从大型无脊椎动物响应（持久性和恢复力）和食物网群落结构的角度研究和评价了山涧大洪水引起的变化。本研究是在Matarranya河上游（Parrizal和Vallderroures）进行的，2000年10月的暴雨造成了严重的破坏（三天内流量从0.2米/秒增加到450米/秒）。洪水过后，两个研究地点的密度下降了97%以上。几乎在所有情况下，碎屑都成为大型无脊椎动物的首选食物，硅藻是饮食的补充部分。
Changes due to a large flood in a mountain stream were investigated and evaluated from the perspective of macroinvertebrate responses (permanence and resilience) and food-web community structure. This study was conducted on the upper reaches of Matarranya Stream (Parrizal and Vallderroures), where heavy rainfalls in October 2000 caused severe damages (within three days the flow increased from 0.2 to 450m/s). After the flood, densities decreased of more than 97% in the two study sites. Nearly in all cases, detritus became the preferential food for the macroinvertebrates, with diatoms as a complementary part of the diet.
