Diatom diversity of six small playa lakes within the Yarra Yarra drainage system, Western Australia, and the environmental variables likely to influence their distribution was investigated. Thirty-one pennate diatom taxa were identified. Taxa consisted of facultative planktonic and periphytic, circumneutral to alkaliphilous or pH-indifferent forms...

... playas (>10 ha) constitute numerically more than half of the salt lakes of the Yarra Yarra drainage system in the Yarra Yarra catchment area of Western Australia ( Fig. 1) (Boggs et al. 2006). They are ephemeral and, while ionically similar, exhibit a range of hydrochemical environments through variable hydroperiods and filling frequencies brought about by rainfall and catchment variability (Boggs et al. 2007a). As well as being spatially variable, individual playas can be highly temporally irregular in ...

... Yarra Yarra drainage system comprises a chain of more than 4500 playas located in the northern wheatbelt of Western Australia, ∼300 km north-east of Perth (Fig. 1). Spanning several rainfall isohyets in the semi-arid zone of Western Australia, the average annual rainfall is 450 mm in the south-west of the catchment, decreasing to 200 mm in the north-east. This rainfall gradient generates variability in playa hydroperiod and filling frequency. The origin and geomorphology of the system has been ...

... Boggs et al. 2007b suggested that lake beds in the Yarra Yarra region might contain microbial communities with diversity that is unique to the region. However, in a subsequent study, no unique diatom species were found in crusts or surface waters (Boggs et al. 2008). Aquatic invertebrate monitoring in the southern part of the Yarra Yarra basin also found most species to be ubiquitous (WRM 2008). ...
