Nonpoint Sources And Impacts In A Small Coastal Plain Estuary: A Case Study Of The Ware River Basin, Virginia, Gary F. Anderson, Cindy Bosco Jan 1981

Nonpoint Sources And Impacts In A Small Coastal Plain Estuary: A Case Study Of The Ware River Basin, Virginia, Gary F. Anderson, Cindy Bosco

VIMS Books and Book Chapters

The Ware River Study is one of five small watershed projects sponsored by the EPA Chesapeake Bay Program. These projects are designed to provide data on nutrient and organic loadings entering the Bay over the wide range of topographies, climates, and land uses which occupy its watershed. Each provides information on a particular geographic segment of the Bay region. In particular, the Ware study is intended to document special characteristics of runoff from low relief coastal plain environments, and to document their impacts on a small estuarine receiving water.


A Preliminary Study Of Community Oxygen Metabolism In The Vicinity Of The C. P. Crane Electric Power Generating Station : Final Report, Paul L. Zubkoff Jan 1981

A Preliminary Study Of Community Oxygen Metabolism In The Vicinity Of The C. P. Crane Electric Power Generating Station : Final Report, Paul L. Zubkoff

Reports

The community metabolism of the waters in the vicinity of C. P. Crane electric power generating station is reported for two seasonal periods in 1979. The early autumn period (October) is generally characterized by warm water temperatures (20°C) and an insolation period of 11 hours; the late autumn period (December) is generally characterized by cold water temperatures (4-6°C) and an insolation period of approximately 9 hours. Both sets of observations, were taken during periods which were significantly influenced by winds. ... more.

Fate And Effects Of Experimental Oil Spills In An Eastern Coastal Plain Marsh System : Final Report, M. E. Bender, J. G. Hudgins, R. A. Jordan

Reports

The objectives of this program conducted over a four year period were to determine the ecological effects, chemical fate and microbial responses of marsh systems to crude oil spills. To conduct these studies in a manner which maximized control, large enclosures were constructed in a natural mesohaline marsh (Figure 1). Both fresh South Louisiana crude and artificially aged South Louisiana crude were studied.


Oyster Spatfall In Virginia Rivers: 1980 Annual Summary, Dexter S. Haven, Paul C. Kendall Jan 1981

Oyster Spatfall In Virginia Rivers: 1980 Annual Summary, Dexter S. Haven, Paul C. Kendall

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 from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are 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. Shells planted just before the period of maximum set have the best chance of getting a good strike.

Effluent Travel Estimates From Ships Anchored In Chesapeake Bay : A Report To The Virginia State Water Control Board, C. S. Fang, C. S. Welch, T. J. Brooks Jan 1981

Effluent Travel Estimates From Ships Anchored In Chesapeake Bay : A Report To The Virginia State Water Control Board, C. S. Fang, C. S. Welch, T. J. Brooks

Reports

As the world demand for coal has increased, the number of colliers arriving at Hampton Roads, Virginia, to load coal has exceeded the ability of the port to supply the demand. As a result, a substantial backlog of ships waiting to load coal is presently taxing the anchorage capacity of the harbor. A recent estimate is that 130 ships are waiting about 38 days each for their turn at the loading factl1t1es. In addition to the anchorages tn Hampton Roads and the lower James River, new anchorages have been opened to accomodate these ships, one on the southern side of …


The Consequences Of Nutrient Enrichment In Estuaries, Bruce J. Neilson Jan 1981

The Consequences Of Nutrient Enrichment In Estuaries, Bruce J. Neilson

Reports

A "paper study" was conducted to determine the consequences of nutrient enrichment in an estuary. First, a classification scheme was developed to assign- a "Level of Nutrient Enrichment" to a water body based on concentrations of Total Phosphorus and Total Nitrogen. The impacts of nutrient enrichment on the various uses of estuaries there were described and assessed. Finally, "safe" nutrient levels for Chesapeake Bay and its tributaries were recommended.


Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter Jan 1981

Wind Erosion In The Jerramungup Area 1980-1981, Bryan J. Goddard, M G. Humphry, D J. Carter

Resource management technical reports

An investigation of the wind erosion problem at Jerramungup was conducted by on-farm survey and Landsat interpretation from September to November 1981. Sandblasting and wind erosion were estimated to have seriousloy affected some 44,000 ha in 1980 and over 64,000 ha in 1981. The 1981 damage estimate is conservative, because a much greater area of pasture land was affected by erosion in May-July but achieved vegetative cover by later winter.

Growth And Survival Of Largemouth Bass In Newly Stocked South Dakota Impoundments, Clifton C. Stone Jan 1981

Growth And Survival Of Largemouth Bass In Newly Stocked South Dakota Impoundments, Clifton C. Stone

Electronic Theses and Dissertations

The present study was designed to evaluate the effect of five different stocking combinations and differences in climatic and morphological conditions within South Dakota on initial growth and survival of the largemouth bass (Micropertus salmoides). Forage species stocked with bass included gold shiners (Notemigonus crysoleucas), fathead minnow (Pimephales promelas), black bullhead (Ictalurus melas), and bluegill (Lepomis macrochirus). Bass only stocking was also evaluated. First eyar survival values for 16 eastern South Dakota ponds ranged from 1 to 100%, with a mean of 50.2%. Bass exhibited poorest survival when stocked with black bullheads. Analysis of variance indicated no significant difference (P …


Woodpecker Nesting Habitat In A Prairie River Woodland, J. Barry Parrish Jan 1981

