Changes in surface land use may threaten groundwater quality and ecosystem integrity, particularly in shallow aquifers where links between groundwater and surface activities are most intimate. In this study we examine the response of groundwater ecosystem to agricultural land uses in the shallow alluvial aquifer of the Gwydir River valley, New South Wales, Australia. We compared groundwater quality and microbial and stygofauna assemblages among sites under irrigated cropping, non-irrigated…

An inter-catchment comparison of groundwater biota in the cotton-growing region of north-western New South Wales
Abstract. Groundwater is essential to crop production in many parts of the world, and the provision of clean groundwater is dependent on healthy groundwater ecosystems. To understand better the…
Habitat, water quality, seasonality, or site? Identifying environmental correlates of the distribution of groundwater biota
The distribution of biota in aquatic ecosystems, including aquifers, is collectively influenced by habitat structure, water quality, seasonality, and local variations in environmental conditions.…
Southern South Australian groundwater microbe diversity.
TLDR
Assessment of groundwater microbial communities from the populated part of the state indicates that despite overrepresentation of pollutant-associated bacterial orders in and around the Adelaide metropolitan area, microbial communities remain diverse and show little evidence of converging on a common pollutants-effected community.

The Study of Hydrogeochemical Environments and Microbial Communities along a Groundwater Salinity Gradient in the Pearl River Delta, China
The salinization of groundwater is an issue in coastal areas because it causes the deterioration of freshwater resources, significantly impacting human livelihoods and ecosystems. This study…
Bacterial communities at a groundwater-surface water ecotone: gradual change or abrupt transition points along a contamination gradient?
TLDR
The results emphasize the utility of bacterial communities in the assessment of groundwater-dependent ecosystems and call for a careful reconsideration of threshold nitrate values for defining groundwater ecosystem health and protecting their microbial biodiversity.
Different depths, different fauna: habitat influences on the distribution of groundwater invertebrates
At regional and catchment scales, geology and hydrogeology strongly influence the distribution of groundwater invertebrates (stygofauna), but the fine scale distribution of stygofauna in sedimentary…

Imperilled Subsurface Waters in Australia: Biodiversity, Threatening Processes and Conservation
Subsurface waters in Australia span massive aquifers to small cave streams and fluctuating hyporheic zones where stream water exchanges with groundwater. Groundwater resources have been exploited…
Do faunal assemblages reflect the exchange intensity in groundwater zones?
The exchange of water with groundwater is a key determinant of water quality and faunal assemblage. Water exchange not only occurs with running waters, but also through percolation, interception…
The potential use of fauna and bacteria as ecological indicators for the assessment of groundwater quality.
TLDR
The sensitivity of groundwater communities towards impacts from land use and surface waters is exemplarily demonstrated by a data set of two geologically similar but hydrologically partially separated aquifer systems, which show that there is legitimate hope for the application of ecological criteria for groundwater quality assessment in the future.
Biodiversity, functional roles and ecosystem services of groundwater invertebrates
TLDR
Examples from Australian and New Zealand alluvial aquifers reveal knowledge gaps in understanding the functional importance of most stygofauna, hampering effective protection of currently undervalued groundwater ecosystem services.
