Studies of the beeches and beech woods of eastern central Europe revealed, that in the postglacial period not only Fagus sylvatica (L.) emend. reimmigrated from the refugial territories in the SE-as has generally been accepted, but also the transitional taxa, which originated from hybrids with F. orientalis Lipsky. The NW area limit of these intermediate taxa must be revised. The presence in central Europe of these taxa-which form own Fagion alliances and associations in the SE (Fagus intermedia ssp. moesiaca and ssp. taurica) as well as the presence of other southeastern species in central European beach woods shows, that their postglacial development is parallel to, but different from other areas. The taxon Fagus intermedia (ssp. neglecta and ssp. transitus) became differential taxa of a central European region of the Fagion medioeuropaeum. Plant sociologists are therefore requested to make new and critical analyses of the beech woods in Europe, with special attention to the Fagus taxa, in order to establish in detail the geographical distribution and phytosociological significance of Fagus intermedia.The author offers to determine or revise Fagus material (herbarium collections).

Summary The presence of secondary sensory cells in the Octopus gravity receptor system has been demonstrated. In serial thin sections of the receptor cells (hair cells) no axons were found leaving the cells. Instead, synapses were observed with synaptic vesicles lying inside the receptor cells. Both data clearly indicate that the receptor hair cells represent secondary sensory cells. In addition, efferent contacts to the receptor cells could be confirmed.This work was supported in part by grant Wo 160/5 of the Deutsche Forschungsgemeinschaft to Prof. Dr. H.G. WolffThe experimental work was done in part at the Zoological Station in Naples and at the Sechenov Institute of Evolutionary Physiology and Biochemistry of the USSR Academy of Sciences (Laboratory of Prof. Dr. Ya.A. Vinnikov), Leningrad, USSR. The authors thank Prof. Vinnikov and Dr. Tsirulis for stimulating discussions  相似文献

Multiple discriminant analysis is a useful multivariate technique in vegetation studies that can be employed for several purposes, even if the underlying statistical assumptions are not satisfied. An example of application of this method is discussed: multiple discriminant analysis was successfully used for evaluating the predictivity of forest types defined by numerical classification of vegetation data with respect to soil variables.Species nomenclature follows Pignatti (1982) for vascular plants and Augier (1966) for mosses.The research has been supported by the IDROSER (Bologna, Italy) and by the Italian C. N. R. (Grant no. 83.02548.04, resp. Prof. A. Pirola). We wish to thank Prof. E. Feoli, Prof. E. van der Maarel, Prof. L. Orlóci and Prof. A. Pirola for suggestions. We are also indebted to Dr N. Filippi who analyzed the soil samples.  相似文献

Summary Frequencies of the dibucaine resistant variant of pseudocholinesterase and of the electrophoretic C5 + component have been investigated in a sample of 992 Finnish Lapps and 317 Finns. Skolt Lapps show distinctly higher values than the other Lapps and Finns of this area. The lowest frequency of the C5 + component has been found in Finns. The frequencies found in the various population groups of this study fit well into the range reported for the human populations studied so far.Direktor: Prof. Dr. W. LehmannDirektor: Prof. Dr. H. W.

The tubular spermatophore of Gomphocerus rufus L. is formed 3 to 4 minutes after the begin of copulation; it consists of various proteins which are secreted by the 16 tubules of the paired accessory glands. Selective surgical ablation of the tubules indicate, that the secretion of the accessory glands serve the following functions: determination of the shape of the spermatophore, transmission of the pressure necessary for spermatophore transfer and formation of the lumen of the spermatophore. The course of production of the spermatophore has been studied.
