Abstract

Floods are normal components of many river regimes and, as such, they exert a significant influence at the ecosystem level. In recent decades, however, climate change has increased the frequency and intensity of floods, with serious consequences for lotic biota, particularly benthic macroinvertebrates, due to their limited mobility and sensitivity to disturbance. The impact of floods varies according to different biological parameters including the characteristics of the macrobenthic communities (taxonomic composition, morphology, behaviour, and life history traits) on one hand and various nonbiological parameters such as flood intensity, artificialisation of the river bed, the presence of dams, and many other factors on the other. Understanding these dynamics is pivotal to improve the effective management and conservation of aquatic ecosystems in the context of current climate change. The aim of this short communication is to evaluate the impact of a catastrophic flood on the macroinvertebrate community of a low-order Appennine stream (NW Italy). This will provide data regarding the varying impacts on different taxa and the recovery pattern of this significant component of the ecosystem.

灾难性洪水对低阶溪流中大型无脊椎动物群落的影响：亚平宁山脉（意大利西北部）研究

洪水是许多河流水系的正常组成部分，因此对生态系统具有重大影响。然而，近几十年来，气候变化增加了洪水的频率和强度，对地层生物群落，特别是底栖大型无脊椎动物造成了严重后果，因为它们的活动能力有限，对干扰很敏感。洪水的影响因不同的生物参数而异，这些参数一方面包括大型底栖生物群落的特征（分类组成、形态、行为和生活史特征），另一方面还包括各种非生物参数，如洪水强度、河床人工化、水坝的存在以及许多其他因素。在当前气候变化的背景下，了解这些动态对改善水生生态系统的有效管理和保护至关重要。这篇短文的目的是评估一场灾难性洪水对一条低阶亚平宁溪流（意大利西北部）大型无脊椎动物群落的影响。这将提供有关对不同类群的不同影响以及生态系统中这一重要组成部分的恢复模式的数据。

期刊介绍： Water (ISSN 2073-4441) is an international and cross-disciplinary scholarly journal covering all aspects of water including water science and technology, and the hydrology, ecology and management of water resources. It publishes regular research papers, critical reviews and short communications, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
