Movement And Transformation Of Selected Organic Pollutants In Subsurface Environmet In Arkansas, Ali U. Shaikh

Arkansas Water Resources Center Technical Reports

Several subsurface soil and groundwater samples from eastern, southern and central Arkansas were analyzed for chlorinated organic compounds commonly used as pesticides and industrial chemicals. No significant amount of these compounds were found in these samples. The adsorption/partition characteristics of some of these compounds, such as dichlorophenols, aldrin and endrin, were determined in siltloam, sandyloam and clay soils collected from the above geographical locations. Results indicate that there is considerable difference in retention capability of different types of soils with respect to different pollutants. The partition coefficient of a particular compound in a certain type of soil can be related …

The Sunlight Effect On Trace Pollutants In Wastewater, Alan R. Sheu

Theses

In order to study the sunlight effect on the degradation rate of trace pollutants, ortho-cresol was selected to serve as a model compound in our studies. Solution of ortho-cresol alone, methylene blue alone, and the mixture of ortho-cresol and methylene blue were exposed to sunlight for more than four hours and aliquots analyzed with a spectrophotometer in order to follow the changes in absorption. Rate data were obtained for these three cases as a function of pH.

The results indicate that methylene blue does catalyze the degradation of ortho-cresol in the presence of sunlight with lower pH's affording higher reaction …

Indicators Of Microbial Activity In Biological Treatment Of Hazardous Wastes, Alexander Mclean Sherrin

Theses

Three methods were used to measure the activity of mixed liquor from the Livingston, N.J. municipal wastewater treatment plant on exposure to phenol. The three methods were, substrate removal rate (SRR), dissolved oxygen uptake rate (DOUR), and the dye reduction rate (DRR). Parameters from each test were compared for reproducibility and ease of determination. The SRR test gave the most reproducible results, while the DOUR test was the least reproducible. Although the reproducibility of the DRR test was close to that of the SRR test, the DRR was more time consuming and required a greater degree of expertise and training. …

Comparison Of Littoral And Limnetic Zooplankton Communities Of Lake Mead, Patrick Joseph Sollberger

Publications (WR)

Microfaunal communities were studied in littoral (inshore) and limnetic (offshore) areas of the lower basin in Lake Mead to compare species composition and abundance between the two zones. Planktonic forms (zooplankton) dominated inshore and offshore habitats and the occurrence of littoral species was low. Therefore, high similarity in zooplankton species composition was found among all sampling stations. This was perhaps due to two main factors: (i) the physical and chemical environment among the stations were very similar and (ii) the lack of aquatic vegetation in the littoral zone reduced the occurrence of littoral species.

Although species composition did not vary …

Disturbed Alpine Ecosystems: Seedling Establishment Of Early And Late Seral Dominant Species, Jeanne C. Chambers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the effects of seedbed and seedling environment on establishment of early and late seral dominant alpine species. Species studied included late seral dominant forbs (Geum rossii, Artemisia scopulorum, and Polemonium viscosum), early seral dominant forbs (Potentilla diversifolia and Sibbaldia procumbens), a late seral dominant grass (Festuca idahoensis), and early seral dominant grasses (Calamagrostis purpurascens and Deschampsia cespitosa). Germination responses of each species to wet vs. dry cold stratification and light vs. dark conditions were investigated. No statistical differences were observed in the seed germination of early and late …

Importance Of Attractant Qualities For Improving A New Coyote Delivery System, Steven M. Ebbert, Daniel B. Fagre

Great Plains Wildlife Damage Control Workshop Proceedings

Changes in effectiveness and nontarget species selectivity of a new system for delivering ingestible substances to coyotes (Canis latrans) were examined by systematically varying odor type and quantity used to attract coyotes to the device. The new delivery system's efficacy was comparable to the M-44 in our tests in south Texas. A synthetic lure improved the effectiveness of the delivery system when applied in amounts of 0.10 cc or 0.50 cc. Varying odor type did not increase the incidence of desirable coyote behavior, such as biting, but did increase rates of visitation.

Control Of Ecosystem Processes By Prairie Dogs And Other Grassland Herbivores, James K. Detling, April D. Whicker

Great Plains Wildlife Damage Control Workshop Proceedings

Black-tailed prairie dogs in the mixed-grass prairie at Wind Cave National Park, South Dakota, create habitat patches characterized by altered species composition, lower standing crops of plants, but higher forage quality. Native wildlife species such as bison, pronghorn, and elk preferentially feed on these prairie dog colonies and likely derive nutritional benefits from doing so.

Overwater Nesting By Ducks: A Review And Management Implications, Stephen H. Bouffard, David E. Sharp, Carol C. Evans

Great Plains Wildlife Damage Control Workshop Proceedings

Nest success of overwater duck nests is generally higher than nests in upland sites. A review of the literature indicated that the major factors limiting success of overwater nests were fluctuating water levels, nest parasitism, predation, and human disturbance. Regional patterns of the occurrence of these factors could not be discerned. General management guidelines for improved recruitment and reduced nesting female mortality are suggested.

A Statistical Model Of Expansion In A Colony Of Black-Tailed Prairie Dogs, R. P. Cincotta, D. W. Uresk, R. M. Hansen

Great Plains Wildlife Damage Control Workshop Proceedings

To predict prairie dog establishment in areas adjacent to a colony we sampled: (1) VISIBILITY through the vegetation using a target, (2) POPULATION DENSITY at the colony edge, (3) DISTANCE from the edge to the potential site of settlement, and (4) % FORB COVER. Step-wise regression analysis indicated that establishment of prairie dogs in adjacent prairie was most likely to occur when an area was near a densely populated colony edge with high visibility through the vegetation.
