Potential Ecological Impact Of Diet Selectivity And Bison Herd Composition, Claudia Rosas, David Engle, James Shaw

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Behavioral segregation between the sexes of bison (Bas bison), coupled with artificially manipulated sex ratios of bison herds, might profoundly influence prairie ecosystems. Therefore, we measured carbon isotopes in hair collected from bison from the Tallgrass Prairie Preserve in northeast Oklahoma to determine if adult male, adult female, and juvenile bison segregate on the basis of botanical composition of their diet. Sex ratio of bison herds in the Great Plains and behavioral differences between sexes were used to assess potential effects of sex ratio on tallgrass prairie. Botanical composition of diet differed among the three bison groups, in …

Impact Of Reduced Lignin On Plant Fitness, Jeffrey F. Pedersen, Kenneth P. Vogel, Deanna L. Funnell

Department of Plant Pathology: Faculty Publications

Lignin content of crop plants has been reduced by traditional plant breeding, natural and induced mutations, and insertion of transgenes. The effects of these genes and associated lower lignin content have been examined in terms of agricultural fitness or with regard to economically harvestable yields of useful plant products, or, in the case of some perennial species, survivability over multiple years. In general, crop yields are depressed by significant reductions in lignin content. Other negative effects observed in plants with lowered lignin contents include lodging and reduction of long-term survival of some perennial species. However, the interactions of genes involved …

Effects Of Radiotransmitters On Fecal Glucocorticoid Metabolite Levels Of Three-Toed Box Turtles In Captivity, Chadwick D. Rittenhouse, Joshua J. Millspaugh, Brian E. Washburn, Michael W. Hubbard

United States Department of Agriculture Wildlife Services: Staff Publications

The increased use of radio-telemetry for studying movement, resource selection, and population demographics in reptiles necessitates closer examination of the assumption that radiotransmitter attachment does not bias study results. We determined the effects of radiotransmitter attachment on fecal glucocorticoid metabolite levels of wild three-toed box turtles (Terrapene carolina triunguis) in captivity. During May 2002 we captured 11 adult three-toed box turtles in central Missouri. We housed turtles in individual pens in a semi-natural outdoor setting. We radio-tagged 6 turtles, and the remaining 5 turtles served as controls. We captured and handled all turtles similarly during treatments. We collected …

Influence Of The Number Of Repellent-Treated And Untreated Food Or Water Containers On Intake By The European Starling, Arla G. Hile, Michael G. Tordoff

United States Department of Agriculture Wildlife Services: Staff Publications

The availability of multiple sources of food and drink has a profound influence on choice behavior in rodents. It is not known how other taxa might respond to the same kind of variation in availability. We tested European starlings (Sturnus vulgaris) with various combinations of unadulterated and repellent-treated (0.025% citronellyl acetate) resources. In Experiment 1, birds drank more plain than repellent-treated water than when given (a) 2 bottles of plain water and 2 of repellent-water, or (b) 3 bottles of plain water and 1 of repellent-water. However, they drank more repellent than water when given 3 bottles of repellent-water and …

Stochastic Dietary Restriction Using A Markov-Chain Feeding Protocol Elicits Complex, Life History Response In Medflies, James R. Carey, Pablo Liedo, Hans-Georg Müller, Jane-Ling Wang, Ying Zhang, Lawrence G. Harshman

Lawrence G. Harshman Publications

Lifespan in individually housed medflies (virgins of both sexes) and daily reproduction for females were studied following one of 12 dietary restriction (DR) treatments in which the availability of high-quality food (yeast–sugar mixture) for each fly was based on a Markov chain feeding scheme – a stochastic dietary regime which specifies that the future dietary state depends only on the present dietary state and not on the path by which the present state was achieved. The stochastic treatments consisted of a combination of one of four values of a ‘discovery’ parameter and one of three values of a ‘persistence’ parameter. …

Department of Plant Pathology: Faculty Publications

The impact of filamentous fungi on human welfare has never been greater. Fungi are acknowledged as the most economically devastating plant pathogens (1) and are attaining increasing notoriety for their ability to cause life-threatening infections in humans (57, 71), and fungal products sustain a billion dollar manufacturing industry (70). The tools available to study filamentous fungi are more sophisticated than ever and include the complete annotated genome sequences of multiple filamentous fungi (12), resources being made available through various functional genomics projects, and advanced bioimaging methods, including high-resolution live-cell imaging (20, 32) and electron tomography (19, 50). The increasing impact …

Tritrophic Interaction Of Parasitoid Lysiphlebus Testaceipes (Hymenoptera: Aphidiidae), Greenbug, Schizaphis Graminum (Homoptera: Aphididae), And Greenbug-Resistant Sorghum Hybrids, Mahmut Dogramaci, Z. B. Mayo, Robert J. Wright, John C. Reese

