teton National Park (GTNP), Wyoming, USA, …


Effect Of Climatic Warming On The Pacific Walrus, And Potential Modification Of Its Helminth Fauna [Critical Comment], Robert L. Rausch, John C, George, Harry K. Brower Oct 2007

Effect Of Climatic Warming On The Pacific Walrus, And Potential Modification Of Its Helminth Fauna [Critical Comment], Robert L. Rausch, John C, George, Harry K. Brower

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The decreasing extent of sea-ice in the arctic basin as a consequence of climatic warming is modifying the behavior and diets of pagophilic pinnipeds, including the Pacific walrus, Odobenus rosmarus divergens Illiger, the species emphasized here. Mammals such as the walrus and bearded seal, Erignathus barbatus (Erxleben), cannot remain associated with the sea-ice, and continue to feed on their usual diet of benthic invertebrates inhabiting coastal waters to a depth of approximately 100 m, when the northwestward retreating ice reaches deep waters beyond the margins of the continental shelf. With reduction of their customary substrate (ice), the walrus has become …

Software Tool For Integrating Feed Management Into Nutrient Planning, Richard K. Koelsch, Ray Massey, Galen E. Erickson, Virgil R. Bremer Sep 2007

Software Tool For Integrating Feed Management Into Nutrient Planning, Richard K. Koelsch, Ray Massey, Galen E. Erickson, Virgil R. Bremer

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

The introduction of ASABE Standard D384.2, Manure Production and Characteristics, has created the opportunity to integrate feed management decisions and animal performance measures into nutrient planning processes. This paper introduces a software tool that integrates estimates of nutrient excretion based on the new standard with estimates of land need, labor and equipment time allocation, and economic cost and benefit for manure application. This tool will be used to evaluate the economic implications for two scenarios using beef cattle examples as a means of illustrating tool application. The first scenario will look at the impact of feeding ethanol co-products on the …


Distinct Mechanisms For Ctr1-Mediated Copper And Cisplatin Transport, Devis Sinani, David J. Adle, Heejeong Kim, Jaekwon Lee Sep 2007

Distinct Mechanisms For Ctr1-Mediated Copper And Cisplatin Transport, Devis Sinani, David J. Adle, Heejeong Kim, Jaekwon Lee

Department of Biochemistry: Faculty Publications

The Ctr1 family of integral membrane proteins is necessary for high affinity copper uptake in eukaryotes. Ctr1 is also involved in cellular accumulation of cisplatin, a platinum-based anticancer drug. Although the physiological role of Ctr1 has been revealed, the mechanism of action of Ctr1 remains to be elucidated. To gain a better understanding of Ctr1-mediated copper and cisplatin transport, we have monitored molecular dynamics and transport activities of yeast Saccharomyces cerevisiae Ctr1 and its mutant alleles. Co-expression of functional Ctr1 monomers fused with either cyan or yellow fluorescent protein resulted in fluorescence resonance energy transfer (FRET), which is consistent with …

Vadim Gladyshev Publications

Novel mouse models were developed in which the hepatic selenoprotein population was targeted for removal by disrupting the selenocysteine (Sec) tRNA [Ser]Sec gene (trsp) and then selenoprotein expression was restored by introducing wild type or mutant trsp transgenes. The selenoprotein population was partially replaced in liver with mutant transgenes encoding mutations at either position 34 (T34->A34) or 37 (A37->G37) in tRNA [Ser]Sec. The A34 transgene product lacked the highly modified 5-methoxycarbonylmethyl-2’ O-methyluridine and its mutant base A was converted to I34. The G37 transgene product lacked the highly modified N6-isopentenyladenosine. Both mutant tRNAs …

Birds, George M. Linz, Jim Hanzel Sep 2007

Birds, George M. Linz, Jim Hanzel

United States Department of Agriculture Wildlife Services: Staff Publications

Sunflower, due to the easy accessibility and high nutritional value of its seed, is particularly vulnerable to damage by birds (Figure 101). Seeds are exposed and the large head serves as a perch during feeding. Sunflower seed is a preferred bird food because the seed contains many proteins and fats essential to their growth, molt, fat storage and weight maintenance processes. Although many species of birds feed in maturing sunflower fields, the greatest losses are caused by migrating flocks of red-winged blackbirds, yellow- headed blackbirds and common grackles (Figure 102). Significant losses can occur in fields near cattail marshes.


