Data upon the terrestrial isopod fauna from the western slope of Oas Mountains, Romania Sára Ferenţi1,2, Éva-Hajnalka Sas-Kovács3, István Sas-Kovács1 & Severus-Daniel Covaciu-Marcov1 1University of Oradea, Faculty of Sciences, Department of Biology, Universităţii str. 1, Oradea 410087, Romania 2Iosif Vulcan National College, Jean Calvin str. 3, Oradea, Romania 3Babeş-Bolyai University, Faculty of Biology and Geology, Department of Biology, Gheorghe Bilaşcu (Republicii) str. 44, Cluj-Napoca 400015, Romania article no.: ER18201301 Summary: In the western slope of Oas Mountains we identified 16 terrestrial isopod species: Ligidium germanicum, L. hypnorum, Hyloniscus riparius, H. transsilvanicus, Trichoniscus sp., Cylisticus convexus, Protracheoniscus politus, Porcellium collicola, P. conspersum, Trachelipus difficilis, T. arcuatus, T. nodulosus, T. rathkii, Porcellio scaber, Armadillidum vulgare and A. versicolor. The terrestrial isopod assemblages are typical for mountain regions. The species composition proved to be similar with the ones previous identified in the neighboring plain areas, suggesting their common history. The most favorable habitats were wetlands and coppices. Even in natural habitats the terrestrial isopods can use artificial shelters, fact that suggests their opportunistic behavior in the case if the habitat’s characteristics are optimal. The disturbed habitats show a relatively rich isopod fauna, they sheltering both generalists and species with narrow ecological valance. Key words: terrestrial isopods, habitats, connectivity, human impact, forest, wetlands. e-mail: ferenti_sara@yahoo.com	[details, abstract]	[pdf]
Travelling isopods: Oniscus asellus (Crustacea, Isopoda) in an anthropogenic habitat from north-western Romania Sára Ferenţi1,2 & Severus-Daniel Covaciu-Marcov1 1University of Oradea, Faculty of Sciences, Department of Biology, Universităţii str. 1, Oradea 410087, Romania 2Iosif Vulcan National College, Jean Calvin str. 3, Oradea, Romania article no.: ER18201302 Summary: Oniscus asellus was identified in an anthropogenic habitat from north-western Romania, namely at the entrance of the cellar from an old, ruined castle. The species was most likely introduced by accident, being presently found only within the confines of this habitat. This limited distribution of the species to only one anthropogenic habitat proves that O. asellus is not expanding and does not present a threat to the native terrestrial isopod fauna. Key words: introduced species, artificial habitat, anthropogenic activities. e-mail: ferenti_sara@yahoo.com, sever.covaciu@yahoo.com	[details, abstract]	[pdf]
An annotated list of Tipulidae (Insecta, Diptera) from Romania Edina Török1,2, Levente-Péter Kolcsár1  & Lujza Keresztes1 1Babeş-Bolyai University, Faculty of Biology and Geology, Hungarian Department of Biology and Ecology, Clinicilor Street 5-7, Cluj-Napoca, Romanian. 2University of Szeged, Department of Ecology, Szeged, Közép fasor 52, Hungary article no.: ER18201303 Summary: Since the last updated list of Tipulidae of Romania (2007) new data were accumulated in the last seven years. A number of 5 species are new records to the Romanian fauna, as Tipula (Acutipula) latifurca Vermoolen, 1983; Tipula (Acutipula) vittata Meigen, 1804; Tipula (Lunatipula) recticornis Schummel, 1833; Tipula (Pterelachisus) pseudopruinosa Strobl, 1895 and Tipula (Savtshenkia) signata Staeger, 1840. A short comment on general distribution of species, with a critical revision on the published data is added. Original pictures on male genital and wing is also presented. Key words: Tipulidae, new records, Romania. e-mail: edinatorok7@gmail.com, kolcsar.peter@gmail.com, keresztes2012@gmail.com	[details, abstract]	[pdf]
Differences in adult phenology, demography, mobility and distribution in two syntopic ecotypes of Maculinea alcon (cruciata vs. pneumonanthe) (Lepidoptera: Lycaenidae) from Transilvania (Romania) Natalia Timuș1, Cristina Craioveanu1, Cristian Sitaru1, Alexandra Rus1 & László Rákosy1 1Department of Taxonomy and Ecology, Babeş-Bolyai University, Clinicilor 5-7, 400006 Cluj-Napoca, Romania article no.: ER18201304 Summary: We present a Mark-Release-Recapture study performed on the populations of two Maculinea alcon ecotypes in a Natura 2000 site from Transylvania, Romania. The Natura 2000 site harbours cultural landscapes with highly biodiverse semi-natural grasslands, among which several meso-hygrophilous meadows represent the only areas with 4 syntopically occurring European Maculinea butterfly species and two syntopically occurring ecotypes of M. alcon. Previous studies have shown that the two M. alcon ecotypes use different host plants and host ants; however our study is the first to focus on adult butterfly population ecology and distribution. In the case of M. alcon, conservation of the species has to consider the ecological needs of both ecotypes in order to be meaningful. The unique syntopical occurrence of both ecotypes makes population ecology studies in this area especially important for providing information for conservation management. Key words: population ecology, mark-release-recapture, Maculinea alcon ecotypes, syntopic populations. e-mail: nataliatimuss@gmail.com, cristinacraioveanu@gmail.com	[details, abstract]	[pdf]
Ichneumon balteatus (Hymenoptera: Ichneumonidae) – a new parasitoid species of Maculinea alcon butterflies (Lepidoptera: Lycaenidae) Natalia Timuș1, Raoul Constantineanu2 & László Rákosy1 1Department of Taxonomy and Ecology, Babeş-Bolyai University, Clinicilor 5-7, 400006 Cluj-Napoca, Romania. 2Biological Research Institute, Lascăr Catargiu Street 47, 700107 Iaşi, Romania article no.: ER18201305 Summary: During 2010 and 2012 several Maculinea alcon pupae were collected from colonies of Myrmica scabrinodis (family Formicidae) in the Natura 2000 site `Dealurile Clujului Est` (Transilvania, Romania). Subsequently, 8 individuals of the ichneumonid species, Ichneumon balteatus, emerged from these pupae. Until this discovery, Ichneumon eumerus was the only species described as a parasitoid of M. alcon. Moreover, Melitaea cinxia and Calliteara pudibunda are the only known hosts of I. balteatus. Thus, the relationship between Maculinea alcon and Ichneumon balteatus is described here as a host-parasitoid association new to science. Key words: Maculinea alcon, Ichneumon balteatus, Myrmica scabrinodis, social parasite, parasitoid, Transylvania, Romania. e-mail: nataliatimuss@gmail.com, racon38@yahoo.com, laszlorakosy@hasdeu.ubbcluj.ro	[details, abstract]	[pdf]
