However, this requires establishment of essential, ecosystem services on a planet currently unamenable Terran species. Shorter term, assembling Terran-type ecosystems within contained environments conceivable if mutually supportive species complement...
Nature reserves are widely considered as one available strategy for protecting biodiversity, which is threatened by habitat fragmentation, and wildlife extinction. The Chinese government has established a goal of protecting 15% of its land area by 2015. We quantitated the characteristics and distribution of nature reserves in mainland China and evaluated the expansion process for national natur...

Chinese nature reserves contain a rich diversity of plant species that are at risk of becoming more threatened by climate change. Hence, it is urgent to identify the extent to which future climate change may comp...
