Studies on subterranean drift of stygobiont Crustaceans (Niphargus, Crangonyx, Graeteriella)
International Journal of Speleology, 1976 Summary In two groundwater canals of a water work in West Germany the drift of stygobiont groundwater organisms was investigated. The collections were made at two-hour intervals. Niphargus aquilex Schiödte, Crangonyx subterraneus Bate and Graeteriella unisetigera (Graeter) were considered more closely, because they were caught in greater numbers than ...

Back from the underworld: the exploitation of spring habitats by stygobiont species
HydrobiologiaAbstractStygobionts, namely animals with strong adaptations to subterranean environments that are unable to complete their life cycles outside groundwater, can be observed in spring ecotones, but their occurrence is generally considered accidental.

Zootaxa, 2021
A taxonomic revision of the stygobiont microsnails from north-western Transcaucasia (Krasnodar Krai, Russia) is presented. Two new genera—Schapsugia gen. n. and Tachira gen. n. are established. It is shown that the genus Paladilhiopsis does not occur in this area, and the snails previously assigned to this genus belong to Schapsugia gen. n. Two nominal

Gelyelloida, a new order of stygobiont copepods from European karstic systems
Hydrobiologia, 1988A new order, Gelyelloida, is proposed for Gelyella Rouch & Lescher-Moutoue, 1977 (ex Harpacticoida), an enigmatic genus of freshwater-inhabiting copepod from European karstic systems. The new order is characterized by a unique combination of generalised gnathostomous mouth parts and unusual derived features, some of them suggesting a possible neotenic ...

The Moroccan stygobiont genus Heideella (Gastropoda, Prosobranchia: Hydrobiidae)
1999The new genus Atebbania is described for a new hydrobiid species, A. bernasconii, which lives in groundwaters of southern Morocco. Of the Hydrobiidae genera with known shell and anatomy Moitessieria is the closest to Atebbania. The two share the following characters: shell elongate; teleoconch surface with evident microsculpture; seminal receptacle ...

A new stygobiont species of the genus Hadziella Kuščer, 1932 (Gastropoda: Hydrobiidae) from Spain
2023A new species of the genus Hadziella is described for Spain, which can be distinguished from other species in the genus by its particular morphology and a much smaller size. This is the smallest freshwater gastropod known so far for the Iberian Peninsula.

Aquatic Conservation: Marine and Freshwater Ecosystems, 2019
Abstract Groundwater ecosystems represent the greatest proportion of unfrozen freshwater on Earth and harbour high numbers of rare taxa with restricted distributions. Stygofaunal abundance, species richness, and ecology play essential roles in groundwater ecosystem services and functioning, as well as providing an important contribution to global ...

Metabolic rates of stygobiontic invertebrates from the Túnel de la Atlántida, Lanzarote
Marine Biodiversity, 2009Numerous studies have shown that hypogean organisms have a reduced metabolism when compared with their epigean counterparts. Although the cause of this metabolic cave adaptation is still uncertain, a current theory holds that it results from a reduced oxygen environment.
