As climate change is expected to have a significant impact on species distributions, there is an urgent challenge to provide reliable information to guide conservation biodiversity policies. In addressing this challenge, we propose a remote sensing-based approach to forecast the future habitat quality for European badger, a species not abundant and at risk of local extinction in the arid enviro...
Insurance demand is driven by many factors, but for the emerging economies, one of the most significant historical drivers of growth has been income per capita. Based on a simple forecasting approach, we project that insurance penetration in the BRICS economies could increase at a rate of between 1.6 and 4.2% per year over the coming decade, depending on the country, due to rising per capita in...
Predictions of ecological response to climate change are based largely on direct climatic effects on species. We show that, in a California grassland, species interactions strongly influence responses to changing climate, overturning direct climatic effects within 5 years. We manipulated the seasonality and intensity of rainfall over large, replicate plots in accordance with projections of lead...
Climate change is currently considered a serious threat for many species and recognized as one of the most important factors in the global biodiversity loss. Among animal groups, amphibians are known to be among the most sensitive groups of vertebrates to climate change due to their inability to travel long distances, and mountain habitat species are more exposed to climate change pressures tha...
Cellular automata provide the key to a dynamic modelling and simulation framework that integrates socio-economic with environmental models, and that operates at both micro and macro geographical scales. An application to the problem of forecasting the effect of climate change on a small island state suggests that such modelling techniques could help planners and policy makers design more effect...
Predicting how species will respond to climate change is a growing field in marine ecology, yet knowledge of how to incorporate the uncertainty from future climate data into these predictions remains a significant challenge. To help overcome it, this review separates climate uncertainty into its three components (scenario uncertainty, model uncertainty, and internal model variability) and ident...
Conservative land-use over the past few decades has converted the Montseny Biosphere Reserve (Spain) from the original open, patchy landscape to almost continuous woodland. Small ruminant grazing is virtually the only major remaining utilisation activity yet little is known about its role in the changing vegetation of the Reserve. This study was undertaken to determine the effects of current gr...
