“…It is well known that soil disturbance can cause local and temporal changes in soil properties such as aeration, pH, nutrient availability and in microbial community composition and activity (Allison and Martiny 2008;Dorland et al 2003;Wagner et al 2015;Wardle et al 2004), which all are known to affect litter decomposition (e.g., Hattenschwiler et al 2005;Veen et al 2015). In addition to previous studies however, our results now show that such disturbance effects can be modulated by litter type and flooding history.…”

Background and aims Since long-term experiments are scarce, we have poor understanding of how changed flooding regimes affect processes such as litter decomposition. Methods We simulated short-and long-term changed flooding regimes by transplanting turfs between low (frequently flooded) and high (in-frequently flooded) elevations on the river bank in 2000 (old turfs) and 2014 (young turfs). We tested how incubation elevation, turf origin and turf age affected decomposition of standard litter (tea) and four types of local litter. Results For tea, we found that the initial decomposition rate (k) and stabilization (S) of labile material during the second decomposition phase were highest at high incubation elevation. We found intermediate values for k and S in young transplanted turfs, but turf origin was not important in old turfs. Local litter mass loss was generally highest at high incubation elevations, and effects of turf origin and turf age were litter-specific. Conclusion We conclude that incubation elevation, i.e., the current flooding regime, was the most important factor driving decomposition. Soil origin (flooding history) affected decomposition of tea only in young turfs. Therefore, we expect that changes in flooding regimes predominantly affect decomposition directly, while indirect legacy effects are weaker and litter-or site-specific.

“…Samples were placed in plastic bags and taken back to the laboratory. Root samples were washed out of the soil as gently as possible through a 0.5 mm sieve and then dead roots were removed according to the method provided by Hefting et al (2005). Before measurements, all live roots were sealed in self-styled bags and placed in a cold chamber at 5°C (Burylo et al 2011).…”

“…The length of each step should be selected based on the typical time scale at 20 which hydrological processes happen in the simulated system. For example, the typical time scale for flow in 21 sandy-loamy soils is 1 d (Hefting et al, 2005;Kirschbaum, 1999). This value was used in the simulations 22 reported here, while for a coarser material (e.g., sandy gravel) a smaller time step would be required, as 23 coarse materials drain faster.…”

1The quality of riparian soils and their ability to buffer contaminant releases to aquifers and streams are 2 connected intimately to moisture content and nutrient dynamics, in particular of carbon (C) and nitrogen (N). 3A multi-compartment model -named the Riparian Soil Model (RSM) -was developed to help investigate 4 the influence and importance of environmental parameters, climatic factors and management practices on 5 soil ecosystem functioning in riparian areas. The model improves existing tools, in particular regarding its 6 capability to simulate a wide range of temporal scales, from days to centuries, along with its ability to predict 7 the concentration and vertical distribution of dissolved organic matter (DOM). It was found that DOM 8 concentration controls the amount of soil organic matter (SOM) stored in the soil as well as the respiration 9 rate. The moisture content was computed using a detailed water budget approach, assuming that within each 10 time step all the water above field capacity drains to the layer underneath, until it becomes fully saturated. A 11 mass balance approach was also used for nutrient transport, whereas the biogeochemical reaction network 12 was developed as an extension of an existing C and N turnover model. Temperature changes across the soil 13 profile were simulated analytically, assuming periodic temperature changes in the topsoil. Sustainable management of riparian soils is of primary importance to preserve natural ecosystem 3 functioning. Riparian zones are sources of ecosystem functions and services including biodiversity hotspots, 4 water quality enhancement, and recreation sites (Brinson et al., 1981;Naiman and Decamps, 1997). 5Throughout the world, the ecological condition of natural riparian systems has declined due to a number of 6 factors, including streamflow regulation, floodplain development, channelization, and the spread of non-7 native species (Naiman and Decamps, 1997;Naiman et al., 2005). Consequently, restoration of riparian areas 8 has become a global management priority (Hughes et al., 2005;Hughes and Rood, 2003; Webb and Erskine, 9 2003). 10 Soil ecosystem functioning is connected intimately to soil organic matter (SOM) turnover, a set of complex 11 and intertwined biological processes that recycle biotic residues (such as plant litter, dead organisms, etc.) to 12 inorganic molecules. Environmental and climatic factors affect decomposition rates, the biological activity of 13 the soil and ultimately SOM cycling (Laio et al., 2001;Porporato et al., 2003). Soil moisture has a direct 14 influence on the processes mediated by the soil biota (pedofauna, bacteria, fungi, etc.) because optimal 15 decomposition rates are achieved only in a narrow saturation range (Bell et al., 2008; Ju et al., 2006; 16 Porporato et al., 2003;Van Gestel et al., 1992). Owing to the strong dependence of ecological processes on 17 soil moisture, linear and non-linear interactions and feedbacks exist between hydrological processes and soil 18 ecosystem functionin...
