The rise of potentially toxin producing cyanobacteria in Lake Naivasha, Great African Rift Valley, Kenya
(Elsevier, 2013-07)
Lake Naivasha, an important inland water ecosystem and a crucial freshwater resource in the Great African Rift Valley, has displayed clear signals of degradation in recent decades. We studied the phytoplankton composition ...
Haloleptolyngbya alcalis gen. et sp. nov., a new filamentous cyanobacterium from the soda lake Nakuru, Kenya
(Springer, 2012)
The food web of the saline-alkaline Lake
Nakuru is dominated by the cyanobacterium Arthrospira
fusiformis as the primary producer and a huge
population of Lesser Flamingos as direct consumers.
However, the dense blooms ...
Contribution of hot spring cyanobacteria to the mysterious deaths of Lesser Flamingos at Lake Bogoria, Kenya
(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 ...
Phylogenetic relationship and divergence among planktonic strains of Arthrospira (Oscillatoriales, Cyanobacteria) of African, Asian and American origin deduced by 16S–23S ITS and phycocyanin operon sequences
(2010-07)
Arthrospira comprises multicellular, cylindrical, usually screwlike coiled trichomes and is
cultivated commercially. In this study, 33 new strains of Arthrospira isolated from plankton
samples collected in Mexico, East ...
Genotypic diversity of Dictyosphaerium–morphospecies (Chlorellaceae, Trebouxiophyceae) in African inland waters, including the description of four new genera
(2012)
Trebouxiophytes of the Dictyosphaerium–morphotype from inland waters of Africa were studied using a polyphasic approach of SSU and ITS rDNA phylogeny, secondary structure of the ITS and observations made with a light ...
The Physico-chemical Conditions of Turkwel Gorge Reservoir, a New Man Made Lake in Northern Kenya
(1999)
Variations in some physical, chemical, and nutrient conditions were
investigated at Turkwel Gorge Reservoir and its inflowing river,
Suam between 1994 and 1995. Seasonal changes in inflow volume
had the greatest impact ...
Mass developments of the cyanobacteria Anabaenopsis and Cyanospira (Nostocales) in the soda lakes of Kenya: ecological and systematic implications
(2013)
The food web of the saline–alkaline lakes
of East Africa is characterised by a unique interaction
between the Lesser Flamingos as consumer birds
and the cyanobacterium Arthrospira fusiformis as the
primary producer. ...
Amino acid neurotoxins in feathers of the Lesser Flamingo, Phoeniconaias minor
(Elsevier, 2013-01)
The Lesser Flamingo (Phoeniconaias minor) is known to use cyanobacteria (primarily Arthrospira) as a major food source in the East African Rift Valley lakes. Periodically, mass mortalities have occurred, associated with ...
A cyano-anomaly? Cyanobacterial toxins as contributors to Lesser Flamingo mass deaths
(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 ...
Molecular detection of uncultured cyanobacteria and aminotransferase domains for cyanotoxin production in sediments of different Kenyan lakes
(Blackwell Publishing Ltd, 2009-04-15)
PCR-based denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA
gene fragments was used to identify the cyanobacterial phylotypes in sediments
and plankton of saline–alkaline and freshwater lakes of Kenya. ...
