Cím:	Trade of commercial potting substrates: A largely overlooked means of the long-distance dispersal of plants / Judit Sonkoly, Attila Takács, Attila Molnár V., Péter Török

Megjegyzések:	Although long-distance dispersal (LDD) events are rare and stochastic, they are disproportionately important and drive several large-scale ecological processes; yet, we have a very limited understanding of their frequency, extent and con-sequences. Humanity intentionally spreads several species, which is associated with the accidental dispersal of other plant species. Although the global trade of potted plants and horticultural substrates may disperse large quantities of propagules, it has hardly been studied from an ecological point of view. We assessed the viable seed content of dif-ferent types of commercial potting substrates to answer the following questions: (i) In what richness and density do substrates contain viable seeds? (ii) Does the composition of substrates influence their viable seed content? and (iii) Are there common characteristics of the species dispersed this way? We detected 438 seedlings of 66 taxa and found that 1 l of potting substrate contains an average of 13.27 seeds of 6.24 species, so an average 20-liter bag of sub-strate contains 265 viable seeds. There was a high variability in the seed content of the substrates, as substrates con-taining manure contained a substantially higher number of species and seeds than substrates without manure. Thus, this pathway of LDD is an interplay between endozoochory by grazing livestock and accidental human-vectored dis-persal, implying that the diet preference of grazing animals influences the ability of a plant species to be dispersed this way. According to our results, potting substrates can disperse large quantities of seeds of a wide range of plant spe-cies over large distances. We conclude that this kind of human-vectored LDD may have complex effects on plant pop-ulations and communities; however, as this dispersal pathway is largely understudied and has hardly been considered as a type of LDD, its consequences are still unknown and further studies of the issue are of great importance.

Cím:	How to not trade water for carbon with tree planting in water-limited temperate biomes? / Csaba Tölgyesi, Alida Anna Hábenczyus, András Kelemen, Péter Török, Orsolya Valkó, Balázs Deák, László Erdős, Benedek Tóth, Nándor Csikós, Zoltán Bátori

Megjegyzések:	The most widespread nature-based solution for mitigating climate change is tree planting. When realized as forest restoration in historically forested biomes, it can efficiently contribute to the sequestration of atmospheric carbon and can also entail significant biodiversity and ecosystem service benefits. Conversely, tree planting in naturally open biomes can have adverse effects, of which water shortage due to increased evapotranspiration is among the most alarming ones. Here we assessed how soil texture affects the strength of the trade-off between tree cover and water balance in the forest-steppe biome, where the global pressure for afforestation is threatening with increasing tree cover above historical levels. Here we monitored vertical soil moisture dynamics in four stands in each of the most common forest types of lowland Hungary on well-drained, sandy (natural poplar groves, and Robinia and pine plantations) and on poorly drained, silty-clayey soils (natural oak stands and Robinia plantations), and neighboring grasslands. We found that forests on sand retain moisture in the topsoil (approx. 20 cm) throughout the year, but a thick dry layer develops below that during the vegetation period, significantly impeding groundwater recharge. Neighboring sandy grasslands showed an opposite pattern, with often dry topsoil but intact moisture reserves below, allowing deep percolation. In contrast, forests on silty-clayey soils did not desiccate lower soil layers compared neighboring grasslands, which in turn showed moisture patterns similar to sandy grasslands. We conclude that, in water-limited temperate biomes where landscape-wide water regime depends on deep percolation, soil texture should drive the spatial allocation of tree-based climate mitigation efforts. On sand, the establishment of new forests should be kept to a minimum and grassland restoration should be preferred. The trade-off between water and carbon is less pronounced on silty-clayey soils, making forest patches and wooded rangelands viable targets for both climate mitigation and ecosystem restoration.

Megjegyzések:	There are contrasting opinions on the use of prescribed burning management in European grasslands. On the onehand, prescribed burning can be effectively used for the management of open landscapes, controlling dominantspecies, reducing accumulated litter or decreasingwildfire risk. On the other hand burning can have a detrimentalimpact on grassland biodiversity by supporting competitor grasses and by threatening several rare and endangeredspecies, especially arthropods.We studied the effects of prescribed burning in alkaline grasslands of highconservation interest. Our aim was to test whether dormant-season prescribed burning can be an alternativeconservation measure in these grasslands. We selected six sites in East-Hungary: in three sites, a prescribedfire was applied in November 2011, while three sites remained unburnt. We studied the effects of burning onsoil characteristics, plant biomass and on the composition of vegetation and arthropod assemblages (isopods, spiders,ground beetles and rove beetles). Soil pH, organic matter, potassium and phosphorous did not change, butsoluble salt content increased significantly in the burnt sites. Prescribed burning had several positive effects fromthe nature conservation viewpoint. Shannon diversity and the number of flowering shoots were higher, and thecover of the dominant grass Festuca pseudovinawas lower in the burnt sites. Graminoid biomasswas lower,whiletotal, green and forb biomasswere higher in the burnt plots compared to the control. The key finding of our study was that prescribed burning did not decrease the abundance and diversity of arthropod taxa. Species-level analysesshowed that out of the most abundant invertebrate species, 10 were not affected, 1 was negatively and 1 waspositively affected by burning. Moreover, our results suggest that prescribed burning leaving unburnt patchescan be a viable management tool in open landscapes, because it supports plant diversity and does not threatenarthropods.
