A Significant Upward Shift in Plant Species Optimum Elevation During the 20th Century
This study shows that climate warming has resulted in a significant upward shift in species optimum elevation averaging 29 meters per decade, which is larger for species restricted to mountain habitats and for grassy species, which are characterized by faster population turnover.
Species abundance distributions: moving beyond single prediction theories to integration within an ecological framework.
Theoretical, empirical and statistical developments in the study of Species abundance distributions are reviewed and it is optimistic that SADs can provide significant insights into basic and applied ecological science.
Effectiveness of the global protected area network in representing species diversity
It is shown that the global network of protected areas is far from complete, and the inadequacy of uniform—that is, ‘one size fits all’—conservation targets is demonstrated, in the first global gap analysis assessing the effectiveness ofprotected areas in representing species diversity.
Approaching a state shift in Earth’s biosphere
Evidence that the global ecosystem as a whole is approaching a planetary-scale critical transition as a result of human influence is reviewed, highlighting the need to improve biological forecasting by detecting early warning signs of critical transitions.
Extinction Thresholds and Metapopulation Persistence in Dynamic Landscapes

A lattice metapopulation model, of the patch occupancy type, based on interacting particle systems that incorporate explicitly both metAPopulation and patch dynamics is developed, and how extinction thresholds are quantitatively overestimated by the MF equations is shown.
Body mass of late Quaternary mammals
The purpose of this data set was to compile body mass information for all mammals on Earth so that we could investigate the patterns of body mass seen across geographic and taxonomic space and…
Global Gap Analysis: Priority Regions for Expanding the Global Protected-Area Network
Abstract Protected areas are the single most important conservation tool. The global protected-area network has grown substantially in recent decades, now occupying 11.5% of Earth's land surface, but…
Evolution of Body Size: Consequences of an Energetic Definition of Fitness
A general model for the effect of body size on fitness is developed and predicts the distinctive right-skewed shape of the frequency distribution of logarithms of body sizes among species that is observed in a wide variety of organisms from bacteria to mammals.
Parasites in food webs: the ultimate missing links
Parasitism is the most common consumer strategy among organisms, yet only recently has there been a call for the inclusion of infectious disease agents in food webs. The value of this effort hinges…

It is demonstrated that, on a global scale, the impacts of climate change on viticultural suitability are substantial, leading to possible conservation conflicts in land use and freshwater ecosystems.
