Révision systématique des Leptodirinae souterrains des Monts Apuseni. VII. Le sous-genre Pholeuon (s. str.) du bassin de Crişul Negru (Monts du Bihor)

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)

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. The taxonomic and zoogeographical spectrum of the fauna was analyzed, as well as the occurrence of the species depending on depth

Invertebrate communities from the mesovoid shallow substratum of the Carpatho-Euxinic area

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

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)

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

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

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

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

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)

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)

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

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)

A contribution to the history of biospeleology: unpublished notes and documents concerning the initiation of the Cuban-Romanian biospeleological expeditions to Cuba (1969, 1973)

The rediscovery by the first author of the three letters received by him from A. Núñez Jiménez – at that time president of the Academy of Sciences of Cuba – throws new light on the events having lead to the organisation of the first biospeleological expedition to Cuba, this being at the same time the first scientific expedition abroad made by Romanian naturalists from the post-war period
