EUGEN NITZU, IONUȚ POPA, AUGUSTIN NAE, CLAUDIU IUȘAN

Cuvinte cheie: The Rodnei Mountains, biosphere reserve, Araneae, Collembola, Orthoptera, Coleoptera, new faunal and zoogeographic data

Articol: The faunal lists of cave, epigaeic and soil species of Araneae (73 species), Collembola (61 species), Orthoptera (35 epigaeic species) and Coleoptera (127 species) collected in the years 2005 and 2006 from the Rodnei Mountains Biosphere Reservation are presented. Among these, eight species: Rugathodes bellicosus (Araneae, Theridiidae), Glyphesis servulus (Araneae, Linyphiidae), Incestophantes frigidus (Araneae, Linyphiidae), Gnaphosa badia (Araneae, Gnaphosidae), Eusphalerum pallens (Coleoptera, Staphylinidae), Cryptophagus corticinus (Coleoptera, Cryptophagidae), Otiorrhynchus scaber (Coleoptera, Curculionidae) Thamnurgus varipes (Coleoptera, Scolytidae) – are for the first time recorded for the Romanian fauna

Data concerning the Araneae fauna from the Aninei Mountains Karstic area (Banat, Romania)

AUGUSTIN NAE

Cuvinte cheie: Araneae, Aninei Mountains, MSS, Banat, Romania

Articol: The author presents data about the species of spiders collected from the Aninei Mountains karstic area. Among the 64 species identified from the material sampled from the edaphic and subterranean environments (caves and mesovoid shallow substratum), 21 species are new for the area. The chorological composition of the fauna is presented, followed by some statistical ecology analyses

Data on the Limanu cave mineralogy, South Dobrogea

GABRIEL DIACONU, ȘTEFAN MARINCEA, DELIA DUMITRAȘ

Cuvinte cheie: Cave minerals, Limanu Cave, Dobrogea de Sud

Articol: By means of diphractometric X-rays analyses on powders, we emphasize an association of minerals in the Limanu Cave from South Dobrogea, made up of hydroxylapatite, brushite, calcite, gypsum and dolomite as the main minerals and quartz and illite as secondary minerals

Karst groundwaters vulnerability assessment methods

MARIUS VLAICU, CRISTIAN-MIHAI MUNTEANU

Cuvinte cheie: Karst groundwaters, vulnerability, assessment methods

Articol: A major socio-economic and scientific issue is represented by karst hydrostructures vulnerability mapping, which qualitatively and quantitatively highlights their exposure degree. Two research trends have been developed, one taking into account the environment features exclusively – the aquifer and protective cover type, permeability, aquifer depth, recharge rate, etc. (intrinsic vulnerability), the other focused on the types and quantities of pollutants (specific vulnerability)
