Global warming is causing the climate to change, lakes to dry up and less rain to fall. In population ecology, researchers have found that climate change plays an important role in controlling the size of species populations. To proof this model long-term observational data are crucial, making researchers to turn to historical records of locust outbreaks.  相似文献

Faced with imminent floods, what should decision-makers do first: evacuate the population, reinforce or intentionally break dikes? A support decision system developed by an international team of researchers will help them to make appropriate decisions to limit flood damage.From early 2000 to late 2002, CAS researchers from the Institute of Automation, the Institute of Remote Sensing Applications and the Institute of Atmospheric Physics teamed up with Chinese and European colleagues in conducting a three-year project  相似文献

Opioid analgesics such as morphine are the most powerful and widely-used drugs to relieve pain in clinical treatment. They largely work through the μ-opioid receptors in the central nervous system, alleviating the perception of pain. But repeated application of the drugs within a certain period of time could lead to side-effects, like addiction and tolerance. In order to develop new effective painkillers with less side-effects, researchers strive to have a deeper understanding of the mechanism responsible for the analgesic efficacy of the drugs and the formation of their adverse effects.  相似文献

The temperature of the upper reaches of the Yellow River, the second longest river in China,is clearly related to the worldwide warming trend, according to a study conducted by CAS researchers and their colleagues from Administration of Hydrology and Water Resources of the Upper Reaches of the Yellow River. They warn that, due to the possible temperature hike and drastic decline in local precipitation, the runoff in the reaches may face a trend of continued decrease over the next decade.  相似文献
