Temporal and spatial variability in the phytoplankton community of Myall Lakes, Australia and influences of salinity

Ryan Natasha; Mitrovic Simon; Bowling Lee (Springer, 2008)

The variability in the phytoplankton communities of the Myall Lakes, a series of four interconnected coastal lakes on the lower north coast of New South Wales, was studied between 1999 and 2002. There was considerable ...
Three-dimensional structure of a swarm of the salp Thalia democratica within a cold-core eddy off southeast Australia

Baird Mark; Everett Jason; Suthers Iain (American Geophysical Union, 2011)

Swarms of the salp Thalia democratica periodically occur off southeast Australia following the austral spring bloom of phytoplankton. In October 2008 a filament of upwelled water was advected south by the adjacent East ...
Topographic controls on the invasion of Pteronia incana (blue bush) onto hillslopes in Ngnushwa (formerly Peddie) district Eastern Cape South Africa.

Kakembo Vincent; Rowntree K; Palmer Anthony (Elsevier, 2007)

The role of topographic factors in the invasion of hillslopes by Pteronia incana, an unpalatable shrub, was investigated. The study combined field observations with image analysis based on high-resolution infrared imagery. ...
Towards an understanding of coupled physical and biological processes in the cultivated Sahel ¿ 1. Energy and water

Ramier D.; Boulain Nicolas; Cappelaere B.; Timouk F.; Rabanit Manon; Lloyd J.; Boubkraoui Stã©Phane; Mã©Tayer Frã©Dã©Ric; Descroix Luc; Wawrzyniak Vincent (Elsevier BV, 2009)

This paper presents an analysis of the coupled cycling of energy and water by semi-arid Sahelian surfaces, based on two years of continuous vertical flux measurements from two homogeneous recording stations in the Wankama ...
Trans-dimensional inverse problems, model comparison and the evidence

Sambridge Malcolm; Gallagher Kerry; Jackson Andrew; Rickwood Peter (Wiley-Blackwell, 2006)

In most geophysical inverse problems the properties of interest are parametrized using a fixed number of unknowns. In some cases arguments can be used to bound the maximum number of parameters that need to be considered. ...
The trophic history of Myall Lakes, New South Wales, Australia: interpretations using delta C-13 and delta N-15 of the sedimentary record

Drew Simon; Flett Iona; Wilson Joanne; Heijnis Henk; Skilbeck Charles (Springer, 2008)

In an attempt to determine the trophic history of the Myall Lakes complex ( New South Wales, Australia) delta C-13(org), delta N-15 and C-org: N profiles were determined for bulk organic matter of two short sediment cores ...
Trophic linkages between periphyton and grazing macroinvertebrates in rivers with different levels of catchment development

Chessman Bruce; Westhorpe Douglas; Mitrovic Simon; Hardwick Lorraine (Springer, 2009)

In December 1999, domoic acid (DA) a potent neurotoxin, responsible for the syndrome Amnesic Shellfish Poisoning (ASP) was detected for the first time in shellfish harvested in Ireland. Two liquid chromatography (LC) methods ...
Uptake kinetics and assimilation of phosphorus by Catenella nipae and Ulva lactuca can be used to indicate ambient phosphate availability

Larkum, A. W.; Ritchie, R. J; Runcie, J. (Kluwer Academic Publishers, 2004)

Uptake, assimilation and compartmentation of phosphate were studied in the opportunist green macroalga Ulva lactuca and the estuarine red algal epiphyte Catenella nipae. The Michaelis-Menten model was used to describe ...
The Urban Emergence of a New Information Industry: Sydney's Multimedia Firms

Searle Glen; De Valence Gerard (Blackwell Publishing, 2005)

This paper analyses the multimedia industry in Sydney. It seeks to understand whether the emergence of the industry has involved dense horizontal and vertical inter-firm linkages characteristic of an industrial cluster, ...
The use of mechanistic descriptions of algal growth and zooplankton grazing in an estuarine eutrophication model

Baird Mark; Walker Samuel; Wallace B; Webster I; Parslow J (Academic Press, 2003)

A simple model of estuarine eutrophication is built on biomechanical (or mechanistic) descriptions of a number of the key ecological processes in estuaries. Mechanistically described processes include the nutrient uptake ...
Using enhanced knowledge of climate variability for adapting to climate change in water resource management in South Africa

Ziervogel Gina; Johnston Peter; Matthew Margaret; Mukheibir Pierre (Springer, 2010)

Water resources, and in particular run-off, are significantly affected by climate variability. At present, there are few examples of how the water management sector integrates information about changing intra-annual climate ...
Using rain-use-efficiency to explore livestock production trends in rangelands in the Transkei, South Africa

Palmer Anthony; Ainslie Andrew (National Inquiry Services Centre, 2007)

We qualitatively describe the condition of communally managed rangelands in the Transkei, South Africa, using GIS and high resolution near-infrared imagery. Using livestock census data from 28 magisterial districts in the ...
Using silicone passive samplers to detect polycyclic aromatic hydrocarbons from wildfires in streams and effect assessment for invertebrate communities

Schafer R; Hearn L; Kefford Benjamin; Mueller J; Nugegoda Dayanthi (Pergamon, 2010)

Silicone rubber passive samplers spiked with 4 deuterated performance reference compounds were deployed for 29¿33 days to estimate the concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) in 9 streams in Victoria, ...
Using stable water isotopes to evaluate basin-scale simulations of surface water budgets

Henderson-Sellers Ann; Mcguffie Kendal; Noone D; Irannejad Parvis (American Meteorological Society, 2004)

Two rare but naturally occurring isotopes of water. 1H2 18O and 1H2H16O, are becoming of practical use in diagnosis of climate and earth system model performance. Their value as tracers and validation tools in ...
Vegetation detection through smoke-filled A VIRIS images: an assessment using MODIS band passes

Miura Tomoaki; Huete Alfredo; Van Leeuwen J; Didan Kamel (Amer Geophysical Union, 1998)

Abstract. Radiomelrtcally calibrated, Airborne Visible Infrared Imaging SpectromeIer (AVIRIS) images acquired during the Smoke, Clouds and Radiation in Brazil (SCAR-B) experiment were processed to simulate vegetation index ...
Vegetation Index methods for estimating evapotranspiration by remote sensing

Glenn E.P; Nagler P. L; Huete Alfredo (Springer, 2010)

Evapotranspiration (ET) is the largest term after precipitation in terrestrial water budgets. Accurate estimates of ET are needed for numerous agricultural and natural resource management tasks and to project changes in ...
Warmer more acidic conditions cause decreased productivity and calcification in subtropical coral reef sediment-dwelling calcifiers

Sinutok Sutinee; Hill Ross; Doblin Martina; Wuhrer Richard; Ralph Peter (Amer Soc Limnology and Oceanography, 2011)
