In particular when so-called \u2018priming effects\u2019, the counterintuitive loss of soil carbon following input of organic carbon substrates, are taken into consideration. Here we investigate the dynamics of priming effects and ask whether the source of primed carbon is microbial biomass or soil organic matter and whether specific microbial groups, as identified by phospholipid fatty acid (PLFA) biomarkers, may be important in causing them. We measured \u03b413C within soil CO2 efflux and PLFA biomarkers following C3 soil priming effects caused by additions of C4 sugar-cane sucrose and maize (Zea mays L.) leaf-litter chopped and ground. All additions caused an initial pulse of priming effect CO2 and a later pulse of substrate-derived CO2, showing that priming effects can be induced rapidly following changes in substrate supply. Priming effects persisted over 32 days and led to a loss of soil carbon, with an increase in soil carbon decomposition of 169% following sucrose addition, 44% following chopped maize and 67% following ground maize additions. An increased concentration of soil-derived carbon within specific PLFA biomarkers provided evidence that a source of the primed carbon was soil organic matter. Certain Gram negative bacteria, identified by PLFA biomarkers (16:1\u03c95, 16:1\u03c97), showed increased uptake of soil carbon for both sucrose and maize treatments and may be directly linked to priming effects. Our study provides evidence that substrate carbon inputs to soil induce rapid changes in specific microbial groups, which in turn increase soil carbon metabolism.", "keywords": ["priming effect", "2.

Three treatments were setup in 0.125 ha plots and replicated in three blocks at the harvesting of a Congolese Eucalyptus stand, resulting in an aboveground organic residue mass ranging from 0 to 6.3 kg m \ufffd 2 . The mineralization of SOM was deduced in each treatment by partitioning sources of soil CO2 effluxes using decomposition experiments and by upscaling specific root respiration. Soil CO2 effluxes were greatly affected by seasons and organic residue manipulation, although there were no significant changes in topsoil water content and topsoil temperature over most of the study period. Aboveground organic residue was the first contributor to soil CO2 efflux in the two treatments with a litter layer. Organic residue management did not significantly influence the mineralization of SOM in our study, probably due to the low quality of Eucalyptus litter, or to the hypothetical lack of dissolved organic carbon transfers from litter to soil.

The study was carried out from November 2005 to April 2006. A completely randomized sampling design was established in six sites (B1, B2, AF1, AF2, S1 and S2). Soil properties and chemical characteristics (texture, pH, organic carbon (Corg), nutrients, and available Zn and Mn), earthworm communities and the decomposition of Bravaisia integerrima and Musa acuminata litter were analyzed over a period of 8 weeks.  All soils were loamy clays with a medium to high content of nutrients. Three principal clusters were generated with the soil chemical properties: a first cluster for forest soils with high Corg and Ntot and low available Zn content, a second cluster for AF1 and a third cluster for B1, B2 and A2.  The decomposition of B. integerrima litter was significantly faster (half-life time: 1.8 (AF2)\u20133.1 (B1) weeks) than that of M. acuminata (4.1 (AF2)\u20135.8 (S2) weeks). However, the decomposition rates did not differ significantly among the different sites.  The greatest earthworm diversities were observed in AF2 and B1. Native species were dominant in the forest soils, whereas exotic species dominated in AF and in the banana plantations. The abundance and biomass of certain earthworm species were correlated to physical and chemical soil parameters. However, litter decomposition rates were not correlated with any of the soil physical\u2013chemical parameters.

