The diatom record: Reconstructing historically recent environmental change in the Knysna estuary
… and coastal ecosystems. This is the case of the Knysna Estuary, which is South Africa's highestrated estuary in terms of biodiversity and conservation importance. This study represents the first highresolution diatom record from the Knysna Estuary encompassing the last ∼680 years. Diatom analysis …

An analysis of factors controlling the distribution of zooplankton in the Knysna estuary, South Africa
The Knysna estuary system, on the south coast of South Africa, was sampled for zooplankton over period of one year. All species were recorded and an attempt was made at relating the distribution of populations to physical factors within the estuary. Over 50 species were identified. Pseudodiaptomus …

The role of water column and benthic communities in the spatial and temporal production and uptake of nutrients in controlling the trophic status of the Knysna River Estuary, South Africa
The Knysna Estuary is the largest estuarine ecosystem in the warm temperate coastal region of South Africa. The estuary remains oligotrophic (chlorophyll-a < 5 mg l-1) despite increases in anthropogenic input of nitrogen and phosphate associated with the rapidly increasing urbanization of its …
