鳞侧石鳖属(Leptochiton)一物种在西太平洋雅普海沟分布的新记录

蛟龙号载人潜水器在位于雅普海沟北部6 745 m深处的底栖沉积环境中采集到两只石鳖样本，这是石鳖物种分布于此的新记录。形态学和DNA分子标记均支持两只石鳖为鳞侧石鳖属（Leptochiton）同一物种。该种在形态上与L.vanbellei和L.deforgesi接近；在系统发生方面，与L.vanbellei，L.deforgesi和L.boucheti的亲缘关系密切。这是截至目前世界石鳖分布报道的第三深度记录。     

Physical and chemical limnology of six hydroelectric lakes on the Waikato River, 1970–72

The Waikato River flows from oligotrophic Lake Taupo through eight impoundments to the sea. As it does so, physicochemical changes occur; conductivity and dissolved oxygen levels decrease, patterns in the seasonal variation in pH and alkalinity change, and the nitrogen and phosphorus concentrations increase. Except for the changes in conductivity, changes in the other parameters are characteristic of eutrophication. This eutrophication is associated with an increase in the intensity of pastoral farming in the catchment of the Waikato River downstream of Lake Taupo.
