摘要含水层中的无脊椎动物生态学很少受到关注。本文分析了英国（英格兰、苏格兰和威尔士）的隐花蛇绿岩（专性地下水）动物群。审查这些生物的生态系统功能，其潜在的脆弱性，人为压力，包括水污染和提取，和研究的优先事项，将允许当前的地下水管理的挑战得到解决。在英国，stygobites主要局限于英格兰和威尔士。该组合包括甲壳类无脊椎动物（9种），与欧洲大陆相比非常有限。在大不列颠只有一种已知的特有物种，即Niphargus glenniei（在爱尔兰共和国还发现了另外两种特有甲壳类动物）。此外，在英国的流动沃茨的间隙栖息地中发现了一套水螨（18种）。Niphargus glenniei最近被列入联合王国生物多样性行动计划的优先物种名单。水硬骨鱼只存在于地下环境中，如含水层、泉水和河流的潜流区，对生物多样性做出了独特的贡献。我们的分析表明，冰川遗产和（水文）地质的性质是这些组合的分布的主要控制因素。大多数记录都来自德文斯冰期冰盖南部界限以南的地方。大多数stygobites也被发现在石灰质地层，虽然高碳酸钙浓度可能不是所有的甲壳类stygobites重要。记录主要来自白垩纪、石炭纪和侏罗纪石灰岩含水层以及其他强烈裂隙地层的样本。具有广泛裂隙的地层可能为地下水动物提供最大的栖息地。我们的调查显示，在英国，有stygobites记录的地点相对较少（513个地点的stygobites记录已被证实）。需要开展研究，以提高我们对地下水动物的基本生物学和生态学以及它们提供的生态系统服务范围的认识。还需要了解地下水动物对污染和抽取压力造成的压力的反应，并制定适当的监测、评估和保护标准。水框架指令要求对水体的化学、水资源和生态条件进行更综合的评估。Stygobites有可能在地下环境中充当哨兵，帮助我们了解这个很少考虑的栖息地的状况和生态健康。
AbstractThe invertebrate ecology of aquifers has received little attention. This paper presents an analysis of stygobite (obligate groundwater) fauna from Great Britain (England, Scotland and Wales). A review is presented of the ecosystem functions performed by these creatures, their potential vulnerability to anthropogenic stress including water pollution and abstraction, and research priorities that will allow current groundwater management challenges to be addressed. In Great Britain stygobites are largely restricted to England and Wales. The assemblage comprises crustacean invertebrates (nine species) and is very limited in comparison with continental Europe. There is only one known endemic species in Great Britain,Niphargus glenniei(a further two endemic crustaceans are also known from the Republic of Ireland). Additionally, a suite of water mites (18 species) is found in the interstitial habitats of running waters in Great Britain.Niphargus glennieiwas recently added to the United Kingdom Biodiversity Action Plan priority species list. Stygobites, which are found only in subterranean environments such as aquifers, springs and the hyporheic zone of rivers, make a unique contribution to biodiversity. Our analysis suggests that both the glacial legacy and the nature of the (hydro)geology are major controls on the distribution of these assemblages. Most records were from locations to the south of the southern limit of the ice sheet during the Devensian glaciation. The majority of stygobites were also found in calcareous strata, although high calcium carbonate concentrations may not be important to all crustacean stygobites. Records were dominated by samples from the Chalk, the Carboniferous and Jurassic Limestone aquifers, and from other strongly fissured strata. Strata with extensive fissuring may provide the greatest availability of habitat for groundwater fauna. Our investigation revealed that there are relatively few sites from which stygobites have been recorded in Great Britain (513 sites at which records of stygobites have been confirmed). Research is needed to improve our understanding of the basic biology and ecology of groundwater-dwelling fauna and the range of ecosystem services that they provide. An understanding of the response of groundwater fauna to stress caused by pollution and abstraction pressures is also needed, together with the development of appropriate monitoring, assessment and protection criteria. The Water Framework Directive requires a more integrated assessment of the chemical, water resources and ecological conditions of water bodies. Stygobites have the potential to act as sentinels in the subterranean environment and help inform us about the condition and ecological health of this little-considered habitat.
