“…Their application in monitoring change, and their relationships with major environmental variables in salt-lake environments, is well documented from locations world wide. Applications include using diatoms to predict drought periodicity, past climate conditions, salinity changes and water-body nutrient status (Gell and Gasse 1990;Servant-Vildary and Roux 1990;Gasse et al 1997;Gell 1997;Gaiser et al 1998;Reed 1998;Fritz et al 1999;Fritz 2000, 2002;Gasse 2002).…”

Distribution of modern diatom assemblages among small playas

et al. 2008

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 with known adaptations to saline conditions and fluctuations in salinity in NaCl dominated waters. Data were analysed by ordination (MDS and PCA), hierarchical clustering (CLUSTER), permutation-based hypothesis testing (ANOSIM) and comparative tests on similarity matrices (RELATE). Water depth accounted for the majority of variation in the environmental data. REALTE comparisons of environmental and taxa data did not produce a significant correlation value. We propose that the poor concurrence of the datasets was influenced by the wide ecological tolerances of the taxa recorded, some crucial unmeasured environmental variable/s, possible geographical regionalisation and/or unsampled taxa variability owing to the stochastic nature of the wetlands. Broad patterns of distribution were related to hydroperiod and some taxa groups were loosely associated with environmental groups consistent with established ecological tolerances for the taxa.
