Analysis of the cyanotoxins anatoxin-a and microcystins in Lesser Flamingo feathers.
Metcalf, J.S.; Morrison, L.F.; Krienitz, L.; Ballot, A.; Krause, E.; Kotut, Kiplagat; Pütz, S.; Wiegand, C.; Pflugmacher, S.; Codd, G.A. (Taylor & Francis, 2006)Feathers from carcasses of the Lesser Flamingo (Phoeniconaias minor), which had died after ingesting cyanobacterial toxins (cyanotoxins) contained between 0.02 and 30.0 µg microcystin-LR equivalents per gram of feather ... -
Contribution of hot spring cyanobacteria to the mysterious deaths of Lesser Flamingos at Lake Bogoria, Kenya
Krienitz, L.; Ballot, A.; Kotut, Kiplagat; Wiegand, C.; Pütz, S.; Metcalf, J.S.; Codd, G.A.; Pflugmacher, S. (Elsevier, 2003-03-01)Cyanobacterial mats at hot springs on the shore of the alkaline Lake Bogoria, Kenya, were investigated regarding species community and cyanobacterial toxin content. The hepatotoxins microcystin-LR, -RR, -LF and -YR, and ... -
Contribution of tixic cynobacteria to massive deaths of lesser flamingoes at saline-alkaline lakes of Kenya
Krienitz, L.; Ballot, A.; Casper, P.; Codd, G.A.; Kotut, Kiplagat; Metcalf, J.S.; Morrison, L.F.; Pflugmacher, S.; Wiegand, C. (2003) -
A cyano-anomaly? Cyanobacterial toxins as contributors to Lesser Flamingo mass deaths
Codd, G.A.; Metcalf, J.S.; Morrison, L.F.; Krienitz, L.; Ballot, A.; Pflugmacher, S.; Wiegand, C.; Kotut, Kiplagat (2003-10)In the present study, significative HAB’S bloom was confirmed in Matanchén Bay during Febrary 2003. The Raphidophice Fibrocapsa cf. japonica, Toriumi et Takano 1973 (=Chatonella japonica) has dominated (97%) red ... -
Cyanobacteria and cyanobacterial toxins in the alkaline crater lakes Sonachi and Simbi, Kenya
Ballot, A.; Krienitz, L.; Kotut, Kiplagat; Wiegand, C.; Pflugmacher, S. (Elsevier, 2005-01)The phytoplankton communities and the production of cyanobacterial toxins were investigated in two alkaline Kenyan crater lakes, Lake Sonachi and Lake Simbi. Lake Sonachi was mainly dominated by the cyanobacterium Arthrospira ... -
Cyanotoxin-producing bloom of Anabaena flos-aquae, Anabaena discoidea and Microcystis aeruginosa (Cyanobacteria) in Nyanza Gulf of Lake Victoria, Kenya
Krienitz, L.; Ballot, A.; Wiegand, C.; Kotut, Kiplagat; Codd, G.A.; Pflugmacher, S. (2002)A bloom of Anabaena flos-aquae, Anabaena discoidea and Microcystis aeruginosa, was characterized in Nyanza Gulf of Lake Victoria, near Kisumu, Kenya. According to classical literature data, A. discoidea was considered to ...
