The Identification, Distribution, And Status Of The Threatened Dismal Swamp Shrew (Sorex Longirostris Fisheri), Thomas M. Padgett
Biological Sciences Theses & Dissertations
Southeastern shrews (Sorex longirostris) were trapped throughout southeastern Virginia and northeastern North Carolina to determine if any morphological characters could
be identified that would aid in the identification and distribution of the threatened subspecies Sorex l._ fisheri, endemic to the Great Dismal Swamp, the more upland nominate subspecies Sorex l. longirostris, and possible intergrades between the two subspecies. Animals were classified a priori into three groups, based on their location of capture. Animals collected from the Great Dismal Swamp National Wildlife Refuge (GDSNWR) and associated bottomland habitats were designated as "fisheri", animals collected farthest from the Swamp as "longirostris", and …
Community Structure Of The Macrobenthos In Back Bay, Virginia, Michael F. Lane
Community Structure Of The Macrobenthos In Back Bay, Virginia, Michael F. Lane
Biological Sciences Theses & Dissertations
A study of the subtidal macrobenthos in Back Bay, Virginia was conducted to examine community structure in relation to sedimentary and water quality characteristics. Samples were collected in August and November of 1987 and February and May of 1988 at ten stations.
Three site groups and three temporal groups were identified by cluster analyses of species abundance. Species composition between site groups was relatively homogeneous and eight species accounted for most of the variation between site groups. A comparison of plots of the biological and physical data in discriminant space suggested that variations in the biological data between site groups …

Threatened And Endanger Species Of Wetiands And Waterways In Iowa, Kansas, Missouri, And Nebraska, Ann Burruss
Threatened And Endanger Species Of Wetiands And Waterways In Iowa, Kansas, Missouri, And Nebraska, Ann Burruss
United States Environmental Protection Agency: Publications
Wetlands and waterways, including perennial and intermittent streams, creeks, and rivers, are habitats for many rare animal and plant species. Wetlands in many areas continue to decline in acreage and suffer adverse impacts from conversion and development. Waterways are also under pressure from channelization and leveeing.
This study has two major components. First, a series of databases was developed that includes animals and plant species that are wetland or waterway dependent and found in Iowa, Kansas, Missouri, or Nebraska. The databases allow ready access to detailed information on each species and probable locations within each state. The plant and animal …

Biodegradation Of Diflufenican Using Anaerobic Microbial Consortia, Velukumar T. Nanjagowder
Theses
In this thesis I examine the feasibility of using anaerobic microbial consortia from digested anaerobic sludge to degrade Diflufenican, a fluorinated herbicide released into the environment as a result of agricultural usage. The compound is manufactured by Rhone Poulenc and it is an active ingredient of agricultural herbicides. The anaerobic digested sludge served both as a source of microorganisms and as a growth medium. Initial studies were conducted by making a stock solution of 1 ppm concentration of Diflufenican in acetone, the optimal solubility of the compound as suggested in the material safety data sheet is 0.05 ppm in water. …

Farm Systems and Economics published reports
MIDAS is a bioeconomic model of mixed crop/livestock farms in Western Australia. It selects farm management strategies which maximise profit subject to resource, technical and environmental constraints using the linear programming technique. This document provides a thorough documentation of the version of MIDAS developed for the "eastern wheatbelt" region. If you are learning to use MIDAS with the MARG menu driven system, you need to read the MARG manual as well as this documentation.
From early in the life of MIDAS, we gave a high priority to making the data and assumptions readily accessible in documentation and in microcomputer spreadsheet …

Kinetics And Mechanisms Of Atrazine Adsorption And Desorption In Soils Under No-Till And Conventional Management, V. P. Evangelou, W. W. Witt, E. Portig, Mike Barrett
KWRRI Research Reports
Both soils (Maury silt loam and Sadler) exhibited three apparent mechanisms of atrazine adsorption. The first two mechanisms were very rapid (10 minutes) and were assigned to soil-clay surface adsorption reactions via hydrogen bonding. The quantity of atrazine involved in these two reactions for the 0.5 mg/1 solution atrazine varied, depending on the soil, from 67 μg/100 g clay to 219 μg/100 g clay. The reason there were two possible atrazine sinks in this range of atrazine adsorption was believed to be the presence of two types of reactive surfaces, the clay inorganic phase and the organic carbon phase. The …

Stable N-Chloraldimines And Other Chlorination Products Of Phenylalanine In Model Solutions And In A Wastewater, Barbara L. Conyers
Chemistry & Biochemistry Theses & Dissertations
Model solutions of the amino acid phenylalanine were chlorinated to seven Cl/N mole ratios. The by-products were characterized using gas chromatography, high performance liquid chromatography, GC/MS, infrared spectroscopy, and nuclear magnetic resonance spectroscopy. At the lower Cl/N ratios N-chlorophenylalanine and phenylacetaldehyde were identified as the main products while phenylacetonitrile and N-chlorophenylacetaldimine were the major products at Cl/N ratios of 2.0 and beyond. The concentration of phenylalanine in a municipal wastewater was determined. Using a radiotracer the chlorination products of phenylalanine in the wastewater at the 7 Cl/N ratios were identified as those seen in the model solutions. The distribution of …

The Aquatic Macroinvertebrates Of The White River National Wildlife Refuge, Steve W. Chordas Iii, George L. Harp
Arkansas Water Resources Center Technical Reports
The primary purpose of this study was to survey the diversity of the aquatic macroinvertebrates of the White River National Wildlife Refuge (WRNWR). Determining relative abundance and distributional and seasonal patterns were secondary objectives. No comprehensive investigations of the WRNWR aquatic macroinvertebrates had been conducted previously, and it was hypothesized that this relatively undisturbed area may serve as a refugium. Further, this study provides base line data by which management programs can be composed. Thirty sampling stations were established within the WRNWR. Samples were collected from north to south at a basic rate of five stations per month. Revisit collections …

Arkansas Water Resources Center Technical Reports
Studies were conducted to determine the environmental persistence of the rice pesticides triclopyr, 2,4-D, benomyl and quinclorac. Triclopyr half-lives ranged from <7 d to >100 d depending on depth within the soil profile and clay content. Triclopyr persistence increased as depth within the profile increased and clay content increased. The benomyl metabolite MBC was present at greater than 50% of the initial amount after 9 months in the field. In simulated carryover field studies quinclorac exhibited the greatest potential for injury to subsequent rotational crops. Cotton and soybean growth was reduced when planted at four weeks after quinclorac application. The adsorption of triclopyr …7>

Determination Of The Abient Toxicity Of The Tailwater Of Nimrod Lake, John T. Knight
Arkansas Water Resources Center Technical Reports
The objective of this research was to determine if ambient toxicity exists in the receiving stream below a reservoir in which water from the hypolimnion is released. The Ceriodaphnia 7-day test was utilized to determine if toxicity existed. This test is routinely used in the monitoring of municipal and industrial effluent. It has also been utilized in determining if ambient toxicity exists within receiving streams. Nimrod Lake is a flood control impoundment on the Fourche LaFave River in west central Arkansas. The literature suggest that during stratification the hypolimnetic release contains high levels of iron, manganese, ammonia and sulfide during …
