Energetic Adaptations Along A Broad Latitudinal Gradient: Implications For Widely Distributed Assemblages, Jeffrey Gibson Miner, James E. Garvey, Dennis R. Devries, Russell A. Wright

Biological Sciences Faculty Publications

Most community-based models in ecology assume that all individuals within a species respond similarly to environmental conditions and thereby exert identical effects as consumers or prey. Rather, individuals differ among systems, with important implications for population demographics and community interactions. For widely distributed assemblages made up of poikilotherms with high first-year mortality, species-specific differences in growth reaction norms as affected by both temperature and genotype will influence biotic interactions. For a broadly distributed fish assemblage, first-year growth does not vary with latitude for a planktivorous prey species, but declines with increasing latitude for a terminal piscivore. Size-based competitive interactions between …

Understanding Policy Change In Developing Countries: The Spheres Of Influence Framework, Paul F. Steinberg

All HMC Faculty Publications and Research

National policy reform is a prerequisite for improved stewardship of the global environment and figures prominently among the goals of international environmental diplomacy and transnational advocacy campaigns. Yet research on global environmental politics has proceeded absent models of policy change in developing countries, where most of the planet's people, land, and biological diversity are found. In this article I present a theoretical framework to explain the domestic responses of developing countries to global environmental concerns. Drawing on research in Costa Rica and Bolivia, I situate the impact of global environmentalism in the context of complex, decades-long domestic struggles to create …

Geographic Information System Methodologies To Evaluate Relationships Between Land Use And Groundwater Quality In South Central Kentucky, Rhonda Pfaff

Masters Theses & Specialist Projects

The development of Geographic Information System (GIS) technology has provided techniques for a holistic approach to the study of karst groundwater contamination. While karst groundwaters supply water to a large percentage of the earth's population, its complex environments often have lacked the scientific examination and conservation measures typical of non-karst regions. In this study, GIS methodologies were explored to examine the relationships between land-use and water quality in karst watersheds. Eight watersheds throughout southern and western Kentucky were examined. The study areas included the Mammoth Cave Karst Aquifer, which is the watershed that drains the Mammoth Cave System, and seven …

Five-Member Gene Family Of Bartonella Quintana, Michael F. Minnick, Kate N. Sappington, Laura S. Smitherman, Siv G. E. Andersson, Olof Karlberg, James A. Carroll

Biological Sciences Faculty Publications

Bartonella quintana, the agent of trench fever and an etiologic agent of bacillary angiomatosis, has an extraordinarily high hemin requirement for growth compared to other bacterial pathogens. We previously identified the major hemin receptor of the pathogen as a 30-kDa surface protein, termed HbpA. This report describes four additional homologues that share approximately 48% amino acid sequence identity with hbpA. Three of the genes form a paralagous cluster, termed hbpCAB, whereas the other members, hbpD and hbpE, are unlinked. Secondary structure predictions and other evidence suggest that Hbp family members are beta-barrels located in the outer membrane and contain eight …

The B-Subunit Of The Arabidopsis G Protein Negatively Regulates Auxin-Induced Cell Division And Affects Multiple Developmental Processes, Hemayet Ullah

Department of Biology Faculty Publications

Plant cells respond to low concentrations of auxin by cell expansion, and at a slightly higher concentration, these cells divide. Previous work revealed that null mutants of the alpha-subunit of a putative heterotrimeric G protein (GPA1) have reduced cell division. Here, we show that this prototypical G protein complex acts mechanistically by controlling auxin sensitivity toward cell division. Loss-of-function G protein mutants have altered auxin-mediated cell division throughout development, especially during the auxin-induced formation of lateral and adventitious root primordia. Ectopic expression of the wild-type Galpha-subunit phenocopies the Gbeta mutants (auxin hypersensitivity), probably by sequestering the Gbetagamma-subunits, whereas overexpression of …

Maine Horseshoe Crab (Limulus Polyphemus) Spawning Surveys, 2003, Susanne Y. Schaller, Peter Thayer, Sherry Hanson

Publications

Maine spawning surveys of horseshoe crabs (Limulus polyphemus) continued for a third season in 2003. Survey sites were located in Yarmouth, Brunswick (2 sites), Woolwich, Nobleboro, Damariscotta, Sedgwick, Franklin and Sullivan. The purpose of this project is to establish quantitative baseline data on horseshoe crab populations in Maine as a basis for management of this species. The 2003 season recorded cooler than normal water temperatures through the end of May, which resulted in negligible activity during the initial historical May spawning period. Warmer water temperatures in June supported normal levels of spawning activity, as documented by the June counts. The …

Terrain Influences On Severe Convective Storms Along The Pine Ridge From East Central Wyoming To Northwest Nebraska, Richard Bann, Michael Weiland, Ray Mcanelly

United States Department of Commerce: Staff Publications

Severe convective weather in the warm season is a common occurrence in the high plains. The storms in the high plains are produced primarily by synoptic and mesoscale features which have been described by Doswell (1980) and Maddox et al (1981). In addition to the weather parameters involved in producing severe convective weather, local terrain can also be a factor. The effects of the large scale Rocky Mountains on development of severe thunderstorms are well known. Since the early to mid 1980s, small scale terrain has been shown to have an effect on the development of severe convective weather, primarily …

Gray Whales Off Sakhalin Island, Russia: June – September 2001: A Joint U.S. – Russia Scientific Investigation, David W. Weller, Alexander M. Burdin, Amanda L. Bradford, Grigory A. Tsidulko, Yulia V. Ivashchenko, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Numerous species of marine mammals inhabit the Sea of Okhotsk. Two of the most endangered populations of large whales in the world; the Okhotsk Sea bowhead whale (Balaena mysticetus) and the western North Pacific (Okhotsk-Korean) gray whale are known to occur in this sea (Brownell et al., 1997; Clapham et al., 1999). Concerns regarding the status of these whale populations have been intensified by the onset of offshore oil and gas development programs in Okhotsk waters. Anthropogenic activities related to oil and gas exploration off the northeastern Sakhalin Island shelf include geophysical seismic surveying, drilling and production operations, …

