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 ...
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 ...
Hidden diversity of eukaryotic plankton in the soda lake Nakuru, Kenya, during a phase of low salinity revealed by a SSU rRNA gene clone library
(Springer, 2013)
A SSU rRNA gene clone library was
constructed to establish the diversity of eukaryotic
plankton in the African soda lake Nakuru during a
phase of low salinity (9.7 ppt = hyposaline). Normally,
the lake is mesosaline ...
Hydrochemical Characteristics, Plant Nutrients and Metals in Household Greywater and Soils in Homa Bay Town
(2012)
Greywater recycling has been identified as an efficient method to conserve water. The purpose of this study was to investigate some selected hydrochemical characteristics, plant nutrients and metal content of greywater and ...
Fluctuating algal food populations and the occurrence of lesser flamingos (Phoeniconaias minor) in three Kenyan rift valley lakes
(2010-06)
The last two decades have witnessed increasing episodes
of lesser flamingo die-offs in East Africa. Based
on data on phytoplankton composition, biomass, and
flamingo population density in three alkaline-saline
lakes ...
Physico-Chemical and Microbial Quality of Greywater from Various Households in Homa Bay Town
(2011)
In recent years concerns over dwindling reserves of ground water and overloaded or costly sewage treatment plants has generated much interest in the reuse or recycling of greywater. Re-use of greywater offers several ...
Molecular diversity of plankton in a tropical crater lake switching from hyposaline to subsaline conditions: Lake Oloidien, Kenya
(Springer, 2016-09)
Salinity in the climate sensitive tropical
endorheic crater lake Oloidien (Great African Rift
Valley, Kenya) decreased from hyposaline to subsaline
conditions during the period 2010–2015. The
change in salinity was ...
