“…Pans, closed depressions, occur in the Pampas and Patagonia of Argentina; east Tierra del Fuego; the High Plains of the United States; the interior of southern Africa; east Mozambique; and extensive tracts of Australia, West Siberia, and Manchuria (Goudie & Wells 1995) (Figure 1). Some pan fields consist of tens of thousands of basinsfor example, those of Western Australia (Boggs et al 2006). They are a feature of low-angle surfaces on which the development of integrated drainage is limited.…”

Recently, the importance of wind erosion has been reevaluated. Many low-angle surfaces, developed on susceptible materials, possess closed depressions (pans), and these often have a distinctive morphology and lunette dunes on their lee sides. It has also become apparent that in drylands there are extensive areas of stone pavements, some of which have been molded by deflation; however, it is now recognized that other horizontal sorting processes have played a role, especially movement of fines by overland flow. Vertical sorting associated with wetting and drying, salt heave, bioturbation, frost action, and dust accretion have also played a role. In hyperarid areas, especially with unidirectional winds, bedrock outcrops and old lake beds have been molded to give aerodynamic forms, called yardangs. The study of dust storms by analysis of climatological data and remote sensing has revealed the importance of deflation, especially in hyperarid areas with centripetal drainage. Deflation hot spots, such as the Bodélé Depression, have been identified. Analysis of ice and ocean cores and loess deposits has indicated that wind activity was greater during glacial phases than now. There is, however, great variability in the importance of wind at the present day, depending on the wind velocity characteristics of different deserts. 97 Click here for quick links to Annual Reviews content online, including: • Other articles in this volume • Top cited articles • Top downloaded articles • Our comprehensive search Further ANNUAL REVIEWS Pan: a closed desert topographic depression developed on low-angle surfaces as a result of processes such as deflation and salt weathering Lunette: a crescent-shaped accumulation of eolian sediment that is deflated from a pan and then deposited as a positive topographic feature on its lee side Deflation: the process by which the wind removes fine material from a surface www.annualreviews.org • Wind Erosion in Deserts Indexes Cumulative Index of Contributing Authors, Volumes 26-36 p p p p p p p p p p p p p p p p p p p p p p p p649 Cumulative Index of Chapter Titles, Volumes 26-36 p p p p p p p p p p p p p p p p p p p p p p p p p p p p p p p p p653 Errata An online log of corrections to Annual Review of Earth and Planetary Sciences articles may be found at http://earth.annualreviews.org viii Contents

“…The role of groundwater as a factor in pan formation and development has been most closely considered through studies in Australia (e.g. Bowler, 1986;Torgersen et al, 1986;Jacobson, Ferguson and Evans, 1994;Dutkiewicz and von der Borch, 1995;Boggs et al, 2006;Cupper, 2006;Harrington, Herczeg and La Salle, 2008), the Americas (e.g. Osterkamp and Wood, 1987;Paine, 1994;Rosen, 1994;Risacher, Alonso and Salazar, 2003;French et al, 2006;Risacher and Fritz, 2009;Scuderi, Laudadio and Fawcett, 2010) and in the Kalahari (e.g.…”

“…This rainfall gradient generates variability in playa hydroperiod and filling frequency. The origin and geomorphology of the system has been discussed in detail elsewhere (Killigrew and Gilkes 1974;Beard 1999Beard , 2000Boggs et al 2006). Six small playas (>3 km 2 ), comprising three pairs of adjacent lakes, were chosen for detailed investigation, and labelled Mongers A (MONA), Mongers B (MONB), Kadji A (KA), Kadji B (KB), Morawa A (MA) and Morawa B (MB).…”

“…Small 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).…”

Distribution of modern diatom assemblages among small playas

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.
