Survey Of Whole Air Data From The Second Airborne Biomass Burning And Lightning Experiment Using Principal Component Analysis, Felisa A. Smith, Yunsoo Choi, Scott Elliott, Isobel J. Simpson, Donald R. Blake, Jonah J. Colman, Manvendra K. Dubey, Simone Meinardi, F. Sherwood Rowland, Tomoko Shirai

Biology Faculty & Staff Publications

Hydrocarbon and halocarbon measurements collected during the second airborne Biomass Burning and Lightning Experiment (BIBLE-B) were subjected to a principal component analysis (PCA), to test the capability for identifying intercorrelated compounds within a large whole air data set. The BIBLE expeditions have sought to quantify and understand the products of burning, electrical discharge, and general atmospheric chemical processes during flights arrayed along the western edge of the Pacific. Principal component analysis was found to offer a compact method for identifying the major modes of composition encountered in the regional whole air data set. Transecting the continental monsoon, urban and industrial …

Enrichment Of A Single Clone From A High Diversity Library Of Phage-Displayed Antibodies By Panning With Anopheles Gambiae (Diptera: Culicidae) Midgut Homogenate, G. F. Killeen, B. D. Foy, R. H. Frohn, D. Impoinvil, A. Williams, J. C. Beier

All Peer-Reviewed Publications

A high diversity library of recombinant human antibodies was selected on complex antigen mixtures from midguts of female Anopheles gambiae Giles. The library of phage-displayed single chain variable region fragment constructs, derived from β-lymphocyte mRNA of naïve human donors, was repeatedly selected and reamplified on the insoluble fraction of midgut homogenates. Five rounds of panning yielded only one midgut-specific clone, which predominated the resulting antibody panel. In A. gambiae, the epitope was found throughout the tissues of females but was absent from the midgut of males. The cognate antigen proved to be detergent soluble but very sensitive to denaturation and …

Bible A Whole-Air Sampling As A Window On Asian Biogeochemistry, Felisa A. Smith, Scott Elliott, Donald R. Blake, Nikola J. Blake, Manvendra D. Dubey, F. Sherwood Rowland, Barkley C. Sive

Biology Faculty & Staff Publications

Asian trace gas and aerosol emissions into carbon, nitrogen, and other elemental cycles will figure prominently in near term Earth system evolution. Atmospheric hydrocarbon measurements resolve numerous chemical species and can be used to investigate sourcing for key geocarriers. A recent aircraft study of biomass burning and lightning (BIBLE A) explored the East Asian atmosphere and was unique in centering on the Indonesian archipelago. Samples of volatile organics taken over/between the islands of Japan, Saipan, Java, and Borneo are here examined as a guide to whole-air-based studies of future Asian biogeochemistry. The midlatitude onshore/offshore pulse and tropical convection strongly influence …

Comparative Analysis Of Microsatellite Loci In Four Fruit Fly Species Of The Genus Ceratitis (Diptera: Tephritidae), F. N. Baliraine, M. Bonizzoni, E. O. Osir, S. A. Lux, F. J. Mulaa, L. Zheng, L. M. Gomulski, G. Gasperi, A. R. Malacrida

All Peer-Reviewed Publications

The possibility to cross-species amplify microsatellites in fruit flies of the genus Ceratitis was tested with the polymerase chain reaction (PCR) by analysing 23 Ceratitis capitata (Wiedemann) microsatellite markers on the genomic DNA of three other economically important, congeneric species: C. rosa (Karsch), C. fasciventris (Bezzi) and C. cosyra (Walker). Twenty-two primer pairs produced amplification products in at least one of the three species tested. The majority of the products were similar, if not identical in size to those expected in C. capitata. The structures of the repeat motifs and their flanking sequences were examined for a total of 79 …

Dangerous Animals In Captivity: Ex Situ Tiger Conflict And Implication For Private Ownership Of Exotic Animals, Philip J. Nyhus, Ronald L. Tilson, J L. Tomlinson

Faculty Scholarship

The risks associated with tiger attacks on people in the wild are well documented. There may currently be more tigers in captivity than in the wild, but relatively little is known about the risks of injury or death associated with owning and managing captive tigers and other large carnivores. The purpose of this study was to conduct a global assessment of attacks by captive tigers on people, with particular emphasis on cases in the United States. Our analysis of 30 international media sources and additional documents uncovered 59 unique incidents in 1998-2001 in which people were reportedly injured or killed …

