In restored peatlands, recovery of carbon assimilation by peat-forming plants is a prerequisite for the recovery of ecosystem functioning. Restoration by rewetting may affect moss photosynthesis and respiration directly and/or through species successional turnover. To quantify the importance of the direct effects and the effects mediated by species change in boreal spruce swamp forests, we used...

[1] Wetland restoration is a commonly used approach to reduce nutrient loading to freshwater and coastal ecosystems, with many wetland restoration efforts occurring in former agricultural fields. Restored wetlands are expected to be effective at retaining or removing both nitrogen and phosphorus (P), yet restoring wetland hydrology to former agricultural fields can lead to the release of legacy...

Abstract The effect of rapid rewetting dry soil to a water content optimal for microbial activity on respiration and nutrient cycling has been extensively studied. However, with smaller rainfall events, may also rewet more slowly an interval between partial events. In this experiment, unamended or amended faba bean residue (C/N 9) was incubated at 50% water-holding capacity (WHC) 2 weeks, then ...

To better understand how water stress and availability affect the structure of microbial communities in soil, I measured the change in phospholipid fatty acids (PLFA) and the incorporation of C-labeled glucose into the PLFA following exposure to water stress. Overlaid on the laboratory water stress treatment, samples were collected from drought-prone and irrigated (11 years) tallgrass prairie s...

The intermittent drying characteristics of an Iranian popular paddy rice variety were experimentally investigated to determine the drying kinetics and obtain the effective moisture diffusivity. A lab-scale fluidized bed dryer was designed and constructed to enable obtaining the required results while controlling critical drying parameters. The effects of drying temperature and tempering per...

in this research the thin layer drying behavior of apricot (cv. ghavami and nasiry) at temperatures of drying air of 40, 50, 60 and 70 ºc and at drying air velocity of 2 ms-1 was studied. in order to select the best drying curve equation, 9 different thin layer drying models were fitted to the experimental data and were compared according to their coefficient of determination (r2), reduced chi-...
