Distribution Map of Caves and Cave Animals in the United States, 1999, Culver, D. C. , Hobbsiii, H. H. , Christman, M. C. , Master, L. L.
The distributions of nearly 45,000 caves and 924 obligate cave species and subspecies (stygobites and troglobites) in the 48 contiguous states of the United States were mapped by county. Both maps show a highly clumped distribution. Approximately one-half of the variance in the number of species in a county is explained by variance in the number of caves per county.

Hotspots of Subterranean Biodiversity in Caves and Wells, 2000, Culver, D. C. , Sket, B.
We documented 18 caves and two karst wells that have 20 or more stygobites and troglobites. Crustacea dominated the aquatic fauna. Taxonomic composition of the terrestrial fauna varied, but Arachnida and Insecta together usually dominated. Geographically, the sites were concentrated in the Dinaric Karst (6 caves). Sites tended to have high primary productivity or rich organic input from the surface, be large caves, or have permanent groundwater (phreatic water). Dokumentirala sva 18 jam in dva kraka vodnjaka, iz katerih je znanih 20 ali vec vrst troglobiontov in stigobiontov. V vodni favni preladujejo raki. Taksonomski sestav kopenske favne je raznolik, vendar pajkovci in zuzelke skupaj navadno prevladujejo. Najvec taknih jam (est) je v Dinarskem krasu. Nadpovprecno so zastopane jame z lastno primarno produkcijo ali bogatim vnosom hrane s povrja, obsezne jame in jame, ki vkljucujejo tudi freatsko plast.

Les mollusques souterrains du rseau karstique de Padirac (Lot, France) et micro-rpartition de Bythinella padiraci Locard, 1903 (Mollusca, Caenogastropoda, Rissooidea), 2004, Bichain Jeanmichel, Boudsocq Christian, Pri Vincent
Subterranean molluscs of the karstic network of Padirac (France, Lot) and micro-distribution of Bythinella padiraci Locard, 1903 (Mollusca, Caenogastropoda, Rissooidea) - During a Padirac expedition in November 2003, about ten biological samplings were carried out in the deep karstic network. The first aim of this biospeological mission was to update the data on stygobites molluscs in this subterranean ecosystem. The results show that Bythinella padiraci Locard, 1903, species listed as vulnerable in the 2004 IUCN world Red List of threatened animals, although absent in the upstream part of the Padirac subterranean river, is present in its downstream part after the Dversoir and in the De Joly affluent. An hydrobioid belonging to the genus Islamia was recorded as a component of the stygobiontic biocenose of Padirac as well as Moitessieria rolandiana Bourguignat, 1863. In addition, 3 epigean freshwaters molluscs were observed alive in the deep network, Potamopyrgus antipodarum, Ancylus fluviatilis, Pisidium sp. as well as a terrestrial mollusc, Discus rotundatus.

Sensitive ecological areas and species inventory of Actun Chapat Cave, Vaca Plateau, Belize., 2005, Wynne J. J. , Pleytez W.
Cave ecosystems are considered one of the most poorly studied and fragile systems on Earth. Belize caves are no exception. This paper represents the first effort to synthesize information on both invertebrate and vertebrate observations from a Belize cave. Based on limited field research and a review of literature, we identified two ecologically sensitive areas, and developed a species inventory list containing 41 vertebrate and invertebrate morphospecies in Actun Chapat, Vaca Plateau, west-central Belize. Actun Chapat contains two ecologically sensitive areas: (1) a large multiple species bat roost, and (2) a subterranean pool containing troglobites and stygobites. The inventory list is a product of sporadic research conducted between 1973 and 2001. Ecological research in this cave system remains incomplete. An intensive systematic ecological survey of Actun Chapat with data collection over multiple seasons using a suite of survey techniques will provide a more complete inventory list. To minimize human disturbance to the ecologically sensitive areas, associated with ecotourism, we recommend limited to no access in the areas identified as sensitive.

Aquifers: the ultimate groundwater-dependent ecosystems, 2006, Humphreys W. F. ,
Australian aquifers support diverse metazoan faunas comprising obligate groundwater inhabitants, largely crustaceans but also including insects, worms, gastropods, mites and fish. They typically comprise short-range endemics, often of relictual lineages and sometimes widely vicariant from their closest relatives. They have been confined to subterranean environments from a range of geological eras and may contain information on the deep history of aquifers. Obligate groundwater fauna ( stygobites) occurs in the void spaces in karst, alluvial and fractured rock aquifers. They have convergent morphologies ( reduction or loss of eyes, pigment, enhanced nonoptic senses, vermiform body form) and depend on energy imported from the surface except in special cases of in situ chemoautotrophic energy fixation. In Australia, many stygofaunas in arid areas occur in brackish to saline waters, although they contain taxa from lineages generally restricted to freshwater systems. They may occur alongside species belonging to taxa considered typical of the marine littoral although far removed in space and time from marine influence. The ecological attributes of stygofauna makes them vulnerable to changes in habitat, which, combined with their taxonomic affinities, makes them a significant issue to biodiversity conservation. The interaction of vegetation and groundwater ecosystems is discussed and, in places, there are conservation issues common to both

Zoogeography and biodiversity of Missouri caves and karst, 2007, Elliott W. R.
The Missouri Cave Life Database contains 927 species and about 12,500 observation and collection records. About 1,038 (17%) of Missouris 6,200 caves and cave springs are biocaves with at least one species record, but only 491 sites (8%) have five or more species recorded. Missouri has 82 troglobites (67 described, 15 undescribed), including 49 aquatic and 33 terrestrial species. The aquatics include 30 described and six undescribed stygobites, plus 13 described phreatobites. The terrestrials include 24 described and nine undescribed species. Six of the troglobites (four described) may actually be troglophiles, edaphobites or neotroglobites. There are about 215 troglophiles (17 aquatic), 203 trogloxenes (20 aquatic) and 407 accidentals or of uncertain ecological classification (27 aquatic). Karst zoogeographic regions include the broad Springfield and Salem plateaus; the Boone, Hannibal, St. Louis, Jefferson-Ste. Genevieve, and Perryville karsts; and an isolated area, Caney Mountain. Troglobites are currently known from 728Missouri sites, including 597 caves (10% of known caves). Twenty-five troglobites, eight of which are new species, occur at single sites only. Missouri shares 48 troglobites with other states, exhibiting relatively low diversity in terrestrial troglobites compared to areas east of the Mississippi River, but high aquatic biodiversity. Values for species richness (SR), troglobites, site endemism (SE) and biodiversity (B) were derived to rank and compare caves for conservation planning. Many species and biologically important biocaves were added to the Missouri Natural Heritage Database and the Comprehensive Wildlife Conservation Strategy, a long-range, statewide conservation plan. Further work should focus on poorly known regions.
