The three largest sewage outfalls serving Sydney, New South Wales, Australia are to be moved several kilometres offshore in 1991-2. Changes in their environmental impact due to these moves are likely, but detection relies on a good understanding of the present impacts on the natural environment. Biological surveys in 1986-8 of rocky intertidal sites located(More)
An understanding of risks to biodiversity is needed for planning action to slow current rates of decline and secure ecosystem services for future human use. Although the IUCN Red List criteria provide an effective assessment protocol for species, a standard global assessment of risks to higher levels of biodiversity is currently limited. In 2008, IUCN(More)
Many marine invertebrates have a planktonic stage of their life history during which widespread dispersal and much mortality occur. The numbers surviving to recruit into habitats occupied by adults are therefore very variable in time and space. Models for the structure and dynamics of benthic assemblages tend to focus on processes causing death - often(More)

Recent work in marine ecology has reaffirmed an insight from fisheries science that knowledge about the production, dissemination and success of propagules can guide our management of populations and assemblages. Understanding the variable nature of recruitment relationships can both aid and hinder attempts at environmental monitoring, rehabilitation and(More)
Older adults differ from younger ones in the ways they experience the World Wide Web. For example, they tend to move from page to page more slowly, take more time to complete tasks, make more repeated visits to pages, and take more time to select link targets than their younger counterparts. These differences are consistent with the physical and cognitive(More)
This paper considers different ways to enhance access to the World Wide Web for persons with sensory, cognitive, or motor limitations. Paradoxically, while complex Web architectures may seem to have inhibited accessibility, they have broadened the range of points where we can try to improve it. This paper identifies these points and evaluates the advantages(More)
