Tree-ring analyses were combined with observations of stem and root morphology, preservation state, mineral soil relief, peat stratigraphy and pollen analysis to reconstruct in great detail environmental changes leading to the start of the raised bog formation. Hydrology was identified as the main determinant influencing tree growth and population dynamics at Venner Moor, as documented by different growth patterns and dying-off dates in relation to the mineral soil elevation. The woodland phase has been dendrochronological dated to the period from 2421-2077 BC (4371-4027 cal BP). In this period, a general change from more or less open landscape with dominating heath to wet pine forest and eventually to open raised bog occurred at the site. Comparisons with pine population dynamics at the nearby Voerdener Moor and with the independent Lower Saxony log yak Chronology (LSBOC) indicate that the reconstructed ecological changes at Venner Moor are mainly triggered by climate variations, in particular wet shifts on the decadal timescale. This example shows the value of subfossil pine layers from northwest German bogs as a high resolution proxy archive of Holocene humidity fluctuations."],["dc.description.sponsorship","German Research Foundation [LE 1805/2-1]"],["dc.identifier.doi","10.1177/0959683609350397"],["dc.identifier.isi","000274900800008"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13085"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/20445"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0959-6836"],["dc.relation.orgunit","Abteilung Palynologie und Klimadynamik"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Dendroecological investigations at Venner Moor (northwest Germany) document climate-driven woodland dynamics and mire development in the period 2450-2050 BC"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

However, the role of such interactions is still underestimated or neglected in ecology and paleoecology. Here, we consider pollen attacked by fungi in palynological records from Holocene raised peat bogs as a nutrient source for ecosystems in the past. The attacks occurred through the pollen germination areas by a variety of saprotrophic, ericoid mycorrhizal, ectomycorrhizal or dark septate endophyte fungi. Large amounts of attacked pollen in phases rich in Calluna vulgaris highlight the importance of Ericaceae shrubs, hosting ericoid mycorrhizal fungi and forming hotspots of decomposition in nutrient-deficit bogs. Applying estimations of pollen rain from literature, and based on own observed pollen infection rates we estimate the annual release of nitrogen, phosphate and potassium from pollen, and highlight their significance in pushing the ecosystem nutrient cycle in early spring time, when several species release their pollen. We highlight the significant role of anthropogenic changes in pollen deposition for pre-industrial bogs and hypothesize about the consequences of the pollen-based interrelation between wind-pollinated plants and their mycorrhizal fungi in paleoecology and evolution.
