Qualitative And Quantitative Aquatic Algal Data Compilation To Determine Macrotrends - Iv, Richard L. Meyer
Qualitative And Quantitative Aquatic Algal Data Compilation To Determine Macrotrends - Iv, Richard L. Meyer
Technical Reports
A data base of the algae of Arkansas ecoregions has been estabblished by the use of a relational data base management system (dBase III plus). The system was chosen to be readily available for a variety of microcomputers using MS- and PC-DOS. The data base contains taxonomic fields from division through variety, synonymy, authors, initial description, date, and definitive descriptive source. The data are cross-referenced by ecoregion, Round's community and subcommunity designations. The data base contains greater than 1,500 taxonomic records in all divisions and classes of freshwater algae. The data are sortable by any of the included parameters. The …

Qualitative And Quantitative Aquatic Algal Data Compilation To Determine Macrotrends- Ii, Richard L. Meyer
Technical Reports
A database of the algae of Arkansas has been established by the use of a relational database management system (dBase III). The system was chosen to be readily available for microcomputers using MS and PC-DOS. The database contains taxonomic fields from division through variety, synonomy, authors, starting date and definitive descriptive source. The data is cross-referenced by ecoregion, community and subcommunity. The database contains nearly 1,500 taxonomic records in all division and classes of freshwater algae. These data are sortable by any of the included parameters. The data have been used to initiate the publication of the algal flora of …

Qualitative And Quantitative Aquatic Algal Data Compilation To Determine Macrotrends, Richard L. Meyer
Technical Reports
A data base of the algae of Arkansas has been initiated by the selection of a relational data base management system. The system was chosen to be readily available for microcomputers using MS- or PC-DOS. The initial parameters chosen for entry are associated with the classification of the organisms from Class to the Variety level with author and year of initiation. Further annotation includes identification source. Presently, the data base of 1,162 taxa includes 226 Cyanophyceae, 367 Chlorophyceae, 124 Euglenophyceae, 26 Xanthophyceae, 81 Chryso- phyceae, 279 Bacillariophyceae, 33 Pyrrhophyceae, 14 Cryptophyceae, and 5 Rhodophyceae. These taxa are sortable by any …
Evaluation Of Nitrogen And Phosphorus Enrichment Using In Situ Enclosure Bags With Temporal Indigenous Phytoplankton Populations, Richard L. Meyer, W. Reed Green
Evaluation Of Nitrogen And Phosphorus Enrichment Using In Situ Enclosure Bags With Temporal Indigenous Phytoplankton Populations, Richard L. Meyer, W. Reed Green
Technical Reports
An in situ experimental procedure and protocol was developed to evaluate nitrate and phosphate enrichment using isolated indigenous phytoplankton assemblages during different seasons. Results of the comparison of the parameters-temperature, pH, alkalinity, conductivity, and dissolved oxygen between the open water and enclosed systems indicated that there was no significant influence of the physicochemical factors on the isolated biological processes. Growth responses were measured by turbidity, biomass and chlorophyll-a, the most sensitive being chlorophyll-a. Additions of nitrate and phosphate were added in known concentrations and in different magnitudes of concentration based upon ambient conditions and ratio. During the fall, phosphorus influenced …

Appendices To An Aqueous Environmental Simulation Model For Mid-South Lakes And Reservoirs, Louis J. Thibodeaux
Technical Reports
The program simulates some of the major physical, chemical and biological processes occuring within the aqueous phase of lakes and reservoirs. The program was developed to study the eutrophic development of these water bodies.
