Abstract. This paper investigates the Holocene vegetation dynamics for Burmarrad in Northwest Malta and provides a pollen-based quantitative palaeoclimatic reconstruction for this centrally located Mediterranean archipelago. The pollen record from this site provides new insight into the vegetation changes from 7280 to 1730 cal BP which correspond well with other regional records. The climate reconstruction for the area also provides strong correlation with southern (below 40° N) Mediterranean sites. Our interpretation suggests an initially open landscape during the early Neolithic, surrounding a large palaeobay, developing into a dense Pistacia scrubland ca. 6700 cal BP. From about 4450 cal BP the landscape once again becomes open, coinciding with the start of the Bronze Age on the archipelago. This period is concurrent with increased climatic instability (between 4500 and 3700 cal BP) which is followed by a gradual decrease in summer moisture availability in the late Holocene. During the early Roman occupation period (1972–1730 cal BP) the landscape remains generally open with a moderate increase in Olea. This increase corresponds to archaeological evidence for olive oil production in the area, along with increases in cultivated crop taxa and associated ruderal species, as well as a rise in fire events. The Maltese archipelago provides important insight into vegetation, human impacts, and climatic changes in an island context during the Holocene.

Systematic excavation at Gomolava conducted almost interruptedly between 1953 and 1985 provided an almost full insight into the human occupation of the southern Pannonian Plain from the Early Neolithic to the successive arrival of Celts and Romans. This fact makes it possible for many of the excavated short-lived or horizontally-stratified settlements to be defined in relation to Gomolava's stratigraphic sequence. As a result, the paper attempts to establish a relative chronology for Bronze and Iron Age sites in the area between the Sava and Danube rivers. By way of illustration, it offers four maps suggesting synchronous developments. Thus Map 1 shows chronological parallelism between the Early Bronze Age layers and late Vucedol and Vinkovci sites (such as Pecine near Vrdnik, or Belegis, Vojka and Batajnica) belonging to the final Eneolithic and Early Bronze, while Map 2 shows synchronisms between Gomolava IVb-c and the Vinkovci layers at the sites of Gradina on the Bosut, Gradac at Belegis, Petrovaradin Fortress, and Asfaltna Baza on the outskirts of Zemun. The end of the Bronze Age represented by Gomolava IVb1 to IVc is shown to be synchronous with the settlements, necropolises and hoard horizons of an Ha A1 and A2 date. Finally, Early Iron Age sites are easy to fit in with the Srem sites owing to systematic excavations at Gradina on the Bosut near Sid, Kalakaca near Beska and numerous hoards of bronze artefacts marking a clear boundary between the Bronze and Early Iron Ages. At Gomolava this transition is reflected in horizons Va to Vd: the earliest is represented by black channeled pottery of the Gava type, while the other three are connected with the evolution of the Bosut-Basarabi complex.

AbstractKnowledge about the vegetation history of Sardinia, the second largest island of the Mediterranean, is scanty. Here, we present a new sedimentary record covering the past ~ 8,000 years from Lago di Baratz, north-west Sardinia. Vegetation and fire history are reconstructed by pollen, spores, macrofossils and charcoal analyses and environmental dynamics by high-resolution element geochemistry together with pigment analyses. During the period 8,100–7,500 cal bp, when seasonality was high and fire and erosion were frequent, Erica arborea and E. scoparia woodlands dominated the coastal landscape. Subsequently, between 7,500 and 5,500 cal bp, seasonality gradually declined and thermo-mediterranean woodlands with Pistacia and Quercus ilex partially replaced Erica communities under diminished incidence of fire. After 5,500 cal bp, evergreen oak forests expanded markedly, erosion declined and lake levels increased, likely in response to increasing (summer) moisture availability. Increased anthropogenic fire disturbance triggered shrubland expansions (e.g. Tamarix and Pistacia) around 5,000–4,500 cal bp. Subsequently around 4,000–3,500 cal bp evergreen oak-olive forests expanded massively when fire activity declined and lake productivity and anoxia reached Holocene maxima. Land-use activities during the past 4,000 years (since the Bronze Age) gradually disrupted coastal forests, but relict stands persisted under rather stable environmental conditions until ca. 200 cal bp, when agricultural activities intensified and Pinus and Eucalyptus were planted to stabilize the sand dunes. Pervasive prehistoric land-use activities since at least the Bronze Age Nuraghi period included the cultivation of Prunus, Olea europaea and Juglans regia after 3,500–3,300 cal bp, and Quercus suber after 2,500 cal bp. We conclude that restoring less flammable native Q. ilex and O. europaea forest communities would markedly reduce fire risk and erodibility compared to recent forest plantations with flammable non-native trees (e.g. Pinus, Eucalyptus) and xerophytic shrubland (e.g. Cistus, Erica).

