The Influence Of Seabird-Derived Nutrients On Island Ecosystems In The Oligotrophic Marine Waters Of South-Western Australia, Sofie A. Harrison Jan 2006

The Influence Of Seabird-Derived Nutrients On Island Ecosystems In The Oligotrophic Marine Waters Of South-Western Australia, Sofie A. Harrison

Theses: Doctorates and Masters

Nutrient inputs from productive marine environments have been shown to directly and indirectly subsidise primary producers and consumers in terrestrial ecosystems (e.g. Polis and Hurd 1995; 1996; Anderson and Polis 1998; 1999). But does this theory hold true on islands surrounded by oligotrophic waters, which account for a significant proportion of the marine environment? The aim of the present study was to examine the applicability of the spatial subsidisation hypotheses proposed by Polis and his co-authors to an oligotrophic system in south-western region of Western Australia. These aims were achieved by comparing soil and plant nutrients, and the nitrogen stable …

The Hillarys Transect (1): Seasonal And Cross-Shelf Variability Of Physical And Chemical Water Properties Off Perth, Western Australia, 1996-98, Alan Pearce, Mervyn Lynch, Christine Hanson

Research outputs pre 2011

A 27-month study of the water properties across the continental shelf off Perth, Western Australia (the "Hillarys Transect") has provided the first systematic inter-disciplinary climatology of the physical, chemical, optical and biological cycles across the shelf. This paper describes the main features of the seasonal and cross-shelf variability of the physical oceanography and chemistry, while companion papers discuss some of the links between the biology and physics of the region
