In this issue, we bring you an essay on the International Year of Biodiversity, a year-long celebration of biological diversity and its value for life on Earth, taking place around the world during 2010. This observance is intended, through activities and events in many countries, to help raise awareness of the importance of biodiversity. and Jiří Sádlo.
In November 2009, the United Nations declared 2010 to be the International Year of Biodiversity. It has been a celebration of life on earth and of the value of biodiversity for our lives. The world has been invited to take action in 2010 to safeguard biodiversity, i. e., the variety of life on earth. Throughout the year countless initiatives were organized to disseminate information, promote the protection of biodiversity and encourage organizations, institutions, companies and individuals to take direct action to reduce the constant loss of biological diversity worldwide. and Petr Petřík.
V tomto článku podáváme syntézu poznatků komplexního výzkumu lučních prameništních slatinišť Západních Karpat, kde od r. 2010 intenzivně zkoumáme také vodní bezobratlé. Zjistili jsme neobvykle druhově bohatá společenstva vodního hmyzu s vysokým podílem stanovištních specialistů a s řadou druhů nových pro studované území. Z obecných ekologických zákonitostí jsme prokázali vysoký vliv chemismu vody na druhovou skladbu dvoukřídlého hmyzu (Diptera) a zcela převažující vliv lokálních faktorů na výskyt taxonů schopných aktivního letu., In this paper we summarise the results of complex research at the Western Carpathian treeless spring fens, in which we have also studied aquatic invertebrates since 2010. We found extraordinarily species-rich assemblages of aquatic insects with a high proportion of habitat specialists and many species previously unknown for the study area. Among general ecological patterns, we confirmed the high importance of water chemistry for species composition of Diptera assemblages and a prevailing role of environmental-based processes on the distribution of taxa with flying adults., and Michal Horsák ...
