Atmospheric nitrogen deposition promotes carbon loss from peat bogs.

Series of studies (from which only one is cited here) on N deposition threatening nutrient relationships of ombrotrophic peat bogs and Sphagnum spp and the emmissions of C from these ecosystems. Due to the enhanced N deposition decomposition processes are fastened, leading to the change of the role of peat bogs from C sinks to CO2 emmission sources.

History, genetic differentiation and conservation strategies for disjunct populations of Sibbiraea species from Southeastern Europe and Asia

The study deals with the problematics of schrub species of Sibirea altaiensis, the engangered species at the upper timber line. The main thread to its existence is abandoned pasture activities in mountains. Performed genetic analysis indicates very homogeneous disjunct Dinaric populaitons and autochtonous populations in Altai. We propose measures to be taken for active protection of the species in pasture areas at the upper timber line.

Diversity of dead wood inhabiting fungi and bryophytes in semi-natural beech forests in Europe.

The influence of the distribution, decay phase and size of beech coarse woody debris on the diversity of fungi and bryophites is presented, resulting from a common european approach in the 5FW EU project NATMAN. The diversity was studied in forest reserves in Slovenia, Hungary, The Netherlands, Danmark and in Belgium. The consequences for conservation and forest management are implied.

Changes in the community of ectomycorrhizal fungi and increased fine root number under adult beech trees chronically fumigated with ...

The paper presents results of the first experimental example of chronical exposure of adult forest trees in stand to increased ambient concentration of ozone and recorded influence to ectomycorrhial community and fine roots below ground (drift in ECM community and transiensly increased number of fine roots in upper 20 cm of soil).

The climate sensitivity of Norway spruce (Picea abies (L.) Karst.) in the southeastern European Alps

The potential of Norway spruce as a palaeoclimate archive in the SE European Alps, tree ring chronologies were developed from trees growing at two sites in Slovenia. Maximum density responds to September temperatures, indicating lignification after cell division has ceased. Stable C isotopes respond strongly to summer temperature in alpine and lowland stands. Height increment appears relatively insensitive to climate and is dominated by local stand dynamics.
