The trophic position of planktonic ciliate populations in the food webs of some East African lakes
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: AndrewW Yasindi WilliamD TaylorThe trophic role of planktonic ciliates was investigated in the food webs of 17 East African lakes of different salinity and trophy. Experiments with 1μm latex beads showed that Cyclidium, Halteria, Dysteria, Aspidisca and Vorticella are bacterivores. Examination of food... -
Feeding of the tintinnid ciliate Favella taraikaensis on the toxic dinoflagellate Alexandrium tamarense and the fate of prey toxins
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: T Kamiyama T Suzuki Y OkumuraTo establish the fate of paralytic shellfish poisoning (PSP) toxins in planktonic foodwebs, feeding activities of the planktonic ciliate Favella taraikaensis on the PSP-producing alga Alexandrium tamarense were examined in laboratory experiments and the toxin content in the ciliates was... -
The community composition and biomass of pelagic ciliated protozoa in East African lakes
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: AndrewW Yasindi WilliamD Taylor DenisH LynnThe community composition and biomass of planktonic ciliates were studied in 17 tropical East African lakes varying from freshwater to saline, and from oligotrophic to eutrophic. The conductivity of the lakes varied from 207μS cm−1 to 70 000μS cm−1. Chlorophyll...
