DIVMOM: Relationship between diversity and productivity of benthic diatoms along the salinity gradient in the Westerschelde, The Netherlands [Relatie tussen diversiteit en productiviteit van benthische diatomeeën langsheen de saliniteitsgradiënt van de Westerschelde] Citation Creach, V., Kromkamp J., Stal L. 2003: Relationship between diversity and productivity of benthic diatoms along the salinity gradient in the Westerschelde, The Netherlands. Netherlands Institute of Ecology; Centre for Estuarine and Marine Ecology, Netherlands. Metadata available at http://mda.nioo.knaw.nl/imis.php?module=dataset&dasid=1213. https://marineinfo.org/id/dataset/1213 Availability: Unrestricted The data are freely available to anybody and may be used for any purpose. Usage acknowledgement may be required Description The biodiversity of microphytobenthos and its spatial and temporal variability along the salinity gradient in the Westerschelde is described using a molecular approach in addition to the classical taxonomy. more A large number of species is isolated and a phylogenetic tree of the 18S rDNA of the diatoms is produced. This will be related to function i.e. primary production.
