The impact of global phosphorus scarcity on food security has increasingly been the focus of scientific studies over the past decade. However, systematic analyses of alternative futures for phosphorus supply and demand throughout the food system are still rare and provide limited inclusion of key stakeholders. Addressing global phosphorus scarcity requires an integrated approach exploring poten...

North Queensland is a major repository of biodiversity in Australia. From the perspective of industry proponents, the impacts of plantation developments on biodiversity deserve consideration because these impacts are likely to influence public acceptance of proposals and whether proposals can attract environmentally-linked funding and marketing opportunities. At the same time, plantations offer...

Dated molecular phylogenies are often used to interpret evolutionary history with respect to paleogeographic events. Where more than one interpretation is possible, it is desirable but difficult to assess the alternatives in an objective manner. The present work demonstrates a formalized method for testing molecular clock calibrations and biogeographic scenarios based on them. We assessed the p...

This paper develops and analyzes four energy scenarios for California that are both exploratory and quantitative. The businessas-usual scenario represents a pathway guided by outcomes and expectations emerging from California’s energy crisis. Three alternative scenarios represent contexts where clean energy plays a greater role in California’s energy system: Split Public is driven by local and ...

Over the last decade we have seen considerable change in social values and forest ecosystem knowledge triggering a plethora of complex forest management alternatives. Planning and forecasting the economic, social and environmental consequences of these options requires sophisticated computer models, which are seldom easy to understand. This paper describes how an interdisciplinary team integrat...
