由于最近一次报告的数据是在1980年之前，因此对南部的类似曲海鲈进行新的清查具有很大的生态学意义，包括在Mauricie地区的两条湖泊出口溪流中进行详尽的抽样。为了确定物种分布如何随着气候和环境变化而变化，需要经常取样。本研究共收集了65种曲霉属植物中的22种。收集到一种新的曲霉属植物（Prosimulium magnum complex），并发现了一些新的分布区域。详尽的抽样清楚地显示了单伏龙种和多伏龙种的时空分布变化。两个样地的物种季节出现是同步的，但Lac du Barrage的代数比Lac Souris的少。物种的定殖过程似乎是由环境决定的，河流宽度和基质类型的影响，如Simulium annulus， S. jenningsi。S. pictipes和S. innoxium在高流速的瀑布中被发现。在此研究之前，金黄色葡萄球菌在城市周边环境中的人工定植尚未在拟生物中观察到，这与许多蚊子种类不同。
Abstract There is great ecological interest in carrying out a new inventory of southern Québec simuliids, including an exhaustive sampling in two lake outlet streams of the Mauricie region, because data from Québec were last reported only prior to 1980. Frequent sampling is needed to determine how species distributions change in response to climatic and environmental changes. Twenty-two of the 65 Québec species were collected in the present study. One new species for Québec was collected (Prosimulium magnum complex), and new distribution areas were found for some species. Exhaustive sampling clearly showed time- and space-related distribution variations of the univoltine and polyvoltine species. Seasonal appearance of species was synchronized at the two sites studied, but generation number was smaller at Lac du Barrage than at Lac Souris. The species-colonizing process seems to be environmentally determined stream-width and substrate-type influenced, as Simulium annulus, S. jenningsi. S. pictipes, and S. innoxium, were found in high-current-velocity falls. Artificial site colonization by S. aureum in a peri-urban environment had not been observed among simuliids prior to this study, in contrast to many mosquito species.
