During a bryofloristical investigation in the vicinity of Ómassa (Miskolc) in the Bükk Mountains (NE Hungary), three montane-boreal bryophyte species new to the Hungarian bryoflora were collected. Encalypta spathulata Müll.Hal. was found on the ledges of limestone cliffs of Vörös-kő Hill as well as on the rocky debris among roots of a fallen tree l...

To secure the ecosystem services forests provide, it is important to understand how different management practices impact various components of these ecosystems. We aimed to uncover how silvicultural treatments affected the ground-dwelling spider communities during the first five years of a forest ecological experiment. In an oak-hornbeam forest st...

Hybridization associated with polyploidization and apomixis is a frequent mechanism of speciation. Sorbus is a genus with ongoing hybridization resulting in a polyploid complex with different parental lineage. Triparens is the smallest hybridogenous subgenus of Sorbus so far known to comprise only two taxa, S. intermedia and S. × liljeforsii that c...

Aim Dead wood inhabiting bryophyte communities are formed by several important factors. Besides the amount, quality and continuity of the substrate, there are also external factors indirectly influencing their structure. One of the most important is local microclimate. This fact has been recognized by many previous authors, yet studies exploring th...

There is a paradigm shift in silviculture towards the not just economically but also ecologically sustainable continuous cover forestry (CCF) methods. Their aims are to provide timber, to maintain buffered microclimate and biodiversity, and to meet social requirements simultaneously. However, the concept and the details of these techniques has to d...

Stable below‐canopy microclimate of forests is essential for their biodiversity and ecosystem functionality. Forest management necessarily modifies the buffering capacity of woodlands. However, the specific effects of different forestry treatments on site conditions, the temporal recovery after the harvests and the reason of the contrasts between t...

Forest-grassland mosaics are widespread features at the interface between tree- and grass-dominated ecosystems. However, the importance of habitat heterogeneity in these mosaics is not fully appreciated, and the contribution of individual woody and herbaceous habitats to the overall conservation value of the mosaic is unclear. We distinguished six...

Forest management alters forest site; however, information is still limited about how different silvicultural treatments modify abiotic conditions. We compared the effects of four treatments from three different forestry systems on forest microclimate, litter, and soil conditions. The clear-cutting, retention tree group, preparation cutting, and ga...

Conference Paper
Due to their diminutive appearance, often microscopic size, special habitat and characteristically winter seasonality bryophilous fungi belong to the underrecorded groups of fungi. During field trips and the study of bryophyte herbaria about 500 occurrences of forty six obligate bryophilous fungi were detected in Hungary. Most of them are represent...

The Hungarian Red Data Book (NÉMETH 1989) represents the threatened vascular plants of Hungary; however, it was published nearly 20 years ago. To date, our know-ledge is greatly broadened on the flora of the country, so the former Red List is already obsolete. The authors have elaborated a new variant of the Red List of the threatened Hungarian vas...

The genus Buxbaumia includes two species (Buxbaumia aphylla and B. viridis) in Hungary. Both of them were thought to be rare and threatened: B. aphylla was rated as Vulnerable (VU), while B. viridis as Endangered (EN) on the national Red List. The aims of the research are to summarize the historical and actual distribution of these taxa and to reveal their habitat preference, population size, ecology and phenology in Hungary.
