Since the early 2000s, reports on declining hornbeam trees (Carpinus betulus) are spreading in Europe. Two fungi involved decline phenomenon: One is Anthostoma decipiens, but other etiological agent has not been identified yet. We examined morphology, phylogenetic position, and pathogenicity of yellow fungal isolates obtained from Austria, Georgia Switzerland, compared data with disease norther...
This paper documents data on standing dead trees (snags) in the pine-spruce (Norway spruce Picea abies, Scots pine Pinus sylvestris) natural stand in Bialowieza National Park (BNP) in northeast Poland. Trophically, this mostly coniferous stand represents one of the poorest habitats of the BNP, and this stand has never been cut. There are few tree species of significance, i.e., Scots pine, Norwa...
Understanding how past climate changes affected biodiversity is a key issue in contemporary ecology and conservation biology. These diversity changes are, however, difficult to reconstruct from paleoecological sources alone, because macrofossil and pollen records do not provide complete information about species assemblages. Ecologists therefore use information from modern analogues of past com...
