Abstract Questions Multiple potential natural vegetation ( MPNV ) is a framework for the probabilistic and multilayer representation of potential vegetation in an area. How can an MPNV model be implemented and synthesized for the full range of vegetation types across a large spatial domain such as a country? What additional ecological and practical information can be gained compared to traditional potential natural vegetation ( PNV ) estimates? Location Hungary. Methods MPNV was estimated by modelling the ...

The survey results of the MÉTA program are managed with centralised relational database management system (MS SQL 2000) developed and set up in a local area network. Besides the MÉTA database server, a publishing server, an archiving server and a GIS workstation were applied. The core information entities of the MÉTA database are: information subproject, MÉTA quadrate, MÉTA hexagon, (semi-)natural habitat, potential vegetation with numerous habitats, landscape ecology and land use attributes, and ...

The aim of our study was to investigate if compositional (tree species richness) and structural (vertical structure, age-structure, patterns of canopy closure) heterogeneity of the canopy layer is related to individual naturalness criteria and to overall forest naturalness at the stand scale. The naturalness values of the assessed criteria (tree species composition, tree stand structure, species composition and structure of shrub layer and forest floor vegetation, dead wood, effects of game, site characteristics) ...

Despite deforestation taking place globally, forest cover is increasing in many European landscapes. This increase, however, resulting from plantations and spontaneous forest regrowth, may obscure the generally declining trend of semi-natural forests, though the latter are essential for local and landscape-level conservation strategies and sustainable forest management. We assessed changes in semi-natural and secondary forest cover since the 18th century in Hungary, focusing on the continuity of ...

SummaryThe effect of 60Co γ irradiation on the activity of valyl-tRNA synthetase isolated from chick embryo brain was studied. The enzyme activity exponentially decreased in the dose range 10–200 krad. The first step of the enzyme action, i.e. the amino acid activation, was found to be less sensitive to irradiation than the whole reaction, the formation of valyl-tRNA. 2-Mercapto ethanol and/or glycerol had a significant radioprotective effect. The lesion caused by radiation in the enzyme was also ...

Dry oak forests have one of the richest understory vegetation in Europe, but the environmental drivers of this community have been scarcely revealed. In this study, we assessed whether the amount of light, soil pH or stand heterogeneity affect primarily the species composition of this community. We investigaed 332 sampling plots in 40-165 year old managed and abandoned Quercus cerris and Q. petraea dominated forests in North Hungary. Presence-absence data of herbaceous species and seedlings of woody ...

Large herbivores have a keystone role in many forest ecosystems. There is widespread recognition that undesirable changes may be caused by the complete removal of grazing-related disturbances, whereas there can be benefits from properly managed, targeted livestock grazing, both from a forest management and biodiversity perspectives. However, there are also many contradictory statements and results about forest grazing. We summarize the main scientific evidence and knowledge gaps on forest livestock ...
