“…This relationship between water quality and richness of stygofauna has already been shown in the case of organic (Ait Boughrous et al, 2007) or inorganic e.g. (El Adnani et al, 2006;El Adnani et al, 2007) pollution. These studies have frequently highlighted a relationship between the effect of pollution from land application of wastewater (Ait Boughrous et al, 2007;Capasso, R, 1995) or the infiltration of leachate (El Adnani et al, 2006) and the sensitivity of the subterranean fauna.…”

The groundwater in the plain of Fez-Meknes constitutes a major resource in the region. The study highlights the importance of this resource, especially its irreplaceability. However, a number of inferences of point source pollution or diffuse were made. In this context, this study aimed at showing the possible relationships between the water quality of wells and springs and the diversity of the aquatic fauna which occurs in these habitats. To this end, the water quality and the fauna were regularly investigated in several stations (8 wells and 2 springs) selected in the region. The stations were chosen considering visible differences related to both their fauna and also some evident characteristics i.e. water table depth, nature of geological substratum, protection and human use, so that it was possible to expect certain diversity. The total faunal richness of stations was poorly correlated with water quality but, in contrast, the specific richness of the stygobiontic fauna (the subterranean species living in groundwater), and moreover the abundance of these stygobiontic species decreased significantly in case of water pollution. Thus the stygobiontic fauna and especially the peracarid crustaceans appear to be good indicators of water quality in the studied wells and springs.

“…Hyporheic animals seem to be less sensitive than their epigean relatives, at least for groups such as typical hyporheic isopods and amphipods (Plénet & Gibert, 1994;Plénet, 1995;Plénet et al, 1996;Plénet, 1999;Williams & Fulthorpe, 2003). However, more recently, El Adnani et al (2007) found that hyporheic fauna may show both qualitative and quantitative changes downstream from metal sulfide tailings containing Pb, Zn and Cu (see also Pyle & Mirza, 2007).…”

Spatial distribution patterns of the hyporheic invertebrate communities in a polluted river in Romania

The purpose of this study was to examine the sensitivity, in a field situation, of the hyporheic fauna to pollution by heavy metals and also to test the use of oxidative stress enzymes produced by this fauna as a sensitive indicator of oxidative stress generated by chemical contamination. This was done by surveying the patterns of distribution, structure, and composition of hyporheic invertebrate communities in one of the most polluted rivers in Romania. Twelve permanent sampling stations with differing water qualities were established along a 180 km transect of the Arieş River. Data on hyporheic invertebrate abundance and richness, chemistry of the surface and hyporheic water and interstitial suspended particles were analyzed via multifactorial analyses. In the downstream, more polluted stations, epigean species were less abundant and hyporheic communities, especially macrocrustaceans and oligochetes, became dominant. The higher levels of hyporheic invertebrate biodiversity in the moderately polluted stations compared to highly polluted, and the increase of the number of some hyporheos (especially macrocrustaceans) in the moderately polluted stations, suggested that the hyporheic fauna was more tolerant of heavy metal pollution than the surface water fauna of the area. However, the different richness and abundance of hyporheic fauna in sites of similar water chemistry suggested that additional factors, such as sediment structure are shaping the spatial distribution of hyporheic fauna. Strong correlations between superoxide dismutase (SOD) activity in pooled tissues extracts and some chemical parameters suggest that oxidative stress enzymes may prove to be sensitive indicators of chemical pollution in hyporheic zones.

“…More detailed evaluation of the reviewed studies revealed that 70% of studies in Africa concentrated on the description of newly discovered groundwater fauna (Figure 7a). Nevertheless, more than a dozen of studies in Algeria and Morocco conducted eco‐toxicological investigations, revealing that faunal richness in some urban and mining areas is linked with groundwater quality and stygofauna abundance decreases with pollution (Aidaoui, 2019; Boughrous, 2007; Boughrous et al, 2007; Boulaassafer et al, 2021; Boulal et al, 2017; Boutin et al, 1995; Boutin & Idbennacer, 1989; El Adnani et al, 2006, 2007; el Moustaine et al, 2013, 2014; Hallam et al, 2008; Hichem et al, 2019; Laid & Zouheir, 2018; Merzoug et al, 2011, 2014; Ramzi et al, 2020) with authors proposing the use of stygofauna as bioindicators of water quality (Merzoug et al, 2011, 2014). Boulaassafer et al (2021) study on evolutionary processes considerably expanded the knowledge of diversity and geographic range of a freshwater snail genus, and information on endemism and biogeographical distribution of stygobiotic crustacean species of Africa and Madagascar has been recorded (Tuekam Kayo et al, 2012).…”

Groundwater is an important global resource, providing water for irrigation, industry, geothermal uses and potable water. Moreover, groundwater contains the world's largest terrestrial freshwater biome with ecosystems, inhabited mainly by invertebrates (stygofauna) and microbes, undertaking important services including water purification, as well as nutrient and carbon cycling. Despite investigations on the spatial and temporal variations of groundwater fauna and the influence of environmental parameters on these organisms, in parts of the world, even the most basic knowledge of these ecosystems is still lacking. The aims of this study are to provide an overview on groundwater fauna (stygofauna) research, including the historical evolution of research topics and the development of sampling methods and secondly to identify the global distribution of groundwater fauna research and resulting data gaps. To achieve this, an extensive review of accessible groundwater fauna data was conducted by analysing 859 studies. It was evident that over time, there has been an exponential increase in the number of groundwater fauna studies together with changing paradigms in the research focus, particularly as sampling methods have developed from using simple nets, substrate samples and hand‐pumps in the beginning to recent molecular analyses (e.g. eDNA). As application of molecular methods becomes more common, knowledge on groundwater diversity and functional ecology is expected to increase. Studies on groundwater fauna are spatially uneven and are dominated by research in Europe and Australia, with few studies in Africa, Asia and the Americas. This presently biased view on groundwater biota hinders the identification of biodiversity patterns and ecosystem functions on a wider geographic and climatic scale. In the future, a more evenly distributed stygofauna sampling effort in currently underrepresented areas of the globe is necessary to ensure a more comprehensive perspective on stygofauna biodiversity, roles and functional significances. This is increasingly important with the accumulating knowledge of the sensitivities of these ecosystems to anthropogenic activities, including climate change, and is fundamental to effective management of these ecosystems.
