Type: UG-1239

Category: Algae

Taxonomical identification: Scenedesmus sp.

First publication: Gelorini, V., Verbeken, A., van Geel, B., Cocqyt, C. and Vershuren, D. (2011) Modern non-pollen palynomorphs from East African lake sediments. Review of Palaeobotany and Palynology 164, 143–173

Other publication/s: Cronberg, G. (1986) Blue-green algae, green algae and chrysophyceae in sediments. In: Berglund, B.E. (ed.), Handbook of Holocene Palaeoecology and Palaeohydrology. John Wiley and sons, Chichester, pp. 507–526

Description: Colonies linear, hyaline, 26 (30) × 17 μm, with four ellipsoid to oblong cells, arranged subparallel to each other, broadly rounded or slightly truncate, and with a smooth surface. Cells 5–8 × 17–22 μm.

(Sub-) Fossil occurence: The joint occurrence of Scenedesmus and Pediastrum species in small water bodies (wells, ditches, watering holes, etc.) and as fossils in lake deposits is indicative of eutrophication caused by human activities and therefore has occasionally been used to infer past organic pollution (Cronberg, 1986).

Co-occurence: No information

Modern occurence: Scenedesmus species typically occur in freshwater ponds, lakes and/or slow-moving rivers, most abundantly in slightly eutrophic waters.

Palaeoenvironmental indication: Organic pollution
