Data on Population Dynamics of Three Syntopic Newt Species from Western Romania
Alfred-S. Cicort-Lucaciu,Nicoleta-R. Radu,Cristiana Paina,Severus-D. Covaciu-Marcov
Ecologia Balkanica , 2011,
Abstract: We studied the population dynamics of three syntopic newt species [Mesotriton alpestris (Laurenti, 1768), Lissotriton vulgaris (Linnaeus, 1758) and Triturus cristatus (Laurenti, 1768)] in Zarand Mountains (Arad County, Romania). M. alpestris had the shortest aquatic phase, approximately two months, out of which the nuptial display was 2-3 weeks long. L. vulgaris and T. cristatus spent three months in the habitat, having a nuptial display of 2-3 weeks for L. vulgaris, and of 4-5 weeks for T. cristatus. M. alpestris had the highest degree of reproductive synchronization, while this was the lowest at T. cristatus. Males from all three species had a higher affinity for the aquatic habitat than females. The population size was estimated at 769 for L. vulgaris, 588 for T. cristatus, and 294 for M. alpestris. Balanced sex ratio was observed in the peak of breeding activity for all species.
Implication upon Herpetofauna of a Road and its Reconstruction in Carei Plain Natural Protected Area (Romania)
Alfred-S. Cicort-Lucaciu,Severus-D. Covaciu-Marcov,Horia V. Bogdan,Istvan Sas
Ecologia Balkanica , 2012,
Abstract: In autumn 2011 we monitored a 5 km long road, paved with cobblestone, situated in Carei Plain Natural Protected Area, a road that is due to be modernized and continued across the border into Hungary. Dead bodies from eight different animal groups were observed on the road, amphibians presenting the greatest amount. The most frequent were the Triturus dobrogicus corps, a species with conservation importance. The amphibians were affected in the areas where the road is neighboring the wetlands, while on the opposite pole sits the area with acacia plantations. The high number of mortalities recorded on the road, despite the low traffic speed, is alarming. It is likely that the modernization of the road that will surely increase its traffic and the speed of the vehicles, will make the situation even worse. However, the rebuilding could contribute to the reduction in the impact on amphibians, if certain measures are considered while planning the action. Thus, in the areas near the wetlands, there should be undercrossings, fences and speed limits. In this way, the modernization would at least represent an experiment regarding the diminution of the road’s impact on amphibians.
Eryx jaculus (Reptilia, Boidae) north of Danube: a road-killed specimen from Romania
Severus D. Covaciu-Marcov,Sára Feren?i,Alfred S. Cicort-Lucaciu,István Sas
Acta Herpetologica , 2012,
Abstract: In September 2011 we identified a killed specimen of Eryx jaculus on the road between the towns of Turnu M gurele and Corabia, in southern Romania. This seems to be the first record of the species north of the Danube. Although surprising, the identification of E. jaculus in the area is interpreted in the light of the presence of other species of herpetofauna in the Danube floodplain with similar ecological requirements, reaching here their northern distribution limit. Survival of the species appears to be favoured by the existence of some protected areas in the region.
Lissotriton vulgaris paedomorphs in south-western Romania: a consequence of a human modified habitat?
Severus D. Covaciu-Marcov,Istvan Sas,Alfred ?. Cicort-Lucaciu,Horia V. Bogdan
Acta Herpetologica , 2011,
Abstract: A Lissotriton vulgaris paedomorph population was identified for the first time ever in south-western Romania. The newts inhabiting a permanent but artificial habitat, surrounded by agricultural fields.
Note about the feeding of a Triturus cristatus population from Sustiu (Bihor county, Romania)
Alfred St. CICORT-LUCACIU,Letitia BOGDAN,Annamaria TOTH,Iuliu ORBAN
Analele Universitatii din Oradea, Fascicula Biologie , 2006,
Abstract: The Triturus cristatus population from u tiu has optimal feeding conditions, all the individuals having stomach contents. The newts had consumed diverse preys belonging to several prey taxa as well as vegetal remains, shed-skins and eggs. The feeding of the individuals of the two sexes is different, females feeding more intensively but less diversified than males. It seems that in this case the two sexes use different strategies to obtain the preys.
