Kinetics of 45Ca, 60Co, 210Pb, 54Mn and 109Cd in the tissue of the freshwater bivalve VeZesunio angusi: further development of a predictive and mechanistic model of metal bioaccumulation

Brown Paul; Jeffree Ross; Markich Scott (Elsevier Inc, 1996)

Abstract A theoretical and experimental study was performed to determine the kinetics of 45Ca, 6oCo, ¿`Pb, 54Mn and lo9Cd in the whole soft tissue of the unionid bivalve G/elesunio angasi. This investigation further tested ...
Land Cover Conversion and Degradation Analyses Through Coupled Soil-Plant Biophysical Parameters Derived From Hyperspectral EO-1 Hyperion

Huete Alfredo; Miura Tomoaki; Gao Xiang (IEEE, 2003)

Land degradation in semiarid areas results from various factors, including climate variations and human activity, and can lead to desertification. The process of degradation results in simultaneous and complex variations ...
Landscape of fear visible from space

Madin Elizabeth; Madin Joshua; Booth David (Nature, 2011)

By linking ecological theory with freely-available Google Earth satellite imagery, landscape-scale footprints of behavioural interactions between predators and prey can be observed remotely. A Google Earth image survey of ...
Larval development of the New Zealand geoduck panopea zelandica (Bivalvia Hiatellidae)

Gribben Paul; Hay Brenda (RSNZ Publishing, 2003)

The larval development of the New Zealand geoduck, Panopea zelandica, grown under culture conditions, was described through measurements of shell morphometry using video image analysis, photomicrographs, and ...
Latent Heat Fluxes During Two Contrasting Years From A Juvenile Plantation Established Over A Waste Disposal Landscape

Yunusa Isa; Fuentes S; Palmer Anthony; Macinnis-Ng Catriona; Zeppel Melanie; Eamus Derek (Elsevier Science Bv, 2011)

Revegetation to restore hydrological function to highly disturbed landscapes used for waste disposal or mining is often constrained by the initial low rates of water-use during the early phases of the developing vegetation. ...
Limitation Of Lowland Riverine Bacterioplankton By Dissolved Organic Carbon And Inorganic Nutrients

Westhorpe Douglas; Mitrovic Simon; Ryan Denise; Kobayashi T (Springer, 2010)

Flow regulation in lowland rivers has reduced the amount of allochthonous dissolved organic carbon (DOC) entering main channels through less frequent wetting of benches, flood runners and floodplains. The hypothesis tested ...
Linearization of NDVI based on its relationship with vegetation fraction

Jiang Z.; Huete Alfredo (ASPRS, 2010)

The Normalized Difference Vegetation Index (NDVI) is widely used for global monitoring of land surface vegetation dynamics from space. However, it is well documented that the NDVI approaches saturation asymptotically over ...
Magmatic changes during the stabilisation of a cordilleran fold belt: the Late Carboniferous Triassic igneous history of eastern New South Wales, Australia

Caprarelli Graziella; Leitch Evan (Elsevier Science BV, 1998)

In a 60 Ma interval between the Late Carboniferous and the Late Permian, the magmatic are associated with the cordilleran-type New England Fold Belt in northeast New South Wales shifted eastward and changed in trend from ...
Mass-transfer-limited nitrate uptake on a coral reef flat, Warraber island, Torres Strait, Australia

Baird Mark; Roughan Moninya; Middleton John; Nippard Greg (Springer, 2004)

Previous research has identified a relationship between the rate of dissipation of turbulent kinetic energy, e, and the mass-transfer-limited rate of uptake by a surface, herein called the epsilon(1/4) law, and suggests ...
Measurement and prediction of mass transfer to experimental coral reef communities

Baird Mark; Atkinson M (Amer Sco Limnology Oceanography, 1997)

The uptake of nutrients (N and P) into coral reef communities is proposed to be limited by diffusion through concentration-depleted boundary layers between the water and organisms, or what is termed "mass transfer limitation." ...
A mechanistic and predictive model of metal accumulation by the tissue of the Australian freshwater mussel Felesunio angasi

Jeffree Ross; Brown Paul (Elsevier Inc, 1992)

A mechanistic model explains the differential rates of accumulation of alkaline-earths in the tissue of the freshwater mussel Velesunio angasi as being determined by their different loss rates. These rates of loss are ...
Mesoscale and microscale spatial variability of bacteria and viruses during a Phaeocystis globosa bloom in the Eastern English Channel

Seymour Justin; Seuront L; Doubell M; Mitchel J (Elsevier, 2008)

Sampling was conducted within inshore and offshore sites, characterized by highly dissimilar hydrodynamic and hydrobiological conditions, in the Eastern English Channel. The eutrophic inshore site was dominated by the ...
Metal concentrations in macroalgae from East Antarctica

Runcie, J.; Riddle, M. J (Elsevier, 2005)
Methodology for bare soil detection and discrimination by Landsat TM image

Dematte Jose; Huete Alfredo; Ferreira L.; Nanni M.; Fiorio P. (Bentham Science Publishers, 2009)

The objective of this work was to develop and test a remote sensing technique to determine bare soils with pixel information from satellite images. The methodology was tested and improved on a 2,805 km2 area located in the ...
Micrometeorological fluxes under the influence of regional and local advection: a revisit

Lee Xuhui; Yu Qiang; Sun Xiaoming; Liu Jian-Dong; Min Qingwen; Liu Yunfen; Zhang Xianzhou (Elsevier Inc, 2004)

This paper presents a new analysis of inequality of eddy diffusivities for sensible heat (KH) and water vapor (KW). It is shown that the same set of equations, established on the principle of dual-source diffusion, can be ...
Microscale and small scale temporal dynamics of a coastal planktonic microbial community

Seymour Justin; Seuront Laurent; Mitchell J (Inter Research, 2005)

The temporal dynamics of heterotrophic bacteria and Synechococcus-type cyanobacteria communities were studied in a coastal habitat characterised by strong hydrodynamic variability using 10 s (microscale) and 30 min ...
Microscale gradients of planktonic microbial communities above the sediment surface in a mangrove estuary

Seymour Justin; Seuront L; Mitchell J (Elsevier, 2007)

The microscale (1 and 4 cm sampling resolution) distributions of chemical (O2, NH3, NO3-, NO2-, PO43-) and biological (Chl a, phytoplankton, bacterioplankton, viruses) parameters were measured in the 16 cm of water immediately ...
Microscopic structure of the mantle and palps in the freshwater mussels Velesunio ambigus and Hyridella depressa (Bivalvia : Hyriidae)

Colville Anne; Lim Richard (Elsevier, 2001)

There has been increasing interest in freshwater mussels (order Unionoida) in recent years because their numbers are declining in many parts of the world and also because they have potential as monitors of pollution. ...
Middle Ordovician conodonts from the Haedon Formation, northeastern New South Wales

Furey-Greig, T. (E. Schweizerbart'sche Verlagsbuchhandlung, 2004)

A fauna of 200 conodonts, assigned to seven species, was recovered from autochthonous and allochthonous limestones in the Haedon Formation, southwest of Woolom in, NE New South Wales. The fauna includes Ansella jemtlandica ...