An Ecosystem-Based Approach To Management: Using Individual Behaviour To Predict The Indirect Effects Of Antarctic Krill Fisheries On Penguin Foraging, Suzanne H. Alonzo, Paul Switzer, Marc Mangel

Faculty Research & Creative Activity

Summary 1. Changes in species' abundance and distributions caused by human disturbances can have indirect effects on other species in a community. Although ecosystem approaches to management are becoming increasingly prevalent, they require a fuller understand- ing of how individual behaviour determines interactions within and between species. 2. Ecological interactions involving krill are of major importance to many species within the Antarctic. Despite extensive knowledge of the ecosystem that they occupy, there is still incomplete understanding of the links between species and the effect of environmental conditions on these interactions. In this study, we extended a behavioural model used previously …

Planning For Population Viability On Northern Great Plains National Grasslands, Fred B. Samson, Fritz L. Knopf, Clinton W. Mccarthy, Barry R. Noon, Wayne R. Ostile, Susan M. Rinehart, Scott Larson, Glenn E. Plumb, Gregory L. Schenbeck, Daniel N. Svingen, Timothy W. Byer

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Broad-scale information in concert with conservation of individual species must be used to develop conservation priorities and a more integrated ecosystem protection strategy. In 1999 the United States Forest Service initiated an approach for the 1.2 x 106 ha of national grasslands in the Northern Great Plains to fulfill the requirement to maintain viable populations of all native and desirable introduced vertebrate and plant species. The challenge was threefold: 1) develop basic building blocks in the conservation planning approach, 2) apply the approach to national grasslands, and 3) overcome differences that may exist in agency-specific legal and policy requirements. Key …

Development Of A Gis Geodatabase As A Tool For Analyzing Spatial Relationships In The Species Distributions Of West Virginia Fishes, Nathan D. Bowe

Theses, Dissertations and Capstones

One of the most complete references to date of fish species distribution in West Virginia is a 1995 book entitled “The Fishes of West Virginia” (Stauffer, et al.). In this project, geographic information systems (GIS) and relational database technology have been utilized to adapt that reference into a system where spatially arranged collection site features are related to distribution data through a series of common fields among tables in a geodatabase. The geodatabase is stored in an MDB-formatted database management system (DBMS) which is readable by Microsoft Access and useful in its own right as a means to query distribution …

Wild Horses And Burros In The United States, Allen T. Rutberg

State of the Animals 2003

Treatment of wild horses and burros has improved remarkably over the last fifty years. In the mid-twentieth century, free-ranging horses and burros suffered horribly at the hands of “mustangers” who captured them at will and whim, sometimes using the most brutal of techniques, including aerial pursuit and shooting or crippling key herd members. The horses were packed into livestock trucks hurt, bleeding, and exhausted, and shipped to slaughter without stopping for rest or watering (Ryden 1999). Unprotected by law, only the good will of a few ranchers protected these abused animals. Public awareness of the plight of the wild horses …

Nest Building In Captive Gorilla Gorilla Gorilla, Kristen E. Lukas, Tara S. Stoinski, Kyle Burks, Rebecca Snyder, Sarah Bexell, Terry L. Maple

Sentience Collection

Although various aspects of gorilla nest building have been described in wild populations, nest-building behavior of captive gorillas has not been subject to much scientific review. We observed nest building in 17 gorillas during three periods: summer baseline, winter baseline, and winter treatment, in which the amount of available nesting material was doubled. We conducted observations exclusively in the indoor holding area in the hour following evening departure of animal care staff. During baseline, gorillas engaged in nest-building on 3.1% of scans and were on a constructed nest on 27.9% of scans. Overall, gorillas spent significantly more time on elevated …

Remote Sensing Estimates Of Boreal And Temperate Forest Woody Biomass: Carbon Pools, Sources, And Sinks, Jiarui Dong, Robert Kaufmann, Ranga Myneni, Compton Tucker, Pekka Kauppi, Jari Liski, Wolfgang Buermann, V. Alexeyev, Malcolm Hughs

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The relation between satellite measurements of the normalized difference vegetation index (NDVI), cumulated over the growing season, and inventory estimates of forest woody biomass carbon is estimated statistically with data from 167 provinces and states in six countries (Canada, Finland, Norway, Russia and the USA for a single time period and Sweden for two periods). Statistical tests indicate that the regression model can be used to represent the relation between forest biomass and NDVI across spatial, temporal and ecological scales for relatively long time scales. For the 1.42 billion ha of boreal and temperate forests in the Northern Hemisphere, the …