Detection Of Cracks At Rivet Holes In Thin Plates Using Lamb-Wave Scanning, Roberto A. Osegueda, Vladik Kreinovich, Soheil Nazarian, Enrique Roldan

Departmental Technical Reports (CS)

This paper describes a Lamb-wave scanning method for the detection of notches simulating cracks at rivet holes in thin plates. The approach requires the generation of an ultrasonic So-Mode Lamb wave using an incident transmitter excited with a tone burst centered at a near non-dispersive frequency. Area scans are performed of a plate with a hole with a notch to generate times series information which is used to create animations illustrating the wave propagation characteristics. The time series are subject to a sifting process to obtain intrinsic mode functions which contain narrow frequency banded information of the signals. The Hilbert-Huang …

A Comprehensive Review Of The Ecological And Human Social Effects Of Artificial Feeding And Baiting Of Wildlife, L. Dunkley, M.R.L. Cattet

Canadian Cooperative Wildlife Health Centre: Newsletters and Publications

In recent years, events within Canada and the United States have drawn attention to potential negative consequences of feeding and baiting wild animals, especially enhanced transmission of infectious diseases such as bovine tuberculosis and chronic wasting disease. This report was prepared to gather available science-based information on the ecological and human social effects of artificial feeding and baiting of wildlife into one readily accessible document. The contracting agencies, Parks Canada and Saskatchewan Environment, recognize that an objective review of existing literature may help to answer questions and concerns within and outside the agencies, and help to guide subsequent decision-making concerning …

Climatic Influences On Riverine Nitrate Flux: Implications For Coastal Marine Eutrophication And Hypoxia, Dubravko Justic, R. Eugene Turner, Nancy N. Rabalais

Faculty Publications

The average nitrate flux of the lower Mississippi River increased 3.3-fold between 1954–1967 and 1983–2000. During the same time period, the average nitrate concentration increased 2.3-fold while the average discharge increased 40%. Partitioning of the observed trend in nitrate flux among the two flux components, nitrate concentration and discharge, revealed that about 80% of the observed increase in flux could be explained by the increase in nitrate concentration. This indicates that a historical increase in the anthropogenic nutrient inputs has had a far greater impact on the lower Mississippi River nitrate flux than a change in climate. The influence of …

Habitat Utilization By Bottlenose Dolphins (Tursiops Truncatus) In Biscayne Bay, Florida, Christine A. Hudak

HCNSO Student Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) exhibit variable distribution patterns, depending upon their geographic location. Habitat utilization patterns in Biscayne Bay, Florida, were examined using the Biscayne Bay Bottlenose Dolphin Photo-ID database obtained from the National Oceanic and Atmospheric Administration (NOAA) Southeast Fisheries Science Center (SEFSC) Miami Laboratory. Habitat coverages in Biscayne Bay were obtained from the Atlas of Marine Resources Version 1.3B CD and the Biscayne Bay National Park CD. Dolphin sightings were overlaid on the habitat coverages using GIS Arcview software.

The effects of habitat, season, behavior, zone (sectioned area of Biscayne Bay), and depth on patterns …

Enterobius Vermicularis: Ancient Dna From North And South American Human Coprolites, Alena M. Iñiguez, Karl J. Reinhard, Adauto Araújo, Luiz F. Ferreira, Ana Carolina P. Vicente

School of Natural Resources: Faculty Publications

A molecular paleoparasitological diagnostic approach was developed for Enterobius vermicularis. Ancient DNA was extracted from 27 coprolites from archaeological sites in Chile and USA. Enzymatic amplification of human mtDNA sequences confirmed the human origin. We designed primers specific to the E. vermicularis 5S ribosomal RNA spacer region and they allowed reproducible polymerase chain reaction identification of ancient material. We suggested that the paleoparasitological microscopic identification could accompany molecular diagnosis, which also opens the possibility of sequence analysis to understand parasite-host evolution.

Researcher Liability For Negligence In Human Subject Research: Informed Consent And Researcher Malpractice Actions, Roger L. Jansson

Washington Law Review

Two sets of federal regulations, the "Common Rule" and Food and Drug Administration (FDA) regulations, govern human subject research that is either federally-funded or involves FDA regulated products. These regulations require, inter alia, that: (1) researchers obtain informed consent from human subjects, and (2) that an Institutional Review Board (IRB) independently review and approve the research protocol. Although the federal regulations do not provide an express cause of action against researchers, research subjects should be able to bring informed consent and malpractice actions against researchers by establishing a duty of care and standard of care. Researchers owe human subjects a …

Structure Of The Proline Dehydrogenase Domain Of The Multifunctional Puta Flavoprotein, Yong Hwan Lee, Shorena Nadaraia, Dan Gu, Donald F. Becker, John J. Tanner

Faculty Publications

The PutA flavoprotein from Escherichia coli plays multiple roles in proline catabolism by functioning as a membrane-associated bi-functional enzyme and a transcriptional repressor of proline utilization genes. The human homolog of the PutA proline dehydrogenase (PRODH) domain is critical in p53-mediated apoptosis and schizophrenia. Here we report the crystal structure of a 669-residue truncated form of PutA that shows both PRODH and DNA-binding activities, representing the first structure of a PutA protein and a PRODH enzyme from any organism. The structure is a domain-swapped dimer with each subunit comprising three domains: a helical dimerization arm, a 120-residue domain containing a …