Food composition of some low altitude Lissotriton montandoni (Amphibia, Caudata) populations from North-Western Romania
Covaciu-Marcov S.D.,Cicort-Lucaciu A.?.,Sas I.,Cup?a Diana
Archives of Biological Sciences , 2010, DOI: 10.2298/abs1002479c
Abstract: The diet of some populations of Lissotriton montandoni from north-western Romania is composed of prey belonging to 20 categories. The food components of the Carpathian newts are similar to those of other species of newts. Most of the prey are aquatic animals, but terrestrial prey also has a high percentage abundance. The consumed prey categories are common in the newts' habitats as well, but in natural ponds the prey item with the highest abundance in the diet is not the most frequent one in the habitat. Thus, although the Carpathian newts are basically opportunistic predators, they still display a certain trophic selectivity.
Lissotriton vulgaris paedomorphs in south-western Romania: a consequence of a human modified habitat ?
Severus-Daniel Covaciu-Marcov,Istvan Sas,Alfred-Stefan Cicort-Lucaciu,Horia-Vlad Bogdan
Acta Herpetologica , 2011,
Abstract: A Lissotriton vulgaris paedomorph population was identified for the first time ever in south-western Romania. The occurrence of this paedomorphosis is explained by the particularities of the area, the newts inhabiting a permanent but artificial habitat, surrounded by agricultural fields. Thus, the presence of an acceptable aquatic habitat together with the absence of a suitable terrestrial one triggered the occurrence of paedomorphosis.
New cases of winter-active amphibians in the thermal waters of Banat, Romania
Bogdan Horia-Vlad,Covaciu-Marcov Severus-Daniel,Antal Cornel,Cicort-Lucaciu Alfred-?tefan
Archives of Biological Sciences , 2011, DOI: 10.2298/abs1104219b
Abstract: In the winter of 2010/2011 we identified 6 new thermal habitats, with winter-active amphibian populations in the Banat region of south-western Romania. The diversity of the amphibian species was small, only 2 species were observed: Bombina bombina and Pelophylax ridibundus. In waters with high flow and temperature, the number of winteractive frogs reached several hundred. All the new thermal habitats are artificial, being subjected to a powerful anthropogenic pressure.
The trophic spectrum of a Triturus cristatus (Laurentus 1768) population from Plopi Mountains area (Bihor County, Romania)
A.St. Cicort-Lucaciu,A. Ardeleanu,D. Cupsa,N. Naghi
North-Western Journal of Zoology , 2005,
Abstract: Crested newts eat mainly invertebrates, but may also ingest vegetal particles, Amphibian eggs or shed skins. Besides the shed skins of conspecific individuals, we have also identified shed skins of Bombina variegata, and even of Lacerta agilis. Due to the particular morphology of the habitat, the coming of the warm season brings about differences in the accessibility of different prey categories from one part to another of the inteu pond. This difference in the trophic offer causes modifications in the trophic spectrum, the adoption of the “sit-and-wait” feeding strategy, an increase in the number of empty stomachs, and indicates a decrease in the preying capacity of newts that prepare to leave the aquatic environment. Quantitatively, the most important prey taxa to the studied population are tadpoles and Nematocera larvae.
Argument. Why Should We Study Everyday Lives of Catholic Women
Mihai Lucaciu
Journal for the Study of Religions and Ideologies , 2003,
Abstract: Assuming that all cultures have gender roles, religion affects women differently than men. What have Catholic women’s religious lives, roles, and images been like? Although all women share a common experience of being women, differences of class, race, religion, culture, and sexual orientation separate them, and therefore taking into account women’s experiences and views can be a difficult task in complex religious contexts. Religious practices have different significance to men and women and their engagement is different. In foraging and horticultural societies, women and men have more egalitarian and complementary roles and women play significant roles in religion – while in agrarian societies the situation is quite different. Large denominations such as Roman Catholicism, the Eastern Orthodox Church, and Orthodox Judaism are strongly against the ordination of women to sacramental ministry. Catholic women are left with a God with whom they cannot identify and who cannot identify with them.
