“…The extracellular walls of pollen are difficult to destroy chemically (Brooks et al, 1970), but they can be destroyed through mechanical disruption (crushing by chewing) or osmotic shock, which does not require special adaptations, to make pollen digestible (but see Franchi et al, 1997;Greenfield, 1999;Roulston and Cane, 2000;Johnson and Nicolson, 2001). Bacteria and fungi, however, are able to chemically destroy pollen walls (Brooks et al, 1970;Bradley, 2015;Shumilovskikh et al, 2015) and increase the productivity of the ecosystem through the introduction of pollen-derived nutrients to the food web (Masclaux et al, 2011(Masclaux et al, , 2013Rösel et al, 2012). Pollen rapidly decomposes in both terrestrial and aquatic ecosystems, liberating large amounts of nutritionally rich matter soon after deposition (Greenfield, 1999;Cho et al, 2003;Webster et al, 2008;Rösel et al, 2012).…”

“…Generally, the amount of pollen deposited annually by various plants (grasses, trees, and herbs) in different ecosystems varies from several to hundreds of kg/ha, but the majority of studies are only concerned with pine pollen (Richerson et al, 1970;Stark, 1972;Doskey and Ugoagwu, 1989;Greenfield, 1996Greenfield, , 1999Proctor et al, 1996;Lee et al, 1996a,b;Hicks, 1999;Perez-Moreno and Read, 2001;Cho et al, 2003;Lee and Booth, 2003;Graham et al, 2006;Shumilovskikh et al, 2015). Maggs (1985) showed that pollen constitutes 3.5% of the total mass of the yearly slash pine biomass fall (litterfall plus pollen rain) but accounts for up to 30% of the total amount of deposited N, P, and K, so one could compare the general patterns of mass and nutrient inputs from pollen and litter.…”

“…Indeed, it was suggested that, in detrital food webs, litter-decomposing fungi are colimited by the scarcity of N, P, and S in litter, which they mitigate by foraging on pollen and which allows them to complete litter decomposition (Stark, 1972;Staaf and Berg, 1982;Hutchison and Barron, 1997). Forests may produce pollen in masses reaching 100 to 1000 kg/ha (Greenfield, 1996), and the bulk of this mass is deposited onto forest floors and in lakes (Richerson et al, 1970;Proctor et al, 1996;Shumilovskikh et al, 2015), thus increasing the productivity of the ecosystem (Graham et al, 2006;Masclaux et al, 2013). The present study considers the ecological stoichiometry framework to relate data on pollen nutritional quality to the role of pollen in nutrient cycling within and between terrestrial and aquatic ecosystems.…”

“…The peat bog development was interrupted by two long dry phases between 2.3-2 ka and 1.6-1.2 ka, indicated by a decrease in Sphagnum-associated assemblages and an increase in pollen covered by fungal hyphae (Fig. 7), indicating stronger decomposition and mineralization of the peat by ectomycorrhizal or ericoid mycorrhizal fungi (Shumilovskikh et al 2015). Furthermore, a decrease in peat accumulation rate ( Fig.…”

The Ural Mountains are an important climatic and biogeographical barrier between European and Siberian forests. In order to shed light on the postglacial formation and evolution of the boreal forests in the European pre‐Urals, we obtained a peat sediment core, Chernaya, from the Paltinskoe bog located between the southern taiga and hemiboreal forest zone in the mid‐Kama region. We carried out pollen analysis, non‐pollen palynomorph analysis, loss‐on‐ignition tests and radiocarbon dating. Radiocarbon dated records provide centennial to decennial resolution of the vegetation and environmental history of the European pre‐Urals for the last 8.8 ka. The postglacial formation of the pre‐Uralian hemiboreal forests reveals four important phases: (i) the dominance of Siberian taiga and forest‐steppe in the Early Holocene and beginning of the Middle Holocene (8.8–6.9 ka), indicating a dry climate; (ii) the spread of spruce and European broadleaved trees in the Middle Holocene (6.9–4 ka) under wetter climate conditions; (iii) the maximum extent of broadleaved trees coinciding with the arrival and spread of Siberian fir in the Late Holocene (4–2.3 ka); and (iv) the decline of broadleaved trees since the Early Iron Age (2.3 ka – present) possibly due to general climate cooling and logging. While temperate broadleaved trees possibly spread from local refugia in the Urals, fir arrived from Siberia and spread further west. The carbon accumulation rate of Paltinskoe bog (18.9±10.16 g C m−2 a−1) is close to the average value of carbon accumulation of northern peatlands. Local development of peat is characterized by non‐gradual growth with a phase of intensive carbon accumulation between 3.5 and 2.3 ka. The vegetation was strongly influenced by fire in the Early Holocene and by humans since the Early Iron Age practicing deforestation, agriculture and pasture. Phases of increased anthropogenic activity correlate well with the local archaeological data.

“…The area around the bog appears to have been wooded continuously, as pollen records from the bog itself (Shumilovskikh et al, 2015;Schlütz unpublished) and the regional landscape history (Behre, 2008) suggest. The trees from these surrounding mineral soils would not be preserved, however.…”

Abstract. The investigated northwest German mire site at "Totes Moor" is densely covered with subfossil pine stumps (Pinus sylvestris L.) from the fen-bog transition. This facilitates the spatio-temporal reconstruction of mire development, which is based on 212 in situ tree stumps in the case study presented here. Six dendrochronologically dated site chronologies together cover 2345 years between 6703 and 3403 BC. The gaps in between are 6 to 550 years long. Additionally, a floating chronology of 309 years, containing 30 trees, was radiocarbon-dated to the beginning of the 7th millennium cal BC. Peat-stratigraphical survey was carried out additionally, and elevations a.s.l. were determined at several locations.Tree dying-off phases, which indicate water level rise at the site, mostly in context of the local fen-bog transition, are evident for ca. 6600-6450, ca. 6350-5750, ca. 5300-4900, ca. 4700-4550, ca. 3900-3850, ca. 3700-3600, ca. 3500-3450 and ca. 3400 BC. The spatial distribution of the dated in situ trees illustrates the phase-wise expansion of raised bog over fen peat at the site. The documented bog expansion pulses likely correspond to climatic wet sifts.
