DasCladonio rangiferinae-Pinetum sylvestris des Landschaftsschutzgebietes Křivoklátsko (Mittelböhmen) und seine Stellung im phytozönologischen System
The pine forest with an undergrowth of fruticose lichens—Cladonio rangiferinae-Pinetum sylvestris (Kobenza 1930) em.Passarge 1956 from the protected landscape area KřizoklätsCladonio-Pinetum comprises a permanent pine forest community occurring naturally on a hard base and nutrient deficient siliceous rocks in the semiconvex parts of the steep slopes of narrow side-valleys of the Berounka river. The soil type of this community is dystrophic ranker. The phytosociological composition of theCladonio-Pinetum is documented by the table of relevés, the habitat by chemical analyses of the soil.
Zur Syntaxonomie desDeschampsio flexuosae-AbietetumHusová 1968
Based on new relevés from the area of the Czech Socialist Republic, the associationDeschampsio flexuosae-AbietetumHusová 1968 is divided into two subassociations:D.f.-A. deschampsietosum flexuosae andD.f.-A. calamagrostietosum. The species composition and variability of the association and both subassociations is given in a synoptic table. The soil properties are also added.
The first ground cricket (Orthoptera: Trigonidiidae: Nemobiinae) from mid-Cretaceous Burmese amber
Abstract A new genus and species, Birmaninemobius hirsutus gen. et sp. nov., is described on the basis of a well-preserved orthopteran specimen in mid-Cretaceous Burmese amber and attributed to the subfamily Nemobiinae (ground crickets) of the family Trigonidiidae (Grylloidea). As the first record of Nemobiinae from mid-Cretaceous Burmese amber, this new taxon not only provides novel morphological diversity in ground crickets but also indicates that the ground crickets lived in Burma (Tethyan islands) as early as the mid-Cretaceous.
