Použití jmen mytologických postav v nomenklatuře bezobratlých živočichů je velmi rozsáhlé. Ježovky, krabi, měkkýši, červi – ti všichni často nesou jména antických mýtických bytostí, a to s odkazem na své vzezření, způsob života či oblast výskytu., The use of the names of mythological characters in the nomenclature of invertebrates is very common. Urchins, crabs, molluscs, worms – all of them often bear the names of ancient mythical beings, referring to their appearances, ways of life or habitats., and Tomáš Pavlík.
Příspěvek shrnuje dosavadní poznatky o skupině mořských bezobratlých - nohatkách (Pantopoda). Přibližuje jejich ekologii, morfologii, rozmnožování a fylogenezi. Zároveň ukazuje preparáty nohatek uložené ve sbírkách Národního muzea v Praze., This contribution summarizes the current knowledge about the sea spiders (Pantopoda). It is focused mainly on their ecology, morphology, reproduction and phylogeny. The review is also accompanied by figures of the specimens deposited in the National Museum in Prague., and Petr Dolejš.
Pokles kyselé atmosférické depozice od 90. let minulého století a rovněž postupné oteplování klimatu bylo prokazatelně doloženo i pro horské ekosystémy v nejvyšších slovenských pohořích. Výzkumy epigeické aktivity mnohonožek (Diplopoda) v letech 1992-1993, 1997-1998, 2007-2008 a pokračující sledování v současnosti svědčí o rozmanitosti společenstev těchto půdních bezobratlých včetně přítomnosti řady karpatských endemitů v závislosti na odlišném geologickém podloží (žula a vápenec) a typu vegetace. Pozorovaný ústup chladnomilných endemitů i nárůst podílu eurytopních adaptabilních druhů lze dávat do souvislosti s probíhajícími změnami v chemismu půd i změnami klimatu., The decline of acid deposition since the 1990s, together with subsequent climate warming, was confirmed also for mountain ecosystems in the highest Slovak mountains. The study of epigeic activity of millipedes (Diplopoda) in the periods 1992-93, 1997-98 and 2007-08, and continuing recent research refer to the high diversity of their communities including the presence of Carpathian endemic species on different geological bedrocks (granite and limestone) as well as different vegetation covers. The observed decline of cold tolerant endemics and the increasing portion of eurytopic species may be connected with changes in soil chemistry as well as with climate changes., and Karel Tajovský.
The winter diet of the great tit (Parus major) was examined in mixed and deciduous forest in central Slovakia during three winters. Using a faecal samples analysis, in 105 sampled roosting individuals (in nestboxes) at least 37 taxa of invertebrates were found. Apart from the invertebrates, plant material was identified in dissected birds’ droppings as well. There were no significant differences in the winter food composition between sexes. Generally, plant material was the most frequent and the most dominant winter food. This component was followed by moths, beetles and dipterans. While comparing the relative volume between two distinct habitats, the most significant difference was found in Lepidoptera adults and plant material. Birds from mixed forest foraged less on Lepidoptera adults in contrast to individuals from deciduous forest. This could be compensated by bigger consumption of seeds and buds there. Regarding seasonal changes, within five winter months (from November to March), the relative volume and frequency of some invertebrate groups (Heteroptera, Homoptera and Lepidoptera) significantly increased with the temperature but no correlations were found with other weather characteristics. Invertebrates exhibited the opposite seasonal pattern compared to the plant material.
As urbanisation is set to continue, understanding the impact on wildlife becomes increasingly important if we are to be able to conserve biodiversity. As an excellent group of bioindicators, invertebrates can allow us to understand some of the forces in urban areas which impact upon biodiversity and wildlife populations. This paper discusses some of the trends in the abundance, diversity and richness of invertebrates related to urbanisation and the specific urban environmental and traffic factors which may be at play., Elizabeth L.
