CAROTENOID COMPOSITION AS TAXONOMIC CHARACTER FOR MICROCYSTIS ISOLATES
Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: E.J. Smit G. H.J. Krüger J.N. EloffNineteen Microcystis aeruginosa isolates, a Microcystis incerta and a Synechococcus grown under constant conditions were analyzed for pigment composition. The carotenoid composition of Microcystis incerta and a Synechococcus isolate differed markedly from that of the other isolates. Although there were... -
Phytoplankton absorption and pigment adaptation of a red tide in the Benguela ecosystem
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: R Barlow --- , South Africa T Lamont --- , South AfricaPhytoplankton absorption and pigment characteristics of a red tide were investigated in coastal waters of the southern Benguela. Diagnostic indices indicated that dinoflagellates were the dominant phytoplankton group, with diatoms and small flagellates being of secondary importance. Very high biomass... -
Potential use of visible and near-infrared spectroscopy for pine species discrimination by examination of needles
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Silvana Nisgoski --- Department of Forest Engineering and Technology, Brazil Mayara E Carneiro --- Department of Forest Engineering and Technology, Brazil Elaine C Lengowski --- Department of Forest Engineering and Technology, Brazil Felipe Z Schardosin --- Department of Forest Engineering and Technology, Brazil Graciela I Bolzon de Muñiz --- Department of Forest Engineering and Technology, BrazilThe correct identification of pine species is necessary for proper application of wood in forest‑based industries, since the quality of each species’ wood depends on factors intrinsic to the material. The aim of this study was to evaluate the potential... -
Chemotaxonomic investigation of phytoplankton in the shelf ecosystem of the KwaZulu-Natal Bight, South Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: RG Barlow --- Bayworld Centre for Research and Education, South Africa T Lamont --- Branch: Oceans and Coasts, Department of Environmental Affairs, South Africa M-J Gibberd --- Marine Research Institute and Department of Oceanography, South Africa M van den Berg --- Branch: Oceans and Coasts, Department of Environmental Affairs, South Africa K Britz --- Branch: Oceans and Coasts, Department of Environmental Affairs, South AfricaPhytoplankton community structure was elucidated during summer and winter in the KwaZulu-Natal Bight using pigment and CHEMTAX analyses. The surface pattern in January 2010 indicated that diatoms, haptophytes and prasinophytes tended to be the most prominent groups inshore and in... -
Spatial variation of nutrients and primary productivity in the Rufiji Delta mangroves, Tanzania
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: A Minu --- , Tanzania J Routh --- , Sweden JF Machiwa --- , Tanzania S Pamba --- , TanzaniaDeterminations of spatial and temporal variations in organic matter and nutrient dynamics in water and sediments are crucial for understanding changes in aquatic bodies. In this study, we (i) determine the spatial dynamics of dissolved inorganic nutrients, during the transition...
