Long-term trends in vegetation changes of managed versus unmanaged Eastern Carpathian beech forests
Forest Ecology and Management, 2010Abstract A vegetation survey of semi-permanent plots was conducted between years 1955–1962 and 2005–2009, and aimed to determine floristic changes occurring in beech forests located on a scarcely populated, dense forest area. The survey encompassed all natural beech forest types within the Polish part of the “Eastern Carpathians” International ...

Genetic variability of European beech provenances from south-eastern Europe
2010This paper presents research results on the variability of height growth, annual growth, flushig phenology and winter leaf retention of European beech (Fagus sylvatica L.) in a provenance trial "Medvednica" in Croatia. The experiment was established in spring 2007 with plants 2 and 3 years of age.

Review of Palaeobotany and Palynology, 1987
Abstract Maps of Holocene changes in pollen percentages show changes in the magnitude and location of taxon abundances. They also show changes in the patterns of decreasing abundance around the areas of maximum abundance. Transport equations with source/sink, advection, and diffusion terms provide analogs for modeling these different components of ...

Some mechanical properties of eastern beech wood
2004This study determined some mechanical properties (compression, static bending, impact bending and shear strengths) of eastern beech wood (Fagus orientalis Lipsky.) and to compared them with other beeches. The materials studied were randomly selected from pure beech stands, naturally grown in Andirm-Kahramanmaraş, and these were prepared and tested ...

Research on the responses of a beech stand to extreme drought in Eastern Bakony, Hungary
In forest management, there is an outstanding importance of water cycle of the forest because of ecological and economical viewpoints, including the water management of woody plants. Examining the reactions of trees to environmental stress – warming, extreme drought or intense rains – and the phenomena derived from this, help to ...Gergely Levente Kökény +2 more

Beech bark disease (BBD) is an insect–fungus complex involving the beech scale insect ( Cryptococcus fagisuga Lind.) and one of two canker fungi. Beech scale was introduced to Halifax, Nova Scotia around 1890, presumably with the fungus Neonectria coccinea var. faginata Lohm.

We re-evaluate and clarify the syntaxonomic position of the fir-beech and spruce-fir mixed forests in Romania. The syntaxa described from the South-Eastern Carpathians are well differentiated both floristically and ecologically along gradients of soil ...
