Phylogenetic and functional diversity in large carnivore assemblages
-
Large terrestrial carnivores are important ecological components and promi- nent flagship species, but are often extinction prone owing to a combination of biological traits and high levels of human persecution. This study com- bines phylogenetic and functional diversity evaluations of global and continental large carnivore assemblages to provide a framework for conser- vation prioritization both between and within assemblages. Species-rich assemblages of large carnivores simultaneously had high phylogenetic and functional diversity, but species contributions to phylogenetic and func- tional diversity components were not positively correlated. The results further provide ecological justification for the largest carnivore species as a focus for conservation action, and suggests that range contraction is a likely cause of diminishing carnivore ecosystem function. This study high- lights that preserving species-rich carnivore assemblages will capture both high phylogenetic and functional diversity, but that prioritizing species within assemblages will involve trade-offs between optimizing contempor- ary ecosystem function versus the evolutionary potential for future ecosystem performance.

WWF : A CLOSING WINDOW OF OPPORTUNITY - GLOBAL GREENHOUSE REALITY 2008
-
Scientific evidence accumulating since the IPCC’s Fourth Assessment Report reveals that global warming is accelerating, at times far beyond projections outlined in earlier studies, including the latest IPCC Report. New modelling studies are providing updated and more detailed indications of the impacts of continued warming.
The emerging evidence is that important aspects of climate change seem to have been underestimated and the impacts are being felt sooner. For example, early signs of change suggest that the less than 1°C of global warming that the world has experienced to date may have already triggered the first tipping point of the Earth’s climate system – a seasonally ice-free Arctic Ocean. This process could open the gates to rapid and abrupt climate change, rather than the gradual changes that have been projected so far.

Humans and Nature Duel Over the Next Decade’s Climate
-
Rising greenhouse gases are changing global climate, but during the next few decades natural climate variations will have a say as well, so researchers are scrambling to factor them in.
