Climate change will cause Europe to lose much of its biodiversity as projected by a comprehensive study on future butterfly distribution. The Climatic Risk Atlas of European Butterflies predicts northward shifts in potential distribution area of many European butterfly species. As early warning indicators of environmental change, butterflies are a valuable tool to assess overall climate change impact and to provide some indication on the chances to come nearer to the target of halting the loss of biodiversity by 2010 set by the EU Heads of State in 2001. The Climatic Risk Atlas of European Butterflies is based on the work of scores of scientists from across Europe. They applied climate change models to data collected by tens of thousands of volunteers. The authors say that some climate change is now inevitable and that the extent of the losses will depend on the degree of that change and how we respond to the new threat. Butterflies have already suffered huge losses across Europe following decades of habitat loss and changing farming and forestry practices. As temperatures rise, majority of butterfly species will try to head north. This won't always be achievable. The forestry and farming changes mean that areas of suitable habitat are now often small and too far apart for butterflies to travel between them. The worst-case scenario scientists examined sees the average European temperature rise by 4.1°C by 2080. In that case over 95 per cent of the present land occupied by 70 different butterflies would become too warm for continued survival. The best case-scenario sees a 2.4°C temperature rise. Even this would mean that 50 per cent of the land occupied by 147 different butterflies would become too warm for them to continue to exist there. Many butterflies will largely disappear from where they are regularly seen now. The Small Tortoiseshell will become absent from a huge swathe of middle and southern Europe and will become restricted to northern Europe. Under the worst-case scenario, rare species like the Spanish Festoon Zerynthia rumina would experience a 97% loss from Spain and Southern France, and the Apollo Parnassius apollo would suffer a 76% loss from mountainous areas. Climate change is already having an impact on butterflies. Over 60 mobile species with widespread food-plants are known to have spread north in Europe over recent decades, including the Comma Polygonia c-album, which is spreading north in the UK at 10km per year. Other species have moved further up mountains. The chief author of Climatic Atlas of European Butterflies is Dr Josef Settele from the Helmholtz Centre for Environmental Research (UFZ) in Germany. He said: "The Atlas shows for the first time how the majority of European butterflies might respond to climate change. Most species will have to shift their distribution radically to keep pace with the changes. The way butterflies change will indicate the possible response of many other insects, which collectively comprise over two-thirds of all species." Dr Martin Warren, Chairman of Butterfly Conservation Europe and one of the authors, said "Evidence points to an acceleration in climate change after 2050 unless there is a significant decrease in global CO2 emissions. This accelerated change would be the final nail in the coffin for many European species. We need to be ready for this worst-case scenario. We need place more emphasis on maintaining large, diverse populations on existing habitats while re-connecting habitats to allow species to move across the landscape. This means working closely with farmers and planners." Dr Ladislav Miko, Director of Nature Conservation at the EU Environment Directorate in Brussels, said: "We strongly welcome this important study which helps us understand how species might respond to climate change. The evidence points to a radical change in species' distribution, which we must plan for within future European policies. The results show the enormous scientific value of records from thousands of volunteers across Europe." Sebastian Winkler, Head of Countdown 2010, stated "The astounding outcomes of this study should remind world leaders once more that if immediate action is not taken, the 2010 biodiversity target will not be reached and biological diversity will continue to decline."

The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

A term with myriad associations, revolution is commonly understood in its intellectual, historical, and sociopolitical contexts. Until now, almost no attention has been paid to revolution and questions of geography. Geography and Revolution examines the ways that place and space matter in a variety of revolutionary situations. David N. Livingstone and Charles W. J. Withers assemble a set of essays that are themselves revolutionary in uncovering not only the geography of revolutions but the role of geography in revolutions. Here, scientific revolutions—Copernican, Newtonian, and Darwinian—ordinarily thought of as placeless, are revealed to be rooted in specific sites and spaces. Technical revolutions—the advent of print, time-keeping, and photography—emerge as inventions that transformed the world's order without homogenizing it. Political revolutions—in France, England, Germany, and the United States—are notable for their debates on the nature of political institutions and national identity. Gathering insight from geographers, historians, and historians of science, Geography and Revolution is an invitation to take the where as seriously as the who and the when in examining the nature, shape, and location of revolutions.

In Geographies of Nineteenth-Century Science, David N. Livingstone and Charles W. J. Withers gather essays that deftly navigate the spaces of science in this significant period and reveal how each is embedded in wider systems of meaning, authority, and identity. Chapters from a distinguished range of contributors explore the places of creation, the paths of knowledge transmission and reception, and the import of exchange networks at various scales. Studies range from the inspection of the places of London science, which show how different scientific sites operated different moral and epistemic economies, to the scrutiny of the ways in which the museum space of the Smithsonian Institution and the expansive space of the American West produced science and framed geographical understanding. This volume makes clear that the science of this era varied in its constitution and reputation in relation to place and personnel, in its nature by virtue of its different epistemic practices, in its audiences, and in the ways in which it was put to work.
