A modern classification of pastures in Karakalpak Ustyurt has been developed, which combines 7 pasture types (Anabasis salsa, Salsola arbusculiformis-Anabasis Artemisia terrae-albae-Anabasis Haloxylon ammodendron, Tamarix hispida-T. elongata, Kalidium caspicum, Halocnemum strobilaceum), 2 classes (pastures stratal plains on gray-brown soils and drainless depressions solonchaks) 42 varieties, a ...

Morphological studies and phylogenetic analyses of DNA sequences from the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of the large exon of tef1 (LEtef1) were used to investigate the taxonomy and systematics of nine Hypocrea species with anamorphs assignable to Trichoderma sect. Hyp...

The purpose of this article is to illustrate the concept of the NetAcademy for the design and implementation of online learning communities as collaborative learning environments. This paper describes the concept and realization of the NetAcademy platform dealing with its component-based design based on the media concept. After explaining the motivation of the research as an introduction in the...

The long-recognized genus Gaura was shown recently to be deeply nested within one of two major clades of Oenothera. New molecular data indicate further taxonomic changes are necessary in Oenothera sect. Gaura. We make these changes here, including three new combinations, in advance of the Onagraceae treatment for the Flora of North America. The new phylogenetic studies show that several pairs o...

Reymonta 4, 30-059 Kraków, Poland Laboratoire associé au CNRS. whether this finding does not reflect a deficiency of the simulation set-up. As it is an important question, we have decided to check it in more detail. The result of this investigation is presented in sect. 2 of this communication. In sect. 3 we also present some ...

Seven species of Marasmius sect. Globulares with smooth pileipellis cells (sect. Globulares s. Singer) have been collected in the Republic of Korea (South Korea) to date, viz. M. aurantioferrugineus, M. brunneospermus, M. maximus, M. nivicola, M. purpureostriatus, M. wynneae and M. fusicystidiosus. Descriptions of their macro- and microscopic features with a discussion of similar taxa are given...

Christiansen & Chater (C&C)'s key premise is that "if linguistic information is not processed rapidly, that information is lost for good" (sect. 1, para. 1). From this "Now-or-Never bottleneck" (NNB), C&C derive "wide-reaching and fundamental implications for language processing, acquisition and change as well as for the structure of language itself" (sect. 2, para. 10). We question both the pr...
