A new species of melandryid beetle, Melandrya (Emmesa) jaromiri sp. nov., is described and illustrated. One female was found in Guanmenshan, Hubei Province, China.

Records of six species of the family Drosophilidae from the Czech Republic are presented. Drosophila tripunctata Loew, 1862, reported from the Old World long ago on the basis of a wrong determination, is newly confirmed from the region (Czech Republic: Bohemia); although this finding originates from a greenhouse, the record is important because this thermotolerant species has a potential to spread outdoors in Central Europe. Cacoxenus indagator Loew, 1858 is for the first time recorded from North Moravia (Czech Silesia) in the Czech Republic and Cacoxenus argyreator Frey, 1932 from Slovakia. Mycodrosophila poecilogastra (Loew, 1874) is new addition to the fauna of Bohemia, Drosophila (Sophophora) helvetica Burla, 1948 and Drosophila (Sophophora) suzukii (Matsumura, 1931) are new for Moravia.

The paper presents a new locality of Typha shuttleworthii W.D.J. Koch & Sond. in Poland. The species was found in wet roadside ditch in Kryg village near Gorlice (ATPOL grid square EG09). The distribution map of the species in Poland is provided.

Primary collecting data are given for 11 species of Limoniidae and Tipulidae, representing the first records from Bohemia or Moravia.

Carex pediformis C. A. Meyer is a component of dry grasslands (Festucetalia valesiacae order). It is very rare and red-listed in Poland. To date the species is know from less than ten localities in Poland of which four are currently confirmed. The paper presents a data on new locality of the species in the Central Poland (Malopolska Upland), together with remarks on its population size and habitat requirements. The distribution map of the species in Poland is also presented.

A historical survey was compiled of Rook (Corvus frugilegus) rookeries in the Moravian- Silesian region based on literature and private data covering period 1945-2015. Altogether, eighteen rookeries have been documented. During the second half of the 20 century the numbers of the Rook population in the Czech Silesia increased slowly from zero to ca. 500 breeding pairs, but the number of rookeries has decreased at the latest after 1990. Since 2000, probably only two local Rook's breeding sites exist in the town of Opava and Ostrava and only Rook's population inhabits Opava seem to be stable. It cannot be excluded that the extinction of the Silesian rookeries in the 1990s is a temporary phenomenon, whose consequence will be a further increase in the mean rookery size in town of Opava.

Five chironomid species: Thienemannimyia vitellina (Kieffer, 1916), Orthocladius (Pogonocladius) consobrinus (Holmgren, 1869), Parachironomus danicus, Lehmann 1970, Tanytarsus norvegicus (Kieffer 1924) and Tanytarus smolandicus, Brundin 1947 were recorded in Slovakia for the first time. The pupal exuviae were collected in 2012-2013 from 9 water reservoirs. Details on finding with the notes on distribution and ecology are presented.

The paper presents distributional data for 24 liverwort and 94 moss species collected at the Wiśnickie Foothills, including 26 protected and 5 threatened bryophytes

New records of Anisopodidae, Bibionidae, Cecidomyiidae, Keroplatidae and Mycetophilidae (Diptera) are presented from Muránska planina National Park (Slovakia) and the Czech Republic. The material was obtained mainly in the years 2009-2015 by means of Malaise traps and individual collecting. Three species are new to the Czech Republic, 1 to Bohemia, 3 to Moravia & Silesia and 10 to Slovakia. Several additional rare species are also recorded although they do not represent additions to the local faunas.

Althogether 17 species of the family Anthomyiidae (Diptera) are recorded from the Czech Republic (or Moravia and Bohemia) (16 species) and Slovakia (1 species) for the first time. The most interesting findings are Delia dovreensis Ringdahl 1954 and northamerican species Pegomyia bifurcata Griffiths 1983.

Results of phytosociological studies conducted in the southern part of Opole Silesia within the Sudetes mountain range in 2014-2015 are presented. The main aim of our research was to confirm the occurrence of Viscario vulgaris-Quercetum petraeae Stöcker 1965, which had previously been noted in Poland only within the Central Sudetes Foothills in Lower Silesia province. Two additional sites of this extremely rare in Poland plant association were confirmed, located within the Opawskie Mts in Opole province. The association develops on steep slopes, near rocky outcrops, on southern or western expositions at altitudes between 350 and 410 m a.s.l. All plots of the association consists of several diagnostic taxa and the share of thermophilous plants is clear. The Viscario vulgaris-Quercetum petraeae is rather species poor forest phytocoenosis with the herb layer abundance shrink by a scree downslides. The most frequent taxa contributing to the sampled plots were: Luzula luzuloides, Galeopsis ladanum, Hieracium laevigatum, Lembotropis nigricans, Vaccinium myrtillus, Deschampsia flexuosa and Viscaria vulgaris. In all forest plots the Quercus petraea apparently dominates and shrub layer is scarce.

Based on available molecular and morphological evidence, the genus Codriophorus P.Beauv. (Grimmiaceae subfam. Racomitrioideae) proved to be a polyphyletic taxon. It consists of two distinct genera which correspond to two sections of Codriophorus, namely sect. Codriophorus and sect. Fascicularia (Bednarek-Ochyra) Bednarek-Ochyra & Ochyra. The latter section is raised to generic rank as Dilutineuron Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek. The new genus consists of the following five species: D. fasciculare (Hedw.) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov., D. brevisetum (Lindb.) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov., D. anomodontoides (Cardot) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov., D. corrugatum (Bednarek-Ochyra) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov. and D. laevigatum (Mitt.) Bednarek-Ochyra, Sawicki, Ochyra, Szczecińska & Plášek, comb. nov.

The traditionally conceived genera Orthotrichum Hedw. and Ulota F.Weber are here reclassified into six genera, Orthotrichum, Dorcadion Lindb., Nyholmiella Holmen & E.Warncke, Pulvigera Plášek, Sawicki & Ochyra, Plenogemma Plášek, Sawicki & Ochyra, and Ulota, based on morphological differences and partially on molecular evidence. The genus Pulvigera includes P. lyellii (Hook. & Taylor) Plášek, Sawicki & Ochyra (Orthotrichum lyellii Hook. & Taylor) which was selected as its generitype. The genus Plenogemma includes P. phyllantha (Brid.) Plášek, Sawicki & Ochyra (Ulota phyllantha Brid.) which was selected as its generitype.

The European EMERGE (European Mountain lake Ecosystems: Regionalisation, diaGnostic & socio-economic Evaluation) project was a survey of high mountain lakes (above treeline) across Europe using unified methods of sampling and analysis. The sampling was carried out in summer or autumn 2000, and comprised biological samples, and samples for chemical analysis. Data from three lake districts are used in this paper: the Tatra Mts. in Slovakia and Poland (45 lakes), the Alps in Tyrol in Austria (22 lakes), and Scotland (30 lakes). As it is shown by multiple regression analysis, DTOC (dissolved or total organic carbon) is the key variable for most groups of zooplankton. With increasing DTOC and mostly with chlorophyll-a decreasing, pH increasing and depth decreasing, macrofitrators with coarse filter meshes are replaced by microfiltrators with fine filter meshes. Higher DTOC may increase bacterioplankton production and advantage species able to consume bacteria (microfiltrators). Other zooplankton species also differ in their preference for DTOC, chlorophyll-a, pH and depth, but DTOC being positively correlated with chlorophyll-a and pH positively correlated with depth. It may be caused by their different preference for food quality in terms of C:P ratio.