Despite the important roles that horses have played in human history, particularly in the spread of languages and cultures, and correspondingly intensive research on this topic, the origin of domestic horses remains elusive. Several domestication centers have been hypothesized, but most of these have been invalidated through recent paleogenetic studies. Anatolia is a region with an extended history of horse exploitation that has been considered a candidate for the origins of domestic horses but has never been subject to detailed investigation. Our paleogenetic study of pre- and protohistoric horses in Anatolia and the Caucasus, based on a diachronic sample from the early Neolithic to the Iron Age (~8000 to ~1000 BCE) that encompasses the presumed transition from wild to domestic horses (4000 to 3000 BCE), shows the rapid and large-scale introduction of domestic horses at the end of the third millennium BCE. Thus, our results argue strongly against autochthonous independent domestication of horses in Anatolia.

This paper presents the results of the first investigation of vegetation change and human activity from a river valley west of the Somerset Levels. The record is contrasted with the pollen and archaeological record from south-west uplands (Dartmoor and Exmoor) and the Somerset Levels. Vegetation change and archaeological evidence are shown to be generally consistent, with evidence from the middle valley of Mesolithic vegetation disturbance (with nearby lithics), Neolithic clearance of terraces and slopes in the lower valley and Neolithic–Bronze Age ceremonial and domestic activity, but in the upper reach the maintenance of wooded valley floor conditions probably with management until historic times. The valley floor and surrounding slope vegetation history is found to be significantly different to that of the uplands with lime and elm being significant components of the prehistoric woodland record. The data suggest that lime is restricted to terraces and lowlands below 200 m OD throughout the prehistoric period. The pollen data from the valley suggest the lowlands had a rich and mixed ecology providing a wide range of resources and that, despite less visible archaeological remains, human activity is manifest through palynological evidence from the Mesolithic to the Bronze Age. The largest expanse of valley-floor terrace, the Nether Exe Basin, which was at least partially deforested in the early Neolithic contains a rich assemblage of Neolithic–Bronze Age ceremonial, funerary and domestic archaeology associated with an early and clear palynological record of woodland clearance, arable and pastoral activity.

AbstractVegetation changes are reconstructed based on more than 51,000 charcoal fragments of more than 380 samples from nine Bronze Age sites in northern Syria and southern Turkey. In addition to fragment proportions, special attention was paid to the frequency of Pistacia relative to Quercus and Populus/Salix relative to Tamarix, fruit-tree ubiquity, and riverine diversity in order to gain an improved understanding of the human versus climatic impact on the vegetation. The results indicate that human impacts first took place within the riverine forest. This phase was followed by land clearing within the woodland steppe, especially in the northern portion of the study area. In the south near Emar, the woodland steppe probably disappeared by the Late Bronze Age. It is uncertain whether this was caused by aridification and/or human clearing. The northward shift of the Pistacia-woodland steppe is very likely a result of climatic drying that occurred throughout the entire period under investigation. Although increased deforestation is evident through time, the small proportions of imported wood indicate that local resources were still available.

