Fredskild, B. Holocene palaeo-winds and climatic changes in West Greenland as indicated by long-distance transported and local pollen in lake sediments. In Mörner, N.- In Mörner, N.- A. and Karlén, W., editors, Climatic changes on a yearly to millennial basis, Dordrecht: Reidel, – Three short-lasting vegetational set-backs at ca , and ka b.p. may indicate climate oscillations. A temporary reduction of local forests reflects the Erdalen 2/ka b.p. event.
This paper discusses pollen, charcoal and peat‐stratigraphic evidence for major local vegetation changes and for the development of the surrounding cultural landscape during the last radiocarbon yr. Pollen data from one of the sites (BYC 2) provided a vegetational record for most of the Holocene. The close chronological control permits the correlation of key vegetational changes with those at other reliably dated sites in the eastern Dakotas and in Minnesota, suggesting that the abrupt decline of the spruce forest was time-transgressive from southwest to northeast during yr, and that the development of prairie was time.
In hunters' Stone Age, occurred the hottest time throughout the Holocene, which is called the Holocene Optimum, and lasted almost until the Neolithic period about 4, years before present, then the temperature continued to drop through bronze-, iron-age and historical times until it reached a low point in the Little Ice Age in 's. The Younger Dryas (aro to 11, years BP) was a return to glacial conditions after the Late Glacial Interstadial, which temporarily reversed the gradual climatic warming after the Last Glacial Maximum (LGM) started receding aro BP. It is named after an indicator genus, the alpine-tundra wildflower Dryas octopetala, as its leaves are occasionally abundant in late glacial.

Cite by: A pollen diagram from a site in the Esbjerg area, western Denmark, is used for reconstruction of the Holocene vegetational and environmental history there. During the Atlantic there was a parallel development of the landscape to that of other areas in Jylland (Jutland).
From the late Neolithic onwards the development took its own course related to the approaching North Sea, which periodically Author: Else Kolstrup. Palaeoecological studies of lake sediments in west Greenland were pioneered by Iversen (), and followed by Fredskild,Fredskild,Fredskild, b, Böcher and Fredskild (), Bennike ()and Eisner et al.

Holocene sediments of three closed Danish lake basins (Solsø, Skånsø, Kragsø) were used for the inference of post‐glacial vegetational dynamics in former heathland areas in northern West Jutland, Denmark.
The sites were selected to represent the major geomorphological units of West Jutland. Holocene climatic, vegetational and environmental changes on the Ammassalik Island in SE Greenland ( N and W) have been studied in lake sediments and soil profiles. Based on the stratigraphy of sediments, geobiochemical characteristics, pollen and other biological proxies, a.
The sensitivity of this land‐based Greenland Ice Sheet (GrIS) sector to abrupt climatic change suggests the ice margin was in nearequilibrium with climate throughout the Holocene. Because the GrIS in this area is not heavily influenced by ice dynamics (e.g., calving; Csatho et al., ) and the ice margin has a relatively short response time.
A cm long sediment sequence was recovered from the unofficially named Raffles Sø on Raffles Ø, outer Scoresby Sund region, East Greenland. The sediment sequence consists in the upper part (0– cm) of a stratified gyttja enriched in organic carbon and biogenic silica whereas the lower core part (– cm) is composed of terrigenous, consolidated glacio-limnic sediments.

Po Diatom and lithological analyses were carried out on two sediment cores from Disko Bugt and the adjacent Kangersuneq Fjord, West Greenland, in order to investigate mid-to late-Holocene ( kyr BP) hydrographic and climatic variability. Holocene sediments of three closed Danish lake basins (Solsø, Skånsø, Kragsø) were used for the inference of post-glacial vegetational dynamics in former heathland areas in northern West.
Many studies have focused on Holocene vegetation change in central Asia and its implications for the evolution of humidity over a large area (An et al., ; Chen et al., ; X.
Huang et al.,; Liu et al., ; X. Sun et al., ; Tarasov et al.,). However, most of the lake sites are in basins at lower altitudes. There are three main periods of change in the post-settlement vegetational development of the area.
Firstly, Norse settlement affected the hydrology of the bog, resulting in the near-disappearance of Sphagnum and agricultural activity led to a reduction of some species (e.g. Angelica spp. and Salix).

Macrofossil analyses were carried out on the late-glacial and early-Holocene sediments of the radiocarbon-dated master core at Kråkenes Lake, western Norway, to investigate the aquatic vegetation changes. Ranunculus sect. Batrachium and Nitella were the earliest pioneers after deglaciation ca.
12, 14C yr BP. The Allerød vegetational succession was very slow during ca. .This sequence of wetland development did not match the present vegetational gradients from Carex–Typha herb marsh, through Myrica–Decodon shrub marsh and Alnus–Fraxinus thicket, to Thuja swamp.
At this site, the wetland development was mainly influenced by allogenic factors such as water levels and climate rather than autogenic factors. We conducted high-resolution palynological analysis on a sediment core obtained from Lough Muckno, County Monaghan, Ireland.
The results presented represent the first paleoecological account of Mid-Late Holocene vegetational change and land-use dynamics in the study region. Human activity and agriculture is first recorded during the Early Neolithic (ca.
