Chemistry of salt lakes and other water of the sub-humid regions of Tasmania

Analyses are presented of major chemical features of pans and lagoons in the sub-humid regions of Tasmania. The waters sampled are classed as fresh or saline, using a criterion which is a function of relative ionic composition. Saline waters are regarded as having ionic composition limited by the solubility of alkaline earth carbonates, and they have a composition akin to that of seawater. The fauna of salt pans is briefly mentioned. These analyses complete a survey of Tasmanian surface waters, and some relationships between ionic concentrations and other chemical parameters are reassessed for the entire salinity range (<10 ppm to > 200‰) of Tasmanian inland waters.

Abstract The zooplankton in South American saline waters is mainly dominated by copepods at salinities lower than 90 g/l, whereas at salinities above 90 g/l Artemia sp. is totally dominant. The aim of the present study is to analyse the salinity range of halophilic copepods on the basis of a literature review for South American saline inland waters. The calanoid Boeckella poopoensis Marsh, 1906, is widespread on the South American Altiplano and southern Argentinian plains, and in southern Patagonian shallow ponds. In the upper part of the salinity range, 20-90 g/l, B. poopoensis is the only copepod in the zooplankton of southern Patagonian and Altiplano shallow lakes. In the salinity range 5-20 g/l B. poopoensis may co-exist with B. palustris (Harding, 1955), two cyclopoids and an harpacticoid, and at salinities lower than 5 g/l it may co-exist with an even wider range of copepod species. Ecological and biogeographical aspects are also discussed.

Hydrographic Features

Zooplankton collections from two cruises to the Gulf of Alaska during 1954 and 1956 were studied to determine the species of Chaetognatha present, to establish their distribution within those waters, and to consider the distribution of the species with regard to certain general hydrographic features prevalent in the region at the time the collections were made. Also considered were a few collections made during the summer of 1958 in the waters surrounding San Juan Island in the San Juan Archipelago, Washington.The general oceanographic features of the Gulf of Alaska are described. The distributions and frequency of occurrence of 3 species of 2 genera of chaetognatha are described and discussed. Eukrohnia hamata is found at most off-shore stations, diminishing in number nearer the coast in less saline waters. Sagitta elegans is apparently cosmopolitan in the areas studied. S. lyra an oceanic form, was found in regions influenced by waters of the Subarctic Region and the American Coastal Region. The presence of S. lyra in inland waters of the San Juan Archipelago during the summer of 1958 is considered to be an indication of the shoreward movement of oceanic waters.

The present study was conducted in Salt marshes and Salt pans in central parts of Iran. 121 specimens of ants were collected by trapping and hand during spring, summer and autumn 2017 to 2019. Nine species belong to two subfamilies of Myrmicinae and Formicinae were identified. The vegetation, physical and chemical parameters of soil such as salinity, Ph, and other factors were investigated. Darband Shoor Mountain station with five species had the highest diversity and vegetation density and the lowest salinity of soil (72.14 ds/m) whereas Salt Lake station had only one species, with no vegetation and the highest salinity of soil (153.15 ds/m). Cataglyphis lividus (André, 1881) was the dominant species in all the stations except in Darband Shoor Mountain station. All the species were reported for the first time from salt marshes and salt pans in the central parts of Iran and were approved by Prof. Brian Taylor, in Royal Entomological Society of London, England.

A combination of membrane filtration, ion exchange, coprecipitation and thin-film X-ray fluorescence spectrometry was used to obtain data on the chemical speciation of iron, copper and zinc in surface waters, ranging in salinity from 0 to 30Ym, of the Hawkesbury River, N.S.W. Iron, the principal trace metal, was found mainly (>90%) in the particulate form. The dissolved (filterable) iron fraction was largely non-ion- exchangeable (colloidal) in the freshwater region and ion-exchangeable in saline waters (as hydrated ions or metal complexes that dissociate on the chelating resin column). Copper and zinc, by contrast, were almost entirely filterable over the whole salinity range, copper being 50-100% in the non-ion-exchangeable fraction, and zinc, 70-100% ion-exchangeable.

Although the majority of publications on extant nonmarine ostracode species in North America are concerned with lacustrine settings, many species that are potentially valuable as indicators of water quality changes live in non-lacustrine settings. Ostracode distributions in 157 springs, wetlands and streams in the United States are examined here in order to assess 1) species richness, 2) association with physical and chemical parameters of their habitats and 3) the presence of potentially useful biomonitors and environmental sentinels. The 157 non-lacustrine sites are a subset of a large database (North American Non-marine Ostracode Database: NANODe version 1) consisting of 611 mostly lacustrine sites with ostracode species, presence-absence data, hydrochemistry and climate data (Forester et al., in review). Of the 89 species represented in NANODe version 1, 51 species are found in springs, 59 species are found in wetlands and only 15 species are found in streams. Many species are found in at least two of these habitats and some in all three. Principal Components Analysis of these 157 sites indicates that 71% of the variance is explained by salinity (total ionic concentration), alkalinity and temperature, a result consistent with previously published analyses of natural water. Cluster analysis shows that spring species are most strongly tied to temperature, whereas wetlands and streams are most strongly tied to ionic composition. Three species are found to be potentially valuable biomonitors: Cavernocypris wardi in springs, Fabaeformiscandona rawsoni in wetlands and Physocypria globula in streams.

The surface waters of central Australia are briefly discussed. Analyses are presented of the ionic composition of some relatively non-saline and mostly permanent surface waters in the southern part of the Northern Territory. A brief note upon their fauna is included. Such waters are of interest because of their extreme isolation in so arid an area. They contain from 77 to 3735 p.p.m. total dissolved salts and their ionic ratios are variable. The ionic compositions are discussed.

Chemical data are presented for several lakes and two impoundments on the Kosciusko and Monaro plateaux in south-eastern New South Wales, and for two rivers (Paroo and Darling), several freshwater lakes, and deposits from some dry salt lakes in western New South Wales. The concentrations of the major cations and anions, nitrate plus nitrite, and orthophosphate were investigated. For lake deposits, only major ions were investigated. The Kosciusko lakes were extremely fresh (salinity <3 p.p.m.) and chemically dominated by sodium and either bicarbonate, chloride or sulphate ions ; the Monaro peneplain lakes had a considerable salinity range (69-21,244 p.p.m.), and, with increasing salinity, sodium and chloride quickly assumed dominance. The Paroo and Darling Rivers had salinities <400 p.p.m, and the western freshwater lakes <850 p.p.m.; in both rivers and lakes, sodium and bicarbonate were the dominant ions. Deposits from dry salt lakes were mainly sodium chloride.

Standard Deviations

Variability of total concentration and of ionic concentrations (measured as the standard deviations) is proportional to a power of the mean concentrations in 25 Tasmanian waters. Stoichiometric variability is low in saline waters and can be high in fresh waters. Climate is recognized as being of primary importance in affecting variability, although morphometric characters exert an influence. Geological conditions are an important factor in determining stoichiometric variability.

The global hydrological and salt cycles are described, as are the ways in which human activities have led to their disturbance. One effect of this disturbance is the unnatural increase in the salinity of many inland waters (secondary salinization). The geographical extent of secondary salinization is outlined, together with its effects on various types of inland waters, such as salt lakes, freshwater lakes and wetlands, and rivers and streams. The likely impact on salinization of global climate change is summarized.
