Fisheries Research Report No. 132 - A Review Of Food Availability, Sea Water Characteristics And Bivalve Growth Performance At Coastal Culture Sites In Temperate And Warm Temperate Regions Of The World, Sidney A. Saxby

Fisheries Research Reports

The suitability of a coastal area for bivalve farming, as well as the density at which bivalves can be farmed in that area, is limited by the available food supply and other environmental variables. In this review, a range of successful and marginal bivalve growing areas in temperate and warm temperate coastal areas around the world are characterised. These include areas of high food and nutrient levels, such as Saldanha Bay in South Africa, and the Seto Inland Sea, Japan, through to more oligotrophic areas, typified by parts of the South Australian coastline and the Mediterranean Sea. The latter areas …

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg

Fisheries Management Papers

The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …

The Bull Run River–Reservoir System Model, Robert Leslie Annear, Scott A. Wells

Civil and Environmental Engineering Faculty Publications and Presentations

The Bull Run watershed is located 41.8 kilometers east of Portland, Oregon in the Mt. Hood National Forest and consists of two reservoirs supplying drinking water to over 840,000 people in the Portland metropolitan area. In March 1998 Steelhead and Spring Chinook were listed as threatened in the Lower Columbia basin under the Endangered Species Act. Historical reservoir operations during the summer released no water downstream resulting in stream temperatures exceeding the state water quality standard for salmonids. CE-QUAL-W2 Version 3 is a two-dimensional water quality and hydrodynamic model capable of modeling watersheds with interconnected rivers, reservoirs and estuaries. CE-QUAL-W2 …

Examination Of Small Mammal Diversity In The Riparian Areas Of Walden, Tennessee, Forrest Brown Vanderbilt

Masters Theses and Doctoral Dissertations

Vanderbilt, Forrest B. Examination of Small Mammal Diversity in the Riparian Areas of Walden, Tennessee Thesis under the direction of Robert D. Keller, Ph.D., Assistant Professor of Biology It has been hypothesized that riparian zones are prime conservation habitats and can be used as indicators of general ecosystem health (Montgomery 1996). Riparian zones, comprising a range of habitat types, typically exhibit higher biotic diversity when compared to adjacent upland hardwood forests (Batzli 1977, Cross 1985a, Cross 1985b, Doyle 1985, Knopf et al. 1988, Doyle 1990, Naiman and Decamps 1997, Ellison and van Riper III 1998, Olson and Knopf 1998).

Sustained Evaluation Of The Effectiveness Of Detector Dogs For Locating Brown Tree Snakes In Cargo Outbound From Guam, Richard M. Engeman, Daniel S. Vice, Darryl York, Kenneth S. Gruver

United States Department of Agriculture Wildlife Services: Staff Publications

The accidental introduction of the brown tree snake (Boiga irregularis) to Guam has resulted in the extirpation of most of the island's native terrestrial vertebrates, has created a health hazard to infants and children, and has resulted in economic losses. The high brown tree snake population densities on Guam, the species' adaptations for successful dispersal, and Guam's position as a focal point for commercial and military cargo shipments have created a high level of concern that brown tree snakes could spread from Guam to colonize other vulnerable locations. Cargo inspections using teams of handlers and their detector dogs …

An Ecological Basis For Managing Giant Sequoia Ecosystems, Douglas D. Piirto, Robert R. Rogers

Natural Resources Management and Environmental Sciences

A strategy for management of giant sequoia groves is formulated using a conceptual framework for ecosystem management recently developed by Region Five of the USDA Forest Service. The framework includes physical, biological, and social dimensions. Environmental indicators and reference variability for key ecosystem elements are discussed in this paper. The selected ecosystem elements include: 1) attitudes, beliefs, and values; 2) economics and subsistence; 3) stream channel morphology; 4) sediment; 5) water; 6) fire; 7) organic debris; and 8) vegetation mosaic. Recommendations are made for the attributes of environmental indicators that characterize these elements. These elements and associated indicators will define …

Autoregressive Moving Average Models Of Crown Profiles For Two California Hardwood Species, Samantha J. Gill, Gregory S. Biging

Natural Resources Management and Environmental Sciences

Time-series Autoregressive Moving Average (ARMA) models were employed to model tree crown profiles for two California hardwood species (blue oak and interior live oak). There are three major components of these models: a polynomial trend, an ARMA model, and unaccounted for variation. The polynomial trend was used to achieve a stationary series. For these crown profiles, the use of a quadratic trend resulted in a stationary series for 60% of the profiles. A cubic trend was used for another 23%, and a quartic for 7%. It was found that 80% of the tree crown profiles could be modeled using a …

Fisheries Research Report No. 138 - Historical Diving Profiles For Pearl Oyster Divers In Western Australia, H M A Lulofs, Neil R. Sumner

Fisheries Research Reports

The annual value of the pearl oyster fishery off the north coast of Western Australia is in the vicinity of 153 million dollars. Most pearl oyster fishing occurs in the Broome area. This area is managed on a quota system with a total allowable catch of 512,000 shells in 1996, during which 511,716 shells were taken. This required 12,775 hours of dive time at a catch rate of 40 shell per hour.

