<abstract xmlns="http://www.w3.org/1999/xhtml">The study summarises results of the ichthyologic research of the Podolský and Stříbrný brooks in Hrubý Jeseník. The research was organised for the purpose of finding the actual situation in the fish settlements in the sections of interest and to make suggestions for their further management benefiting the original fish communities.The results have shown that there is the community of water organisms with naturally reproducing <italic>Cottus poecilopus</italic> and <italic>Salmo trutta</italic> in both partly adjusted water flows which have not been restocked by man since 1996.The facts found within the research suggest that the biologically correct way for the further development of fish populations in the Podolský and Stříbrný brooks may be the maintenance of the existing natural conditions while no local adjustments of the flow beds along roads should be excluded.The research results have proved that the existing natural conditions and the very limited anthropogenic pressure put on the water biocenoses have been the decisive factors during the formation of the now existing fish population structures which can be assessed as good from the ecological point of view. Because of that we have recommended to the manager of the water flows neither interfering in the development of the current fish populations nor restocking any fishes.We consider the finding that the age structure and the high numbers of <italic>Salmo trutta</italic> and <italic>Cottus poecilopus</italic> have been, in the given situations, the indicators of their populations’ ability, even at the sympatric presence of <italic>Lutra lutra</italic> and <italic>Ciconia nigra</italic>, resistant against the predators’ pressure, as very important.</abstract>

New distribution records of <italic>Solidago</italic> ×<italic>niederederi</italic> (Asteraceae) in Austria, Italy, and Poland

<abstract xmlns="http://www.w3.org/1999/xhtml">Here we present first records of three moth fly species in the Czech Republic (<italic>Katamormia bezzii</italic> Salamanna, 1983, <italic>Panimerus goodi</italic> Vaillant &amp; Withers, 1992 and <italic>Pneumia fonticola</italic> (Szabó, 1960)), increasing the total number of Czech moth fly species to 179. <italic>Katamormia bezzii</italic> represents the first finding outside of Italy, while <italic>P. goodi</italic> is only the second record outside of its type locality (Ireland), as is <italic>Peripsychoda zbytka</italic> Ježek, 2004 (Bohemia or.) and <italic>Pneumia kabelaki</italic> Omelková &amp; Ježek, 2012 (Bílé Karpaty PLA). <italic>Jungiella</italic> (<italic>Psychocha</italic>) <italic>janiki</italic> Omelková &amp; Ježek, 2017 has only been found at five sites (incl. the type locality) in the Bílé Karpaty Mts so far. The current number of species from the northwest part of the Czech Carpathians now totals 116. Altogether, 32 species were included in the national Red List of threatened invertebrates (Ježek 2005), with 23 species categorised as ‘nationally scarce’. Maximum alpha diversity was 61 species (71 as the sum of two seasons) at SKM OR 1 in the Skalická Morávka National Nature Monument (NNM), with maximum beta diversity also recorded at the Skalická Morávka NNM, with 82 species from three localities.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">In 2010, an attempt was made to quantify bird species breeding in the Opava Mts. and their foothill (c. 135 km2, including c. 40 km2 [31%] of forests). The area is situated in the extreme south of Opole Silesia, SSW Poland. For most non-passerine species, total counts were made for the whole area (distribution of their breeding pairs is shown on maps), while for most passerine species, semi-quantitative studies were conducted. A total of 116 breeding and two probably breeding bird species were recorded. Changes in breeding avifauna of the area during the years 1880-2010 are also analysed based on literature search. A total of 134 breeding bird species were recorded over the 130 years. During the years 1990-2010, decreae in numbers has been evidenced for the following species: <italic>Perdix perdix, Tetrastes bonasia, Tyto alba, Athene noctua, Corvus frugilegus,</italic> and <italic>Nycifraga caryocatactes</italic>, In the same period, increase in numbers has been documented for species such as: <italic>Accipiter gentilis, Falco tinnunculus, Columba oenas, Jynx torquilla, Dryocopus martius, Picus canus, Picus viridis, Motacilla cinerea, Luscinia megarhynchos, Phoenicurus phoenicurus, Saxicola rubicola, Locustella naevia, Locustella fluviatilis, Corvus corax and Corvus cornix</italic>. Opava Mts. and its foothills constitute an imporant conservation area. Fifteen species listed in Annex I of the Bird Directive of the E.U. were recorded there, including a sizable population of <italic>Ficedula albicollis</italic>.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">A zoogeographical review summarized the current distribution of 28 morphologically determined horse fly species recently collected in three Western Africa countries. In Malaise trap collections, the family Tabanidae was represented by three subfamilies, Pangoniinae, Chrysopsinae and Tabaninae (tribes Philolichini, Chrysopsini, Tabanini and Haematopotini), and six genera: <italic>Philoliche</italic> Wiedemann, 1828 (1 species), <italic>Chrysops</italic> Meigen, 1803 (3 specis), <italic>Ancala</italic> Enderlein, 1922 (2 species), <italic>Euancala</italic> Enderlein, 1922 (1 species), <italic>Tabanus</italic> Linnaeus, 1758 (13 species) and <italic>Haematopota</italic> Meigen, 1803 (8 species). Information contained in the principal publication The Catalogue of the Diptera of the Afrotropical Region 1980 is complemented by newly published studies on horse flies in Sub-Saharan Africa.</abstract>
