THE DISTRIBUTION OF CHARACTER SPECIES OF THE ISOËTO-NANOJUNCETEA CLASS IN POLAND. PART 4. LIMOSELLA AQUATICA, CYPERUS FUSCUS AND JUNCUS CAPITATUS.

Abstract: Distribution maps for Limosella aquatica L., Cyperus fucus L. and Juncus capitatus Weigel. based on all accessible data were made and are discussed. Brief descriptions of their habitats and general distributions are also given. Nowadays these species are classified as endangered. The disappearance and transformation of habitats is presumably the main reason for their absence in some areas of Poland.

EPILITHIC LICHENS ON SERPENTINITE ROCKS IN POLAND.

Abstract: A list of 84 lichen species occurring on serpentinites in Lower Silesia (southwestern Poland) is presented. The studied lichen flora is relatively poor, due to the mineralogical and chemical properties of the serpentinic substrate, together with the artificial character of most of the exposures (quarries). No exclusive serpentinophytes were found. The lichen flora is composed mainly of species characteristic for neutral or slightly alkaline siliceous rocks, together with basi- and calciphilous taxa and some species typical for mineral- and metal-enriched substrates. One of them, Catillaria atomarioides (Müll. Arg.) Kilias, is recorded for the first time from Poland.

DIGITALI PURPUREAE-EPILOBIETUM IN THE CZECH REPUBLIC.

Abstract: The natural occurrence of the (Sub)Atlantic species Digitalis purpurea in the Czech Republic was analyzed and the results of studies of the association Digitali purpureae-Epilobietum summarized. Digitalis purpurea is an alien species of Czech flora, invading mainly in western and northern Bohemia, more or less influenced by Sub-Atlantic climate. Although Digitali purpureae-Epilobietum is a typical vegetation unit of the (Atlantic-)Sub-Atlantic area of Europe, the stands analyzed in the Czech Republic can be included in this unit in terms of their floristic composition. In this association, two subassociations have been distinguished and characterized in the Czech Republic: Digitali-Epilobietum juncetosum Oberdorfer 1978 with the differential species Juncus effusus, Agrostis stolonifera, Carex brizoides, C. canescens, C. remota, Cirsium palustre, Deschampsia cespitosa, Equisetum sylvaticum; and D.-E. typicum Oberdorfer 1978. They are characterized by their structure and floristic composition, ecology and distribution.

ON THE ECOLOGY OF SORBUS AUCUPARIA (ROSACEAE) WITH SPECIAL REGARD TO GERMINATION, ESTABLISHMENT AND GROWTH.

Abstract: Sorbus aucuparia L. is a short-lived tree species very common throughout Europe, often occurring as a pioneer tree in open habitats as well as forest. Its life history traits are discussed on the basis of a case study in the Solling Mts (northwest Germany), with special regard to germination, establishment and growth. Investigations covered an old-growth spruce stand and a birch-rowan pioneer forest, the latter having developed spontaneously after storm damage in 1982. To emphasize the specific character of S. aucuparia among short-lived tree species it is compared with Betula pendula Roth, a short-lived tree species also very common in Europe, which is well studied biologically and ecologically. In its early life history, rowan should be considered a very shade-tolerant tree species, able to germinate in old-growth spruce forests under poor light and on thick layers of raw humus. There is no evidence that germination of rowan is slowed down or impeded by dense cover of Deschampsia flexuosa (L.) Trin. For birch the most suitable site conditions for germination and establishment are provided by moist sites with high relative light intensities and naturally or anthropogenously loosened topsoil layers. Once established, rowan is able to build up a ramet bank through a `guerrilla' type of clonal growth in the organic layer and can thus successfully penetrate into closed vegetation cover. Whereas rowan acts as a `stress-tolerant competitor' in its early life history, birch tends to have a more ruderal strategy by very successfully colonizing severely disturbed habitats and growing rapidly.

Key words: Sorbus aucuparia, Betula pendula, clonal growth, forest regeneration, pioneer trees, short-lived tree species

PEDICULARIS OEDERI (SCROPHULARIACEAE) IN THE CHORNOHORA MTS (UKRAINIAN CARPATHIANS): DISTRIBUTION, BIOLOGY, ECOLOGY AND THREAT.

Abstract: Ten localities of Pedicularis oederi Vahl from the Chornohora Mts (Ukrainian Carpathians) are described and mapped. They represent the only remaining metapopulation of the species in the region. The life history and population parameters of the species are depicted, and habitat characteristics are given. Grazing is regarded as the main threat to the species. It should be considered endangered. The most effective way to protect P. oederi and a number of other endangered species is to incorporate the Brebeneskul Mt. massif into the core zones of two reserves which share that area.

Key words: Pedicularis oederi, population, life history, endangered species, conservation, Carpathians

NORWAY SPRUCE REGENERATION ON DECAYING LOGS IN SUBALPINE FORESTS IN THE TATRA NATIONAL PARK.

Abstract: This study reports temporal patterns of availability of coarse woody debris on the forest floor and its influence on spruce regeneration in subalpine spruce forests in the Tatra Mts. The volume and area of all logs and stumps were measured on four study plots with a total area of 1.432 ha. Spruce regeneration on decaying logs was counted and grouped in age classes. Samples of dead logs were cross-dated to examine the decomposition rate in the climatic conditions of the upper montane belt in the Tatra Mts. On average the total volume of logs was 93 m3 ha-1 and constituted 22% of the stem volume of living trees. Logs and stumps covered 4% of the forest floor, occupying a total of 422 m2 ha-1. These values are comparable to those of similar natural spruce forests in the Carpathians and Scandinavia. On each studied plot the portions of wood belonging to each of 8 stages were determined; they seem to indicate a fairly constant supply of dead wood to the forest floor, and to confirm the old-growth status of the forest. The oldest cross-dated log came from a spruce tree that stopped growing in 1883. This suggests that the time needed for complete decomposition is relatively high, exceeding 100 years. The best substrate for spruce regeneration consisted in the most decomposed logs (stages 7 and 8), with over 1000 spruce saplings per 100 m2 log surface. Fresh logs in decay stages 1 to 3 did not provide good conditions for germination and survival of seedlings. Spruce regeneration appears on mid-decomposed logs (stages 4 to 6) about 40 years after tree death.