Department of Entomology: Faculty Publications

Interactions of the parasitoid Lysiphlebus testaceipes (Cresson) and the greenbug, Schizaphis graminum (Rondani), on greenbug-resistant ‘Cargill 607E’ (antibiosis), ‘Cargill 797’ (primarily tolerance), and -susceptible ‘Golden Harvest 510B’ sorghum, Sorghum bicolor (L.) Moench, were tested using three levels of biotype I greenbug infestation. The parasitoid infestation rate was 0.5 female and 1.0 male L. testaceipes per plant. For all three greenbug infestation levels, the parasitoid brought the greenbug under control (i.e., prevented the greenbugs from killing the plants) on both resistant hybrids, but it did not prevent heavy leaf damage at the higher greenbug infestation rates. At the low greenbug infestation …

Effect Of Bio-Optical Parameter Variability On The Remote Estimation Of Chlorophyll-A Concentration In Turbid Productive Waters: Experimental Results, Giorgio Dall'olmo, Anatoly A. Gitelson

School of Natural Resources: Faculty Publications

The analytical development and underlying hypothesis of a three-band algorithm for estimating chlorophyll-a concentration ([Chla]) in turbid productive waters are presented. The sensitivity of the algorithm to the spectral location of the bands used is analyzed. A large set of experimental observations ([Chla] varied between 4 and 217 mg m^-3 and turbidity between 2 and 78 nephelometric turbidity units) was used to calibrate and validate the algorithm. It was found that the variability of the chlorophyll-a fluorescence quantum yield and of the chlorophyll-a specific absorption coefficient can reduce considerably the accuracy of remote predictions of [Chla]. Instead of parameterizing …

Using Ems’S To Improve Compliance On Livestock And Poultry Operations, L. Mark Risse, Richard K. Koelsch, W. L. Bland, Elizabeth A. Bird, Thomas M. Bass

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

Across the United States and abroad, innovative producers, processors, trade organizations and others in the agricultural sector are exploring the promise of Environmental Management Systems (EMS) to improve their environmental and business performance. An Environmental Management System or EMS helps farmers develop their own, personal strategies for reducing environmental risk on their operations by integrating environmental management considerations into production management decisions. It is a voluntary, flexible approach and is based on a producer's own sense of how best to manage an operation.

Partnerships for Livestock Environmental Management Systems is a 4-year project to explore the potential of livestock Environmental …

Secretion Of Recombinant Human Fibrinogen By The Murine Mammary Gland, William H. Velander

Papers in Biotechnology

Transgenic animals secreting individual chains and assembled fibrinogen were produced to evaluate the capacity of the mammary gland for maximizing assembly, glycosylation and secretion of recombinant human fibrinogen (rhfib). Transgenes were constructed from the 4.1 kbp murine Whey Acidic Protein promoter (mWAP) and the three cDNAs coding for the Aα,Bβ and γ fibrinogen chains. Transgenic mice secreted fully assembled fibrinogen into milk at concentrations between 10 and 200 μg/ml, with total secretion of subunits approaching 700 μ g/ml in milk. Partially purified fibrinogen was shown to form a visible and stable clot after treatment with human thrombin and factor XIII. …

Effects Of Spring Supplementary Feeding On Population Density And Breeding Success Of Released Pheasants Phasianus Colchicus In Britain, Roger A. H. Draycott, Maureen I. A. Woodburn, John P. Carroll, Rufus B. Sage

School of Natural Resources: Faculty Publications

The release of hand-reared ring-necked pheasants Phasianus colchicus in summer is a common practice in Britain to increase the number of birds available to hunters in winter. The breeding success of the birds which survive the shooting season is poor. Traditionally, birds are provided with supplementary wheat grain from release until the end of the shooting season (1 February) to maintain body condition and to help hold birds in areas for hunting. During 1997- 2000 we assessed the effect of continuing supplementary feeding into spring on pheasant density and breeding success on seven private shooting estates. On each estate we …

Effects Of Supplementation Of Whole Corn Germ On Reproductive Performance, Calf Performance, And Leptin Concentration In Primiparous And Mature Beef Cows, J. L. Martin, Richard J. Rasby, Dennis R. Brink, R. U. Lindquist, D. H. Keisler, Stephen D. Kachman

Department of Statistics: Faculty Publications

A 2-yr study using primiparous and multiparous, spring-calving, crossbred beef cows was conducted to evaluate the effects of supplemental whole corn germ on reproductive performance, calf performance, and serum leptin concentrations. Each year, cows were blocked by age and BCS and assigned randomly to one of three treatments: PRE (n = 115) cows received 1.14 kg/d (DM basis) of whole corn germ for approximately 45 d before calving; POST (n = 109) cows were fed 1.14 kg/d of whole corn germ for approximately 45 d after calving; and control cows (n = 118) were fed similar energy and protein from …
