Abstract

Context

The Great Artesian Basin (GAB) feeds thousands of springs in Australia’s arid centre, supporting relictual species not found elsewhere on Earth. Springs are considerably threatened by ongoing water abstraction by industry. Robust management plans are needed to prevent further extirpations of GAB taxa, but fundamental biodiversity knowledge is lacking.

Aims

We aimed to characterise major organismal groups in South Australian GAB springs and surrounding wetlands, their conservation and taxonomic status, and potential biodiversity hotspots and connectivity of spring ecosystems.

Methods

Focusing on South Australia as a case study, we conducted a comprehensive review of GAB spring biota based on the published scientific and grey literature.

Key results

Almost 500 taxa have been recorded from GAB springs, the majority being invertebrates. Community composition is highly heterogeneous among spring clusters and the true extent of spring biodiversity is far greater than currently known.

Conclusions

GAB springs have intrinsic value as refugia for both endemics and cosmopolitan taxa. GAB invertebrates are poorly conserved and largely lacking in taxonomic knowledge. We highlight several potential biodiversity hotspots that have been overlooked in the literature.

Implications

Fundamental biodiversity information on the GAB is crucial for decision making in conservation management, for industry, and for Traditional Custodians.

南澳大利亚大阿特西亚盆地泉水和排放湿地生物群全面回顾

背景大自流盆地（GAB）为澳大利亚干旱地区中心的数千个泉眼提供水源，养育着地球上其他地方没有的孑遗物种。由于工业的持续取水，泉水受到严重威胁。需要制定强有力的管理计划来防止 GAB 分类群进一步灭绝，但目前还缺乏基本的生物多样性知识。目的我们旨在了解南澳大利亚 GAB 泉水及周边湿地的主要生物群体的特征、其保护和分类状况，以及潜在的生物多样性热点和泉水生态系统的连通性。方法我们以南澳大利亚州为案例，根据已发表的科学文献和灰色文献，对 GAB 泉水生物群进行了全面审查。主要结果GAB泉水中记录了近500个分类群，其中大部分是无脊椎动物。泉群之间的群落组成差异很大，泉水生物多样性的真实范围远远超过了目前已知的范围。结论GAB泉水作为本地物种和世界性类群的栖息地具有内在价值。人与生物圈无脊椎动物的保护程度很低，分类学知识也非常匮乏。我们强调了文献中忽略的几个潜在的生物多样性热点。意义全球生物圈保护区的基本生物多样性信息对于保护管理决策、工业和传统监护人都至关重要。

期刊介绍： Marine and Freshwater Research is an international and interdisciplinary journal publishing contributions on all aquatic environments. The journal’s content addresses broad conceptual questions and investigations about the ecology and management of aquatic environments. Environments range from groundwaters, wetlands and streams to estuaries, rocky shores, reefs and the open ocean. Subject areas include, but are not limited to: aquatic ecosystem processes, such as nutrient cycling; biology; ecology; biogeochemistry; biogeography and phylogeography; hydrology; limnology; oceanography; toxicology; conservation and management; and ecosystem services. Contributions that are interdisciplinary and of wide interest and consider the social-ecological and institutional issues associated with managing marine and freshwater ecosystems are welcomed. Marine and Freshwater Research is a valuable resource for researchers in industry and academia, resource managers, environmental consultants, students and amateurs who are interested in any aspect of the aquatic sciences. Marine and Freshwater Research is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
