This paper brings a contribution to the distribution of genus Stagnicola Jeffreys, 1830 and Catascopia Meier-Brook & Bargues, 2002 in the Czech Republic. Occurrence of four species has been confirmed in the Czech Republic so far. Two species – Stagnicola corvus (Gmelin, 1791) and S. palustris (O.F. Müller, 1774) (including S. turricula (Held, 1836)), are widespread and common especially in lowlands along bigger rivers (Labe, Ohře, Morava, Dyje, Odra). Occurrence of S. fuscus (Pfeiffer, 1821) is restricted to the territory of the north-western part of Bohemia and Catascopia occulta (Jackiewicz, 1959) is a rare species with only two known sites.

The area of the North-Western Bohemia (NWB, covered by three from the 1st January 2000 in the Czech Republic 14 existing new counties) will be divided from 1st January 2003 - in compliance with ongoing public administration reforms - to 33 new and smaller "districts" (instead of more than 40 years existing 14 districts). The paper deals with internal territorial division of public administration units (counties and districts) of the NWB area in the past (see enclosed tables). In order to assess and classify both necessity and significance of recently proposed centers and their future areas the author applies to assess their "population size" (which is one of key aspects used in the reform proposals). According to the new districts "population size" - the average size is only 47 thsd inh. The author identifies group of the "smaller and disputable districts", in which he looks one of very dispute and risky results of the reform. This is emphasized by comparison with the simultaneous development and achieved results of the territorial division in the neighbouring countries Saxony/Germany and Lower Silesia/Poland. After completion of this paper the Senat of the Czech Republic approved this proposal, but moreover the number of all the new "districts" for the whole CR territory grow up from 194 up to 205 units (instead of 76 existing districts).

Based on 25 records (both published and new) we summarize the recent distribution of Pipistrellus kuhlii in the Czech Republic and discuss possible colonization routes. The species colonized a major part of the Czech Republic during 14 years since its first record in 2007. Based on locations and chronology of the records it seems that the eastern part of the Czech Republic (Moravia) was colonized from the south along the Dyje and Morava rivers, while in Bohemia, two possible routes may have existed: one from the south along the Vltava river from the Danube valley, and another from the east or south-east along the valley of the Svitava and Orlice rivers. Given the fact that already in 2018 the presence of P. kuhlii was confirmed in Saxony, which predated the species confirmation in the north-western and central parts of Bohemia, we do not exclude possible existence of a third colonization route along the Labe river from the north-west (Germany). All the records come from human settlements, typically cities or towns, and dates of the records suggests the year-round occurrence. At least four records (including two roosts of maternity colonies), all from Moravia, proved reproduction of this bat in the country. All examined individuals displayed pelage and skin colouration patterns typical for P. kuhlii kuhlii.

The article aims to evaluate the research provenance plot established in 1980 in locality No. 214 – Hrubá Skála (in the north of the Czech Republic), where nine provenances of grand fir (Abies grandis (Douglas ex D. Don) Lindley) provided in the framework of the International Union of Forest Research Organizations project, and one provenance of grand fir, Norway spruce, silver fir and Douglas-fir from a standard commercial source are tested. We present the results of tree height, stem DBH, stem volume production and health status after 36 years. The results correspond with similar experiments in the Czech Republic and abroad and suggest that grand fir provenances from Vancouver Island (British Columbia, Canada) and the Washington (USA) State coastal region show the best production features, while the Oregon Cascades, Idaho and Montana provenances grow more slowly. Comparison with other tree species indicates that the production of grand fir at the investigated age exceeds the production of both Norway spruce and silver fir, and equalizes or gently exceeds even Douglas-fir.

This study contributes to the knowledge of central European clitellates by creating a check-list of Oligochaeta (sensu oligochaetous Clitellata; Erséus 2005) of the Czech Republic, exclusive of taxa in the family Enchytraeidae. In total, 95 aquatic oligochaete species representing 43 genera are reported for the Czech Republic. Rare species are highlighted and associated with the categories for threatened species as outlined by the International Union for the Conservation of Nature. The first records of Trichodrilus strandi Hrabě, 1936, Pristina jenkinae (Stephenson, 1931), Pristina osborni (Walton, 1906), Rhyacodrilus subterraneus Hrabě, 1963, Aulodrilus limnobius Bretscher, 1899, and Aulodrilus pigueti Kowalewski, 1914 in the Czech Republic are presented. Their ecology, morphology, and distribution are discussed.

AbstractSynura lapponica Skuja, a freshwater colonial flagellate (Synurophyceae, Stramenopila), has been reported for the first time in the Czech Republic. This study evaluates the ecological requirements of the species, and includes a survey of the literature. Although S. lapponica has been reported thus far only in the Northern Hemisphere, the probability of its bipolar distribution is relatively high (22%). Distribution is probably ecologically determined, water temperature (correlated with latitude or seasonal fluctuations), and lower pH seem to be the primary environmental variables. A local vs. global ratio reflects, to a certain extent, the degree of sampling effort expended in the studied area, but a considerable increase in the number of revealed taxa was apparent when the area was expanded.
