– The karyotypes of eight species of Geotrupidae are reported and illustrated. Ceratophyus hoffmannseggi Fairmaire has seven pairs of autosomes and sex chromosomes which are Xy (!), XX ("), while Anoplotrupes stercorosus (Scriba), Geotrupes spiniger Marsham, Sericotrupes niger (Marsham), Thorectes geminatus (Gené), T. intermedius (Costa), T. lusitanicus (Jekel) and Trypocopris vernalis (L.) all...

The purpose of this work was to conduct plant monitoring in the vicinity Lake Kravtsovo within framework preserving animal and world biodiversity. Lake-swamp - a unique object Stavropol upland, here you can study diversity almost half entire flora fauna Territory. 139 species vascular plants were registered studied territory, among which 11 are subject protection – Paeonia tenuifolia L., Cladiu...

The combination of adaptive optics and coronographic techniques providing at the same time high angular resolution and high dynamic range is a powerful tool to study the close environment of bright objects in different fields of astrophysics (search for brown dwarfs and giant extra-solar planets around nearby stars, search for circumstellar disks, study of AGB outflows, etc). We present in this...

We present results of a coronographic imaging search for circumstellar dust disks with the Adaptive Optics Near Infrared System (ADONIS) at the ESO 3.6 m telescope in La Silla (Chile). 22 candidate stars, known to be orbited by a planet or to show infrared excess radiation, were examined for circumstellar material. In the PSF-subtracted images no clear disk was found. We further determine the d...
