Case 3270: Isometrinae Clark, 1917 (Ecinodermata, Crinoidea): Proposed Emendation Of Spelling To Isometrainae To Remove Homonymy With Isometrinae Kraepelin, 1891 (Arachnida, Scorpiones), Victor Fet, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

The purpose of this application, under Articles 55 and 29 of the Code, is to remove the homonymy between the crinoid subfamily name ISOMETRINAE Clark, 1917 (type genus Isometra Clark, 1908; family ANTEDONIDAE) and the scorpion subfamily name ISOMETRINAE Kraepelin, 1891 (type genus Isometrus Ehrenberg in Hemprich & Ehrenberg, 1828; family BUTHIDAE). It is proposed that the entire generic name of Isometra should be adopted as the stem, so that the correct spelling of the crinoid subfamily will become ISOMETRAINAE Clark, 1917.

Heat-Shock Protein 70 (Hsp70) As A Biochemical Stress Indicator: An Experimental Field Test In Two Congeneric Intertidal Gastropods (Genus: Tegula), Lars Tomanek, Eric Sanford

Biological Sciences

Although previous studies have demonstrated that heat-shock protein 70 (Hsp70) can be induced by environmental stress, little is known about natural variation in this response over short time scales. We examined how Hsp70 levels varied over days to weeks in two intertidal snail species of the genus Tegula. Sampling was conducted both under naturally changing environmental conditions and in different vertical zones on a rocky shore. The subtidal to low-intertidal T. brunnea was transplanted into shaded and unshaded mid-intertidal cages to assess temporal variation in Hsps under conditions of increased stress. For comparison, the low to mid-intertidal ,T. …

Environmental Enrichment And Prior Experience Of Live Prey Improve Foraging Behaviour In Hatchery-Reared Atlantic Salmon, C. Brown, T. Davidson, K. Laland

Aquaculture Collection

Atlantic salmon salmo salar L. parr were reared for 3 months under standard hatchery conditions or in a structurally enriched tank (containing plants, rocks and novel objects). Half of each of these fish had prior exposure to live prey in the form of live bloodworm while the other half were fed hatchery-pellets. After 12 days all fish were tested on a novel live prey item (brine shrimp). A significant interaction between the two factors (prior exposure to live prey and rearing condition) revealed that foraging performance was only enhanced in fish that had been reared in a complex environment and …

Groundwater Test Pumping In The Tambellup Townsite, Louise Hopgood

Resource management technical reports

Previous studies have concluded that the township of Tambellup is underlain by a perched aquifer. Test pumping and groundwater modelling indicated that groundwater pumping may be an effective way of protecting townsite infrastructure by lowering the water table beneath the town. This report presents results of the test pumping and provides likely bore yields, prediction of pumping influence and likely optimum production bore spacing.

Vertebrate Information Compiled By The Utah Natural Heritage Program: A Progress Report, State Of Utah Department Of Natural Resources, William R. Bosworth Iii, Division Of Wildlife Resources, Utah Natural Heritage Program

All U.S. Government Documents (Utah Regional Depository)

The Utah Natural Heritage Program (UNHP) assimilates and synthesizes information concerning rare species for use in land management and species conservation applications. This information is maintained in the UNHP database and includes both species-level information—e.g., assessments of species conservation status from a statewide perspective—and population-level information, which includes GIS coverages for species of high conservational interest. Beginning in 1996 an effort to develop information in the UNHP database for animal species was funded by the Utah Reclamation, Mitigation, and Conservation Commission under authority of the Central Utah Project Completion Act. Initial efforts focused on assigning conservation priority ranks. Several factors—comprising …

Semantic (Web) Technology In Action: Ontology Driven Information Systems For Search, Integration, And Analysis, Amit P. Sheth, Cartic Ramakrishnan

Kno.e.sis Publications

Semantics is seen as the key ingredient in the next phase of the Web infrastructure as well as the next generation of information systems applications. In this context, we review some of the reservations expressed about the viability of the Semantic Web. We respond to these by identifying a Semantic Technology that supports the key capabilities also needed to realize the Semantic Web vision, namely representing, acquiring and utilizing knowledge. Given that scalability is a key challenge, we briefly review our observations from developing three classes of real world applications and corresponding technology components: search/browsing, integration, and analytics. We distinguish …

Mitogenic Effect Of Bartonella Bacilliformis On Human Vascular Endothelial Cells And Involvement Of Groel, Michael F. Minnick, Laura S. Smitherman, D. Scott Samuels

Biological Sciences Faculty Publications

Bartonellae are bacterial pathogens for a wide variety of mammals. In humans, bartonellosis can result in angioproliferative lesions that are potentially life threatening to the patient, including bacillary angiomatosis, bacillary peliosis, and verruga peruana. The results of this study show that Bartonella bacilliformis, the agent of Oroya fever and verruga peruana, produces a proteinaceous mitogen for human vascular endothelial cells (HUVECs) that acts in a dose-dependent fashion in vitro with maximal activity at >72 h of exposure and results in a 6- to 20-fold increase in cell numbers relative to controls. The mitogen increases bromodeoxyuridine (BrdU) incorporation into HUVECs …

The Effect Of Prescribed Burns On Cation Exchange Capacity In An Oak Savanna, Christopher Michael Gentry

All-Inclusive List of Electronic Theses and Dissertations

The Indiana Department of Natural Resources estimates that fire-maintained, tallgrass savannas once covered approximately 15% oflndiana. During the 1800's, settlers cleared savannas for their rich soils, which are well suited for agricultural use, and fire was suppressed from the remaining savannas because of the threat to farmland. Today, prescribed bums are being used in savannas as a management tool to reduce competition from non-native species, encourage community density, and promote patch dynamics. This research examines how fire affects Cation Exchange Capacity (CEC) in post fire soil samples. CEC is an important soil characteristic that helps to describe soil fertility. With …

Chemistry Of Cirsium And Carduus: A Role In Ecological Risk Assessment For Biological Control Of Weeds?, Ingrid E. Jordon-Thaden, Svata M. Louda

School of Biological Sciences: Faculty Publications

Prediction of host plant range and ecological impact of exotic phytophagous insects, such as insects for classical biological control of weeds, represents a major challenge. Recently, the flowerhead weevil (Rhinocyllus conicus Fröl.), introduced from Europe into North America to control exotic thistles (Carduus spp.), has become invasive. It feeds heavily on some, but not all species of native North American thistles (Cirsium spp.). We hypothesized that such non-target use among native plants could be better predicted by knowledge of characteristic chemical profiles of secondary compounds to supplement the results of host specificity testing. To evaluate this hypothesis, …

School of Biological Sciences: Faculty Publications

The purpose of this data set was to compile body mass information for all mammals on Earth so that we could investigate the patterns of body mass seen across geographic and taxonomic space and evolutionary time. We were interested in the heritability of body size across taxonomic groups (How conserved is body mass within a genus, family, and order?), in the overall pattern of body mass across continents (Do the moments and other descriptive statistics remain the same across geographic space?), and over evolutionary time (How quickly did body mass patterns iterate on the patterns seen today? Were the Pleistocene …

New in this Seasonal Report, direct from the American Ornithologists' Union (along with Wilson's Snipe, Rock Pigeon, etc.), is the modified checklist order, featuring geese, swans, and ducks at the beginning, followed by gallinaceous birds, then resuming the familiar order with loons.

Perhaps the most important use for these reports, in addition to their incorporation into the Southern Great Plains Region summary in North American Birds, is the noting of significant avian events in Nebraska. Some are of obvious importance, but the meaning of others is obscure, perhaps only to be revealed as subsequent reports show a trend, or …
