落入溪流的枯叶是许多无脊椎动物的重要食物来源。如果它们首先被水生丝孢菌和其他微生物定殖，它们通常会变得更可口和更有营养。至少有两种机制似乎是负责这种调节作用：微生物生产（除了容易消化的微生物化合物的营养不良的叶基板），和微生物催化（转化为可消化的亚基的难消化的叶物质的微生物酶）。不同的无脊椎动物物种利用微生物调节的能力各不相同。这似乎是由他们的流动性，他们的食物资源的范围和他们的能力，克服防御机制的叶殖民微生物的影响。
Dead leaves falling into streams are an important food source for many invertebrates. They are generally made more palatable and more nutritious if they are first colonized by aquatic hyphomycetes and other micro-organisms. At least two mechanisms appear to be responsible for this conditioning effect: microbial production (addition of easily digested microbial compounds to the nutritionally poor leaf substrate), and microbial catalysis (conversion of indigestible leaf substances into digestible subunits by microbial enzymes). Different invertebrate species vary in their ability to take advantage of microbial conditioning. This appears to be influenced by their mobility, the range of their food resources and their ability to overcome defense mechanisms of leaf-colonizing microorganisms.
