IN MEMORIAM - Constantin “Costin” Rădulescu (1932–2002), Remembrances of a Dear Friend

Article keywords: In memoriam, Constantin Radulescu

Article: 20th century, beginning of the fifth decade. The generation of the 30s was finally graduating high school after a thorough baccalaureate examination and knocking at the gates of the Universities in search of their path in life. They had been through extremely difficult and painful times, filled with deprivations caused by World War II and followed by the terrible drought of 1947-49 and closely entwined with the fight for power of the few insurgents arriving on Soviet tanks in order to annihilate the democratic regime in Romania

New contributions to the microbiota naturally occurring in the Movile Cave

Article keywords: Subsurface microbiology, chemoautotrophic bacteria, sulfur-oxidizing bacteria, Movile cave ecosystem

Article: In September 2000, nearly 15 years after the Movile cave (Mangalia, Romania) was discovered and it was demonstrated that this ecosystem is entirely chemoautotrophically based-and thus able to sustain the energy requirements of all its components, a new campaign for sample. collection was: carried out. The sample collected were microbiologically and biochemically analysed using selective media for a large range, of physiological groups of chemoautotrophic and heterotrophic microorganisms

Airborne microorganisms in show caves from Romania

Article keywords: Airborne microorganisms, mesophilic bacteria, fungi, show caves

Article: Mesophilic bacteria and fungi were investigated in the air of three show caves in the Western Carpathians, Romania. The concentration of total aerobic viable bacteria, staphylococci, streptococci and Gram negative bacteria, and Candida spp. ‘was generally higher within the visited areas, after the tourists’ passage, than in the iriner part of the caves or outside. In contrast the dominant fungi Aspergillus, Penicillium and Mucor were found at higherconcentration outside the caves, their number decreasing from the entrance towards the interior of the cave

Contribution to the historical biogeography of the Oniscidean lineage Mesoniscus (Microcheta, Isopoda, Crustacea)

Article keywords: Mesoniscus, historic distribution, palaeobiogeography

Article: As Emile Racovitza pointed out in his classical Essai sur les-problémes biospéologiques: “...on ne pourra se livrer 4 1’étude chorologique des Cavernicoles pris en bloc; car les faunes et les flores souterraines sont des faunes et des flores dérivées, formées par une agglomération d’étres absolument différents, dont Vorigine, Age, l’ancienneté d’ immigration sont trés divers. On sera donc réduit a faire des chorologies spéciales pour chaque groupe homogéne, ce qui me sera pas moins intéressant.” (E, GH. RACOVITA, 1907, p. 459)

Neobisium blothroides (Tömösváry, 1882) (Neobisiidae, Pseudoscorpiones): an endemic species from Romania

Article keywords: Pseudoscorpions, Neobisium blothroides, endemism, relicts, cave fauna, Romania

Article: The species “Obisium’ blothroides was discovered and described from a single cave nr. Mehadia, Romania. At that time, Mehadia was part of the Austro-Hungarian Empire, which accounts for the later hence further mistake made by BRIER (1932, 1963) who claimed that the species inhabits “SO-Qngarn”. However, Neobisium blothroides canbe regarded:as an endemic and relict form inhabiting a number caves in Romania, already cited in this paper

Researches on the mesovoid shallow substratum (MSS) from Romania

Article keywords: MSS, colluvial deposits, subterranean fauna, troglobitic fauna

Article: In order to continue the researches on the MSS (the MSS of the French authors) from Romania, between June 1998 and September 2001, we made 120 drillings in calcareous and non-calcareous colluvial deposits from the West of the Southern Carpathians by placing buried Barber traps. Among them, we selected only 29 traps from which fauna with biospeological significance for the MSS was collected

Contributions to the knowledge of riparian Coleoptera and Araneae from the Natural Reserve “Codrii Seculari Slătioara” (Bucovina, Romania)

Article keywords: Riparian fauna, Coleoptera, Araneae, Natural Reserve "Codrii Seculari Slătioara", Romania

Article: Both beetles and spiders are well represented in the riparian habitats by numerous predatory species, with different ecological niches in limiting the local populations of primary or secondary consumers. The Natural Reserve Slatioara — one of the oldest and well conserved primary forests from Romania (and also from Europe) — offers us the opportunity to study an almost unaltered riparian association of Coleoptera and Araneae, arthropods proofed to be very important in the biodiversity and pollution evaluation of moist areas (and not only)

Sur les Cheiropteres de la collection "Biospeologica"

Article keywords: Biospeologica collection, bat species collected, archive documents, letters exchange, Emil G. Racoviță, Knud Andersen, Martin Hinton, British Museum

Article: En dépit du fait que la Collection «Biospeologica» contenait en son temps un nombre assez important de Chéiroptéres, aucun des mémoires qui composent la série homonyme publiée 4 la longue dans la revue Archives de Zoologie expérimentale et générale ne traite de ces Mammiféres troglophiles. Des documents d’archives et des informations extraites des neuf séries de l’«Enumération des grottes visitées» ont permis toutefois de dresser un inventaire partiel des espéces collectées durant lintervalle 1905-1957, ainsi que de leurs grottes de provenance

Palaeoecology and Biostratigraphy

Article keywords: Ostracodes, mollusks, biostratigraphy, Meotian, Pontian, boundary, palaeoecology

Article: Undoubtedly, the fauna (ostracodes and mollusks) of the Upper Neogene from the Dacian basin is well known for its empirical sense and the biostratigraphy (exclusively focused on mollusks) is clear and generally without major ambiguities. However many “biostratigraphical events”, either boundaries or fauna changes, have no plausible explanations

The Colibituri Cave (The Vâlcan Mountains – The Southern Carpathians) Mineralogical data

Article keywords: Colibituri Cave, Valcan Mountains, Southern Carpathians, mineralogy, XRD, hydroxylapatite, leucophosphite, calcite, alpha-quartz, illite

Article: In this paper there are presented data obtained after a first mineralogical analysis made in the Colibituri Cave. Based on extensive X-ray powder diffraction study, the presence of hydroxylapatite, leucophosphite, calcite, a-quartz and illite was determined. Practically, the whole southern part of the Valcan Mountains, which is included in the Gorj county, is mostly made of carbonated rocks from the Middle Jurassic-Lower Cretaceous age, whereas those from the southern sector of the Sohodol Gorges, where the Colibituri Cave lies, are attributed to the Aptian-Barremian interval developed in urgonian facies (skeletal, peletoid and biolitical limestone)
