The aim of this study was to characterize karyotypes of central European spiders of the genera Arctosa, Tricca, and Xerolycosa (Lycosidae) with respect to the diploid chromosome number, chromosome morphology, and sex chromosomes. Karyotype data are reported for eleven species, six of them for the first time. For selected species the pattern in the distributions of the constitutive heterochromatin and the nucleolar organizer regions (NORs) was determined. The silver staining technique for detecting NORs of lycosid spiders was standardized. The male karyotype consisted of 2n = 28 (Arctosa and Tricca) or 2n = 22 (Xerolycosa) acrocentric chromosomes. The sex chromosome system was X1X20 in all species. The sex chromosomes of T. lutetiana and X. nemoralis showed unusual behaviour during late diplotene, namely temporary extension due to decondensation. C-banding technique revealed a small amount of constitutive heterochromatin at the centromeric region of the chromosomes. Two pairs of autosomes bore terminal NORs. Differences in karyotypes among Arctosa species indicate that the evolution of the karyotype in this genus involved autosome translocations and size changes in the sex chromosomes. Based on published results and those recorded in this study it is suggested that the ancestral male karyotype of the superfamily Lycosoidea consisted of 28 acrocentric chromosomes. and Petr DOLEJŠ, Tereza KOŘÍNKOVÁ, Jana MUSILOVÁ, Věra OPATOVÁ, Lenka KUBCOVÁ, Jan BUCHAR, Jiří KRÁL.
This study attempts to analyse the basic tendency of the Austrian state to regulate and control the move of inhabitants. After fading of population theories that saw state wealth in the population growth, therefore supporting immigration, the period of the Napoleonic wars came that became catalyser of a rapid legal development in the field of immigration. Entirely unprepared Austria specialised its basic strategies in respect of foreigners and of the population move control. The attitude of the state to foreigners determines their "utility for the state", which finally results in the establishment of categories of foreigners: privileged, facultative, and undesirable. Applying practical examples, the study specifies such classification of foreigners and of their destinies within the Austrian state. The privileged: The Netherlands textile specialists in the fine cloth factory in Náměšť near Brno; Turkish merchants and subjects of the High Porte of the Jewish religion; the facultative: the Netherlands state officers who, due to their loyalty to Austria, had to leave their homeland after the occupation of the Austrian Netherlands (later Belgium) by the French Republic; the undesirable: The French who were potentially suspected of propagation of revolution ideas or of espionage; here examples of the high French nobility have been specified, i.e. of the de Bombelles family and of dismissed highranking officers of the elite Prince de Condé Regiment (then in active service of Russia)., Zdeňka Stoklásková., and Obsahuje bibliografické odkazy
