Numerous analyses of the major ions in surface waters of South Australia, south-western Western Australia, and northern Australia are presented and discussed. In South Australia three regions were investigated: the Yorke Peninsula, the Snowtown area, and the extreme south-east including the Coorong. In all three areas salinities were high, except for Lake Alexandrina and Lake Albert at the mouth of the River Murray, and sodium and chloride were the dominant ions. In rivers and standing waters in the south-west of Western Australia sodium and chloride were likewise the dominant ions. Almost all standing waters sampled in this region were saline and salinity was also high in some rivers investigated; there are, nevertheless, freshwater lakes and rivers of low salinity in this region. In running and standing waters of northern Australia, salinities were low and there was no consistent pattern of ionic dominance.

Based on nearly 2000 available records, the broadscale geographical distribution of the native earthworm fauna of Australia was mapped. Native earthworms were recorded from south-eastern, eastern and northern Australia within 400 km of the coast. Isolated faunas were present in Tasmania and south-west Western Australia, and apparently isolated faunas occurred in the Adelaide area/Fleurieu Peninsula of South Australia and the ranges of central Australia. All but 30 locality records occurred where annual rainfall averaged or exceeded 400 mm; 16 of these records were instances of moisture-gaining sites (moist caves, waterholes, banks of large rivers, edge of granite domes). A collecting strategy to both fill in gaps in the distribution map and discover additional anomalous occurrences (with respect to the 400 mm isohyet) is outlined.

Previous movement studies on the southern rock lobster (Jasus edwardsii) have all involved releasing tagged animals at the point of capture. In 2007, 5298 lobsters, in total, were tagged and translocated from an offshore site (>100-m depth) to two inshore sites (<20-m depth) in South Australia. After a period of 735 days, 510 (9.6%) had been recaptured. The majority of translocated lobsters were located within close proximity to the release points, with 306 (60%) having moved <5km. Of the remainder, 133 (26%) were recaptured within 5–10km, with a further 71 (14%) individuals having moved >10km. Movement patterns were highly directional in nature, with individuals consistently travelling in a south-west bearing, regardless of distance moved. In almost all cases, movement was from inshore to offshore sites, with female lobsters travelling significantly further (mean 5.66km ±6.41s.d.) than males (mean 5.02km ±9.66s.d.). The results are consistent with previous large-scale tagging studies of J. edwardsii, which indicated high residency levels but with occasional directed movement by some individuals.

The sex form of each species in the flora of the south-west of Western Australia was determined, and the proportions of the different forms compared with data available for South Australia. Although the western flora has been substantially isolated since at least the mid Tertiary, no significant difference in the proportion of hermaphrodite species from that of South Australia was found. A re-analysis of the sex forms of the flora of the British Isles was also made, and it was found that this flora has a higher proportion of non-hermaphrodite species than has either Western Australia or South Australia. The possible evolutionary significance of these observations is discussed.

Pitjantjatjara is a dialect of the Western Desert Language (WDL) of central Australia (Douglas 1958). The Western Desert Language is a member of the south-west Pama-Nyungan group. Together with Warnman, it forms the Wati sub-group. It is spoken by 4000–5000 people, and covers the widest geographical area of any language in Australia, stretching from Woomera in central northern South Australia, as far west as Kalgoorlie and Meekatharra and north to Balgo Hills, in Western Australia. The main dialects, which differ most in regards the lexicon but also to some extent in grammar and phonology, include Pitjantjatjara, Yankunytjatjara, Ngaanyatjarra, Ngaatjatjarra, Southern Luritja, Pintupi-Luritja, Kukatja, Gugarda, Ngalia, Wangkatja, Wangkatha, Manyjilyjarra, Kartutjarra and Yurlparija. It is perhaps more accurately conceived of as a dialect chain, whereby a dialect such as Pitjantjatjara is mutually intelligible with its neighbours Ngaanyatjatjarra and Yankunytjatjara, but not with dialects more distant than these, such as Kukatja and Manyjilyjarra.

Although medusae of the scyphozoan Phyllorhiza punctata are abundant in the Swan-Canning estuary during summer, they are absent when surface waters are dominated by low-salinity runoff water following winter rains. In the laboratory, scyphistomae of P. punctata are shown to survive in conditions of temperature and salinity that occur in the estuary during winter in waters deeper than 5 m. It is postulated that areas of deep water provide a winter refuge for scyphistomae and that asexual production of both ciliary buds and ephyrae enables rapid growth of the P. punctata population in the spring of each year.

