“…As mentioned before, the dying-off phases observed at TOMO_south show much synchronism with dying-off phases observed at other mire sites in northwest Germany (Eckstein et al, 2009(Eckstein et al, , 2010(Eckstein et al, , 2011, which emphasizes their climatic context. In addition to the temporal placing of the TOMO_south record (terminating 3400 BC) and its location in the northwest German lowland, where settlements were established later than on the richer soils of the adjacent hills, this synchrony makes it appear unlikely that anthropogenic clearance activity in the catchment area might have had a detectable influence on the bog's hydrology.…”

“…This has been found evident on base of abundant upward growing roots late in the tree's life, the drastically narrowing rings near the bark, peat stratigraphical context and the state of conservation at various comparable sites investigated in northwest Germany and southern Sweden (Eckstein et al, 2009(Eckstein et al, , 2010Edvardsson et al, 2012bEdvardsson et al, , 2014Leuschner et al, 2002Leuschner et al, , 2007. Therefore the death of the trees and their conservation under Sphagnum peat dates raised bog expansion, and using in situ stumps adds location to the event.…”

“…They were able to show that the tree dying-off is mostly due to hydrological changes, while fire and storm have been found to be of little relevance on the investigated sites. Particularly the observed synchrony of pine establishment and dying-off phases in different mires shows that the local mire development documented by the trees is strongly linked to climatic variations (Eckstein et al, 2009(Eckstein et al, , 2010(Eckstein et al, , 2011Edvardsson et al, 2012a, b).…”

“…The trees dated absolutely by dendrochronology deliver the finest temporal reconstruction of bog expansion and local bog formation, particularly by their dying-off dates (Eckstein et al, 2009(Eckstein et al, , 2010Edvardsson et al, 2014Edvardsson et al, , 2016Krąpiec et al, 2016;Leuschner et al, 2002Leuschner et al, , 2007. Eckstein et al (2009Eckstein et al ( , 2010Eckstein et al ( , 2011 have shown that the tree dying-off occurs in phases, which are often synchronous in different mires.

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.

“…Similarly to Vaupell, many of these studies concentrate on the growth of the bog pines in relation to past climate variability (Leuschner et al, 2007;Eckstein et al, 2009;Moir et al, 2010;Edvardsson et al, 2012). Some of the megafossil studies have likewise interpreted the growth patterns and the shapes of the tree-ring curves in the context of the environmental changes through time (Spurk et al, 2002;Helama et al, 2005;Schaub et al, 2008).…”

Abstract. Christian Theodor Vaupell (1821-1862) was a Danish scholar with pioneering investigations particularly on the late Quaternary development of bog forests, but also microscopy of plant anatomy and vegetative reproduction. His studies contributed to the early scientific thinking of the Quaternary environmental changes. Before his academic efforts, he had already survived the war between Prussia and Denmark albeit he became severely wounded and his left arm was amputated. The drama of his academic efforts, on the other hand, lies in the more or less suspicious dispute of his first doctoral thesis and his dismissal from the academic world during the following years. At the same time, he earned praise for his first thesis (never accepted as thesis but published as a regular book) from abroad; he was also able to attract private foundations for financial support of his scientific work. Following the enthusiasm of his time, Vaupell became attracted to the pine megafossils known to have been preserved in the bogs in north-west Europe. The megafossils led him to study not only the life systems of the ancient and modern bog forests but also their associations with Earth processes. As an interesting detail of his research, Vaupell made compound interpretations on the occurrence of megafossil stumps and their tree-ring growth patterns. In the course of the 20th century, Vaupell's studies have been cited as a general reference of post-glacial vegetation change and plant succession rather than clearly pioneering investigations of palaeoecology, an angle that we would like put into a contrasting perspective. To do so, we provide a brief portrait of Christian Vaupell and his research career. In conclusion, we wish to emphasize the comprehensiveness of Vaupell's views on the late Quaternary vegetation changes and the role of plant succession in that development. School days, early studies and military serviceChristian Vaupell was born in Kolding, Denmark, 14 October 1821, the son of Lieutenant colonel Johan Wilhelm Ludvig Vaupell and wife Margrethe Dorthea Karberg. Christian Vaupell attended the local school of which he remembered with gratitude. Seeds of inspiration were sown by those school teachers that were enthusiastic and keen to educate the pupils. Bryndum taught in history and geography, and Borgen guided the pupils out to botanize. During vacations, Christian Vaupell contributed with specimens to L. Hansen's herbarium in the duchies of Holstein and Schleswig.By completing examen atrium in 1841, Vaupell qualified for admission to the university, where he became deeply interested in the societies of the antiquity and their relationship to the modern society, as well as theology. Vaupell took the examen philosophicum, and later received the academic degree candidatus theologiae, from the University of Copenhagen in 1847. Shortly after, he continued with botany and obtained insights into the other natural sciences. He attended the lectures by Prof. Johan Georg Forchhammer about the geological periods and their flor...

Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in a South Swedish peat deposit. In combination with peat stratigraphy, this approach was explored for its potential to provide information on the local hydrological and depositional history at the site, forming the basis for a regional palaeohydrological analysis. A 726-year ring-width chronology was developed and assigned an absolute age of 7233-6508 cal a BP (5284-4559 BC) through cross-dating with German bog-pine chronologies, whereas two short additional records of older ages were radiocarbon dated. Registration of growth positions of individual trees allowed assessment of the spatial dynamics of the pine population in response to hydrological changes and peatland ontogeny. Annually resolved growth variability patterns in the pine population reveal several establishment and degeneration phases, probably reflecting fluctuations in bog-surface wetness. A major establishment phase at 7200-6900 cal a BP reflects the onset of a period of lowered groundwater level, also indicated by increased peat humification, and a development consistent with regional temperature and lake level reconstructions revealed from other proxies. This study demonstrates that subfossil bog-pine populations may provide annually to decadally resolved reconstructions of local groundwater variability, which are highly relevant in a long-term palaeoclimatic context.