Foraging Preferences Of Captive Canada Geese Related To Turfgrass Mixtures, Brian E. Washburn, Scott C. Barras, Thomas W. Seamans Sep 2007

Foraging Preferences Of Captive Canada Geese Related To Turfgrass Mixtures, Brian E. Washburn, Scott C. Barras, Thomas W. Seamans

United States Department of Agriculture Wildlife Services: Staff Publications

Overabundant populations of Canada geese (Branta canadensis) cause economic and safety concerns associated with collisions with civil and military aircraft. Habitat management techniques that reduce the use of airfield habitats by geese might reduce these concerns. The objective of this study was to determine if captive Canada geese exhibited a foraging preference between a vegetation mixture consisting mostly of perennial ryegrass (Lolium perenne) and white clover (Trifolium repens) versus an endophyte-infected tall fescue- (Festuca arundinacea) based vegetation mixture. We established 6 paired plots of perennial ryegrass-dominated and tall fescue-dominated mixtures at NASA …

Internode Structure And Cell Wall Composition In Maturing Tillers Of Switchgrass (Panicum Virgatum. L), Gautam Sarath, Lisa M. Baird, Kenneth P. Vogel, Robert B. Mitchell Aug 2007

Internode Structure And Cell Wall Composition In Maturing Tillers Of Switchgrass (Panicum Virgatum. L), Gautam Sarath, Lisa M. Baird, Kenneth P. Vogel, Robert B. Mitchell

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

This work examined cell composition gradients in maturing tillers of switchgrass (Panicum virgatuln L. ) with the aim of developing baseline information on this important forage and biomass crop. Flowering tillers were collected from plants raised from seeds in a greenhouse and field, harvested at soil level and separated into internodes beginning with the node subtending the peduncle. Internodes were analyzed using microscopy, by fiber digestion, high-performance liquid chromatography and by gas chromatography-mass spectrometry to obtain anatomical and compositional data. Microscopy demonstrated the development and maturation of cortical fibers which eventually became confluent with the fiber sheath surrounding vascular …

Shifting From A Price Safety Net To A Revenue Safety Net, Bradley Lubben, Troy J. Dumler, G. Art Barnaby

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

In late July, the U.S. House of Representatives passed the Farm, Nutrition, and Bioenergy Act of 2007, or the “2007 Farm Bill,” to reauthorize farm, food, and other agricultural programs for 2008 through 2012. This culminated more than two months of discussion in the House Agriculture Committee and subcommittees and reflected much of the policy direction championed by committee chair Collin Peterson of Minnesota.

In the Senate, the agricultural committee under Chairman Tom Harkin of Iowa has yet to begin formal consideration of the 2007 Farm Bill. However, given some comments from Senator Harkin, there are some elements of …


The Ecology Of Vertebrate Pests And Integrated Pest Management (Ipm), Gary W. Witmer Aug 2007

The Ecology Of Vertebrate Pests And Integrated Pest Management (Ipm), Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Across the world, vertebrates cause considerable annual damage to agriculture, property, human health and safety, and natural resources. Although some species of all vertebrate groups have been implicated in damage, the species most often involved in serious amounts of damage are birds and mammals. Agroecosystems have provided many new opportunities for vertebrates to exploit, resulting in their becoming serious "pests" with humans taking various steps to protect their agricultural resources. This conflict has intensified as the human population has increased, efforts to get more production out of traditional croplands have intensified, and marginal lands have been placed into crop production. …


Isotype-Specific Antibody Responses Against Escherichia Coli O157:H7 Locus Of Enterocyte Effacement Proteins In Adult Beef Cattle Following Experimental Infection, G. Bretschneider, E. M. Berberov, Rodney A. Moxley Aug 2007

Isotype-Specific Antibody Responses Against Escherichia Coli O157:H7 Locus Of Enterocyte Effacement Proteins In Adult Beef Cattle Following Experimental Infection, G. Bretschneider, E. M. Berberov, Rodney A. Moxley

School of Veterinary and Biomedical Sciences: Faculty Publications

Escherichia coli O157:H7 is an important food-borne pathogen and cause of hemorrhagic colitis and hemolytic uremic syndrome in humans. Cattle are an important reservoir of E. coli O157:H7, in which the organism colonizes the intestinal tract and is shed in the feces. Vaccination of cattle has significant potential as a pre-harvest intervention strategy for E. coli O157:H7; however, basic information about the bovine immune responses to important bacterial colonization factors resulting from infection has not been reported. The serum and fecal IgG and IgA antibody responses of adult cattle to E. coli O157:H7 intimin, translocated intimin receptor (Tir), E. coli …

