The Crustaceans of the reservoir of the Fontaine des Suisses at Dijon., 1966,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Dussart Bernard, Graf Franois, Husson Roger
Inventory of the Crustaceans collected in the basin of the Fonatine des Suisses at Dijon. The Copepoda are represented by 5 species: Macrocyclops albidits, Eucyclops serrulatus in two slightly different forms, Eucyclops serrulatus var. mihi, Acanthocyclops venustus, Acanthocyclops vernalis and Acanthocyclops robustus. The coexistence of these two last forms in this very tiny environment makes it probable that we have here to do with two distinct species. A determination key is given for the Genus Acanthocyclops. Amphipoda are represented by Niphargus virei and especially Niphargus kochianus kochianus of which more than 100 samples have been collected. Of this last small species some considerations regarding geography, the laying of eggs, sexual dimorphism and closely related species are also given.

Critical evaluation of recent work on the systematics of subterranean Crustacea (with description of two new genera of Parabathynellidae, Bathynellacea)., 1976,

This paper reviews critically some recent work on the systematics of subterranean Crustacea, in particular Jakobi's work on the Parastenocarididae (Copepoda), Serban's work on the Bathynellidae (Bathynellacea, Syncarida) and Schminke's revision of the Parabathynellidae (Bathynellacea, Syncarida). Is is pointed out that three different approaches have been adopted in each of the three cases and advantages and shortcomings of each of them are analysed. Finally descriptions are given of two new genera of Parabathynellidae, Afrobathynella gen. n. and Nunubathynella gen. n., from a locality near Port Elisabeth (South Africa).

Perspectives in the Study of the Zoogeography of Interstitial Crustacea: Rathynellacea (Syncarida) and Parastenocarididae (Copepoda)., 1981,

Schminke Horst Kurt
Aspects of the zoogeography of Bathynellacea and Parastenocarididae are discussed in the light of my recent investigations. Parastenocarididae in Australia are rare and not very diverse in number of species. Four species belonging to three genera were collected on a tour through Australia in 1968. Despite relationships to species from other Gondwanian landmasses the poorness of the Australian fauna, together with the apparent ability of this family to spread over longer distances, suggest a late arrival of Parastenocarididae in Australia. Invasion is likely to have taken place from two directions. As for the Bathynellacea, the relationships presumed to exist between genera from Australia and Malaysia within the Parabathynellidae have been invalidated. As an alternative to the double-armed dispersal model of the Parabathynellidae propounded earlier, a vicariance model is discussed following Schram (1977). The zoogeography of Parastenocarididae can probably be best explained in terms of a primary dispersal history.

Springs and wells in SW and S part of Cyprus were briefly surveyed. Chlorinity was 0.1; 0.8 p.p.t. Some isopods were found in collecting galleries of springs and in wells in calcarenites and in gravel deposits. These were Proasellus coxalis ssp. with some depigmented specimens, the probably stygobitic P. c. nanus ssp. n., poorly pigmented Jaera italica, and Microcharon luciae n. sp.; they were accompanied by the stygobitic amphipod Bogidiella cypria, by Turbellaria (Tricladida), by Copepoda (Cyclopoida), and rarely by some other animals (Pisidium sp., Oligochaeta). Only slightly depigmented Turbellaria Tricladida (cf. Dugesia sp.) occur in wells far from surface waters. Descriptions of new taxa are given.

Three new species of harpacticoid copepods are described and discussed. Nitocrella beatricis n. sp. has been collected in different hyporheic sites in Sardinia and in two caves (Bue Marino cave in Sardinia and St. Barthlmy cave in Corsica); Elaphoidella janas n. sp. and Parastenocaris triphyda n. sp. have been collected only in Bue Marino cave. Some considerations concerning the ecology and biogeography of the three species are also presented.

The genus Parastenocaris, new for Greece, has been discovered in the hyporheic habitat of Kos and Kythira Island with two new species, that are described and discussed in this work. Parastenocaris aesculapii n. sp. shares some characters with P. nolli from Germany and P. italica from Italy, Macedonia and Turkey. Parastenocaris aphroditis n. sp. belongs, according to the Authors, to a group of species living exclusively in estuarine interstitial habitats, which are all characterised by peculiar morphology and ecology, that are as well considered and interpreted.

Ratio of copepods (Crustacea: Copepoda) in fauna of percolation water in six karst caves in Slovenia, 2001,

Hypogean fauna from percolation water and from puddles, filled with percolation water from six cave systems in Slovenia, was studied in the period 2000/2001. Special attention was given to the ratio of copepods (Crustacea: Copepoda) to the other taxa in the samples. Four categories of small water-bodies were distinguished: direct water jets from the ceiling, permanent small depressions on stalagmites filled with water, puddles on clay and puddles on calcareous sinter. Faunal data are supplemented with other information, including geographical position of the caves, physical and chemical parameters of water quality, cave roof thickness, geological structure of the limestone strata, hydrology and vegetation above the caves.

