“…While many investigations have addressed the nature and dynamics of DOM in terrestrial ecosystems (e.g. Currie et al, 1996), only a few have investigated the dynamics (Carlisle et al, 1966;Sollins et al, 1980;le Mellec et al, 2009le Mellec et al, , 2010 and none the character of water-bound total OM (TOM) including the particulate organic matter fraction (POM; 0.45 µm < POM < 500 µm). Since water-bound element and nutrient concentrations are conventionally measured after filtration (frequently to < 0.45 µm pore size), the exclusion of the POM frac-tion potentially results in misleading inferences and budgeting gaps in studies of nutrient and energy fluxes in ecosystems (Michalzik and Stadler, 2005;Stadler et al, 2006).…”

“…We are aware of only a handful of studies over the last 35 years which address POM or size equivalents in temperate broadleaved and coniferous ecosystems (e.g. Carlisle et al, 1966;Sollins et al, 1980;Likens et al, 1983;Lamersdorf and Blank, 1995;Levia et al, 2013). The majority of these studies highlighted the importance of organic matter (OM) > 0.45 µm to the overall budgets of C, N and other nutrients.…”

Abstract. We present the first investigation of the composition of dissolved organic matter (DOM) compared to total organic matter (TOM, consisting of DOM, < 0.45 µm and particulate organic matter 0.45 µm < POM < 500 µm) in throughfall, stemflow and forest floor leachate of common beech (Fagus sylvatica L.) and Norway spruce (Picea abies (L.) H. Karst.) forests using solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy. We hypothesized that the composition and properties of organic matter (OM) in forest ecosystem water samples differ between DOM and TOM and between the two tree species.The 13 C NMR results, derived from 21 samples, point to pronounced differences in the composition of DOM and TOM in throughfall solution at the beech sites, with TOM exhibiting higher relative intensities for the alkyl C region, which represents aliphatic C from less decomposed organic material compared to DOM. Furthermore, TOM shows lower intensities for lignin-derived and aromatic C of the aryl C region resulting in lower aromaticity indices and a diminished degree of humification. Across the ecosystem compartments, differences in the structural composition of DOM and TOM under beech lessened in the following order: throughfall > stemflow ≈ forest floor leachate.In contrast to the broadleaved sites, differences between DOM and TOM in throughfall solution under spruce were less pronounced and spectra were, overall, dominated by the alkyl C region, representing aliphatic C. Explanations of the reported results might be substantiated in differences in tree species-specific structural effects, leaching characteristics or differences in the microbial community of the tree species' phyllosphere and cortisphere. However, the fact that throughfall DOM under beech showed the highest intensities of recalcitrant aromatic and phenolic C among all samples analysed likely points to a high allelopathic potential of beech trees negatively affecting other organisms and hence ecosystem processes and functions.

“…This might indicate that nitrogen, particularly N0 3 -N, is absorbed by the needles, or taken up by epiphytes living on the boles of trees. Particularly in the case of sessile oak (Quercus petraea) it has been established that the amounts of inorganic nitrogen both in stemflow and in throughfall are smaller altogether than in precipitation (CARLISLE et al 1966(CARLISLE et al , 1967(CARLISLE et al a, 1967. This indicates that the trees might take up inorganic nitrogen directly through their leaves.…”

“…EATON et al (1973) use the term net removal to describe the nutrients which are leached from the canopy plus those washed from the surface of leaves, i.e., the net removal = nutrients leached + nutrients washednutrients in precipitation. On the other hand, it has been indicated that nutrients can be absorbed into the leaves from intercepted water or taken up by epiphytes on the surface of leaves and branches (INGHAM 1950;TUKEY et al 1958;CARLISLE et al 1966CARLISLE et al , 1967CARLISLE et al a, 1967.

A novel methodology was used to evaluate the contribution of Saharan dust to the atmospheric deposition of particulate material (PM), total phosphorus (TP), and total nitrogen (TN) in the southeastern Iberian Peninsula. Dry and wet aerosol depositions were measured weekly during two 1 year periods at one site and simultaneously during spring-summer of the same years at two other sites (intersite distance of 40 km). Statistical relationships among depositions at the different sites permitted differentiation of Saharan dust inputs from locally derived dust. PM and TP depositions were synchronous among the three study sites; the synchrony was elevated during periods of Saharan intrusions (evaluated by air mass retrotrajectories analyses), but no temporal correlation was observed during periods without Saharan intrusions. According to analysis of variance results, PM and TP depositions were both significantly affected by Saharan intrusions. During weeks with Saharan intrusions, PM deposition increased around 85% above background levels, with no differences among the three sites, while TP deposition increased by 1.1 μmol TP m À2 d À1 , i.e., 29% to 81% above background levels depending on the site. There were no correlations or differences in TN deposition among sites or as a function of Saharan intrusion periods. The annual contribution of PM and TP from Saharan dust was 75 kg ha À1 and 0.07 kg P ha À1 , respectively, which can be considered a genuine input for the ecosystems in this area. This novel approach is likely to be valid in any area in the world under atmospheric deposition of long-range transported material.
