Climate variability and associated vegetation response throughout Central and Eastern Europe (CEE) between 60 and 8 ka
- Abstract Records of past climate variability and associated vegetation response exist in various regions throughout Central and Eastern Europe (CEE). To date, there has been no coherent synthesis of the existing palaeo-records. During an \INTIMATE\ meeting (Cluj Napoca, Romania) focused on identifying \CEE\ paleo-records, it was decided to address this gap by presenting the palaeo-community with a compilation of high-quality climatic and vegetation records for the past 60–8 ka. The compilation should also serve as a reference point for the use in the modelling community working towards the \INTIMATE\ project goals, and in data-model inter-comparison studies. This paper is therefore a compilation of up to date, best available quantitative and semi-quantitative records of past climate and biotic response from \CEE\ covering this period. It first presents the proxy and archive used. Speleothems and loess mainly provide the evidences available for the 60–20 ka interval, whereas pollen records provide the main source of information for the Lateglacial and Holocene. It then examines the temporal and spatial patterns of climate variability inferred from different proxies, the temporal and spatial magnitude of the vegetation responses inferred from pollen records and highlights differences and similarities between proxies and sub-regions and the possible mechanisms behind this variability. Finally, it identifies weakness in the proxies and archives and their geographical distribution. This exercise also provides an opportunity to reflect on the status of research in the area and to identify future critical areas and subjects of research.

Landwirtschaft und Landnutzung in der Region von Ovčarovo-Gorata: archäobotanische Forschungen zum Frühneolithikum in Nordostbulgarien
- There is no archaeobotanical evidence from the site Ovčarovo-Gorata. During the excavations of the site in the 1970ties neither archaeobotanical sampling nor survey for pollen analysis in the surrounding were conducted. Those research gaps could partly be compensated by the archaeobotanical studies on the Neolithic settlements of Orlovec, Koprivec, Samovodene und Džuljunica carried out in the period of 1996-2006. The paleobotanical evidence from those sites allows to reconstruct the agriculture and land use in the region of Ovčarovo-Gorata during the Neolithic and to put them in a regional context. The current study is based on identification and analysis of charred (and few mineralised) plant remains, like seeds/fruits and charred wood. Those plant remains were extracted from the sediment samples (average volumes 10-20 litre) using manual floation. The here considered archaeobotanical data includes 31 samples, with total volume of 430 l and containing over 2400 identified plant remains. The archaeobotanical finds were analysed with the help of binocular and reflected light microscope, as well as corresponding identification literature and reference materials from the herbarium at the Department of Botany of the Sofia University. The early Neolithic samples from Džuljunica, Orlovec and from the oldest layers of Koprivec could be considered as synchronous and belong to the earliest phase of the Neolithic in the region (ca. 6100-5700 calBC). The samples from the early Neolithic layers of Samovodene (horizon 11-8) belong to the developed early Neolithic and are considered as contemporary with the period Karanovo II in Thrace and correspondently to the occupation of Ovčarovo-Gorata (ca. 5700-5400 calBC). Few of the samples (n=4) come also from the Late Neolithic (ca. 5400-4800 calBC) in the region, from Samovodene (horizon 5-3) and from Koprivec. The results of the archaeobotanical studies show the combination of the three main cereal crops (einkorn, emmer and barley) known also from the early Neolithic of Thessaly and Anatolia. In the samples from northeast Bulgaria the dominating cereal crop is the hulled barley, what is a clear difference from the southern parts of Bulgaria where in the early Neolithic the dominating cereal crops are hulled wheats – einkorn and emmer. The further principal crops, typical for the Neolithic period, are also found in the earliest phases of the Neolithic in the region. Those are a variety of pulses (lentil, pea and grass pea) as well as flax. In the late Neolithic samples there are also finds of bitter vetch. The wide spectrum of gathered plants (at least 11 taxa) reflects also the use of the natural vegetation resources from a variety of habitats in the surrounding. Further evidence which could be used for reconstructing the vegetation and land use in the Neolithic are the wood charcoal identifications from Džuljunica. Considering those sources of information it could be concluded that in the surrounding of the sites apart of oak forests also open vegetation, riparian forests and wetlands were developed. The relative open vegetation in the surrounding of the early Neolithic settlements could be one of the reasons why the corresponding locations were chosen by the Neolithic people to settle there. On the other hand this open vegetation could be caused by the Neolithic land use and animal husbandry, which have also led to certain reduction of the forests in the immediate surroundings of the settlements.

Crop diversity and choices in the prehistory of SE Europe: the archaeobotanical evidence from Greece and Bulgaria
- The paper outlines a general pattern regarding crops and their diversity in northern Greece and Bulgaria, and set our observations in relation, where possible, to other areas of the Balkans. Although at present our body of data is not uniformly rich and reliable for comparisons between different periods within the Neolithic and the Bronze Age to be made, it has been possible to roughly draw a picture of crops for these two broad periods and to compare the archaeobotanical evidence between certain parts of southeastern Europe. Thus, several common trends have been identified or re-confirmed, such as the predominance of the glume wheats, the important role of pulses, the clear visibility of flax and the introduction of various crops during the Bronze Age, probably through cultural contacts. At the same time, several interesting differences are beginning to emerge and in the future would be worth exploring further on the basis of more archaeobotanical data: the predominance of einkorn in certain parts of Bulgaria and in many sites of northern Greece, the appearance of free-threshing wheat as a crop on the Black Sea coast of Bulgaria during the Chalcolithic, the presence of chickpea in the later phases of the Early Neolithic of southern Bulgaria, the absence of Celtic bean and millet in the Neolithic in both regions, and the total absence of a wide range of crops encountered in Greece during the Bronze Age, in particular oil, medicinal and hallucinogenic plants. It is evident that many crops are common in this part of southeastern Europe, shared among the different cultures for a considerable length of time. At the same time, certain areas are slightly different and in the future we need to consider the broader cultural context and environments of these areas to understand divergences in the crop pattern. Such observations would also greatly benefit from a consideration of a wide range of environmental factors, particular to individual sites or regions, which may have interacted with human choices as regards the crops on which they relied. Moreover, independent information from palaeoclimate proxies (as, for example, the δ13C measurements) and models could help us to clarify climate-driven change in crop diversity.
