Baltimore Harbor And Channels Aquatic Benthos Investigations : Final Technical Report, Robert J. Diaz, Linda C. Schaffner, Robert J. Byrne, Robert A. Gammisch
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.
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.

Behavior And Ecological Interactions Of Larval Odonata, Clay L. Pierce, Philip H. Crowley, Dan M. Johnson
Clay L. Pierce
Enallagma aspersum and E. traviatum (Odonata: Coenagrionidae) are the most abundant larval odonates in Bays Mountain Park (Sullivan County, Tennessee, USA), although their spatial distributions are essentially nonoverlapping. E. traviatum coexists with insectivorous fish in a small lake, whereas E. aspersum is restricted to a small fishless pond nearby. Behavioral observations revealed that E. aspersum larvae were more active than E. traviatum, and tended to occupy more conspicuous positions. E. aspersum also engaged in more confrontations than E. traviatum, especially at higher density. In laboratorye xperimentsw ith juvenile bluegills( Lepomism acrochirusa) s predators,E . aspersum larvae were more vulnerable to …

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
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 …
Fluctuations And Relationships Of Selected Physiochemical Parameters In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson
Fluctuations And Relationships Of Selected Physiochemical Parameters In Dardanelle Reservoir, Arkansas, 1975-1982, John D. Rickett, Robert L. Watson
Journal of the Arkansas Academy of Science
Annual and seasonal fluctuations and relationships are described for discharge, turbidity, chloride, total hardness, conductivity and suspended solids over an eight-year period in Dardanelle Reservoir. The parameters fluctuated rather widely primarily in response to seasonal patterns of rainfall. Chloride and conductivity were related and generally fluctuated together as did turbidity and suspended solids. Hardness appeared to vary independently of the others prior to 1979 then varied more closely with chloride after March 1979. Inherent differences between the Illinois Bayou arm and the main Arkansas River sections complicated the precise identification of any overall impact of power plant operation. No significant …
The Green Movement: Implications For Animals, Ronnie Z. Hawkins
The Green Movement: Implications For Animals, Ronnie Z. Hawkins
Environment Collection
The Green movement, a newly emerging political movement that is both global in scope and firmly anchored to each local region at the grassroots level, is destined to be of great import to those concerned with the status of nonhuman animals in our society. Closely allied with deep ecology and bioregionalism, Green thinking embodies an alteration in our perception of the human organism: no longer seen as separate from and superior to all the other components of the ecosystem, our species is placed in context as one among many interdependent forms of life, with the attainment of a sustainable balance …

COMMUNITIES with Microtus tend to be structurally simple, usually grasslands or tundra, and to have no more than two species of Microtus and rarely more than six species of small mammals. Microtus often dominates both numerically and in total small mammal biomass, especially at higher latitudes. The small mammal community is most influenced by Microtus through its fluctuations in density, and thus also in biomass, by its relatively high level of diurnal activity, and by its year-round activity. Other species of small mammals may be adversely affected because Microtus usually is larger and behaviorally dominant and also because the mere …

Model To Predict Arkansas Gray Fox Fur Harvests, James H. Peck, Gary A. Heidt
Journal of the Arkansas Academy of Science
Linear regression analysis of total gray fox (Urocyon cinereoargenteus) fur harvests from 1954-1983 in Arkansas showed a high correlation with mean pelt values (r = 0.956). Single variable models using linear regression analyses of current season's pelt values (CSPV) and previous season's pelt values (PSPV) were designed to predict fur harvests. These models demonstrated high correlations for predicting harvests (r = 0.933 and r = 0.893 respectively). Regional analyses revealed a high correlation between mean pelt values and harvest for the Ozark Mountain region (r = 0.923), Ouachita Mountain region (r = 0.971 ), and Gulf Coastal Plain (r = …
