Annotation:

The present study investigates 45 natural and artificial water bodies extending across the whole of eastern Australia from the tropics to Tasmania. A broad variety of physio-chemical, land-use and climatic parameters were measured. Reservoirs and other artificial water bodies responded to stressors in their catchments in a similar fashion to natural lakes, but tended to be less nutrient rich, possibly because of shorter residence times and active management. Salinity and pH were strongly correlated in the dataset. Bedrock had a strong influence on pH in freshwater lakes, whereas all highly saline lakes were alkaline, irrespective of bedrock. High concentrations of anions in saline lakes precluded the existence of acid conditions by binding available hydrogen ions. Almost all lakes fell on salinity axes that indicated marine origin for their salts. An assessment of the total nitrogen to total phosphorus molar ratios from the lakes in the present dataset indicated that productivity in Australian lakes could be limited by both nitrogen and phosphorus. Future research using macro-nutrient enrichment experiments should be pursued to confirm this preliminary observation. There was a strong positive correlation between regional aridity and lake eutrophication. This is typical of semi-arid and seasonally arid environments and reflects the concentration of nutrients owing to evaporative flux in shallow basins with high residence times.

Salinity, temperature, dissolved oxygen (DO), pH and total alkalinity (TA) were measured in four saline lakes of Yalgorup National Park, Western Australia, primarily over an 18-month period, July 1985 to January 1987, but also during 1987 and in 1988. These lakes are shallow (<3 m) ground-water sinks with no surface drainage. Rainfall and hence ground-water inflow to the lakes was highly seasonal and occurred mainly between May and October. Lakes Hayward, North Newnham and South Newnham were consistently hypersaline (e.g. Hayward 61-214 g L-1) and Hayward and North Newnham were stratified from autumn to early summer. The bottom layer of water in Hayward was usually supersaturated (to 430%) with respect to DO, because of the photosynthetic activity of the benthic microbial communities (BMC). South Newnham did not stratify in 1985, but did so briefly in 1987 after a BMC developed. The salinity of Lake Pollard varied from 19 to 51 g L-1 and the lake did not stratify at all. During spring, extensive growth of the charophyte Lamprothamnium papulosum across the sediments in Lake Pollard increased DO (from c. 100% to c. 140% saturation) and pH (from c. 8.5 to c. lo), but lowered specific TA (from 0.26 to 0.075 meq L-1 per unit salinity); later removal of the L. papulosum by swans reduced DO to 50% saturation and pH to 7.5, and increased specific TA to 0.15 meq L-1 per unit salinity. It is apparent that the processes controlling Hayward, North Newnham and South Newnham are similar and are based on the activities of the BMC. South Newnham is at an earlier stage of evolution. However, Pollard is controlled primarily by L. papulosum growth and its subsequent removal by swans; this indicates a different evolutionary path for this lake.

Annotation:

All nine lakes studied are small (mean area 32 ha), shallow (< 5 m deep), watertable exposures in thin dunes overlying laterite or sandstone. Their water is fresh (mean salinity 52 mg I-1), acid (mean pH 4.8) and dominated by Na+ and Cl-, but with appreciable amounts of Ca2+, Mg2+ and HCO3-. Almost all macrophytes, littoral invertebrates, fish and limnetic zooplankters are common tropical species. A few species are shared with dune lakes in southern Australia and even fewer are endemic. Hence, these tropical dune lakes are different from those in temperate and subtropical eastern Australia.

Annotation:

Physical, chemical and biotic attributes of 16 lakes and ponds in the siliceous dunefields of Cape Flattery, in the humid tropics of Australia, have been investigated. The dune lakes are similar to those of dunefields in south-eastern Queensland, with very low to low conductivity (62-338 �S cm-1), low pH (3.9-6.8), and low to high humic content (gilvin 0.0-31.0 g440 m-1). These lakes are apparently not perched above the local water table. The ionic compositions of all lakes were very similar, with NaCl predominating and with very low concentrations of Mg, Ca, K, and SO4. Bicarbonate was absent or negligible in most lakes. The oligotrophic lakes are characterized by a desmid-diatom limnetic plankton of moderate diversity (12-35 species per lake). Of 144 taxa of phytoplankton recognized, 58% were desmids and 15% diatoms. The zooplankton was of low diversity and dominated by Calamoecia ultima. Twenty-nine species of aquatic macrophytes and 11 species of fish were recorded. Freshwater turtles (possibly Chelodina rugosa Ogilby), and the estuarine crocodile, Crocodylus porosus Schneider, were recorded from some lakes. Principal component analysis of chemical data distinguished three groups of lakes: a series of humic-stained ponds and lakes, a group of clear-water lakes with little or no humic staining, and a former barrier lagoon. Cluster analysis of the phytoplankton flora consistently segregated the clear-water lakes from humic-stained lakes but, in general, concordance of chemical, physiographic and biotic characteristics was poor. Existing classification schemes for Australian dune lakes, based on similar sets of physiographic, chemical and biotic data, do not cater well for the Cape Flattery lakes. A more useful classification may derive from consideration of the hydrological processes influencing their water balance and chemical characteristics.

