AbstractThe distribution and ecology of desmids in wetland habitats in the Czech Republic were studied during 2003–2007. Samples were taken also from various aerophytic habitats and temporary pools thet had not been sufficiently studied before. Altogether 110 desmids taxa were found in 31 samples which were ordinated on the basis of their desmid species composition using a multivariate statistic method. The discussion focuses on the most interesting findings and on the factors that influence the distribution of desmids in different types of aerophytic habitats.

Contributions to the distribution and ecology ofCarex hordeistichosVill. in the Czech Republic and SlovakiaCurrent and historical occurrence as well as habitat requirements ofCarex hordeistichosin the Czech Republic and Slovakia are presented. The study is based on the revision of herbarium specimens from 25 herbaria and a field survey carried out during 2004-2009. Altogether, 195 sites were documented in the Czech Republic, exclusively in the Moravia region. Recent occurrence was confirmed at only four localities (2% of sites), therefore the status of threat was confirmed - the species is critically endangered. In Slovakia, 184 localities of the species were recorded in total; 34 sites were found in period 1975-1999 and 35 sites were confirmed recently (19% of sites recorded), but only 6 in the Pannonia (3% of sites). The number of localities was stable over the last 35 years, therefore, we re-evaluated the IUCN status ofC. hordeistichosin Slovakia. The species is now assessed in the category vulnerable - VU. Results of the study are summarised in the maps of historical and actual species distribution.C. hordeistichosusually occurred in various wet grassland communities and it had no well-defined coenotic relationships. On the basis of our knowledge, we considerC. hordeistichosas a facultative halophyte.

Abstract Six chironomid species: Paraboreochlus minutissimus (Strobl, 1894), Trissopelopia longimanus (Staeger 1839), Boreoheptagyia monticola (Serra-Tosio, 1964), Cricotopus (s.str.) similis Goetghebuer 1921, Heleniella serratosioi Ringe, 1976, Krenosmittia camptophleps (Edwards, 1929), were recorded in Czech Republic for the first time. The pupal exuviae were collected in July 2009 from Otava River in the vicinity of Rejštejn village in the central part of the Bohemian Forest. The notes on known distribution and ecology of the species are presented.

Current and historical occurrence as well as coenotic affinity and ecology of <em>Carex secalina </em>in the Czech Republic and Slovakia are presented. The study is based on revision of herbarium specimens from 25 herbaria, literature data excerption and a field survey carried out during 2004-2010. Altogether, 168 sites were documented in the Czech Republic divided to two separate areas. Stabile occurrence trend was found in last decades, because 45 localities were documented in period 1975-1999 (27% of sites) and recent occurrence was confirmed at 42 localities (24% of sites). On the basis of our current knowledge the species was included into the IUCN threat category VU (vulnerable). In Slovakia, 19 localities of the species were recorded in total, but only 4 sites were confirmed recently (21% of sites recorded). However, only a small number of individuals was recorded there (less than 50 individuals in total) and half of this sites is acutely threatened by destruction (ploughing, secondary succession). Therefore, the <em>C. secalina </em>status in the Slovak Red List was changed to the IUCN category "critically endangered" (CR). Results of the study are summarised in the maps of historical and current species distribution. <em>C. secalina </em>usually occurred in halophytic grassland communities, especially in association <em>Agrostio stoloniferae-Juncetum ranarii </em>Vicherek 1962. However, it may occur in many other communities which suggest that the species had not well-defined coenotic relationships. On the basis of our knowledge, we consider <em>C. secalina </em>as an obligate halophyte.
