We found in a pilot research that restoring former floodplains can transform landscapes from greenhouse gas emitters into sinks. Shifting from arable land to sustainable land use in floodplain areas supports both climate and biodiversity goals.

The relative allocation within a plant species of asexual vs. sexual reproduction is predicted to vary according to changing environmental conditions. In bryophytes, sex expression is predicted to be reduced in unfavourable environments because sporophyte maturation is resource‒limited. The allocation between reproductive strategies in the bryophyt...

Human well-being needs healthy ecosystems, providing multiple ecosystem services. Therefore, the assessment of ecosystems on large scales is a priority action. In Hungary, this work (MAES-HU) took place between 2016 and 2022. Twelve ecosystem services (ES) were mapped and assessed along with several ecosystem condition (EC) indicators. Their integr...

Abstract Aims: The relative importance of species within an ecosystem shows spatio-temporal variability related to both the terrain features and numerous rapidly changing factors. Accordingly, functional and species patterns may show some level of persistence, or, due to various disturbances, fluctuations. Communities with high species richness wer...

Mapping and assessing ecosystem services (ES) projects at the national level have been implemented recently in the European Union in order to comply with the targets set out in the EU’s Biodiversity Strategy for 2020 and later in the Strategy for 2030. In Hungary this work has just been accomplished in a large-scale six-year project. The Hungarian...

Grasslands could play an important role in supporting livestock, in carbon sequestration and in biodiversity conservation. Different grassland managements may change the vegetation composition of grasslands, which could alter these ecosystem services. We studied the effects of grazing vs. mowing on the vegetation composition (2012–2016) and on the...

Soil respiration of grasslands is spatio-temporally variable reflecting the changing biological activities of the soil. In our study we analysed how the long-term soil respiration activities of dry grasslands would perform in terms of resistance and resilience. We also investigated how terrain features are responsible for response stability. We con...

Az Európai Unió 2020-ig megvalósítandó Biodiverzitás Stratégiájának egyik fő célkitűzése az ökoszisztéma-szolgáltatások (ÖSz-ek) minél teljesebb megőrzése és helyreállítása. Ennek érdekében a tagországok számára előírják, hogy térképezzék és értékeljék a területükön található ökoszisztémák állapotát (ÖÁ), valamint az általuk nyújtott ÖSz-ek helyzet...

Understanding management-induced C sequestration potential in soils under agriculture, forestry, and other land use systems and their quantification to offset increasing greenhouse gases are of global concern. This chapter reviews management-induced changes in C storage in soils of grazing grassland systems, their impacts on ecosystem functions, an...

The potential of grasslands as a carbon (C) sink in Europe is large despite the number of uncertainties related to the effect of grazing systems on C sequestration. The EIP-AGRI Focus Group (FG) ‘Grazing for Carbon’, a temporary group of 20 selected European experts from research and practice, shared knowledge and experience from different discipli...

ABSTRACT. In this study we provide the first record of bryophyte community diversities in contrasting habitats of the Torngat Mountains National Park (Labrador, Canada), a coastal mountain subarctic ITEX (International Tundra Experiment) study site. The point-intercept method was used to describe and track changes in the bryophyte community diversi...

To evaluate the damaging effect of tropospheric ozone on vegetation, it is important to evaluate the stomatal uptake of ozone. Although the stomatal flux is a dominant pathway of ozone deposition onto vegetated surfaces, non-stomatal uptake mechanisms such as soil and cuticular deposition also play a vital role, especially when the leaf area index...

Spatial patterns of ecosystem processes constitute significant sources of uncertainty in greenhouse gas flux estimations partly because the patterns are temporally dynamic. The aim of this study was to describe temporal variability in the spatial patterns of grassland CO2 and N2O flux under varying environmental conditions and to assess effects of...

Livestock is both threatened by and contributing to climate change. The contribution of livestock to climate change and greenhouse gas (GHG) emission greatly vary under different management regimes. A number of mitigation options comprise livestock management, although there are a lot of uncertainties as to which management regime to use for a give...

In this study eight temperate grassland sites were monitored for soil CO2 efflux (Rs) and the spatial covariate soil water content (SWC) and soil temperature (Ts) at fine scale in over 77 measurement campaigns. The goals of this multisite study were to explore the correlations between environmental gradients and spatial patterns of Rs, SWC and Ts,...

Different management practices may change the rate of soil respiration, thus affecting the carbon balance of grasslands. Therefore, we investigated the effect of grazing and mowing on soil respiration along with its driving variables (soil water content, soil temperature, above and below ground biomass, vegetation indices and soil carbon) in adjace...

Az utóbbi évtizedben zajló kutatások kimutatták, hogy a talajok CO 2 -kibocsátása jelentős napi és szezonális változékonyságot mutat. A manuális mérőrendszerekkel azonban ez nehezen követhető nyomon. Éppen ezért megjelent az igény a nagyobb időbeli felbontású automata mérőrendszerekre, több gyártó készítette el saját fejlesztésű műszerét. Ezeknek a...

High variability of soil respiration measured at fine spatial scale increases the uncertainty when trying to determine the representative average soil respiration (Rs) flux. A possible way to decrease the uncertainty, while also optimising measurement effort, could be the calculation of required number of Rs measurements (Nopt) together with the op...

Grasslands play an important role in carbon sequestration. Different management regimes may change the species composition of plants in grasslands, thus may affect the carbon sequestration potential. Therefore, we investigated if short-term changes in species composition occurred in response to shift in grazing to mowing in a semi-arid grassland in...

The relative allocation within a plant species of asexual vs. sexual reproduction is predicted to vary according to changing environmental conditions. In this study, the allocation between reproductive strategies in the bryophyte, Polytrichum juniperinum was examined in the low-arctic Torngat Mountains, Labrador, Canada in 2008/2009 along both an e...

Information on how climate change will affect terrestrial ecosystems of northern Labrador is limited. A systematic baseline data on the terrestrial ecosystems including mosses are needed to asses any potential impacts. Mosses contribute 30% to the vegetation cover of the tundra and they play an important role in the biogeochemistry processes of the...

A világ egyik legnagyobb tudományos együttműködése kezdődött el 2007-ben, amikor meghirdették a Nemzetközi Poláris Évet (www.ipy.org)1. A program csupán a nevében jelöl egy évet, mivel valójában három évet (2007-2009) és a további időszakot is felöleli. Hiszen a Nemzetközi Poláris Év arra vállalkozott, hogy meteorológiai, geológiai, biológiai, gazd...

The effects of drought and heat wave appeared in growing season of 2003 on some physiological traits of Quercus petraea were studied at the Sikfôkút research site. There were comparative measurements in the subsequent humid growing season of 2004. Drought reduced significantly the leaf mass increment of Quercus petraea in the dry year (2003) which...

Responses of some physiological traits of Quercus petraea to drought was studied at the Sikfokut research site in the dry and humid growing seasons of 2003 and 2004. Drought reduced significantly the leaf mass increment of Quercus petraea in the dry year (2003). SLM was lower in 2003 than in 2004. Chlorophyll content showed inter-annual and within-...

In this study the variability of leaf growth traits was investigated within the canopy of the two dominant tree species of Quercetum petraeae-cerris forest community, covering 30 % of the present forested area in Hungary. The investigation were performed in the "Sikfokut Project" LTER site (Jakucs 1985). We compared the present leaf growth traits o...
