在这项研究中，我们评估了当前的速度和粉碎机的存在，在人工渠道操纵，对真菌组合的结构殖民桤木（Alnus dumerosa（L.）Gaertner）叶在粗和细网袋中孵育。真菌产孢率，累计分生孢子产量和水生丝孢菌的物种数较高，而不是低流速暴露在叶片。观察到相反的辛普森指数（D）的真菌组合。一些种类的水生丝孢菌一致刺激高电流通道。未观察到粉碎机或筛网类型的影响。（© 2006 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆）
In this study we assessed the effect of current velocity and shredder presence, manipulated in artificial channels, on the structure of the fungal assemblage colonizing alder (Alnus glutinosa (L.) Gaertner) leaves incubated in coarse and fine mesh bags. Fungal sporulation rates, cumulative conidial production and number of species of aquatic hyphomycetes were higher in leaves exposed to high rather than to low current velocity. The opposite was observed regarding Simpson's index (D) on the fungal assemblage. Some species of aquatic hyphomycetes were consistently stimulated in high current channels. No effect of shredders or of mesh type was observed. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
