Review of proposed rule regarding status of the wolf under the Endangered Species Act

Geographical limits to species-range shifts are suggested by climate velocity

The reorganization of patterns of species diversity driven by anthro- pogenic climate change, and the consequences for humans1, are not yet fully understood or appreciated2,3. Nevertheless, changes in cli- mate conditions are useful for predicting shifts in species distribu- tions at global4 and local scales5. Here we use the velocity of climate change6,7 to derive spatial trajectories for climatic niches from 1960 to 2009 (ref. 7) and from 2006 to 2100, and use the properties of these trajectories to infer changes in species distributions.

A global analysis of the impacts of urbanization on bird and plant diversity reveals key anthropogenic drivers

Urbanization contributes to the loss of the world's biodiversity and the homogenization of its biota. However, comparative studies of urban biodiversity leading to robust generalities of the status and drivers of biodiversity in cities at the global scale are lacking. Here, we compiled the largest global dataset to date of two diverse taxa in cities: birds (54 cities) and plants (110 cities). We found that the majority of urban bird and plant species are native in the world's cities. Few plants and birds are cosmopolitan, the most common being Columba livia and Poa annua.
