“…Exact values are presented in Filipiak (2016, see supplemental Table 3). To calculate the C:X ratios for exemplary food sources of these insects, which constitute the numerator in the TSR index, I applied data on variously decomposed dead wood of different species of angiosperms and gymnosperms based on data collected worldwide (Grier 1978;Lambert et al 1980;Foster and Lang 1982;Harmon et al 1986;Preston et al 1998Preston et al , 2009Palviainen et al 2010a, b;Filipiak and Weiner 2014;Johnson et al 2014;Köster et al 2015;Palviainen and Finér 2015;Pearson et al 2017). Considering all the above studies, the wood was aged 0-64 years after tree death.…”

Dead wood is rich in sugars and can serve as an energy source when digested, but it lacks other nutrients, preventing the growth, development, and maturation of saproxylophages (saproxylic organisms that consume dead wood at any stage of decomposition). Split into atoms, sugars only serve as a source of carbon, hydrogen, and oxygen, thereby providing insufficient nutrition for saproxylophages and for their digestive tract symbionts, despite the ability of certain symbionts to assimilate nitrogen directly from the air. Ecological stoichiometry framework was applied to understand how nutritional scarcity shapes saproxylophage-dead wood interactions. Dead wood is 1-3 orders of magnitude inadequate in biologically essential elements (N, P, K, Na, Mg, Zn, and Cu), compared to requirements of its consumers, preventing the production of necessary organic compounds, thus limiting saproxylophages' growth, development, and maintenance. However, the wood is nutritionally unstable. During decomposition, concentrations of the biologically essential elements increase promoting saproxylophage development. Three mechanisms contribute to the nutrient dynamics in dead wood: (1) C loss, which increases the concentration of other essential elements, (2) N fixation by prokaryotes, and (3) fungal transport of outside nutrients. Prokaryotic N fixation partially mitigates the limitations on saproxylophages by the scarcity of N, often the most limiting nutrient, but co-limitation by seven elements (N, P, K, Na, Mg, Zn, and Cu) may occur. Fungal transport can shape nutrient dynamics early in wood decay, rearranging extremely scarce nutritional composition of dead wood environment during its initial stage of decomposition and assisting saproxylophage growth and development. This transport considerably alters the relative and total amounts of non-C elements, mitigating also nutritional constraints experienced by saproxylophages inhabiting such nutritionally enriched wood during

“…This tendency appeared on the fourth year after harvesting, and is still there, but the differences are becoming less pronounced. The length of the period when differences were observed corresponds to the time of logging residue decomposition (Pearson et al, 2017;Vávřová et al, 2009) indicating the importance of nutrient supply from this source in SOH treatment plot in oligotrophic conditions.…”

“…There are several mechanisms that influence the possible effects. Slash left on felling site provide nutrients for the regenerated stand for several years while decomposing (Hosseini Bai et al, 2014;Pearson et al, 2017;Vávřová et al, 2009); in addition, slash may act as a nutrient sink reducing leaching of nutrients from the site (Barber & Van Lear, 1984). Furthermore, slash supresses the expansion of plants by lowering the competition by ground vegetation to tree saplings (Fahey et al, 1991).…”

Forest management pressures on ecosystems are expected to rise due to increased use of renewable resources and environmental, economic and political reasons. Extraction of nutrient rich logging residues from felling sites has become a common practice, therefore risks of negative impact on the nutrient cycling as well as site future productivity must be assessed. To evaluate effect of whole-tree harvesting (WTH) and whole-tree harvesting combined with stump biomass extraction (WTH+SB) on productivity of next rotation young stands measurements were carried out in eight sites for four to six years in typical forest site types in Latvia (Oxalidosa turf. mel.eutrophic peat soil site; Hylocomiosa, Oxalidosamesotrophic mineral soil sites, Mytrillosaoligotrophic mineral soil site). Harvesting in the sites was carried out in 2012-2013 and regeneration was carried out after one to two years with Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies L. (Karst.)) and black alder (Alnus glutinosa L. (Gaertn.)). Comparing conventional harvesting or so-called stem only harvesting (SOH) to WTH no statistically significant differences were observed regarding tree height, but in eutrophic Norway spruce site WTH plot smaller stem diameters were observed. Comparing WTH to WTH+SB statistically significantly higher Norway spruce and black alder heights in mono-stands were observed in WTH plots, while no significant differences were detected in Norway spruce and black alder mixed stand. No explicit differences were found regarding height/diameter ratio between WTH and WTH+SB treatments.
