Kárpátalja védett hajtásos növényfajainak kromoszómaszám értékei – előzetes eredmények = Chromosome Numbers of Protected Vascular Plant Species of Transcarpathia, Ukraine – Preliminary Results

Kárpátalja alföldi területei a Pannonicum flóratartomány részét képezik, így a terület növényvilágának megismerése szervesen kapcsolódik a magyarországi flóra kutatásához. A fajok előfordulása mellett a citológiai bélyegek minél pontosabb ismerete is szükségszerű, hiszen ezek fontos evolúciós vonalakra deríthetnek fényt. Jelen munka a kárpátaljai védett és veszélyeztetett edényes növények (207 faj) kromoszómaszámainak összefoglalásával foglalkozik irodalmi adatok alapján, valamint a taxonok védettségi státuszának összehasonlításával Ukrajna Vörös Könyve és a Nemzetközi Természetvédelmi Unió (IUCN) kategóriái szerint. A vizsgált 207 védett faj közül 203-nak fellelhető a kromoszómaszám adata, de ebből mindössze 8 fajét ismerjük kárpátaljai populációk vizsgálatából. The plains of Transcarpathia, the northeastern Carpathian Basin region, belong to the Pannonian Floristic Province (Pannonicum). Therefore, understanding the region’s plant diversity is indispensable for Hungarian floristic research. A precise knowledge of cytological markers is essential, as they can shed light on important evolutionary lineages. This study summarizes the chromosome number data of protected and endangered vascular plant species (altogether 207 species) in Transcarpathia, based on the available literature. The work also compares the protection status of taxa according to the Red Book of Ukraine and the Red List of Threatened Species issued by the International Union for Conservation of Nature (IUCN). Of the 207 protected species examined, the chromosome number is known for 203 species, of which only 8 originate from the study of Transcarpathian populations

Experience from a light trap Lepidoptera survey in a populated settlement: effects of meteorological factors and changes in lunar phases

In the framework of the research, light trap Lepidoptera collections were carried out in the territory of a settlement (Velyki Berehy, Zakarpatska Oblast, Ukraine), which is bordered by nature reserves, forests, and agricultural areas, as well as by the remains of a large marsh (Szernye bog) that had been drained in the past. A Jermy light trap with a household LED bulb was used to capture the moths and butterflies. In addition to assessing the Lepidoptera fauna of the area, the study aimed to find out which species of Lepidoptera are attracted to energy-saving light bulbs commonly used in households in a settlement located in a habitat-diverse environment. In addition to the artificial light pollution conditions and other anthropogenic influences of the settlement, the direction and magnitude of the effects of temperature, relative humidity, cloud cover, wind speed, and moon phase parameters at the time of collection on the flight trends of nocturnal Lepidoptera species were also investigated. A total of 97 days of collecting between May 2018 and May 2019 resulted in the collection of 122 Lepidoptera species from 16 families. In terms of their ecological requirements, species were found in closed and open forest, forest edge, scrub, meadow, actively cultivated and abandoned agricultural areas, as well as in dry and wet areas. Several species considered being agricultural, forestry, or horticultural pests were identified, but not in abundance. Among the environmental variables, temperature variation showed a strong significant positive correlation with daily species numbers and abundance, while relative humidity, wind speed, cloud coverage and moon phases showed varying degrees of negative correlation, but were generally weak. The effects of the interactions of natural and man-made environmental influences on living organisms are difficult to assess objectively, but their research is of paramount importance for the long-term effective conservation of habitats of particular conservation value and for the preservation of their biodiversity