The geographical distribution and host relations of the five species of Trombella parasitising adult 'short- horned' grasshoppers in Australia are described on the basis of data derived from a screening of tens of thousands of grasshoppers in the Australian National Insection Collection and covering 133 localities and 335 individual hosts in 79 species. Most of the data refer to T. cucumifera Southcott, which occupies a large region across northern Australia, where it is sympatric with T. fusiformis Southcott, and extending south into New South Wales. T. rugosa Southcott and T. sternutor Southcott are sympatric in the south- west of Western Australia. T. calabyi Southcott is represented by a single specimen from the arid east-Pilbara area of Western Australia. Host species are listed for each species of mite. Eumastacidae and Tetrigidae appear not to be attacked, but within the other two Australian families (Pyrgomorphidae and Acrididae) representatives of all of the five Australian subfamilies serve as hosts. For T. cucumifera, attack rates of 20-67% of the captured samples of some species of those families were recorded at some localities. There is a suggestion that the most abundant of the geophilous grasshoppers present at any locality may be favoured and that the species of Trombella do not differ in their utilisation of the grasshopper species accessible to them. There is no evidence of sex bias in host selection. The most common number of mites found on a single host individual is one in the three mite species with adequate data; it ranges up to 11, but numbers above five are rare. All species are attached almost exclusively to the membrane between prosternum and mesosternum of the host, or the membranous insertion of coxa 111.

The concentrations of major ions (Na+, K+, Ca2+, Mg2+, Cl-, SO42- and HCO3- + CO32-) and minor ions (NO2, NO3-, NH4 and PO43-) were determined in 10 saline and mostly ephemeral lakes on the Yorke Peninsula, S.A., over a range of salinity (27-250 g/l). The major ion dominances were similar to those of saline lakes elsewhere in southern Australia: Na+> Mg2+ > Ca2+ > K+ : Cl- > SO42- > HCO3- + CO32-. Concentration ranges of minor ions were wide; individual concentrations of ions were not correlated with salinity, but in the least-saline lakes (salinity < 150 g/l) phosphorus appears to be the most likely limiting plant nutrient, whereas in the more saline lakes (>150 g/l) nitrogen appears to be so.

The numbat (Myrmecobius fasciatus ) was formerly widespread across most of southern Western Australia, South Australia and western New South Wales. It delined in the early 1900's, possibly due to foxes, cats, or an epizootic. Protection through control of foxes and cats, and translocation, has resulted in several populations being re-established at sites of historical distribution.

Water striders or pond skaters belonging to the subfamily Gerrinae are common inhabitants of various types of fresh water throughout eastern and northern Australia. The present paper deals with the 13 species (in 5 genera) known from Australia. Redescriptions or descriptive notes, illustrations, and keys to adults and nymphs of all species are provided and their distributions recorded and mapped.Tenagogerris pallidusand T. femoratus (both from Northern Territory and Western Australia), Tenagogonus australiensis (Queensland), Limnometra ciliodes (Queensland, Papua New Guinea and Irian Jaya), and Limnogonus fossarum gilguy (Northern Territory, Queensland, South Australia, Western Australia, Indo-Malayan Archipelago, and West Pacific to Samoa and Tonga) are described as new. Limnometra poliakanthinaNieser & Chen is synonymised with L. cursitans (Fabricius) and Hydrometra australis Skuse (= Limnometra skusei Torre-Bueno) with Limnogonus luctuosus (Montrouzier). The evolution and zoogeography of Australian water striders are discussed. Finally, we discuss the ecology of the gerrine water striders of Australia in relation to our present knowledge about habitats, phenology, wing polymorphism, and association between species.

Surface waters of the Lake Pedder area are characterized by low salinity, low pH, high colour, and a relative major-ion composition near that of seawater. Factors determining this composition are predominance of inert rocks, a covering of sedgeland peat isolating waters from rock contact, and a high rainfall brought by prevailing oceanic winds. Frequency and intensity of rainfall appear to determine the pattern of chemical variation. Salinity, bicarbonate, and pH may change rapidly during periods of high rainfall. Humic acids are important chemical constituents of the waters, and probably determine the type of biotic community which inhabits them.
