„Velké druhy“ racků je označení zahrnující racky z druhového komplexu racka bělohlavého (Larus cachinnans), racka středomořského (L. michahelis) a racka stříbřitého (L. argentatus). Jejich populace v Evropě a Severní Americe za posledních ca 50 let značně narostly. Šíření tak oportunistických druhů vyvolalo obavy z jejich možného negativního vlivu na biodiverzitu, početnost a hnízdní úspěšnost jiných druhů vodního ptactva. Naskýtá se otázka, zda je vhodné začít velké druhy racků na našem území potlačovat, a pokud ano, jaká opatření by bylo vhodné zavést., The populations of „large gulls“ from the species complex Larus cachinnans, L. michahelis and L. argentatus have undergone a widespread demographic increase in the last 50 years, particularly in Europe and North America. The spread of such opportunistic species can negatively influence biodiversity and the breeding success of other bird species breeding at the same site. The question of population control and different methods used is nowadays also a frequently discussed topic in the Czech and Slovak Republics., and Hana Latková.

The tradition of International Congresses of Historical Sciences started in 1900. Except during the World War I and World War II, it has been held 21 times so far. Being the most influential academic activity of historical sciences, it enjoys a reputation of the “Olympics of Historical Sciences”. From 23 to 29 August, 2015, the 22nd ICHS was held in Jinan, China. It was the first time for the Congress to be held in Asia. The event, hosted by the International Committee of Historical Sciences, was organized by the Association of Chinese Historians and Shandong University.

Zástupci rodu Compsopogon (Rhodophyta) jsou tropické druhy řas. Ve střední Evropě se nacházejí v akváriích a v tocích, ovlivněných vypouštěním oteplených odpadních vod. Druh Compsopogon aeruginosus byl nalezen v rakouském přítoku řeky Dyje Pulkavě. Od prvního nálezu v roce 2007 se tato ruducha šířila i do řeky Dyje. V červnu 2012 byla nalezena ve Skryjském potoce, který přivádí odpadní vody z jaderné elektrárny Dukovany. Odpadní voda v době nálezu měla průměrnou roční teplotu 22,8°C, pH 8,5., The representatives of the genus Compsopogon (Rhodophyta) are basically tropical algae. In Central Europe, they are only found in aquaria and in water bodies affected by thermal effluents. The species Compsopogon aeruginosus was found in the Pulkau River (Austria), a tributary of the Thaya. After the first observation of this species in 2007, it also expanded to the Thaya. In June 2012 it was found in the Skryjský stream which is fed waste water from the Dukovany nuclear power station. At the time of this finding, the waste water had an annual average temperature of 22.8°C, pH 8.5., and Pavel Sedláček, Zdeňka Žáková, Hana Mlejnková.
