Grasslands of middle mountain regions are among the most diverse habitats of the Carpathian Basin, but they are threatened by spontaneous succession leading to woody encroachment. It is a high priority of nature conservation to preserve these diverse habitats by suppressing the woody encroachment and to create new open habitat patches by scrub removal. The main goal of this study was to investigate the effect of shrub cover on plant species composition and vegetation in...

Single and mixed arbuscular mycorrhizal fungal species inocula have a different effect on the growth and oxidative stress defense in Lolium perenne exposed to phenol and polynuclear aromatic hydrocarbons

Monika Malicka, Franco Magurno, Posta Katalin, Damian Chmura & Zofia Piotrowska-Seget
Arbuscular mycorrhizal fungi (AMF) are ubiquitous mutualistic plant symbionts which promote plant growth and protect them from abiotic stresses. Studies on AMF-assisted phytoremediation have shown that AMF can increase plant tolerance to the presence of hydrocarbon contaminants by improving plant nutrition status and mitigating oxidative stress. This work aimed to evaluate the impact of single-species or mixed-species AMF inocula, obtained from the contaminated environment (Funneliformis caledonium, Diversispora varaderana, Claroideoglomus walkeri), on a growth, oxidative stress...

Inconsistent effects of agricultural practices on soil fungal communities across twelve European long‐term experiments

S. Emilia Hannula, D. P. Di Lonardo, B. T. Christensen, F.V. Crotty, A. Elsen, P.J. Erp, E.M. Hansen, G. H. Rubæk, M. Tits, Z. Toth & A. J. Termorshuizen
Cropping practices have a great potential to improve soil quality through changes in soil biota. Yet the effects of these soil improving cropping systems on soil fungal communities are not well known. Here, we analysed soil fungal communities using standardized measurements in 12 long‐term experiments and 20 agricultural treatments across Europe. We were interested in whether the same practices (i.e. tillage, fertilization, organic amendments and cover crops) applied across different sites have predictable and repeatable...

One year of conservation management is not sufficient for increasing the conservation value of abandoned fen meadows

Judit Bódis, Bence Fülöp, Vivien Lábadi, András Mészáros, Bálint Pacsai, Petra Svajda, Orsolya Valkó & András Kelemen
In Central Europe many grasslands are threatened by the abandonment of traditional land use, lead- ing to litter accumulation and encroachment of competitive grasses, woody and invasive species, ulti- mately causing the loss of biodiversity in the long run. Resumption of traditional management practices might reverse the negative effects of abandonment, but can be challenging in the current socio- economic context, especially in habitats providing poor-quality forage, such as fen meadows. Given the limited resources...

Long-term results of initial seeding, mowing and carbon amendment on the restoration of Pannonian sand grassland on old fields

Yesenia Belén Llumiquinga, Bruna Reis, Nora Saradi, Katalin Török, Katalin Szitár & Melinda Halassy
Cropland abandonment is an opportunity for semi-natural biodiverse ecosystems to develop through spontaneous succession or active restoration. Spontaneous recovery is limited by the dispersal and capacity of species to establish under the given environmental circumstances. This paper provides an evaluation of three restoration techniques to overcome dispersal and environmental limitations based on revisiting an experiment with the aim to restore Pannonian sand grasslands on old fields, 16 years after its start. Treatments were carried out...

Preliminary assessment of cavity-nesting Hymenopterans in a low-intensity agricultural landscape in Transylvania

Károly Lajos, Imre Demeter, Róbert Mák, Adalbert Balog & Miklós Sárospataki
In this study our aim was to assess several traits of cavity-nesting Hymenopteran taxa in a low-intensity agricultural landscape in Transylvania. The study took place between May and August 2018 at eight study sites in the hilly-mountainous central part of Romania, where the majority of the landscape is used for extensive farming or forestry. During the processing of the trap-nest material, we recorded several traits regarding the nests of different cavity-nesting Hymenopteran taxa and the...

Post-restoration grassland management overrides the effects of restoration methods in propagule-rich landscapes

Csaba Tölgyesi, Csaba Vadász, Róbert Kun, András Csathó, Zoltán Bátori, Alida Hábenczyus, László Erdős & Péter Török
Grassland restoration is gaining momentum worldwide to tackle the loss of biodiversity and associated ecosystem services. Restoration methods and their effects on ecological community reassembly have been extensively studied across various grassland types, while the importance of post-restoration management has so far received less attention. Grassland management is an important surrogate for natural disturbances, which most ancient grasslands have co-evolved with. Thus, without the reintroduction of management-related disturbance, restoration targets are unlikely to be achieved...