Chinese Family Strengths And Resiliency, Anqi Xu, Xiaolin Xie, Wenli Liu, Yan Ruth Xia, Dalin Liu

Department of Child, Youth, and Family Studies: Faculty Publications

Chinese family and marriage strengths and challenges are delineated in this article, including equity in marriage, affection, the ability to adapt to changes, mutual trust, compatibility, harmony, and family support. Despite the fact that Chinese households are getting smaller as a result of governmental policy and the broadening of housing markets, families remain crucial support networks, especially in the areas of socialization and intergenerational relationships. Current research on Chinese marriages and families is cited, outlining attitudinal changes regarding mate selection, divorce, and childbirth between genders, between older and younger generations, and between urban and rural residents.


Probabilistic Bioenergetic/Toxicity Modeling Approach For Estimating Toxicant Induced Mortality To Target Invasive Species And Non-Target Wildlife, John Johnston, Randal S. Stahl, H. Jeffrey Homan, George M. Linz, Will C. Pitt Aug 2007

Probabilistic Bioenergetic/Toxicity Modeling Approach For Estimating Toxicant Induced Mortality To Target Invasive Species And Non-Target Wildlife, John Johnston, Randal S. Stahl, H. Jeffrey Homan, George M. Linz, Will C. Pitt

Managing Vertebrate Invasive Species

Non-target species may be exposed to rodenticides via feeding on rodenticide baits or the carcasses of poisoned target species. As invasive species frequently negatively impact threatened or endangered (T and E) species, there is frequently spatial and temporal overlap of invasive species and T and E species. Risk assessments provide a means to estimate the probability of rodenticide associated adverse effects to non-target species (including T and E species). Quantification of risk provides critical information for decision-makers to weigh the benefits and risks of proposed rodenticide uses and to compare the risks of management with risks associated with no management …


Research And Development Of A New Rodenticide For Nutria, Jeff J. Mach, Richard M. Poche Aug 2007

Research And Development Of A New Rodenticide For Nutria, Jeff J. Mach, Richard M. Poche

Managing Vertebrate Invasive Species

The nutria (Myocastor coypus) is a large semi-aquatic rodent, declared as one of the 100 worst invasive species in the world by the IUCN Invasive Species Specialist Group in 2000. Through USDA Small Business Innovative Research Phase I (Mach 2004) and Phase II (Mach 2006) funding, Genesis is developing a new nutria rodenticide as an alternative to the currently-registered zinc phosphide bait. Our course of research and development is described herein: live-trapping, laboratory non-toxic choice studies, laboratory toxicity bioassays, and field toxicity studies. Two active ingredients and two bait types proved to be successful, however, only cholecalciferol in …


Genetic Options For The Control Of Invasive Vertebrate Pests: Prospects And Constraints, Ronald E. Thresher Aug 2007

Genetic Options For The Control Of Invasive Vertebrate Pests: Prospects And Constraints, Ronald E. Thresher

Managing Vertebrate Invasive Species

Conventional methods for the control of invasive pests are generally effective only on small-space scales or short-time frames. For most well established pest populations, longer-term efforts to manage the problem have been largely abandoned. I examine the potential of using “autocidal” genetic techniques to control terrestrial vertebrate pests, based on the inheritance through males of transgenes that either sterilize females or convert them into functional males (“daughterless”). Simulation analysis of two high profile pest species, the cane toad (Bufo marinus) in Australia and brown rats (Rattus norvegicus) in an urban environment, using realistic parameters, suggests that …

Tillage And Rotation Effect On Corn–Soybean Energy Balances In Eastern Nebraska, G.-W. Rathke, Brian Wienhold, Wallace Wilhelm, W. Diepenbrock Aug 2007

Tillage And Rotation Effect On Corn–Soybean Energy Balances In Eastern Nebraska, G.-W. Rathke, Brian Wienhold, Wallace Wilhelm, W. Diepenbrock

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Data from a field experiment conducted in eastern Nebraska over 16 years (1986–2001) were used to determine the energy balance of corn (Zea mays L.) and soybean (Glycine max L.) as affected by tillage treatments and rotation. Tillage treatments included chisel plow, tandem disk, moldboard plow, ridge-tillage, no-till and subsoil tillage. Crop sequences were continuous corn, continuous soybean, corn in a corn–soybean rotation and soybean in a soybean–corn rotation. The energy balance was assessed by comparing the parameters: energy gain (net energy output), energy intensity (energy input per unit grain equivalent, GE) and output/input ratio. Changes in plant …