Drift diving practices in the Western Australian pearling industry over the last eighteen years are described and related to the number of medical incidents. The study provides a …

A Study Of Various Thermodynamic And Wind Variables Associated With Tornadic Supercells Exhibiting Atypical Motion, Aaron Johnson

United States Department of Commerce: Staff Publications

Recent research into supercells has focused on narrowing the number of important storm processes that lead to these storms. For years it has been known that supercells generally deviate slightly to the left or right of the mean wind, but that in some rare cases, supercells move in a very atypical direction. For example, Corfidi (1998) examined the conditions present for the Jarrell, Texas tornado, which exhibited such an atypical motion, and found the environment to be extremely unstable with weak storm-relative helicity. He also found that the southwest movement of the Jarrell, TX storm was closely tied to the …

The Lower Willamette River is located in Oregon and drains a watershed covering 11500 square miles consisting of forested, agricultural, and urban lands. Inflows include treated municipal wastes and industrial effluents along with non-point sources from agricultural, silvicultural and urbanized land. The model was designed to address temperature, dissolved oxygen, algae, pH and bacteria concerns. The Corps of Engineers two-dimensional, laterally averaged, hydrodynamic and water quality model CE-QUAL-W2, Version 3 was applied. CE-QUAL-W2 consists of directly coupled hydrodynamic …

Effect Of Time Of Temperature Observation And Estimation Of Daily Solar Radiation For The Northern Great Plains, Usa, Rezaul Mahmood, Kenneth Hubbard

School of Natural Resources: Faculty Publications

Daily incident solar radiation is an important input for numerous crop growth simulation models. However, lack of recorded solar radiation is a significant impediment for most crop–climate studies. The present study aimed to overcome the problem of sparse historical data of solar radiation over the northern Great Plains. The approach was to develop a physically based solar radiation model wherein estimates were possible with minimum input data. In addition, this study investigates impacts of time of observation bias on the model formulation. The proposed model (M-H) requires measured daily range of air temperature (maximum minus minimum) and estimated daily clear-sky …

Caffeine As A Repellent For Slugs And Snails, Robert G. Hollingsworth, John W. Armstrong, Earl Campbell

United States Department of Agriculture Wildlife Services: Staff Publications

Most commercial products for snail and slug control contain either metaldehyde or methiocarb as the active ingredient, the residues of which are not permitted in food crops in the United States. We have discovered that solutions of caffeine are effective in killing or repelling slugs and snails when applied to foliage or the growing medium of plants. Because caffeine is a natural product and is classified by the United States Food and Drug Administration as a GRAS (‘generally recognized as safe’) compound, it has potential as an environmentally acceptable alternative toxicant for the control of slugs and snails on food …

Aerosolized Essential Oils And Individual Natural Product Compounds As Brown Treesnake Repellents , Larry Clark, John Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

Chemical irritants useful as repellents for brown treesnakes (Boiga irregularis) were identified. Exposure to various compounds produced a range of intensities for locomotory behavior in snakes. Essential oils comprised of 10 g liter ^-1 solutions of cedarwood, cinnamon, sage, juniper berry, lavender and rosemary each were potent snake irritants. Brown treesnakes exposed to a 2-s burst of aerosol of these oils exhibited prolonged, violent undirected locomotory behavior. In contrast, exposure to a 10 g liter^-1 concentration of ginger oil aerosol caused snakes to locomote, but in a deliberate, directed manner. We also tested specific compounds, all derivative …

Quality Control For Usda Nrcs Sm–St Network Soil Temperatures: A Method And A Dataset, Q. Steven Hu, Song Feng, Garry Schaefer

School of Natural Resources: Faculty Publications

In 1991, the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) established its Soil Moisture–Soil Temperature (SM–ST) Pilot Network consisting of 21 stations in 19 states in the contiguous United States. At each station, soil temperatures were measured at up to six different depths from 5.08 to 203.20 cm (or 2–80 in.) below the surface. Before 1997, the observations were made every 6 h, and they increased to hourly beginning in 1997. The goal of this network is to provide near–real time soil temperature and soil moisture observations in different regions across the United States for agricultural and …

Farm Systems and Economics published reports

Perth, its suburbs and adjacent semi rural and rural areas are part of the Swan-Canning catchment. Ona broad scale the Swan and Canning Rivers are part of a large drainage system that collects and drains water from across the catchment via a myriad of small channels, creeks, brooks and drains which, working together, concentrates the flow into a single water body, the Swan-Canning Estuary. This drainage system collects water both from the surface of the land and also from water, which seeps beneath the surface and moves underground.

The water may contain a considerable variety of potential pollutants, such as …

An Analysis Of Field Data For Evidence Of Anaerobic Degradation Of Pah And Btex Plumes At Manufactured Gas Plant Sites, Georgene Mortimer

Dissertations

Field data (including geology, hydrogeology, soil chemistry, groundwater chemistry, and aquifer characteristics) were analyzed at eight MGP sites located in the New Jersey Coastal Plain. These data were used to calculate biodegradation rate constants, which were then compared with laboratory microcosm data and published values. Isopleths were drawn from the field data to indicate the dominant biodegradation mechanisms at each of the sites, and stoichiometric calculations were used to determine the total capacity of the electron acceptors present to degrade the plume contaminants. In examining these data, the protocol described by the Air Force Center for Environmental Excellence (AFCEE) was …