Action Education In Land Use Decisions: Student Views On Urbanization And Farmland Loss, Mindi Schneider, Charles A. Francis, Dick Esseks

CARI Extension and Education Materials for Sustainable Agriculture

Loss of prime farmland is a serious concern in the United States and around the globe. With rapid urban population increases, the activities and perceived needs of concentrated groups of people result in the swallowing of some of the most fertile lands in this country. Today we have just under 2 acres of productive farmland per person in the United States. Given the current population growth rate due to births and immigration, plus the present rate of farmland loss, World Watch Institute estimates that we will have about 0.6 acres or one-third as much farmland available per person by 2055--a …

Fire Climate Interactions And Predicting Fire Season Severity In The Mediterranean Climate Areas Of California, Southern Oregon, And Western Nevada, Alan H. Taylor, Carl N. Skinner, Andrew M. Carleton, Scott L. Stephens, Valerie Trouet, Bernd Haupt, Andrew Pierce

Joint Fire Science Program Research Project Reports

• We identified annual area burned for 37 National Forests in Washington, Oregon, and California between 1929 and 2004 from annual fire reports. Variation in area burned each year on National Forest lands is strongly related (r2 = 0.87) to total area burned in California. This indicates area burned in National Forests is a good indicator of total area burned in a state. • Four large groups of National Forests were identified that had similar temporal patterns of fire extent. Three of these groups were spatially coherent and included mainly: 1) Washington and northern Oregon; 2) northern California and California …

Land Application Setback and Buffer Requirements for NPDES Permitted Large CAFOs

Large Concentrated Animal Feeding Operation (CAFO) owners/operators are required to implement setbacks, buffers, or an alternative conservation practice on all fields to which manure is applied. This newsletter discusses the federal rules and some guidance on how the rule may be applied to land application sites. The setbacks and buffer requirements apply to large CAFOs only. Most states are authorized to implement the CAFO program and may have additional, more stringent requirements. Check with your state permitting authority to determine the requirements that apply to your operation.

Status Of Coral Reefs Of Little Cayman, Grand Cayman And Cayman Brac, British West Indies, In 1999 And 2000 (Part 1: Stony Corals And Algae), Carrie Manfrino, Bernhard Riegl, Jerome L. Hall, Robert Graifman

Marine & Environmental Sciences Faculty Articles

A benthic assessment of the isolated Cayman Islands was completed at 42 sites. Major changes in the reef community structure were documented by comparison with earlier studies. Acropora palmata and A. cervicornis, once abundant as shallow framework builders, were uncommon. Diseased stony corals were seen in >90% of the study sites, with the highest averages in Little Cayman, especially at Bloody Bay which is one of the most highly regulated marine parks in the Cayman Islands. The Montastraea annularis species complex accounted for two-thirds of the diseased corals which, along with other massive species, were affected largely by white-plague …

Protein Semi-Synthesis In Vivo, Izabela Giriat Stankiewicz

Student Theses and Dissertations

Incorporation of chemical probes into proteins is a powerful way to elucidate biological processes and to engineer novel function. This thesis describes the ligation of synthetic molecules to target proteins in an intracellular environment, and the use of semi-synthetic proteins for whole animal studies. In the first approach a cellular protein is genetically tagged with one half of a split-intein. The complementary half is linked in vitro to the synthetic probe and this fusion is delivered into cells using a transduction peptide. Association of the intein halves in the cytosol triggers protein transsplicing, resulting in the ligation of the probe …

Quantifying Ecosystem Geomorphology Of The Southern Appalachian Mountains, Scott R. Abella

Public Policy and Leadership Faculty Research

Geomorphology is a dominant factor influencing vegetation distribution in the southern Appalachians, and quantifying landform characteristics is increasingly important for forest ecosystem classification. This study used slope gradient and two previously published geomorphic indices, terrain shape index and landform index that quantify landform shape and protection, to develop a field-based landform quantification system at four study areas in the southern Appalachians. Six major landform types (ridgetops, nose slopes, linear hillslopes, coves, stream ravines, and stream bottoms) exhibited quantitatively different characteristics, and these differences among landforms were not evident when using only categorical landform descriptions (e.g., convex, concave) that have been …
