Oyster Spatfall In Virginia Rivers: 1985 Annual Survey, James Whitcomb
Oyster Spatfall In Virginia Rivers: 1985 Annual Survey, James Whitcomb
Reports
The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung qn wire and suspended from stakes on public and private beds. The number of spat on shells is counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.

Reports
This report describes work performed by the Virginia Institute of Marine Science, School of Marine Science of the College of William and Mary, Gloucester Point, VA, to document the existing preoperational conditions at four locations in the Chesapeake Bay selected as possible dredged material disposal areas for the deepening of the Baltimore Channel. The work was sponsored by the Baltimore District Corps of Engineers.
The objectives of this work were at each of the four potential disposal sites:
1 -document the surface (0-15 em) sediment conditions spatially and temporally
2 - document macrobenthic communities spatially and temporally.
3 - empty …

Multiple Trophic Levels In Soft-Bottom Communities, John A. Commito, William G. Ambrose Jr.
Environmental Studies Faculty Publications
In order to assess the general applicability of recent field experiments with predatory infauna, we searched the literature and found 48 well-documented cases of infaunal consumption by such predators. In 63 % of the cases detailed enough to make a determination, the predators ate other predators. Multiple trophic levels within the infauna are probably a common feature of many soft-bottom communities.

Physical Properties Of Tar Sand Tailings That Influence Their Ability To Sustain Plant Growth, Timothy Cole
Physical Properties Of Tar Sand Tailings That Influence Their Ability To Sustain Plant Growth, Timothy Cole
Masters Theses & Specialist Projects
The mining of bituminous sandstone rock for the purpose of extracting bitumen has created a need for reclamation. One such mine is located in northern Logan County. Their mining operation involves removing large sections of sandstone, which is impregnated with bitumen, and crushing it to sand-sized material. The sand-sized material is then mixed with organic solvents which extract the bitumen. Once separated, the bitumen is stored for future refinement and the spent sand is stockpiled for later disposal.
The spent sands or waste material are referred to as tar sand tailings. These tailings have particular properties which make reclamation efforts …

Western Water Law in Transition (Summer Conference, June 3-5)
Conference organizers and/or faculty included University of Colorado School of Law professors James N. Corbridge, Jr., Lawrence J. MacDonnell, Richard B. Collins, David H. Getches and Charles F. Wilkinson.
The prior appropriation doctrine has governed the allocation and use of water in the western United States since the 1850s. The shifting nature of water demand is bringing about changes in the traditional legal system. This conference will consider the fundamental principles of the prior appropriation doctrine together with the important new developments in the law now underway throughout the West.

Wood Of Giant Sequoia: Properties And Unique Characteristics, Douglas D. Piirto
Wood Of Giant Sequoia: Properties And Unique Characteristics, Douglas D. Piirto
Natural Resources Management and Environmental Sciences
Wood properties of giant sequoia (Sequoia gigantea [Lindl.] Decne.) were compared with those for other coniferous tree species. Wood properties such as specific gravity, various mechanical properties, extractive content, and decay resistance of young-growth giant sequoia are comparable to or more favorable than those of coast redwood (Sequoia sempervirens [D. Don] Endl.). It is recommended that giant sequoia be considered for planting stock in managed production forests to increase future supplies of wood having the characteristics so highly valued in coast redwood and other decay-resistant species

The report commences with a discussion of the diffusion and adoption model, and illustrates some of the research observations and practical outcomes that have emerged in recent years, An overview of social network research is presented as a means of understanding communication exchanges and providing data relevant to the diffusion debate. The communication and adoption studies are then reported in three separate sections in the order they were conducted. (A map of the location of the survey areas is shown in Figure I ) . The objectives, survey method, results and a summary are presented for each study.

The objectives of this study were:
1. to determine the areal extent of discharged materials within each of the rivers using the aluminum:silicon ratio as an indicator;
2. to evaluate the benthic invertebrate communities within each of the rivers;
3. to determine whether there are differences in the productivity of the benthic algal and planktonic communities which can be attributed to the discharge of alum sludge in each river;
4. to evaluate the condition of the marsh communities in each river near the filtration plant;
5. to review historical biological data for the Poquoson and Warwick Rivers and to relate …

Classification, Paleoecology, And Biostratigraphy Of Crinoids From The Stull Shale (Late Pennsylvanian) Of Nebraska, Kansas, And Iowa, Roger K. Pabian, Harrell L. Strimple
Bulletin of the University of Nebraska State Museum
Thirteen species of crinoids representing the families Diphuicrinidae, catacrinidae, Pirasocrinidae, Erisocrinidae, Cromyocrinidae, Cymbiocrinidae, Scytalocrinidae, and Ampelocrinidae have been collected from the Stull Shale Member of the Kanwaka Formation in the Shawnee Group of the Virgil Series (Upper Pennsylvanian) from near Weeping Water and Plattsmouth, Nebraska, and near Pacific Junction, Iowa. Exposures of the Stull Shale near Melvern, Kansas, have yielded 14 species of crinoids representing the families Diphuicrinidae, Catacrinidae, Pirasocrinidae, Lophocrinidae Allagecrinidae, Cymbiocrinidae, Erisocrinidae, Apographiocrinidae, and Stellarocrinidae. All but two of the species present in the Stull Shale have been previously reported from other stratigraphic horizons, including the Vinland Shale …
