Global knowledge about the spatial distribution of species is orders of magnitude coarser in
resolution than other geographically-structured environmental datasets such as topography …

Habitat transformations caused by human land-use change are considered major drivers of
ongoing biodiversity loss,–, and their impact on biodiversity is expected to increase further …

Background Integrated, efficient, and global prioritization approaches are necessary to
manage the ongoing loss of species and their associated function." Evolutionary …

The vast scope of conservation problems has forced biologists and managers to rely on"
surrogate" species to serve as shortcuts to guide their decision making. These species …

Aim Biogeographical regionalizations, such as zoogeographical regions, floristic kingdoms
or ecoregions, represent categorizations central to many basic and applied questions in …

Over the past few decades, land-use and climate change have led to substantial range
contractions and species extinctions. Even more dramatic changes to global land cover are …

Most studies examining continental-to-global patterns of species richness rely on the
overlaying of extent-of-occurrence range maps. Because a species does not occur at all …

Climate change is predicted to be one of the greatest drivers of ecological change in the
coming century. Increases in temperature over the last century have clearly been linked to …

Conservation science depends on an accurate understanding of what's happening in a
given ecosystem. How many species live there? What is the makeup of the population? How …