Annotation:

Aspects of the morphometry and physical and chemical limnology of Yeppen Yeppen Lagoon, in tropical Australia, have been investigated. The lagoon is a channel billabong lying in the old bed of the Fitzroy River. It has a relatively small, shallow and elongated basin. Seasonal variations in water temperature, light regime, oxygen concentration, pH and conductivity suggest that the lagoon exhibits a warm monomictic pattern of thermal stratification rather than a continuous warm polymictic one. The annual heat budget was 3294 calories cm-2 year-1. Maximum work of the wind was 238.8 g-cm cm-2, and maximum stability was 34.5 g-cm cm-2. Despite the apparently low stability of stratification, the lagoon remained thermally stratified for much of the year. Analysis of wind-distributed heat suggested that slow mixing was taking place even during periods of relatively high stability, although this mixing was insufficient to reoxygenate the hypolimnion, which remained anoxic for much of the year. Yeppen Yeppen Lagoon is likely to prove eutrophic, and it is suggested that primary productivity will be high because a large volume of the lagoon's water is well lit and a large sediment surface area is in contact with the epilimnion. Notes on the biota of Yeppen Yeppen Lagoon are also given.

Annotation:

In the first months of 1981, the characteristically highly turbid Lake Alexandrina cleared somewhat so that turbidity dropped from a previous mean value (1975-1978) of 93 NTU to 9 NTU, the Secchi transparency and euphotic depth increased from previous means of 19 cm and 0.8 m to 72 cm and 3.1 m, and the light extinction coefficient fell from 6.54 to 1.2 In units m-1. Low flows in the River Murray, especially low contributions from the Darling River, and high salinity appeared to be the major factors responsible for the clearing. During the clear phase, nutrient levels fell, the normal summer peak of the ulotrichous green alga Planctonema lauterbornei failed to occur, there was a late summer-autumn bloom of blue greens especially Nodularia and Anabaena, and densities of the large microcrustaceans Boeckella triarticulata and Daphnia carinata were low. After flushing, the lake turbidity rose to previous high levels and over the period October 1981-April 1982 P. lauterbornei again dominated the phyto- plankton, chlorophyll a biomass reached 67 mg m-3, and the zooplankton community returned to its normal pattern of seasonality and abundance. The role of turbidity in controlling the physicochemical and biological conditions in the lake is discussed.

Small alpine water bodies can play a large role in defining patterns of biological and landscape diversity, and may be particularly sensitive to climate change. A large limnological dataset, consisting of 65 and 6 water bodies, respectively, on South Island and Stewart Island (New Zealand) and 76 and 12 water bodies, respectively, in the Tasmanian highlands and coastal areas (Australia), was constructed to assess patterns of variation in alpine and subalpine lakes in the Australasian region. With the exception of the coastal systems, most lakes were very dilute. In general, lake water chemistry resembled world average seawater cationic ratios (WASW). In addition, some New Zealand lakes fell close to the world average freshwater cationic ratios (WAFW), due to relatively high calcium concentrations, and some were dominated by magnesium due to the presence of serpentine bedrock in the catchment area. Multivariate analyses of the joint dataset revealed that the variation in chemical limnological variables was dominated by gradients in conductivity, pH and gilvin. The concurrent relationships between pH, calcium and gilvin, which enabled the differentiation of Tasmanian water bodies into limnological provinces, were absent in New Zealand. In the latter, pH and gilvin contents were not coincident, as clear-water acidic systems occurred in New Zealand. The higher diversity of freshwater bodies in New Zealand will enable independent assessment of the effects of pH and gilvin on the distribution and diversity of biota.

Abstract This is a contribution to the special issue honoring the late John R. Blake of the University of Birmingham. All three authors had the pleasure of extensive technical interactions with John Blake during his career in the UK, USA and Australia and benefited both professionally and personally from his friendship. John’s work in developing fundamental mathematical solutions for Stokes’ flows and his application of those mathematical tools to analyses of microorganism locomotion led to special new insights into the world of small-scale swimming. This special issue devoted to John’s memory seems an appropriate occasion to present another fluid mechanical challenge associated with microorganisms, namely the dynamics of algal blooms. Though it is a special reduced-order model that is of limited practical value, John would have particularly enjoyed the analytical solution to the dynamics of algae that was presented by Rutherford Aris (1997, Reflections on Keats’ equation. Chem. Eng. Sci., 52, 2447–2455) in a somewhat eccentric paper. We revisit that solution in this paper and present an extension to Aris’ solution that includes sedimentation of the algae. We think that John would have enjoyed this solution and would, in all likelihood, have been able to expand upon it to include other features such as microorganism buoyancy variations (see, e.g. Kromkamp & Walsby 1990; Belov & Giles, 1997, Dynamical model of buoyant cyanobacteria. Hydrobiologia, 349, 87–97; Brookes & Ganf, 2001, Variations in the buoyancy response of Microcystis aeruginosa to nitrogen, phosphorus and light. J. Plankton Res., 23, 1399–1411), the death of algae (see, e.g. Serizawa et al., 2008a, Computer simulations of seasonal outbreak and diurnal vertical migration of cyanobacteria. Limnology, 9, 185–194; Reynolds, 1984, The Ecology of Freshwater Phytoplankton. Cambridge University Press), the swimming of algae (see, e.g. Pedley, 2016, Spherical squirmers: models for swimming micro-organisms. IMA J. Appl. Math., 81, 488–521) and other relevant hydrodynamic matters.

