Recorded Occurrence

Abstract On May 1 5, 201 2 an individual of Levant sparrowhawk Accipiter brevipes was observed at the southern edge of Trebišov town in eastern Slovakia, situated in the Východoslovenská rovina Lowlands. The sighting was documented with photographs. This is the first recorded occurrence of this species in terms of the bird fauna of Slovakia. The present article describes in detail its distribution and breeding in eastern Hungary and western Romania, based on an isolated population in the Pannonian Basin at the north-western edge of its breeding range. The occurrence of the Levant sparrowhawk beyond the boundaries of its breeding range and outside the Pannonian Basin consists mostly of rare movements by young individuals (northern Moravia, central and northern Poland) far north of its breeding range. An adult male was observed in south-eastern Poland in the pre-breeding period, and in Slovakia an adult female was observed in the breeding period.

Abstract The population of the red-footed falcon in Slovakia inhabits the north-western edge of the species' breeding range. This breeding population is relatively small and came near to extinction during the population decline of this species in central Europe in recent decades. Thanks to increasing numbers of breeding pairs in Hungary, the Slovak population began to grow again. Moreover, some differences in breeding biology associated with breeding in nest boxes were found. Here we describe the dependence of the small isolated breeding population in Slovakia on the core population in the more eastern parts of the Carpathian Basin, and the impact of supporting activities (nest boxes) on this raptor species in Slovakia.

These mountains are famous and intensely studied for their important non-ferrous metal resources. Few data were published about the geothermal potential of this area. More works have been dedicated to mineral waters, while the geothermal waters are only briefly described, without sufficient emphasis on them. The current research is focusing on the two categories, cold mineral and geothermal water in the Apuseni Mountains, compared to the surrounding areas, in order to better understand their genesis and the general context of the geothermalism in the study region. A preliminary survey of these waters was done in 2019 taking water and gas samples from 41 sources.</p><p>The pH varies between 6.00 and 9.02 and, the lowest values have been measured in the CO<sub>2</sub>-rich waters of the Southern Apuseni Mountains. Water temperatures vary between 11.1 <sup>â—‹</sup>C and 81 <sup>â—‹</sup>C. In the southern part of the Apuseni Mountains, the geothermal waters are of the calcium bicarbonate type (Ca-HCO<sub>3</sub>), while in the north-western part, the sodium bicarbonate type (Na-HCO<sub>3</sub>) is more common. The water sources from the north-western part are close to the Pannonian Basin and show features comparable to the thermal waters of this basin. Conductivity values show significant variations between 142 and 2040 µS/cm, but regional homogeneities were observed. The highest concentration of bicarbonate was measured in one of the localities of the northern study area (BeiuÅŸ Depression - 3318.4 mg/L). The dissolved heavy metal concentrations (Zn, Pb, Cd, Cr, Ni, Cu, Fe) in the water samples were also measured. For all the investigated waters, the heavy metal content was low. The highest concentrations were recorded for Fe 342.90 µg/L and Zn 86.14 µg/L.

The Apuseni Mountains are located between the large geothermal area of the Pannonian Basin and the low thermal flux Transylvanian Basin. Thermal and mineral waters have been sampled from 42 points along a NW-SE transect. The general chemistry and the water isotope (deuterium and oxygen-18) composition were analyzed. Most of the thermal aquifers are located in carbonate reservoirs. The waters mainly belong to the Ca-HCO3 hydrochemical type, excepting the western side, towards the Pannonian Basin, where the Na-HCO3 type may occur. The isotope composition indicates aquifer recharge from precipitation. The geochemical characteristics and the structural position of the study area suggest two distinct geothermal contexts. The Southern Apuseni area geothermal features are likely connected to the Neogene—Early Quaternary magmatic activity from the Mureş Valley and Zarand Depression. The geothermal manifestations in the north-western part of the study area, at the border between the Northern Apuseni and the Pannonian Depression, share features of the latter one.

Abstract The golden jackal is a mesocarnivore with a rapidly expanding European range, where current resident breeding populations occupy much of the Balkans, Pannonian Basin and the Black and Caspian seas coasts. Despite numerous post-2000 records, breeding of this species in the newly colonized regions of Central and Northwestern Europe remained unconfirmed. Photography- and direct observation-based evidence obtained in 2017 from Central Bohemia, Czech Republic, indicates a north-western shift in the breeding range over 300 km from the closest known breeding jackal population in Pannonian Basin.

Identifying rock types and establishing their chemico-mineralogical composition are essential components of geological characterization process of hydrocarbon reservoirs. Based on the global chemical-mineralogical composition and rock type, recipes and treatments are developed aimed to prevent the blocking of productive formations both during drilling and during the production of wells. Knowing the detailed lithology helps us in the optimum choice of drilling fluids compatible with the formations on the investigated structure and also to choosing recipes during acidizing/stimulation treatment of the wells. The complex geological investigations (petrographic study, EDX, XRD) performed on cores/sample rocks allow through the information provided a better characterization of the rocks in a reservoir and the efficient modelling of the hydrocarbon reservoir production. In the paper is presented a detailed description based on macroscopic and microscopic petrographic investigations, EDX spectrometry and X-rays diffraction of several drill cuttings collected in the wells spudded in a gas field in north-western Romania (Pannonian Basin).

Recorded Occurrence

The first recorded occurrence of Hirudo verbana Carena, 1820 (Hirudinea: Arhynchobdellida: Hirudinidae) in Romania In 2005, a Hirudo verbana specimen was observed in Stracoş Valley, within the Tăşad Reserve (Bihor county, north-western Romania). Since the coloration pattern of this once forgotten species matches its genetic differentiation, the identification of the specimen as belonging to the southeastern European H. verbana appears plausible. The species was previously cited in southern, central and eastern Europe, but not in Romania. Therefore, the present observation might be its first recognized occurrence in the country. As recently pointed out, H. verbana is one of the three species commonly known as the European medicinal leech and the most abundant as such. Most international and national conservation legislation containing only H. medicinalis (including IUCN, CITES, Berne Convention) needs completion, according to the new taxonomy.
