Captive breeding of wildlife resources-China's revised supply-side approach to conservation.

The conservation and utilization of wild animals in China often raises public concerns. Thus, the Chinese government is increasingly exploring sustainable development of wildlife resources, and has implemented a series of measures, such as the modification of the Wildlife Protection Law (WPL), implementation of captive breeding licenses, an animal marking system, forest certification, and other actions to regulate captive breeding and utilization of wildlife. At the same time, the government tries to meet the Chinese traditional demand for wildlife products.

The impacts of climate changes and human activities on net primary productivity vary across an ecotone zone in Northwest China.

The variations in net primary productivity (NPP) and its controls are critical to understand the mechanisms that maintain ecosystem services under ongoing climate change and human activities. However, such knowledge is still incomplete in ecotone areas where plant species may reach their physiological thresholds. Our study quantified the variations in NPP and its controls resulting from interannual climate variations and human activities in the Qilian Mountain region (QLMR), an ecotone zone in central Asia.
