South America stygobiont crustaceans: a new species of Hyalellidae (Amphipoda) and new reports of Stygocarididae (Anaspidacea) and Protojaniridae (Isopoda) from Calingasta Valley, Pre-Andean region, San Juan, Argentina.

Zootaxa, 2023
We describe one new eyeless Hyalella species, H. cuyana n. sp., from the hyporheic zone of Calingasta River, San Juan Province, Argentina. Hyalella cuyana n. sp.

Some remarkable distribution patterns in stygobiont Amphipoda

Journal of Natural History, 1993
Vicariant distribution patterns in stygobiont amphipod genera can be explained by plate tectonic effects (opening of the Atlantic) and by Tethyan events. Consequently these must be ‘old’ genera. Many stygobionts have congeneric relatives in shallow marine waters.

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 ...

Anchialine cave-dwelling sponge fauna (Porifera) from La Quebrada, Mexico, with the description of the first Mexican stygobiont sponges.

Zootaxa, 2020
Porifera has been relatively well studied from underwater caves worldwide. However, sponges in Mexico are only known from two anchialine caves: La Quebrada and El Aerolito, both in Cozumel Island.

The Moroccan stygobiont genus Heideella (Gastropoda, Prosobranchia: Hydrobiidae)

1999
The 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 ...

Metabolic rates of stygobiontic invertebrates from the Túnel de la Atlántida, Lanzarote

Marine Biodiversity, 2009
Numerous 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.

Differing trophic niches of three French stygobionts and their implications for conservation of endemic stygofauna

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 ...

Gelyelloida, a new order of stygobiont copepods from European karstic systems

Hydrobiologia, 1988
A 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 ...
