Identifying conflict potential in a coastal and marine environment using participatory mapping.

Planning for coastal and marine environments is often characterized by conflict over current and proposed uses. Marine spatial planning has been proposed as a way forward, however, social data are often missing impeding decision-making. Participatory mapping, a technique useful for providing social data and predict conflict potential, is being used in an increasing number of terrestrial applications to inform planning, but has been little used in the marine realm.

Scenario analysis for biodiversity conservation: a social-ecological system approach in the Australian Alps.

Current policy interventions are having limited success in addressing the ongoing decline in global biodiversity. In part, this is attributable to insufficient attention being paid to the social and governance processes that drive decisions and can undermine their implementation. Scenario planning that draws on social-ecological systems (SES) analysis provides a useful means to systematically explore and anticipate future uncertainties regarding the interaction between humans and biodiversity outcomes.

Galantamine inhibits beta-amyloid aggregation and cytotoxicity.

The ability of galantamine (Reminyl) to inhibit the aggregation and toxicity of the beta-amyloid peptide (Abeta) was investigated. Galantamine showed concentration-dependent inhibition of aggregation of both Abeta 1-40 and Abeta 1-42, as determined by an ELISA method. Electron microscope studies of Abeta 1-40 incubated in the presence of galantamine revealed fibrils that were disordered and clumped in appearance.

Diversity in current ecological thinking: implications for environmental management.

Current ecological thinking emphasizes that systems are complex, dynamic, and unpredictable across space and time. What is the diversity in interpretation of these ideas among today's ecologists, and what does this mean for environmental management? This study used a Policy Delphi survey of ecologists to explore their perspectives on a number of current topics in ecology. The results showed general concurrence with nonequilibrium views.

Importance of public information and perception for managing recreational activities in the Peel-Harvey estuary, Western Australia.

Surveys of water recreational activities were conducted in the Peel-Harvey estuary. Channels used by recreationists to gain information about water quality, the perception of water quality and resulting behaviour were investigated. This study showed that personal perception, local knowledge and history, absence of warnings and residency were major factors contributing to risk perception and behaviour in this recreational community.

Defining indicators and standards for tourism impacts in protected areas: Cape Range National Park, Australia.

Visitors' perceptions of impacts and acceptable standards for environmental conditions can provide essential information for the sustainable management of tourist destinations, especially protected areas. To this end, visitor surveys were administered during the peak visitor season in Cape Range National Park, on the northwest coast of Western Australia and adjacent to the iconic Ningaloo Reef. The central focus was visitors' perceptions regarding environmental conditions and standards for potential indicators.

Do we all face the same risk when bathing in the estuary?

With the development of coastal areas, microbial water quality is an emerging public health issue though few studies have focused on risks according to age. A survey was undertaken of faecal contamination in relation to recreational activities in the Peel Harvey estuarine system, Western Australia. Levels of exposure to contaminated water were estimated though social surveys.

Both the D-(+) and L-(-) enantiomers of nicotine inhibit Abeta aggregation and cytotoxicity.

The underlying cause of Alzheimer's disease is thought to be the aggregation of monomeric beta-amyloid (Abeta), through a series of toxic oligomers, which forms the mature amyloid fibrils that accumulate at the center of senile plaques. It has been reported that L-(-)-nicotine prevents Abeta aggregation and toxicity, and inhibits senile plaque formation. Previous NMR studies have suggested that this could be due to the specific binding of L-(-)-nicotine to histidine residues (His6, His13, and His14) in the peptide.
