Article keywords: Coleoptera, Leiodidae, Pholeuon, Apuseni Mountains, systematics
Article: Dans cette septième et dernière étude régionale faisant partie de la révision systématique que nous avons initiée treize ans auparavant, on a disposé de neuf échantillons faunistique totalisant 1.297 individus (579 mâles et 718 femelles). Les résultats fournis par le traitement statistique des données biométriques montrent, dans ce cas de manière encore plus nette que d’habitude, qu’une différenciation des taxons infra-spécifiques n’est pratiquement possible qu’en tenant compte non seulement de la similitude morphologique, mais aussi du facteur biogéographique

Fauna of Oribatid mites (Acari, Oribatida) from the Movile Cave area (Dobrogea, Romania)
OTILIA IVAN, NICULAI ALEXANDRU VASILIU
Article keywords: Fauna, oribatid mites, Movile Cave
Article:The paper discusses the results of the investigations performed on the oribatid fauna collected from the Movile Cave area. 35 species, belonging to 25 genera and 17 families have been identified; among them 2 genera and 6 species are new for the Romanian fauna.

Article keywords: MSS, Mesovoid Shallow Substratum / superficial subterranean environment, sampling methodology, Araneae, Coleoptera, Collembola, Diplopoda, Oniscidea, Carpatho-Euxinic area, characteristic species, zoogeography
Article: Between 1998 and 2008, the authors analyzed from a faunistic and zoogeographic point of view, 5 sites with different types of mesovoid shallow subtratum (MSS) from the karst areas of Dobrogea and the Carpathians. These sites are: the cleitric MSS from the Movile area (South Dobrogea) – from the karst of Dobrogea and the nude and covered colluvial MSS from the Vârghişului Gorges (600–660 m.), the colluvial and cleitric MSS from the Motru Basin (370–407 m.), the nude (Marele Grohotiş – 1650 m., Cerdacul Stanciului 1571 m.) and covered colluvial (Valea Seacă – 1000m.) MSS from Piatra Craiului – from the karst areas of the Carpathians

Improphantes improbulus (Simon, 1929) (Araneae, Linyphiidae) new record for the Roumanian fauna
AUGUSTIN NAE
Article keywords: Improphantes improbulus, new record, cave, Piatra Craiului Mountains, Romania
Article: In this paper Improphantes improbulus (Simon, 1929) is presented for the first time in the literature about the Roumanian fauna. The new illustrations contribute to a better knowledge about morphological characterization of the species. The currently known distribution of this species in Roumania is also given

First records and rare species of Collembola in the Roumanian Fauna – The Piatra Craiului Massif (The Carpathians)
IONUŢ POPA
Article keywords: Mesovoid Shallow Substratum, Collembola, Piatra Craiului Massif, Romania, first records
Article: The author presents new data about the collembolan species collected from the Piatra Craiului Massif. Sixty-five species were identified from the material sampled from soil and mesovoid shallow substratum (M.S.S.) Three species (Arrhopalites ornatus Stach, 1945, Microgastrura duodecimoculata Stach, 1922 and Xenylla mucronata Axelson, 1903) are for the first time recorded in the Romanian fauna

The taxonomic and physiologic diversity of the acidophilic bacteria of the genus Thiobacillus used in ores solubilization processes
CARMEN MĂDĂLINA CIŞMAŞIU
Article keywords: Chemolithotrophic bacteria, metallic ions, resistance, Acidithiobacillus genus, biosolubilization, ores
Article: The development of biotechnological processes, based mainly on the activity of the acidophilic chemolithotrophic, proved their efficiency in recovering metals from sulphides ores and mining drains and in bioremediation of the polluted environment with residual inorganic substances, like the heavy metals ions and their compounds