In forests, roughly half of the soil respiration is autotrophic (mainly root respiration) while the remainder is heterotrophic, originating from decomposition of soil organic matter. Decomposition is an important process for cycling of nutrients in forest ecosystems. Hence, tree species induced changes may have a great impact on atmospheric CO2 concentrations. Since studies on the combined effects of beech\u2013spruce mixtures are very rare, we firstly measured CO2 emission rates in three adjacent stands of pure spruce (Picea abies), mixed spruce\u2013beech and pure beech (Fagus sylvatica) on three base-rich sites (Flysch) and three base-poor sites (Molasse; yielding a total of 18 stands) during two summer periods using the closed chamber method. CO2 emissions were higher on the well-aerated sandy soils on Molasse than on the clayey soils on Flysch, characterized by frequent water logging. Mean CO2 effluxes increased from spruce (41) over the mixed (55) to the beech (59) stands on Molasse, while tree species effects were lower on Flysch (30\u201335, mixed > beech = spruce; all data in mg CO2\u2013C m\u22122 h\u22121). Secondly, we studied decomposition after fourfold litter manipulations at the 6 mixed species stands: the Oi \u2013 and Oe horizons were removed and replaced by additions of beech \u2013, spruce \u2013 and mixed litter of the adjacent pure stands of known chemical quality and one zero addition (blank) in open rings (20 cm inner diameter), which were covered with meshes to exclude fresh litter fall. Mass loss within two years amounted to 61\u201368% on Flysch and 36\u201344% on Molasse, indicating non-additive mixed species effects (mixed litter showed highest mass loss). However, base cation release showed a linear response, increasing from the spruce \u2013 over the mixed \u2013 to the beech litter. The differences in N release (immobilization) resulted in a characteristic converging trend in C/N ratios for all litter compositions on both bedrocks during decomposition. In the summers 2006 and 2007 we measured CO2 efflux from these manipulated areas (a closed chamber fits exactly over such a ring) as field indicator of the microbial activity. Net fluxes (subtracting the so-called blank values) are considered an indicator of litter induced changes only and increased on both bedrocks from the spruce \u2013 over the mixed \u2013 to the beech litter. According to these measurements, decomposing litter contributed between 22\u201332% (Flysch) and 11\u201328% (Molasse) to total soil respiration, strengthening its role within the global carbon cycle.", "keywords": ["DYNAMICS", "0106 biological sciences", "FLUXES", "Fagus sylvatica", "NUTRIENT RELEASE", "BROADLEAF", "Nutrient cycling", "01 natural sciences", "Mixed species effects", "507015 Regionalforschung", "FORESTS", "FAGUS-SYLVATICA", "CO(2) efflux", "SDG 15 \u2013 Leben an Land", "SDG 15 - Life on Land", "Picea abies", "Litter decomposition", "NORWAY SPRUCE", "04 agricultural and veterinary sciences", "15.

Soils from three cultivated areas (two types of rainfed upland and one irrigated lowland) and two forests (subtropical managed and temperate unmanaged) in a midhill watershed of Nepal were studied to assess the effect of land use change on SOM quality. Bulk SOM was analyzed using solid\uffe2\uff80\uff90state13C nuclear magnetic resonance (NMR) and fractionated by acid hydrolysis into pools with different chemical composition and, thus, different tendencies to decomposition. The NMR analysis showed a clear prevalence of O\uffe2\uff80\uff90alkyl C over alkyl C and aromatic C, with major differences between both soils and two depth intervals of the same soil (0\uffe2\uff80\uff9320 and 20\uffe2\uff80\uff9340 cm). Acid hydrolysis revealed that the labile C pool is larger in the 0\uffe2\uff80\uff90 to 20\uffe2\uff80\uff90 than the 20\uffe2\uff80\uff90 to 40\uffe2\uff80\uff90cm soil depth of each land use. Labile C was larger in the temperate unmanaged forest and the irrigated cultivated land than in the other soils at both soil depths. Of the cultivated rainfed soils, the recently reclaimed soil contained less labile C than the historically cultivated soil, while the labile C in the irrigated soil exceeded that in both rainfed soils. The results suggest that changes in land use from forest to cultivation and the irrigation of the cultivated land may significantly affect not only the quantity but also the quality of the SOM and, more importantly, its chemical recalcitrance to degradation. As a consequence, any future decisions regarding land management in the fragile mountain areas of Nepal should be carefully considered with respect to the nature of the SOM.</p>", "keywords": ["2.

We compared three levels of organic matter removal (stem-only, whole-tree harvest, and scalped mineral soil) and two levels of compaction (no compaction and heavy compaction) in a factorial design replicated as blocks on three sites. Whole-tree harvesting significantly increased litter decomposition rates compared to stem-only (by 36%) and scalped (by 41%) treatments. Soil compaction had inconsistent effects on decomposition rates (k) for forest floor and scalped treatments and, overall, did not significantly affect litter decomposition rates. Litter on scalped plots had higher rates of nutrient translocation than litter on forest floors. We found the treatments altered soil heat sums, so changes in temperatures at the soil surface might be partly responsible for the changes in decomposition rates. We could not detect differences in soil mesofauna populations collected from the litter bags, so treatment effects on fauna probably had less influence than microclimate on decomposition rates. The effects of these early changes in litter decomposition on biological productivity will be part of the ongoing long-term soil productivity study.

The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the Outline of Fungi and fungus-like taxa, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the Outline of Fungi website (https://www.outlineoffungi.org/), and these will be finally published in the biannual edition of the Outline of Fungi and fungus-like taxa. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, \u2018to promote a more stable taxonomy in Fusarium given the divergences over its generic delimitation\u2019, or \u2018are there too many genera in the Boletales?\u2019 and even more importantly, \u2018what should be done with the tremendously diverse \u2018dark fungal taxa?\u2019 There are undeniable differences in mycologists\u2019 perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others\u2019 work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa.
