Effects Of Disruptive Grazing By The Mud Snail Ilyanassa Obsoleta On Mudflat Nematode Populations, David Ludwig
Effects Of Disruptive Grazing By The Mud Snail Ilyanassa Obsoleta On Mudflat Nematode Populations, David Ludwig
Dissertations, Theses, and Masters Projects
Population densities of the mud snail Ilyanassa obsoleta were manipulated in caging experiments on a salt marsh mudflat and in laboratory microcosms. Mud snails outcompete nematodes for food resources, but may increase resources available to deposit feeding groups. Mud snails reduce annelid (polychaete and oligochaete) populations by substrate disruption. Reduced annelid densities provide the nematode community with some release from predation and competition. In mudflat sediments, the nematode community responds to both primary (predation) and secondary (envirorm1ental release, food competition) interactions. Multiple levels of interactive coupling should be considered in any systems level investigation in this habitat.

Adenine Nucleotide Levels And Adenylate Energy Charge In Zostera Marina (Eelgrass): Determination And Application, Damon A. Delistraty
Adenine Nucleotide Levels And Adenylate Energy Charge In Zostera Marina (Eelgrass): Determination And Application, Damon A. Delistraty
Dissertations, Theses, and Masters Projects
An analytical technique was developed to measure adenine nucleotide levels (ATP, ADP, AMP) and adenylate energy charge (EC) in Zostera marina (eelgrass), a submerged marine angiosperm. A tissue comparison and seasonal survey provide baseline information on natural adenylate variability. The methodology developed can be suitably adapted to other macrophyte species as well. Plants were frozen, lyophilized, scraped free of epiphytes, and homogenized. Adenylates were extracted with boiling 1 mM EDTA + 5% (w/v) PVPP (pH 7.6), and assayed by enzymic conversion of AMP and ADP to ATP, followed by quantitative analysis of ATP via the firefly bioluminescent reaction. ATP, ADP, …

A Study Of Nutritional Requirements Of The Larvae Of The American Oyster (Crassostrea Virginica), Fu-Lin E. Chu
A Study Of Nutritional Requirements Of The Larvae Of The American Oyster (Crassostrea Virginica), Fu-Lin E. Chu
Dissertations, Theses, and Masters Projects
The purpose of this study is to obtain information for the formulation of artificial diets for larvae of the American oyster (Crassostrea virginica) and to test procedures related to presenting these diets to the oyster larvae. In order to determine the nutrient components usually provided in larval diets, biochemical analyses of lipids and fatty acids, proteins and amino acids and polysaccharide carbohydrates were performed on five algae species used as a food source for oyster larvae. These algae are Chlorella sp., Pyramimonas virginica, Pseudoisochrysis paradoxa, Pavlova (Monochrysis) lutheri and Isochrysis galbana. The biochemical analyses indicate that the nutritional value of …
