Astronomical alignments of paleo-Christian basilicas in Romania

In this paper we present the first comprehensive study of the astronomical alignments of paleo-Christian basilicas located in present day Romania. 20 basilicas from 10 sites have been investigated using a digital compass and tools such as Google Earth, Stellarium, and heywhatsthat.com. Results show that except two all fall within the solar sunrise arc. Of these some point to the rising Sun during the feast days of well-known Christian saints. The two exceptions at Argamum and Dinogeția indicate that the basilicas may be converted. The astronomical analysis in these two cases indicates a possible alignment with the moonrise during the major lunar standstill and the rising of the stars Arcturus, Castor, Mirach, and Algiebe

A 2500-yr late holocenemulti-proxy record of vegetation and hydrologic changes from a cave guano-clay sequence in SW Romania

We provide sedimentological, geochemical, mineral magnetic, stable carbon isotope, charcoal, and pollen-based evidence froma guano/clay sequence in Gaura cuMuscă Cave (SWRomania), fromwhichwe deduced that from ~1230 BC to ~AD 1240 climate oscillated betweenwet and dry. From ~1230 BC to AD 1000 the climate was wetter than the present, prompting flooding of the cave, preventing bats fromroosting, and resulting in a slowrate of clay accumulation. The second half of the MedievalWarm Period (MWP) was generally drier; the cave experienced occasional flash flooding in between which maternity bat roosts established in the cave. One extremely wet event occurred around AD 1170, when Fe/Mn and Ti/Zr ratios show the highest values coincident with a substantial increase of sediment load in the underground stream. The mineral magnetic characteristics for the second part of the MWP indicate the partial input of surface-sourced sediments reflecting agricultural development and forest clearance in the area. Pollen and microcharcoal studies confirm that the overall vegetation cover and human land use have not changed much in this region since the medieval times

A new cave-dwelling species of the genus Geophilus Leach, 1814 (Chilopoda: Geophilomorpha) from the chemoautotrophic-based Movile Cave (Southern Dobrogea, Romania)

Geophilus zagreus sp. nov., a troglomorphic geophilid endemic to the Movile Cave sulfidic groundwater ecosystem, is described and illustrated. It is distinguished from other European Geophilus species by a high number of coxal pores on the ventral side of the coxa of the last pair of legs. Its affinities with the other two troglobitic species of the genus are discussed. The mitochondrial COI barcode is sequenced for the new species and phylogenetic analysis is carried out to elucidate its placement within Geophilus. Other syntopic Chilopoda from Movile cave are listed.https://www.zoobank.org/urn:lsid:zoobank.org:act:D549ACAF-5DE4-403E-8D1A-5E6232A635E

DOI:10.2298/ABS0703233G ON SOME ONISCIDEA AND DIPLOPODA FROM THE RETEZAT MASSIF. FIRST RECORD OF PORCELLIUM PRODUCTUM FRANKENBERGER, 1940

The Oniscidea and Diplopoda from the Retezat Massif are relatively well studied, the Diplopoda being better known than the Oniscidea. Up to now, only two species of Oniscidea were recorde

Urban areas as hot-spots for introduced and shelters for native isopod species

Isopod assemblages were studied in Budapest, capital of Hungary. The analyses of literary and field data revealed a high species richness (28 species), compared to the total species number (57) in Hungary. Habitats characteristics for the city were categorized as native forests, urban forests, gardens of Buda, gardens of Pest, public parks, densely built-up areas and botanical gardens. We hypothesized that isolated and diverse habitat patches in the city matrix of Budapest support the introduction and establishment of exotic species and the survival of native ones. The composition of assemblages varied among sampling sites, but were characteristic for the biotope categories. We concluded that forests, parks and gardens play an important role in the survival of native isopod populations. Species numbers were highest in the gardens of Buda and in the botanical gardens (both 17 species). The overall presence of cosmopolitan and disturbance-tolerant species indicates an ongoing homogenization process.
