National List Of Plant Species That Occur In Wetlands: 1988, Nevada, Porter B. Reed, Jr.

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

The National List of Plant Species That Occur in Wetlands: 1988 (National List) represents the combined efforts of many biologists over the last decade to define the wetland flora of the United States. The National List has undergone a number of revisions resulting from intensive review by regional ecologists. National, regional and State lists are being distributed to provide users with the most current information. We welcome and encourage modification and improvement of the National List. Refinement of the National List will occur continually, reflecting increased knowledge in Indicator assignments, taxonomy, and geographic distribution. We anticipate that further refinement of …

The Status Of Three Uncommon Salamanders (Amphibia: Caudata) In Iowa, Jeffery D. Camper

Journal of the Iowa Academy of Science: JIAS

The smallmouth salamander [Ambystoma texanum (Matthes)], blue-spotted salamander (Ambystoma laterale Hallowell), and central newt [Notophthalmus viridescens louisianensis (Wolterstorff)] were studied in Iowa from fall 1982 through summer 1984. All three species have declined in abundance in Iowa. A. texanum is more abundant and widespread than was previously suspected, but is declining due to habitat destruction. Apparently, only two populations of A. laterale remain in Iowa. N. v. louisianensis has also declined due to habitat destruction, with only three populations known. All three species require ponds in or adjacent to forest. A. ta was found primarily in riparian …

Wetland Characteristics Of Avian Cholera Outbreaks And Surface Water Transfer In The Nebraska Rainwater Basin Area, Brian J. Smith

Electronic Theses and Dissertations

Avian Cholera (Pateurella multocida) has infected and killed thousands of migrating waterfowl each year since 1975 in Nebraska’s rainwater basin area. Disease outbreaks in migrating waterfowl populations just prior to the nesting season are of concern to biologists. Feedlots and itner-wetland basin surface water transfer mechanisms of the avian cholera causative agent, P. multocida, were investigated using remote sensing techniques. Wetland basin characteristics (classification type, adjacent landuse, basin landuse, and basin densities) were also investigated for relationships to 1981 avian cholera outbreaks. No surface drainage relationships were found that would permit the transfer of P. multocida from one wetland basin …

Paleontological Results From Ocean Drilling Program Leg 101, David K. Watkins, Eric Fourcade, R. Mark Leckie, Allan J. Melillo, Amanda A. Palmer, Joost W. Verbeek, Jacques Butterlin, Renée Damotte, Claude Guernet, Edwige Masure, Michael J. Moran

Department of Earth and Atmospheric Sciences: Faculty Publications

Leg 101 of the Ocean Drilling Program recovered Albian through Holocene sediments from a variety of carbonate depositional environments. Data from four microplanktonic groups (calcareous nannofossils, planktonic foraminifers, radiolarians, and dinoflagellates) and four benthic groups (larger foraminifers, smaller benthic foraminifers, ostracodes, and sponge spicules) yield a biostratigraphic and paleoecologic framework for these varied sediments. Winnowed, skeletal-planktonic foraminiferal packstones and grainstones from the central Straits of Florida (Site 626) reflect a late Oligocene to Holocene history of sporadic sedimentation greatly influenced by strong bottom-current activity. Neogene to Quaternary sediments from two carbonate-slope transects (Sites 627 to 633) indicate significant slope accretion …

Carbon Dioxide Emissions And Fossil Fuel Consumption A Canadian Perspective, John Peter Doucet

Theses and Dissertations (Comprehensive)

The potential climate change due to increased loading of carbon dioxide in the atmosphere has emerged as one of the most significant environmental threats of the late twentieth century. An analysis of a variety of feasible energy demand scenarios for Canada indicates that if we continue to consume the same types and proportions of fuels as we do today, the expected demand for energy in the year 2005 would yield carbon dioxide emissions up to 52.5 per cent greater than that of 1985. On the other hand, if Canada were to alter the types and quantities of fuels required to …

Evaluation Of Possible Reproductively Mediated Character Displacement In The Crayfishes, Orconectes Rusticus And O. Sanbornii, Mark J. Butler Iv

