Identifying suitable reference points is critical for effective monitoring of any natural system. Here we utilize a comparative approach where putative impacts within two estuaries are determined via comparison with two reference estuaries deemed to be relatively free of human impacts. The two putatively impacted estuaries considered in this study were the Duck and Montagu River estuaries situated on the NW coast of Tasmania. The river catchments of these estuaries are typical of the… Expand
The effects of catchment landuse on estuaries - using macroinvertebrates as bio-indicators
Benthic macroinvertebrates are often used bio-indicators of pollution as they readily respond to changes in their environment. However, within estuaries natural variation in macrofaunal assemblagesExpand
Geomorphology report on coastal erosion at the Detention River estuary, Hellyer, North-West Tasmania
The western bank of the Detention River estuary has in the last few years suffered erosion owing to the active estuarine channel meandering to the west. The main estuarine channel was located inExpand


The conservation significance of estuaries: a classification of Tasmanian estuaries using ecological, physical and demographic attributes as a case study
Estuaries arguably represent the most anthropogenically-degraded habitat-type on earth, with few estuaries in temperate and tropical regions existing in a near pristine state. Conservation ofExpand
Can the nitrogen and carbon stable isotopes of the pygmy mussel,Xenostrobus securis, indicate catchment disturbance for estuaries in northern New South Wales, Australia?
The nitrogen and carbon stable isotope ratios (δ15N and δ13C) of the pygmy mussel,Xenostrobus securis, were determined for three estuaries with varying levels of catchment disturbance in northern NewExpand
Coupling of estuarine benthic and pelagic food webs to land-derived nitrogen sources in Waquoit Bay, Massachusetts, USA
The fact that land-derived sources of nutrients promote eutrophication in the receiving coastal waters implies coupling between land and marine environments. Increasing nitrogen inputs in theExpand
Carbon and nitrogen stable isotope analysis of three types of oyster tissue in an impacted estuary
The stable isotope ratios of carbon (d 13 C) and nitrogen (d 15 N) of the muscle, ctenidia and viscera of the Sydney rock oyster, Saccostrea glomerata, showed the dilution and assimilation ofExpand
Stable isotopes as tracers of organic matter input and transfer in benthic food webs: A review
Abstract Some of the ways that the application of stable isotopic tracers have contributed to the extremely hard task of understanding the energy and food web relations in benthic communities areExpand
