Abstract Soils represent a major global source and sink of greenhouse gases (GHGs). Many studies GHG fluxes between soil, plant atmosphere rely on chamber measurements. Different techniques have been developed over the last decades, each characterised by different requirements limitations. In this manuscript, we focus non‐steady‐state technique which is widely used for manual measurements but also in automatic systems. Although measurement method appears very simple, experience gained years...
The estimations of greenhouse gas (GHG) field emissions from fertilization and soil carbon changes are challenges associated with calculating the footprint (CFP) agricultural products. At regional level, IPCC Guidelines for National Greenhouse Gas Inventories (2006a) Tier 1 approach, based on default emission factors, insufficiently accounts variability resulting pedo-climatic conditions or management practices. However, 2 3 approaches usually considered too complex to be practicable. In...
The rapid environmental changes associated with climate change increase the need for adaptation strategies in forest management based on profound knowledge about tree species, particularly context of assisted migration. For research purposes, selected native and non-native species were planted Brandenburg, Germany more than 120 years ago. Today, these sites provide an opportunity to gather insights their performance growth-response throughout past century. We analyzed height growth increment...
Black Cherry (Prunus serotina Ehrh.) is a broadleaved tree species native to Northern- and Central-America which was introduced in many other parts of the world, especially European countries. In places it has been classified as an invasive its management subject hotly debates. This review provides overview existing knowledge on ecology this non-native range, with special focus Europe. Based reviewed literature, fast-growing light-demanding forest gap specialist, tolerates most soil...
Abstract. Processes driving the production, transformation and transport of methane (CH4) in wetland ecosystems are highly complex. We present a simple calculation algorithm to separate open-water CH4 fluxes measured with automatic chambers into diffusion- ebullition-derived components. This helps reveal underlying dynamics, identify potential environmental drivers and, thus, calculate reliable emission estimates. The flux separation is based on identification ebullition-related sudden...
Deadwood (woody debris (WD), standing dead trees (snags), stumps, and buried deadwood) abundance was estimated in Labrador humid high-boreal black spruce (Picea mariana (Mill.) BSP) forests regrown following natural anthropogenic disturbances. Aboveground deadwood (DW) similar to values observed other boreal experiencing drier or warmer climates. Clear-cut harvest generated large amounts of WD, which had almost completely decomposed 34–36 years harvesting, with a fitted volume reduction rate...
Abstract Manual closed‐chamber measurements are commonly used to quantify annual net CO 2 ecosystem exchange (NEE) in a wide range of terrestrial ecosystems. However, differences both the acquisition and gap filling manual data large existing literature, complicating inter‐study comparisons meta analyses. The aim this study was compare common approaches for quantifying at three methodological levels. (1) first level included two different flux measurement methods: one via during mid‐day...
Abstract. The drainage and cultivation of fen peatlands create complex small-scale mosaics soils with extremely variable soil organic carbon (SOC) stocks groundwater levels (GWLs). To date, the significance such sites as sources or sinks for greenhouse gases CO2 CH4 is still unclear, especially if are used cropland. As individual control factors GWL fail to account this complexity, holistic approaches combining gas fluxes underlying processes required understand (C) exchange drained fens. It...
Abstract Today, a large share of mineral fertilizer is substituted by biogas digestates. Biogas digestates are known to promote N 2 O production, compared fertilizer. In particular, the initial phase following application crucial for gas release as and also . However, this period impact has been rarely investigated, especially not across various field sites. Thus, undisturbed soil cores from two types (biogas digestate vs fertilizer) at five sites with different site characteristics were...

Thus, serious challenges constitutes terms mechanistic process understanding, identification potential environmental drivers calculation reliable CH4 emission estimates. We present a simple algorithm to separate open-water fluxes measured with automatic chambers into diffusion- ebullition-derived components, which helps facilitating underlying dynamics drivers....
Selected quality aspects of natural regeneration in gaps were studied two sugar maple-yellow birch forest stands Quebec: a selection-cut stand (SC) and protected old-growth (OG). The quality-assessment systems by Sonderman (1979) Börner et al. (2003) applied to saplings poles maple (Acer saccharum Marsh.), yellow (Betula alleghaniensis Britton), American beech (Fagus grandifolia Ehrh.) between 2.5‐13.0 m height assess stem deviation, forks, the number live branches, branch diameters, overall...
