Genetic Studies Of Cave And Spring Populations Of The Freshwater Amphipod Crustacean Gammarus Minus Say, Steven Wolf Hetrick
Genetic Studies Of Cave And Spring Populations Of The Freshwater Amphipod Crustacean Gammarus Minus Say, Steven Wolf Hetrick
Biological Sciences Theses & Dissertations
The amphipod Gammaru. minus has three morphotypes in its Appalachian range : (1) a spring form with well-developed eyes, (2) an intermediate cave form with slightly reduced eyes, and (3) an extreme cave form with greatly reduced eyes. This study compares the genetic structure of populations in two karst areas and analyzes the genetics of populations of the three morphotypes.
Genetic data were collected from populations in the Ward's Cove, Virginia and Greenbrier Valley, West Virginia karst areas using zone electrophoresis zymograms. One hundred percent of the Ward's Cove populations are polymorphic at both MDH-1 and PEP 1 loci …
Seasonal And Spatial Variation In Primary Productivity In Boulder Basin, Lake Mead, Clark County, Nevada, Isamu Aoki
Seasonal And Spatial Variation In Primary Productivity In Boulder Basin, Lake Mead, Clark County, Nevada, Isamu Aoki

The 14C light and dark bottle technique for measurement of primary production was utilized as a means of assessing the amount of inorganic carbon being converted Into organic form by the photosynthesis of phytoplankton populations In the Boulder Basin of Lake Mead.
Spatial and time series changes of productivity levels observed at eight sampling locations within Boulder Basin Indicate that the Influence of treated municipal arts' industrial effluent flowing into Les Vegas Bay is contributing high levels of available nutrients at Las Vegas Wash Inlet to cause productivity to approximate those levels associated with polluted waters.
Productivity levels at …

Dickey-Lincoln School Lakes Project
This report completes phase one of the study. It is intended to fill the need, recognized at the outset, for a broad framework within which subsequent more detailed study at the project level might take place. It is an overview of physical hydropower potential in the context of energy and water resources and demands, energy economics, and federal policy, organization, and practices pertaining to hydropower development and marketing.
