摘要

淡水系统中过量的细小沉积物（2 毫米的颗粒）的输送和沉积是影响水生生物群落和种群结构的一个重要因素。无脊椎动物的鳃表面可能会被细小沉积物覆盖，从而影响渗透调节功能。离子细胞是蜉蝣气管鳃上用于渗透调节的专门结构。在环境多变的条件下，为了维持渗透调节的需求，细胞的数量会发生变化。为了研究离子细胞是否会随细小沉积物压力的变化而变化，我们分别从英国两个细小沉积物覆盖率高和低的地方收集了蜉蝣个体。随后对气管鳃进行检查，以确定鳃上下表面的离子体数量，并根据鳃的大小进行标准化。结果表明，从细小沉积物覆盖率高的地区采集的蜉蝣的离子体数量明显较高。细沉积物多的地方海拔高度和溶解氧浓度也较低。从沉积物覆盖率高的地点采集的蜉蝣鳃也明显大于从沉积物覆盖率低的地点采集的蜉蝣鳃。这些结果表明，蜉蝣幼虫有可能对与细沉积物相关的压力表现出表型可塑性，但这些反应可能取决于细沉积物沉积物的成分（有机或矿物）以及相关的氧气浓度。

期刊介绍： Ecological Entomology publishes top-quality original research on the ecology of insects and related invertebrate taxa. Our aim is to publish papers that will be of considerable interest to the wide community of ecologists who are motivated by ecological or evolutionary theory. The suitability of a manuscript will usually be assessed within 5 days. We publish full-length Original Articles as well as Reviews, Short Communications, Methods and Natural History papers. In Original Articles, we greatly prefer papers that test specific hypotheses and which have a high degree of novelty. All categories aim for innovative contributions that advance the subject of ecological entomology.
