Abstract

Abstract:The hyporheic zone is an important ecotone occupying the interface between surface and ground water bodies, providing a range of important ecosystem services such as biochemical cycling, temperature regulation and downstream flood attenuation. Despite its importance in freshwater ecosystems in terms of services provided, the hyporheic zone has often been overlooked as a research topic. This study assessed the impact of cattle access to headwater streams on hyporheic zone parameters. The results indicate increases in levels of interstitial, hyporheic fine sediment downstream of cattle access points and the potential for this to negatively affect hyporheic invertebrate communities. Invertebrate community composition changes were observed at some sites with changes representing a shift to less diverse communities of smaller bodied invertebrates. The results presented here should help inform water resources managers and encourage them to consider the hyporheic zone as a part of an integrated freshwater ecosystem.

牛进入水源对潜流带的影响

摘要潜流带是地表水与地下水交界的重要过渡带，具有生物化学循环、温度调节和下游洪水衰减等重要生态系统服务功能。尽管潜流带在淡水生态系统中提供了重要的服务，但作为一个研究课题，它往往被忽视。本研究评估了牛入源对潜流带参数的影响。结果表明，在牛群接入点下游的间隙性、下隐细沉积物水平增加，并可能对下隐无脊椎动物群落产生负面影响。在一些地点观察到无脊椎动物群落组成的变化，这种变化代表着向较小的无脊椎动物群落多样性的转变。这里提出的结果应该有助于为水资源管理者提供信息，并鼓励他们将潜流带视为综合淡水生态系统的一部分。

期刊介绍： The journal aims to offer a broad coverage of the subject area, including the following: - biology and ecology of the Irish flora and fauna - microbial ecology - animal, plant and environmental physiology - global change - palaeoecology and palaeoclimatology - population biology; conservation of genetic resources - pollution and environmental quality; ecotoxicology - environmental management - hydrology - land use, agriculture, soils and environment. Submissions on other relevant topics are also welcome, and papers of a cross-disciplinary nature are particularly encouraged.
