The paper deals with the estimation of maximum above-ground herb-layer biomass in selected forest communities of the Malé Karpaty Mts., (Lesser Carpathians) SW. Slovakia. Use was made of a combined method of indirect sampling and phytocenological relevés, and the following values were ascertained: 41 kg/ha in theLuzulo-Fagetum (276 kg/ha if mosses included), 691 kg/ha in theCarici pilosae-Carpinetum, 364 kg/ha in theDentario-Fagetum, 476 kg/ha in theAceri-Carpinetum, and 1364 kg/ha in theStellario-Alnetum. The results are discussed and compared with earlier data published in the literature.
Beitrag zur Kenntnis desAlnetum incanae in der Tschechischen Sozialistischen Republik (ČSR)Neuhäuslová-Novotná, Zdenka

Gegenstand dieses Beitrages ist die syntaxonomisch-synökologische Charakteristik desAlnetum incanaeLüdi 1921 in den Tschechischen Ländern. Bestände dieser montanen Auenwaldassoziation begleiten hier Flussgewässer in Gebirgstälern und am Hochgebirgsrand, meist in den Lagen von 650–900 mü. NN. DasAlnetum incanae wird in zwei Subassoziationen geteilt. Das feuchteliebendeAlnetum incanae calthetosumKnapp exNeuhäuslová-Novotná subass. nova ist an Gleyböden (Nassgleye, sauerstoffreiche Gleye) gebunden, dasAlnetum incanae typicumOberd. 1949 (mit zwei Varianten)bestockt Paternia-Böden. DieAegopodium podagraria-Variante der typischen Subassoziation bevorzugt pedogenetisch mehr entwickelte Böden mit tiefem Grund-wasser, meist in der Kontaktzone zu Klimaxgesellschaften.
Palaeoecological investigations of buried peat profiles from the Zbudovská blata marshes, Southern BohemiaRybníčková, Eliška; Rybníček, Kamil; Jankovská, Vlasta

sThe authors present the results of basic stratigraphic investigation, pollen analyses and macroscopic analyses of plant remains concerning two buried peat profiles and their mineral covers in the Zbudovská blata marshes near České Budějovice (southern Bohemia, Czechoslovakia). Both profiles (JC-9-A and JC-9-B) are characterized by two phases of sedimentation—earlier organogenic (Dryas III, Pre-boreal, Boreal periods) and later minerogenic (Sub-atlantic period). A stratigraphic hiatus appears between these two phases. The palaeoecological investigation supports the existing information about the rare occurrence ofCorylus in some areas of Czechoslovakia during the Boreal period, brings proofs of fir forests in the area of the České Budějovice Basin in the early Sub-atlantic period, and yields new data on the palaeophytogeography of some aquatic, swamp and mire plants. The paper also attempts to reconstruct the succession of local peatforming communities. A comparison of the development of vegetation in the České Budějovice Basin and in the neighbouring Třeboň Basin is appended.
Two rare Japanese species of the genusAlbatrellus (Polyporaceae)Pouzar, Zdeněk

Descriptions (mainly of microstructures) are given for two Japanese species:Albatrellus cantharellus(Lloyd) Pouz. andA. yasudai(Lloyd) Pouz. The former is classified, along with other amylosporous species lacking clamps on the context hyphae, asA. subrubescens(Murrill) Pouz.A. yasudai is referred to a new separate subgenusHymenidermigerPouz. based on the hymeniform cuticle of the pileus, which is a unique character in this genus.
Net above-ground biomass and production in the monsoonal vegetation at Jodhpur, Rajasthan, IndiaHarsh, L. N.; Sen, D. N.
doi: 10.1007/bf02852866pmid: N/A
The observations on net above-ground biomass and production in a large protected area of monsoonal vegetation at Jodhpur (India) are presented in this paper. With the start of the monsoon (July–August) a distinct increase in biomass was noted and by winter (November–December), the biomass, decreased as there was hardly any moisture in the soil. The ephemerals, especially some of the grasses form the bulk of biomass in the total make-up. The biomass and production appeared to be closely related in the monsoonal vegetation of this area. The maximum biomass value (360.5 g/m2) was observed in the month of September, decreasing thereafter.