Pipan, T.

The present contribution deals with aquatic fauna of the Pivka intermittent lakes. Due to their intermittent character some interesting crustaceans from the groups of fairy shrimps (Anostraca), water fleas (Cladocera) and copepods (Copepoda) are found there. Petelinjsko jezero is the only known location in the world for the endemic species Chirocephalus croaticus. Copepod species Diaptomus cyaneus and Diacyclops charon are relatively abundant in Europe, but Petelinjsko jezero and Veliko Drskovško jezero are the only two locations known in Slovenia for both species. All the species are threatened due to destruction of their natural habitats.

What Does the Distribution of Stygobiotic Copepoda (Crustacea) Tell Us About Their Age?, 2007,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Culver D. C. , Pipan T.

Geographic distribution of stygobionts is often used to estimate age of a group by assuming vicariant speciation with little or no subsequent dispersal. We investigated the utility of using distributional data for Slovenian stygobiotic copepods by assuming that dispersal is a way to measure age of a species. We list some species of Copepoda that, on the basis of their range and frequency of occupancy within their range, should be older. Body size is not predictor either of range or frequency of occupancy.

The copepod crustacean fauna collected from subterranean habitats, including caves, wells, and the hyporheos of streams in and near the Interior Low Plateaus of the United States is dominated by Cyclopoida, with 39 species, followed by Harpac­ticoida with 9, and Calanoida with 2. Nearly all of the harpac­ticoid and calanoid species are widespread, primarily surface-dwelling generalists. Fourteen of the cyclopoids, members of the genera Diacyclops, Itocyclops, Megacyclops, and Rheocyclops, are apparently obligate stygobionts or hyporheic. Several of the species that are more strongly modified for subterranean exis­tence occur only in the more southern, unglaciated areas. Our sampling data support the hypothesis that the more specialized, groundwater-interstitial species have been unable to disperse into previously glaciated regions; whereas some, less-special­ized species may have invaded groundwaters from surface habi­tats as the glaciers receded.

Biodiversity and ecology of fauna in percolating water from Slovenian and Romanian caves was studied. Research focused on unravelling the community structure of epikarst fauna, which is carried away by the trickles of percolating water from the epikarst and vadose zones. The major part of the fauna found in percolating water is represented by copepods. This fauna, originating in the epikarst, was analysed and by means of the systematic sampling and observation the same groups of animals were found in Slovenian and Romanian caves. Differences among caves and sampling points indicate that epikarst is a heterogenous habitat. Relationship between faunal richness and the physical characteristics of the water was found. Correlation between surface geomorphology and fauna in percolating water was statistically significant in the Postojna cave system.

Papi Federica, Pipan Tanja
Epikarst biodiversity in relation to environmental conditions was studied for the first time in an ice cave, Snena jama na planini Arto on Mt. Raduha in north central Slovenia. In this alpine cave five sampling sites were monitored for fauna in percolation water in the period of one year. Temperature, conductivity, discharge, pH, total hardness and concentrations of various ions (calcium, chloride, nitrite, sulphate and phosphate) of water were measured. At the entrance of the cave ice is present all year round and the temperature inside the cave rises to a maximum of 4°C. These circumstances are reflected in the fauna found in percolating water. The first sampling site in the permanent ice was without fauna, as did the sampling site in an area with moonmilk. In the other three sampling sites, individuals of ten invertebrate taxa were found, Copepoda being the most abundant. Their abundance was positively correlated with discharge, pH and temperature of percolation water and additionally in the most abundant drip also with conductivity and total hardness. High proportion of immature copepods in drips shows that epikarst is their primary (i.e. source) habitat. Investigations of the alpine epikarst fauna can help to understand better the ecology of the epikarst fauna and its roles within the large range of different shallow subterranean habitats.

The aim of the present study was to assess copepod species richness in groundwater habitats from the Pădurea Craiului Mountains, Transylvania (northwestern Romania). Five species richness estimators (one asymptotic, based on species accumulation curves, and four non-parametric) were compared by testing their performances in estimating copepod species richness at three hierarchical spatial scales: cave, hydrographic basin, and karstic massif. Both epigean and hypogean species were taken in account. Two data sets were used in computing copepod species richness: 1. samples collected continuously during one year (dripping water) and seven months (pools) from five caves, and 2. samples collected from pools in twelve additional caves (data gathered from literature). Differences in copepod species richness among caves and hydrographic basins suggest that local environmental features are important in determining local species richness trends.
