Item Open Access Effects of removal of seagrass canopy on assemblages of small motile invertebrates(Inter-research, 1995) Connolly, Roderick Martin; Department of ZoologyTo test the importance of seagrass canopy to epifaunal invertebrates in a southern Australian estuary, patches of the short, fine-leaved seagrass Zostera muelleri Irmisch ex Aschers. were cleared of canopy. All other factors were known to be consistent with seagrass presence, and a procedural control was used to measure any effects of the method used to remove seagrass. Effects on epifauna were measured as changes in abundance and biomass of key taxa and in total production, and as differences amongst assemblages, tested using an analysis of similarity (ANOSIM) randomisation routine. Removal of seagrass canopy had a weak but detectable effect on epifauna over and above the slight effect caused by the disturbance concomitant with seagrass removal. Epifauna associated with habitat from which seagrass had been removed did not, however, match that from areas unvegetated prior to the experiment. The epifauna from these previously unvegetated areas were characterised by low abundance and biomass of several key taxa, apart from 1 group, cumaceans, which were far more common in this habitat. The results suggest that the overriding importance of Z. muelleri to epifauna is not simply the presence of seagrass canopy, and explanations of the higher abundance of epifaunal invertebrates in vegetated compared to unvegetated habitats based merely on the presence of seagrass canopy are not supported.Item Metadata only Effects of flow regulation on the flow regime of the River Murray(Wiley, 1995) Maheshwari, B.; Walker, K.Item Metadata only Macroinvertebrates in salt lakes of the Bolivian Altiplana(Kluwer Academic, 1995) Williams, William David; Carrick, T.; Bayly, Ian A.

In highly saline waters, however, salt effects due to ionic strength, or to particular ions present, may result in method interferences. Three methods of analysis of phosphate based on the formation of phosphomolybdenum blue complexes have been evaluated here for hypersaline waters. Stannous chloride reduction in aqueous media exhibits a substantial salt effect and its use is not recommended. Stannous chloride reduction following extraction into non aqueous solvents shows a significant salt effect (up to 30 per cent) in solutions of salinity >100 g L−1. Dilution of hypersaline waters to below this salinity may overcome the salt effect but the method suffers from other disadvantages involving resource constraints and health and safety considerations. Ascorbic acid reduction, catalysed by antimony (III) ions, appears to offer the most promise for hypersaline waters. Turbidity in samples having high salinity (> 100 g L−1) and high phosphorus concentrations (> 500 μg P L−1) changes the spectral characteristics of solutions but linear calibration curves still result for concentrations in the range 400 to 1,000 μg P L−1. The occurrence of turbidity is also affected by the ionic composition of hypersaline waters since solutions made from sea salt give different results to those made from sodium chloride. Dilution of samples, to give salinities less than 100 g L−1 prior to reduction is recommended to avoid turbidity. The salt effect in these lower salinity waters is less than 3 per cent up to 100 g L−1.Item Metadata only Oxygen uptake by embryos in gelatinous egg masses of Rana sylvatica: The roles of diffusion and convection(American Society of Ichthyologists and Herpetologists, 1995) Seymour, R.Item Metadata only Frogs and toads(University of Queensland, 1995) Tyler, M.Item Metadata only A field guide to Australian Frogs.(Surrey Beatty, 1995) Barker, J.; Grigg, G.; Tyler, M.This revised edition includes details of 50 new species discovered since the original edition was published. The guide is divided into four chapters: evolution, taxonomy and zoogeography of frogs; biology of frogs; the Australian frogs; and collecting, keeping and photographing frogs. Chapter 3 presents ecological notes, distribution maps, photographs and identification keys to the five families represented in Australia. -L.E.EvansItem Metadata only Sabanes: La vida en rius i llacs(Enciclopedia Catalonica, MAB, UNESCO, 1995) Williams, William David; School of Earth and Environmental Sciences : Ecology and Evolutionary BiologyItem Metadata only Diet of juvenile King George whiting Sillaaginodes punctata (Pisces: Sillaginidae) in the Barker Inlet - Port River estuary, South Australia(Royal Society of South Australia Incorporated, 1995) Connolly, R.
