Decentring 1788: Beyond Biotic Nativeness, Lesley M. Head
Decentring 1788: Beyond Biotic Nativeness, Lesley M. Head
Lesley Head
The usefulness of the concept of biotic nativeness has been challenged in both the social and natural sciences, for different reasons. This paper explores the particular construction of nativeness in Australia in relation to plants, showing that the definition builds on and inscribes more deeply the boundary between humans and the rest of nature seen in the wider literature. In this context two further boundaries are etched: between some humans and others, and before and after European colonisation. Such a use of nativeness as an axiom of environmental management is argued to be problematic, foreclosing a number of future options …

Microalgae are sensitive indicators of environmental change and, as the basis of most freshwater and marine ecosystems, are widely used in the assessment of risk and development of environmental regulations for metals. However, interspecies differences in sensitivity to metals are not well understood. The relationship between metal-algal cell binding and copper sensitivity of marine microalgae was investigated using a series of 72-h growth-rate inhibition bioassays and short-term (1-h) uptake studies. A range of marine algae from different taxonomic groups were screened to determine whether copper adsorption to the cell membrane was influenced by biotic factors, such as the ultrastructure of …
