“…represent three different habitats on a small geographical, km, scale, each of them with specific fauna composition, not only within a single aquifer but also between aquifers in the same area at different depths. Site-specific fauna on a small scale was also observed in the karstic spring system of the River Pescara in the Abruzzi region (central Italy) (Stoch et al, 2016).…”

“…Work to date has documented the richness and distribution of groundwater species at distinct scales (from local to regional), allowing the characteristics of groundwater habitats commonly classified as porous, fissured, or karstic to be defined (Gibert, ; Gibert, Danielopol, & Stanford, ; Gutjahr, Schmidt, & Hahn, ; Stoch et al, ). However, the reliability of groundwater assemblages as biological markers is still unevenly explored at continental level.…”

Exploring the distribution of groundwater Crustacea (Copepoda and Ostracoda) to disentangle aquifer type features—A case study in the upper Tajo basin (Central Spain)

One of the most challenging questions in the assessment of groundwater ecosystem health is whether assemblages of groundwater biota can be used reliably as biomarkers. In this study, we aimed to (a) explore the diversity, distribution, and ecological composition of groundwater Crustacea, Copepoda, and Ostracoda communities from six aquifers in Central Spain and (b) relate the structure of the species assemblages to the aquifers' hydrogeological conditions, habitat features, and hydrochemistry. The datasets were simultaneously collected from 24 boreholes drilled in six unconfined aquifers from the upper part of the Tajo catchment. Our results show that the assemblages are primarily influenced by the specific hydrogeological conditions of the aquifer, determined by groundwater flow, supply of organic matter from the surface, and habitat features, whereas the aquifer's hydrochemistry has only a marginal effect. The assemblages from the Tertiary detrital aquifer were the most diverse, containing a mixture of stygobiont and nonstygobiont species distributed preferentially in the recharge area of the aquifer, characterized by medium hydraulic conductivity, high surface input and relatively high water renewal. The Quaternary alluvial aquifer type was found to have a moderate richness with several hyporheic dwellers, indicating an active surface/groundwater exchange with the adjacent stream channel.In contrast, the carbonate aquifer type was less diverse but markedly distinct owing to the high occurrence of stygobionts. Our results provide a step forward in exploring the groundwater biodiversity of aquifers in Spain and towards incorporating an ecological perspective into overall assessments of groundwater status.

“…Groundwater ecosystems are generally poorer in nutrients and oxygen than surface water ecosystems [12][13][14][15][36][37][38][39][40]. In order to reduce energetic costs, groundwater ectotherms have evolved metabolic rates that are lower than those of their close epigean relatives [20,[41][42][43][44].…”

Abstract:The average global temperature is predicted to increase by 3 • C by the end of this century due to human-induced climate change. The overall metabolism of the aquatic biota will be directly affected by rising temperatures and associated changes. Since thermal stability is a characteristic of groundwater ecosystems, global warming is expected to have a profound effect on the groundwater fauna. The prediction that stygobitic (obligate groundwater dweller) species are vulnerable to climate change includes assumptions about metabolic effects that can only be tested by comparisons across a thermal gradient. To this end, we investigated the effects of two different thermal regimes on the metabolism of the stygobitic copepod species Diacyclops belgicus (Kiefer, 1936). We measured the individual-based oxygen consumption of this species as a proxy of possible metabolic reactions to temperature rising from 14 to 17 • C. We used a sealed glass microplate equipped with planar oxygen sensor spots with optical isolation glued onto the bottom of 80-µL wells integrated with a 24-channel fluorescence-based respirometry system. The tests have provided controversial results according to which the D. belgicus populations should be prudently considered at risk under a global warming scenario.