The transfer of certain contaminants by means of surface and underground water-flows in the catchement area of Arieş stream, Romania
CONSTANTIN MARIN, IOAN POVARĂ, ALIN TUDORACHE, GÉZA RAJKA, MIHAI TERENTE
Article keywords: Suspended particulate matter, heavy metals, nutrients, mining area, hyporheic zone, Arieş
Article: Within an area heavily concerned by mining activities, chemical analyses have been performed in order to estimate the quality of the surface water and of the groundwater, by assessing also the concentrations of Ba, Mn, Fe, Cu, Zn, Ni, Cr, Cd, Al, Pb, Sb, As adsorbed on the surface of the suspended particulate matter (SPM). The investigations have addressed a 108 km long section of Arieş stream

Mineralogical analyses in various caves from the Băile Herculane area, the Cerna Passage
GABRIEL DIACONU, DELIA-GEORGETA DUMITRAŞ, ŞTEFAN MARINCEA
Article keywords: Endokarst, spelean mineralogy
Article: In this paper we present the results from the mineralogical analyses performed on samples from three caves in the Băile Herculane area. All minerals are recorded for the first time in the investigated caves. This cavity, lays at the base of the first morphological level of the Malm-Neocomian limestone, developed in the mount of the Ciorici Peak, on the right slope of the Cerna Passage (under the Elisabeta Peak) which is lined with the Roman Hotel from the Băile Herculane balneal spa

Geological and ecological assessment of the exposure degree of the Zăton-Bulba karst system (Mehedinţi Plateau) to the anthropogenetic hazards: intrinsic vulnerability and biodiveresity study
MARIUS VLAICU, CRISTIAN-MIHAI MUNTEANU, ANDREI GIURGINCA, CRISTIAN GORAN, CONSTANTIN MARIN, RODICA PLĂIAŞU, RALUCA-IOANA BĂNCILĂ, ALIN TUDORACHE
Article keywords: Intrinsic vulnerability, EPIK, karst groundwater, Opiliones, Mehedinti Plateau, karst, Zaton-Bulba
Article: The Mehedinţi Plateau represents an area highly marked by the intensity of the karst processes and by the diversity of the exokarst and endokarst features. The analyzed area includes two parallel limestone bars, developed on the Carpathian structures direction (NNE-SSW). In addition to the results obtained following the EPIK method protocol, we bring forward data concerning the water quality, performing hydrogeochemical analyses on water samples collected from the main sources in the region

Geological and hydrogeological research, tools for karst management in the north of the Caraş Gorges (Banat Mountains, Romania)
CRISTIAN-MIHAI MUNTEANU, MARIUS VLAICU, CONSTANTIN MARIN, ALIN TUDORACHE
Article keywords: Intrinsic vulnerability, EPIK, GIS, karst groundwater management, Banat Mountains
Article: The karst geosystems functioning frequently implies very quick mass and energy transfers, which make them highly sensitive to any natural or anthropogenic disturbance. Therefore, the groundwater resources, threatened by agricultural and industrial pollution, should be carefully exploited, taking into account the intrinsic vulnerability of the region

New report of Sorex alpinus Schinz, 1837 (Mammalia: Insectivora) from the Piatra Craiului Mountains (Romania)
IOANA NAE
Article keywords: Sorex alpinus, Piatra Craiului, caves, drilling, scree, MSS
Article: The distribution of the alpine shrew in Romania has a lot of gaps because of the small sized populations that remained in the alpine regions and their dynamics. Acording to literature, Sorex alpinus is present in small populations in the Eastern and Southern Carpathians. This faunal note contributes to a better understanding of local distribution and habitat preferences of populations of Sorex alpinus from the Romanian Carpathians

First record of Orchesella pannonica Stach, 1960 (Hexapoda, Collembola) in Romania
IONUŢ POPA
Article keywords: Collembola, Orchesella pannonica, first record, Runcu-Grosi Natural Reserve, Romania
Article: The author presents the first record of the springtail Orchesella pannonica (Hexapoda: Collembola) in the Romanian fauna. Notes on the taxonomic status, distribution and ecology of the species are given. Collembolans represent a major component of terrestrial ecosystems (and particularly significant members of the soil communities), constituting a significant proportion of the animal biomass and are thus frequently and easily found (BELLINGER et al., 1996–2009)