Woodpecker Nesting Habitat In A Prairie River Woodland, J. Barry Parrish

Electronic Theses and Dissertations

Differences in nest site selection of the common flicker (Colaptes auratus), yellow-bellied sapsucker (Sphyrapicus varius), downy woodpecker (Picoides pubescens), and red-headed woodpecker (Melanerpes erythrocephalus) were studied on the Big Sioux River riparian forest of eastern South Dakota during 1980 and 1981. Nest site preferences were compared using two-group stepwise discriminant analysis. Randomly selected potential nest trees showing no previous signs of cavity excavation were included as control groups. The yellow-bellied sapsucker-red-headed woodpecker function was the most efficient in separating groups because both species had specific nest site preferences. Sapsuckers nested only in live green ash (Fraxinus pennsylvanica), characteristically in park-like …


Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley Jan 1981

Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley

Electronic Theses and Dissertations

Initial growth and survival rates were estimated for bluegills (Leponis macrochirus) and black bullheads (Ictalurus melas) stocked simultaneously with largemouth bass (Micropterus salmoides) in ponds throughout South Dakota. Mean first year survival for bluegills and black bullheads stocked in eastern South Dakota ponds was 28.6% and 67.7%, respectively. Differences in first year bluegill growth throughout the state were not detected. Total lengths for bluegills averaged 52.4 mm after one growing season statewide and 137.1 mm after two growing seasons in southeastern South Dakota ponds. Significant (P<.05) geographical differences in first year growth of black bullheads were detected with mean lengths ranging from 67.7 mm in northwest ponds to 115.5 mm in southeast ponds. The average total length for black bullheads after two growing season in southeastern South Dakota ponds was 215.2 mm. The combined effects of pH, turbidity, and bicarbonate alkalinity accounted for 67.5% of the variation in first year bluegill growth. The pond parameters total number of growing days, fish present prior to stocking, and pond surface area when combined accounted for 73.9% of the variation in first year black bullhead growth. Differences in bluegill relative weight values were not detected throughout South Dakota; the average for the state was 105.2. Mean black bullhead condition factors (K) for fish with total lengths between 128 and 191 mm were 1.85 and 1.45 for pre- and post-spawning periods, respectively. Bullheads probably spawned between 29 May and 26 June 1980.


Movement And Distribution Of Esocids And Forage Fishes In A Power Plant Cooling Reservoir, Douglas T. Henley Jan 1981

Movement And Distribution Of Esocids And Forage Fishes In A Power Plant Cooling Reservoir, Douglas T. Henley

Electronic Theses and Dissertations

One Muskellunge (Esox masquinongy) and 2 northern pike (E. Lucius) were surgically implanted with untrasonic transmitters and tracked in a South Dakota cooling reservoir from June 1979 to June 1980. The fishes inhabited the intake area of the reservoir during the summer (temperature range, 27.5 – 31.5˚ C) and the discharge area during the winter (temperature range, 4.5 – 31.5˚C). In the spring and fall, the fishes were located throughout the reservoir (temperature range, 12.0 – 28.5˚C). Highest rates of movement for the esocids were recorded during the spring (675 – 1,100 m/day). The lowest rates were recorded during late …

Home Range, Home Range Expansion, Dispersal, And Mortality Of Juvenile Red Foxes In Southeastern South Dakota, Floyd M. Demaray

Electronic Theses and Dissertations

Data from aerial and landowner surveys showed that red fox (Vulpes vulpes) families on the Sinai study area decreased from 13 (5.2 per township) in 1976 to 11 (4.4 per township) in 1977. The majority (88%) of the active red fox dens was located in pastures and idle lands although these cover types constituted only 24% of the available cover. Twenty-nine juveniles and 3 adults were captured and marked during spring, 1976. Trappers and hunters returned 62% of the tags placed on juvenile foxes. During spring, 1977, 15 juveniles and 2 adult red foxes were marked. Three juveniles were subsequently …

The Quality Outdoor Recreation Component In Multi-Purpose Conservation Areas: A User Assessment Devised, And Applied To Pinehurst Lake Conservation Area, Gerald Carl Thomas Jan 1981

The Quality Outdoor Recreation Component In Multi-Purpose Conservation Areas: A User Assessment Devised, And Applied To Pinehurst Lake Conservation Area, Gerald Carl Thomas

Theses and Dissertations (Comprehensive)

Recreational demand for out-of-doors space and facilities continues to increase into the 1980’s. Accordingly, multi-purpose conservation areas, by the nature of their designations, require ongoing assessment of the attributes which determine the quality of the recreational experience they afford.

A problem with the master planning process for these multi-use areas is that in the past, little or no consideration has been given to user-recreationist input in the development stages of the master plans. The purpose of this study is to devise a method of assessing user satisfaction towards the recreational quality available at multi-use conservation areas, and to show how …


The Distribution And Relative Abundance Of Aquatic Oligochaeta In The Upper Cache River System, Southern Illinois, In Relation To Water Quality, Mark Julian Wetzel Jan 1981

The Distribution And Relative Abundance Of Aquatic Oligochaeta In The Upper Cache River System, Southern Illinois, In Relation To Water Quality, Mark Julian Wetzel

Masters Theses

Species composition, distribution, abundance, and water quality relationships of aquatic oligochaetes occurring in the upper Cache River system, southern Illinois were investigated. Forty-two taxa of oligochaetes including 16 naidids, 22 tubificids and representatives of the families Aeolosomatidae, Branchiobdellidae, Enchytraeidae, and Lumbriculidae were collected. Four species of oligochaetes new to Illinois, Limnodrilus psammophilus Loden, L. rubripenis Loden, Psammoryctides (Spencerius) californianus Brinkhurst, and Haemonais waldvogeli Bretscher were collected during this study. Another species of Limnodrilus new to science is reported here, as yet undescribed. The thesis that aquatic oligochaetes can be used as true water quality indicator organisms is rejected. It is …
