Quantifying material flows mediated by parasites in lake

脊椎动物是水生态系统中最主要的寄生虫之一。我们应用分子技术和荧光染色技术研究了湖泊中卵裂藻的动态变化。在因巴湖，一年四季都会出现龟裂，感染硅藻等各种浮游植物。在湖泊中发现的各种真菌中，脊椎动物是优势物种。脊椎动物不仅作为浮游植物的寄生虫，而且还作为浮游动物的食物，在湖泊中调节物质流动。

Chytrids are one of the most dominant parasites in aquatic ecosystems. We investigated the dynamics of chytrids in lakes, by applying molecular techniques and fluorescence dying. In Lake inba, chytrids appeared throughout a year, infecting various phytoplankton species such as diatoms. Chytrids found to be dominant species among diverse fungi in lakes. Chytrids play important roles not only as parasites of phytoplankton but also as foods for zooplankton, mediating material flows in lakes.
