Lake sedimentary records that allow documentation of the distinct climatic and environmental shifts during the early part of the Last Termination are scarce for northern Europe. This multi-proxy study of the sediments of Attek€ opsmosse, southwest Sweden, therefore fills an important gap and provides detailed information regarding past hydroclimatic conditions and local environmental responses to climatic shifts. Lake infilling started c. 15.5 cal. ka BP, but low aquatic productivity, cold summer lake water temperatures, unstable catchments, and scarce herb and shrub vegetation prevailed until c. 14.7-14.5 cal. ka BP. Inflow of warmer air masses and higher July air temperatures favoured a rise in aquatic productivity and lake water summer temperatures, and the establishment of a diverse herb, shrub and dwarf shrub vegetation, which also included tree birch c. 14.5 cal. ka BP. Freshening of the moisture source region c. 13.7-13.6 cal. ka BP does not seem to have had a large impact on the ancient lake and its catchment, as lake aquatic productivity increased further and lake water summer temperatures and minimum mean July air temperatures remained around 12-14°C. In contrast, further freshening of the moisture source region c. 13 cal. ka BP triggered a decrease in lake productivity, drier conditions and lower lake water summer temperatures. Macroscopic finds of tree Betula and Pinus sylvestris at 13-12.8 cal. ka BP demonstrate the presence of these trees in the lake's catchment. The transition into the Holocene (11.6-11.5 cal. ka BP) is marked by a change in chironomid assemblages and by a rise in lake water summer temperatures and aquatic productivity. These changes were followed by the re-establishment of a diverse aquatic and terrestrial vegetation, including tree birch and Pinus sylvestris at 11.4 cal. ka BP.

The immigration of woody plants, especially Betula (tree birch), is examined in relation to geomorphological regions in a compilation of Late-glacial plant macrofossil records from Denmark. The immigration of trees led to a large ecological transformation of the landscape and had a major effect on the flora and fauna available to Palaeolithic people. We show that soil type was a controlling factor in the development of vegetation during the Allerød and Younger Dryas periods. Following the first immigration of trees during the Allerød period, woods became established in the eastern part of Denmark, where ice advances from the Baltic had deposited calcareous and clayey sediments. The western and northern parts of Denmark that are characterised by more sandy and noncalcareous sediments remained treeless throughout the whole Late-glacial period. Finds from the Bromme Culture are concentrated in the region which was wooded, suggesting that the regional variable environment allowed local adaptations using the diverse resources available.

“…Betula pubescens (Bos 1998), but are much more tolerant to aridity (Miller and Wigand 1994;Willson et al 2008). Previous macrofossil finds, however, suggest that a likely representative of Juniperus was J. communis (Fischer et al 2013;Hartz and Milthers 1901;Mortensen et al 2011). Thereby the species acted as further soil preparer and did not grow above shrub height (Iversen 1973).…”

The exploration of Lateglacial vegetation history in Schleswig-Holstein is elaborate and comprehensive. Despite being one of the most studied areas, regarding to the Lateglacial, no biostratigraphy covering the complete Lateglacial and Early Holocene periods without hiatus have so far been recovered. In this paper we present a biostratigraphy of the Nahe palaeolake, therewith intending to deal with this desideratum.The special strength of the presented sequence is expressed in the fact that these are the only palynologically investigated sequentially annual laminated limnic sediments of the Lateglacial in Schleswig-Holstein. These laminated sediments, as well as radiocarbon dating of botanical macrofossils and three geochemically confirmed cryptotephra layers (Laacher See Tephra, Vedde Ash and Saksunarvatn Ash), provide excellent chronological control and allow for a Europe-wide correlation. Particularly important is a complete discussion of the vegetation history and the spatial proximity to Late Palaeolithic sites, which renders it possible to evaluate potential humanenvironment-interaction long before classical palynological human indicators occur. (2017) and radiocarbon ages of bones and antler suggest a temporal classification into the Dryas 3 period and partly into the early Preboreal period. Faunal remains have been investigated by WildFor that time, a ford situation can be reconstructed at the south-eastern end of the lake in the form of a shallow water area above a sand ridge, situated at the foot of the morain. The composition of the finds, antler technology as well as the topographical situation reflect a comparable situation as reconstructed for the Ahrensburg tunnel valley, located only 18 km to the south (Rust 1943; Rust and Gripp 1937). Materials and Methods Field methods and samplingThe coring took place in October 2017. A modified Livingston piston corer (Mingram et al. 2007)the so called Usinger-corerwas used to extract the sediment cores. Two overlapping sediment sequences with a diameter of 80 mm and a length of 16 m have been reached by drilling. Each 1-msegment was cut longitudinally, stored in PVC-liners and processed at the Institute for Pre-and Protohistoric Archaeology in Kiel, Germany. In order to connect the core sequences a series of distinct layers and stratigraphic marker horizons have been defined in the parallel cores. In this way, a composite core was constructed, representing a continuous record avoiding gaps (Dörfler et al. 2012).The interdisciplinary approach of the study required that the results of different methods could be correlated across depths. Therefore, a grid of 5 mm step size was created spanning the lower 5 m of the sequence. Each sample has been labelled according to consecutive numbers (953 potential samples in total, 11.10 m -15.89 m below the surface). A preliminary examination with 16 pollen samples determined the focus sequence for the analyses. The scope of the analyses is set on the sequence between sample 330 (12.745-12.750 m, ~10,030 cal yr BP) and 90...
