We investigated the effect of dominant deciduous tree species of the Central European forest vegetation, European beech (Fagus sylvatica L.) and European ash (Fraxinus excelsior L.), on soil biota and carbon dynamics differentiating between root- and leaf litter-mediated effects. The influence of beech and ash seedlings on carbon and nitrogen flow was investigated using leaf litter enriched in 13C and 15N in double split-root rhizotrons planted with beech and ash seedlings as well as a mixture of both tree species and a control without plants. Stable isotope and compound-specific fatty acid analysis (13C-PLFA) were used to follow the incorporation of stable isotopes into microorganisms, soil animals and plants. Further, the bacterial community composition was analyzed using pyrosequencing of 16S rRNA gene amplicons. Although beech root biomass was significantly lower than that of ash only beech significantly decreased soil carbon and nitrogen concentrations after 475 days of incubation. In addition, beech significantly decreased microbial carbon use efficiency as indicated by higher specific respiration. Low soil pH probably increased specific respiration of bacteria suggesting that rhizodeposits of beech roots induced increased microbial respiration and therefore carbon loss from soil. Compared to beech δ13C and δ15N signatures of gamasid mites in ash rhizotrons were significantly higher indicating higher amounts of litter-derived carbon and nitrogen to reach higher trophic levels. Similar δ13C signatures of bacteria and fine roots indicate that mainly bacteria incorporated root-derived carbon in beech rhizotrons.

To what extent changes in the species composition of temperate forests and increases in the frequency and duration of summer droughts in the course of global climate change will alter GHG emissions remains unclear. We analyzed the effect of tree species identity and mycorrhizal association type vs. soil drought on GHG fluxes by conducting a greenhouse experiment with four important deciduous tree species which form either ectomycorrhizal or arbuscular mycorrhizal associations. We combined soil gas flux measurements with analyses of leaf gas fluxes, potential fine root respiration, fine root growth and turnover, and N turnover in soil microsites. Our experiment tests the hypotheses that (1) GHG emissions differ between tree species and mycorrhizal association type mainly due to differences in root activity and root-induced processes, and (2) soil drought decreases the amount of GHG exchange from different tree species to a different extent. We found a two times higher global warming potential (GWP) from soil gas exchange in European ash than in the other three tree species (1.9 vs. 0.8–1.0 g CO2-eq kg−1 h−1) mainly due to much higher root mass-specific CO2 emission rates (495 vs. 210–236 mg C kg−1 h−1). Apart from the influence of species differences in fine root productivity, we show a stronger increase in CO2 emission rates per portion of white roots in ash which may indicate a higher metabolic activity of unsuberized fine roots in this tree species. Ectomycorrhizal tree species differed from arbuscular mycorrhizal tree species by a two times greater increase in CO2 emissions per fine root production. The N2O emissions per root mass were up to five times higher in beech than in the other species, caused either by higher nitrate production in the rhizosphere or by lower nitrate consumption. Soil porosity drove the amount of methane uptake, while biotic influences were subordinate. Soil drought generally exerted an important control on GHG fluxes: low water-filled pore space decreased the GWP from soil emissions by only 9% in sycamore, but by 40% (European beech) to 68% (European ash) in the other tree species and largely diminished any tree species differences.

Wetlands are sources for atmospheric methane and forest soils sinks. However, this greenhouse gas is also emitted by wet forest soils, which is commonly disregarded due to lacking information on their spatial distribution. Here, we estimated the potential bias made for the European methane budget of terrestrial ecosystems when neglecting wet forest ecosystems but including rice paddies and latest estimates for lakes. We appointed distinct annual methane rates for individual land use types based on a literature survey and weighted them according to their European area. This was performed separately for four major ecozones (cold, temperate, continental and Mediterranean). Three approaches were applied: (1) the mean values for forests and wetlands were calculated in three different scenarios, (2) assuming that boreal needle-leaved evergreen forest with a low tree cover (<40%) is predominately forested wetland (3) assuming different shares of wet forest ecosystems in individual forest areas. For the net balance 2.8 Tg CH4-C a(-1) were calculated which includes emissions from rice paddies (0.2 Tg CH4-C a(-1)) and from lakes (2.5 Tg CH4-C a(-1)). The different approaches for the net balances that included wet forest ecosystems mainly ranged between 4.6 and 6.7 Tg CH4-C a(-1). The results suggest that wet forest ecosystems are approximately as important as wetlands for the European methane balance.

This design excluded putative effects of leaf litter mineralisation on trace gas fluxes. Gas fluxes were measured biweekly using the closed chamber technique; the CO2 derived from root respiration was estimated, and the concentration of organic acids in the rhizosphere solution was analysed. Rhizotrons planted with ash took up significantly more CH4 and emitted less N2O than control rhizotrons without plants. CH4 and N2O fluxes from beech rhizotrons did not differ from the root-free control but were significantly smaller (CH4) or higher (N2O) than the fluxes from the ash treatment. While root respiration of ash was higher than of beech, root-induced soil respiration was higher in the rhizosphere of beech roots.

The aim of this study was to address the influences of tree species, tree species diversity and leaf litter on soil bacterial diversity and community composition. Therefore, mesocosm experiments using beech, ash, lime, maple and hornbeam were established in 2006, and sampled in October 2008 and June 2009. Mesocosms were planted with one, three or five different tree species and treated with or without litter overlay. Cluster analysis of DGGE-derived patterns revealed a clustering of 2008 sampled litter treatments in two separated clusters. The corresponding treatments sampled in 2009 showed separation in one cluster. PCA analysis based on the relative abundance of active proteobacterial classes and other phyla in beech and ash single-tree species mesocosm indicated an effect of sampling time and leaf litter on active bacterial community composition. The abundance of next-generation sequencing-derived sequences assigned to the Betaproteobacteria was higher in the litter treatments, indicating a higher activity, under these conditions. The Deltaproteobacteria, Nitrospira and Gemmatimonadetes showed an opposite trend and were more active in the mesocosms without litter. The abundance of alphaproteobacterial sequences was higher in mesocosms sampled in 2009 (P = 0.014), whereas the Acidobacteria were more active in 2008 (P=0.014).
