Differences between them are promoted by three ecological drivers: salinity, turbidity and hydroperiod. Community structure and phenology of the two most common types, saline lakes and claypans, are known but similar ecologies are lacking for the third most common wetland, the treed swamps. These are of six subtypes distinguished by dominant tree species, geomorphology and hydroperiod, all with similar community structure and phenology, but with differing invertebrate diversities. Summed diversity is not as high as in local creek pools, the shorter hydroperiods and simpler geomorphology of the treed swamps being restrictive so that there is almost no replacement of species during the early dominance of branchiopods and later of insects. Such treed swamps are uncommon in the semi-arid zone, but much more speciose treed swamps are known under similar and seasonally dry Mediterranean climates of the Western Australian Wheatbelt where hydroperiods are more stable.

In Australia, the most important driver affecting biodiversity is salinity that imposes an inverse linear relationship. However, in detailed studies across a wide salinity spectrum, the relationship is scale dependent. This is mediated in part by the range of salinity tolerated becoming broader as the maximum tolerated salinity increases. Other factors of importance sometimes include hydrology, habitat heterogeneity, season, pH and oxygen, but these are usually not easy to quantify. Even rarer is the influence of colonisation by marine organisms, which is applicable only at some sites near the coastline and the influence of ionic proportions on the presence of some species and, hence, diversity. The contribution of predation or competition on diversity, reported in some overseas salinas, is suspected but yet to be proved in Australia. The crustacean component in saline lakes is more influenced by these drive...

A second species of Australimnadia is described from Onslow, Western Australia; it differs in having unique egg morphology and is distinct in many morphological characters, including those of the telson and cercopod, but also of the thoracopods. Its validity is confirmed by molecular differences between the two species in COI and EF1α. A third species from southwestern Western Australia is separated morphologically by unique spination of the telson and setation of the cercopod, and by its egg morphology.

It is characterized by some peculiar features, such as presence of well developed rostrum, small reduced eye, and large hooked spine on the apical end of upper two-segmented antennal branch, which distinguish it from other known species of the genus. The new species is probably closely related to the Australian D. unguiculatum and may be considered as the additional member of the Australian endemic fauna. The ecological signifi cance of morphological features of the species is discussed. Manuscript received 29 March 2010, accepted for publication 19 July 2011.

Lake Nargal near Narooma, Bondi Lake near Bega, and a small lagoon near Pambula have little in common limnologically with coastal dune lakes of northern NSW and southern Queensland. They differ in mode of origin, are less dominated by NaCl, are less acidic, are more speciose, have few characteristic dune-lake indicator species, and moreover contain certain southern species. However, a re-examination of data for Lakes Windermere and McKenzie further north at Jervis Bay suggest that these are classic dune-contact lakes rather similar to those in northern NSW. Differences and similarities are largely influenced by the extent and therefore the hydrological influence of the contextural coastal sand mass and by biogeography.
