“…The high alkalinity and salinity coupled with low environmental stability in these lakes render them to characteristically sustain low floral and faunal diversity (Hecky & Kilham, 1973;Finlay et al, 1987;Gilabert, 2001;Harper et al, 2003;Grant, 2006;Oyoo-Okoth et al, 2011;Ong'ondo et al, 2013). Nevertheless, alkaline-saline environments are rich in terms of species biomass and productivity (Talling et al, 1973;Vareschi, 1982;Agasild & Nõges, 2007;Oduor & Schagerl, 2007;Okoth et al, 2009). The higher productivity, presumably reflects higher ambient temperatures, higher incident solar radiation throughout the year and unlimited access to inorganic carbon (Melack & Kilham, 1974;Grant, 2006).…”
