Zooplankton Community Abundance And Diversity In Dardanelle Reservoir, Arkansas, 1981-1990, John D. Rickett, Robert L. Watson
Zooplankton Community Abundance And Diversity In Dardanelle Reservoir, Arkansas, 1981-1990, John D. Rickett, Robert L. Watson
Journal of the Arkansas Academy of Science
Zooplankton samples were collected quarterly from five stations representing the discharge bay and four "control" or "dispersing impact" stations. Rotifers dominated all samples numerically and by the number of taxa. All major groups (Rotifera, Cladocera, Copepoda, and Protozoa) exhibited greatest abundances during the summer. Quarterly variations in abundance and number of taxa were documented. Except for an increase in taxonomic analysis detail between 1981 and 1984 resulting in several more taxa added to the list, no long-term increases, declines or repeating cycles were apparent. Margalef's Richness Index reflected this change and showed a long-term increase with evidence of a 5- …

Groundwater Investigations In The Jerramungup Shire, S B. Martin
Groundwater Investigations In The Jerramungup Shire, S B. Martin
Resource management technical reports
Drilling was carried out with a dry rotary auger rig, with a depth limit of 31 m for the first 28 piezometers and 40 m thereafter. Farmers assisted in the site selection and construction of the piezometers in most cases and will in the future be responsible for monitoring their piezometer(s) regularly. The average depth to bedrock was 18 m and the average dept to groundwater was 9 m, with an average salinity level of 3600 mS/m. The average total salt storage was approximately 2800 tonnes per hectare.

Land Reclamation In The North Stirling Land Conservation District, M F. Lewis, National Soil Conservation Program (Australia)
Resource management technical reports
Investigations were carried out to determine the interaction between the lakes and groundwater systems, the influence of bedrock structures on groundwater flow, and the regional flow characteristics in the basin. The hydrological investigations showed that water does flow from lakes to the groundwater system. However, the benefits from draining land have to be compared with the benefits of not adding water to the lakes. A basin water balance showed that most of the excess water resulting from reduced epotranspiration since clearing remains in the basin as increased groundwater storage. Only relatively small quantities of the extra water leave the basin …

Molecular mechanisms that drive metabolic acclimation to environmental shifts have been poorly characterized in phytoplankton. In this laboratory study. the response of light- and N-limited Skeletonema costatum cells to an increase in light and NO3 availability was examined. C assimilation was depressed relative to N assimilation early in enrichment, and the photosynthetic quotient (O2: CO2) increased, consistent with the shunting of reducing equivalents from CO2 fixation to NO3- reduction. The concomitant increase in dark respiration was consistent with the increased energetic demand associated with macromolecular synthesis. The accelerations of N-specific rates of …
