Natural enemies of bark beertle Ips typographus
Zelený, Jiří ; Lozan, Aurel
Totally 49 species of predators and 22 species of parasitoids are contributing to the population regulation of bark beetles, namely Ips typohraphus, in spruce forest of the Czech republic. The most encountered predators of bark beetles in our samples during 1998-2003 were: Thanasimus formicarius (Coleoptera), Medetera signaticornis and Lonchaea bruggueri (Diptera): hymenopteran parasitoids: Coeloides bostrichorum, Dendrosoter middendorfii, Cosmophorus klugii (Braconidae): Rhopalicus tutela, Roptrocerus xylophagorum, Tomicobia seitneri a Dinotiscus eupterus (Pteromalidae). The siricid wasp Ibalia leucospoides (Cynipoidea, Ibaliidae) is recorded too.

Bioeroze v geologickém záznamu České republiky. Exkurzní průvodce pro předkonferenční exkurzi 4. mzn. konference o bioerozi. 22.-28. srpna 2004, Česká republika
Mikuláš, Radek
Geological record of bioerosion of the Czech Republic represents a great stratigraphic range, variety of settings and diverse substrates. We have to mention microborings in the probable Late Proterozoic stromatolites, bored bioclasts of the Silurian and Devonian, Devonian and Carboniferous hardgrounds and rockgrounds, rare wood borings in the Permian deposits (Bohemian Massif), Jurassic transgressive and reef facies, Early Cretaceous rockgrounds (Carpathians), Upper Cretaceous bored rockgrounds, bioclasts and wood (Bohemian Massif), Cenozoic borings in wood, leaves, fruit stones and bones (Bohemian Massif), bioclasts and rockgrounds of the Miocene bottom and sedimentary fill of the Carpathian Foreland and the Vienna Basin. Several Pleistocene and Holocene archaeological sites contain the record of animal and plant bioerosion coupled with the human activity.

Sborník abstraktů ze 4. mezinárodní. konference o bioerozi
Forty-four international contributions on bioerosion from the fossil record and from modern settings show that the first intensively bioturbated substrates were carbonate hardgrounds, soon followed by carbonate bioclasts. By the end of Paleozoic, wood bioerosion starts to take place; marine bioerosion in lithic substrates have much diversified during the Cretaceous and Cenozoic. The set of extended abstracts also shows increasing interest on mammals as tracemakers, and on bioerosion on non-marine settings.
