Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

, 2016 渤海海峡跨海通道工程以鲁东大学为代表的众多专家已研究、论证20 余年。工程建设意向方案有三:利用庙岛群岛作为桥墩的桥梁方案、南桥北隧方案、全海底隧道方案。笔者上世纪80 年代参与过胶州湾青黄通道论证,关注过渤海海峡跨海通道工程,并有机会考察国内外多个大型跨海通道工程。根据积累的经验,将渤海海峡跨海通道与胶州湾青黄通道做一些对比,得出的基本认识:桥梁易受气象、海洋环境影响和战争破坏,不赞同这种方案;桥隧方案与桥梁方案一样,只不过桥的距离短一些;若工程上马的话,建设全程海底电气化铁路隧道为宜 ...

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We