Annotation:

During 1974-1984, Lake Buchanan and seven peripheral pools usually contained water for only a few months each year, commencing in late summer. They ranged in salinity from 1 to 202 g l-1, their waters were dominated by sodium chloride, but with Ca2+/Mg2+ ratios of c. 1, and were generally alkaline. The fauna of 53 species included three halobionts (e.g. Parartemia minuta, Diacypris compacts), 18 halophilics (e.g. Mytilocypris splendida, Trigonocypris globulosa, Microcyclops dengizicus) and many salt- tolerant freshwater forms, mainly insects. Overall, the fauna was distinctly Australian, but some prominent taxa found in southern salt lakes were absent and others were replaced by local endemics and tropical species. Past climatic cycles have probably influenced the composition of the fauna.

Annotation:

Mine pit lakes (‘pit lakes’) are new aquatic ecosystems of the Anthropocene. Potentially hundreds of meters deep, these lakes are prominent in the landscape and in the public consciousness. However, the ecology of pit lakes is underrepresented in the literature. The broad goal of this research was to determine the environmental drivers of pelagic microbe assemblages in Australian coal pit lakes. The overall experimental design was four lakes sampled three times, top and bottom, in 2019. Instrument chains were installed in lakes and measurements of in situ water quality and water samples for metals, metalloids, nutrients and microbe assemblage were collected. Lakes were monomictic and the timing of mixing was influenced by high rainfall events. Water quality and microbial assemblages varied significantly across space and time, and most taxa were rare. Lakes were moderately saline and circumneutral; Archeans were not prevalent. Richness also varied by catchment. Microbial assemblages correlated to environmental variables, and no one variable was consistently significant, spatially or temporally. Study lakes were dominated by ‘core’ taxa exhibiting temporal turnover likely driven by geography, water quality and interspecific competition, and the presence of water chemistry associated with an artificial aquifer likely influenced microbial community composition. Pit lakes are deceptively complex aquatic ecosystems that host equally complex pelagic microbial communities. This research established links between microbial assemblages and environmental variables in pit lakes and determined core communities; the first steps towards developing a monitoring program using microbes.

Annotation:

Fertilization of earthen ponds used to rear the larvae of golden perch, Macquaria ambigua, and silver perch, Bidyanus bidyanus, resulted in phytoplankton blooms dominated by the cyanobacterium Anabaena possibly because of a low N:P ratio. There was a zooplankton succession of rotifers (mostly Brachionus), Moina, Boeckella and Mesocyclops, and then Daphnia. An increase in Daphnia correlated with a decline in Anabaena, suggesting grazing on that cyanobacterium. Golden perch larvae included copepods in their diet whereas silver perch did not, and this was reflected in lower Boeckella numbers in the golden perch ponds. There was sufficient zooplankton forage, supplemented by chironomid larvae in the later stages of the rearing ponds, for fish growth. The limnological conditions and zooplankton communities in these ponds provide a model for evaluating nursery grounds for these fish.

This study determined the seasonal variability of free-living nematode communities structure (genus/family level) in organic shrimp farms ponds in Tam Giang commune, Nam Can district, Ca Mau province. Based on the result of SIMPER analysis, the average similarity in nematode communities at genus level was low with 30.75% and 30.81% (in dry and rainy season, respectively). However, the average dissimilarity between seasons was considerably high with 71.75%. Terschellingia, Daptonema, and Parodontophora were main genera contributing to similarity/dissimilarity between seasons. At the family level, results of SIMPER analysis showed that the average similarity was low with 37.12% and 39.02% (dry and rainy, respectively). Additionally, the average dissimilarity between dry and rainy season was fairly high with 64.06%. Specifically, four families such as Linhomoeidae, Xyalidae, Axonolaimidae, and Chromadoridae were the main families contributing to similarity/dissimilarity between seasons. Differences in sediment environmental characteristics between dry and rainy season are the reason for dissimilarity in the nematode communities structure. The high abundance of genus Terschellingia, Daptonema, Parodontophora may be indicative of organic enrichment conditions in shrimp pond sediment in both seasons. Nematodes with their rapid adaptation to changing environments can be used as a potential tool for bio-indicator.