Biological Sciences Faculty Publications

Orconectes rusticus is replacing several species of crayfishes in north-central and northeastern North America, including O. sanbornii in Ohio. Recent evidence suggests that the species replacements may be driven by asymmetrical reproductive success favoring O. rusticus. Nonetheless, some sympatric associations appear locally persistent. Because crayfish demonstrate size assortative mating and there is a disparity in the sizes of the species, further divergence in the sizes of the species in sympatry could enhance reproductive isolation, ultimately providing a mechanism for character displacement. To test this hypothesis the size differentials between crayfish collected from allopatric and sympatric populations in east-central Ohio …

Interbasin Water Transfers: An Appropriate Management Practice For The Great Lakes?, David M. Krentz

Theses and Dissertations (Comprehensive)

Regional water deficiencies exist in North America, and proposals have been advanced to ‘correct’ these by transferring water from regions where it is relatively abundant to regions where it is relatively scarce. Many of these proposals identify the Great Lakes as either a potential source of the water, or as a ‘distribution centre’ into which water may be transferred and subsequently removed to regions experiencing deficiencies. Although the Great Lakes contain a very large amount of fresh water, most of it is required in place, and so many not be removed. The Great Lakes Basin is heavily populated and highly …

The Onset Of Spring Melt In First-Year Ice Regions Of The Arctic As Determined From Scanning Multichannel Microwave Radiometer Data For 1979 And 1980, Mark R. Anderson

Department of Earth and Atmospheric Sciences: Faculty Publications

Sea ice ablation is an important physical process affecting the global climate system. During the Arctic melt season, rapid changes occur in both sea ice surface conditions and the extent of ice. These changes alter the albedo and vary the surface energy budget. Understanding variations in Arctic sea ice is critical for global climate studies. This paper investigates the spring onset of melt in the Arctic seasonal sea ice zone through analysis of melt signatures derived from Nimbus 7 scanning multichannel microwave radiometer data. Satellite-derived melt signatures, determined by 18- and 37-GHz vertical brightness temperatures, are associated with the initial …

Geomorphic Character, Age And Distribution Of Rock Glaciers In The Olympic Mountains, Washington, Steven Paul Welter

Dissertations and Theses

Rock glaciers are tongue-shaped or lobate masses of rock debris which occur below cliffs and talus in many alpine regions. They are best developed in continental alpine climates where it is cold enough to preserve a core or matrix of ice within the rock mass but insufficiently snowy to produce true glaciers. Previous reports have identified and briefly described several rock glaciers in the Olympic Mountains, Washington, but no detailed integrative study has been made regarding the geomorphic character, age, and distribution of these features.

The purpose of this study is two-fold. First, surface sediment fabric analysis and relative and …

Nitrate Pollution Of Ground Water In Glacial Sediments Underlying A Fertigated Site In Kalamazoo County, Michigan, Michael Wireman

Masters Theses

In the central part of Schoolcraft Township high yield corn crops are successfully grown on soils developed on permeable outwash deposits. The high yields are made possible with the utilization of modern irrigation techniques and regular application of nitrogen fertilizer.

Excess nitrogen which moves past the root zone is easily converted to nitrate and leached to the shallow ground water. Water quality data from 103 ground-water samples in the vicinity of a 160-acre corn field in Section 11 clearly indicate that nitrate concentrations in the ground water beneath the field and beneath the area immediately downgradient from the field are …

The Military Sealift Command: Their Potential Role In Providing Military Logistic Support To The Persian Gulf, Kevin W. Nicholas

Marine Affairs Theses and Major Papers

The ultimate goal of the U.S. Maritime Strategy is to project power into all the oceans of the world. By projecting power over this vast a geographic area, the U.S. is able to provide a deterrent force that will inhibit the development of a significant hostile military action, anywhere in the world. The ability to support this global peacekeeping force hinges on the capability of the U.S. to provide a strong logistic support organization. From a waterborne perspective, the Indian Ocean is the one geographic area of the world that presents the greatest logistic challenge. The U.S. Navy and the …