AbstractDuring several archaeological excavations on a river terrace of the river Meuse near the village of Lomm (southeast Netherlands) information was gathered for a reconstruction of the sedimentation and vegetation history during the Holocene. Various geoarchaeological methods – geomorphological, micromorphological and botanical analyses – were applied, while accelerator mass spectrometry (AMS) 14C and optically stimulated luminescence (OSL) dating provided an accurate chronology for the sediments.During the Early Holocene, many former braided river channels were deepened due to climate amelioration. Later, river flow concentrated in one main river channel to the west, at the location of the modern Meuse. The other channels were only active during floods, and infilling continued until the Bronze Age. Because of the higher setting of the Lomm terrace, it was only occasionally flooded and therefore formed an excellent location for habitation. Humans adapted to the changing landscape, as most remains were found on the higher river terraces or their slopes, a short distance from the Maas river. The Lomm terrace was more or less continuously inhabited from the Mesolithic onwards.During the Early Holocene, river terraces were initially densely forested with birch and pine. From the Boreal (Mesolithic) onwards, dense mixed forests with deciduous shrubs and trees such as hazel, oak, elm and lime developed. During the Atlantic (Meso/Neolithic), the deciduous forests became dominated by oak. Due to human activities from the Late Subboreal (Late Bronze Age) onwards, forests slowly became more open, yet remained relatively dense in comparison to other Dutch areas. The botanical data, however, show that within the Lomm study area there was a large difference in the composition, distribution and openness of the vegetation. The spatial variation in openness came into existence during the Late Bronze Age, as soon as the higher areas started to be used for human activities (i.e. habitation, agriculture and livestock herding). Due to human activities, the northern part of the study area became very open during the Early Roman period. In the lower-situated areas of the southern part, however, forests remained present much longer, until the Early Middle Ages. Due to large-scale deforestation in the Lomm area and hinterland during the Roman period and Middle Ages, the sediment load of the river increased, large floods occurred and overbank sediments were deposited, burying the archaeological remains. The largest increase in sedimentation occurred after the Middle Ages.

It is rare for authors to be able to read comments on their paper by leading colleagues and to have the chance to respond before its publication. We would like to thank the editor of Antiquity for providing this opportunity. The comments express both acceptance of, and doubts about, interconnectedness between the eastern Mediterranean and Scandinavia in the Bronze Age. Kaul's comments demonstrate a deep insight into how Nordic archaeology reveals this interconnectedness; that is clearly expressed in his latest publication on the topic in Antiquity (Kaul 2013). Moreover, both Kaul and Sognnes, who accept these interconnections, have an excellent understanding of Scandinavian Bronze Age rock art. In fact, most of the reviewers’ comments express a positive attitude to the interpretation of the rock art images as possible representations of oxhide ingots.

Thessaly in Central Greece is famous for settlement mounds (magoules) that were already partly formed in the Early Neolithic period. Some of these long-lived sites grew to many metres in height during the subsequent Middle, Late and Final Neolithic periods, and were also in­habited in the Bronze Age. Such magoules served as the backbone for defining relative chronolo­gical schemes. However, their absolute dating is still a topic of debate: due to a lack of well-defined se­quences, different chronological schemes have been proposed. New radiocarbon dates obtained in the last few years allow a better understanding of the duration not only of the main Neolithic pe­riods, but also of the different phases and sub-phases.

The archaeological research focusing on El Mirador Cave (Sierra de Atapuerca, Spain) has revealed a succession of occupation levels in a dung layers context that span from the early Neolithic to the middle Bronze Age. The robustness and coherence of the chronological dates of the sequence have contributed to framing the beginning of farming practices on the northern Plateau of the Iberian Peninsula. This study focuses on the palynological analysis of the sedimentary sequence, spanning from ca. 7970–7770 to ca. 3390–3070 cal. yr BP. The results have allowed us to identify a landscape of mixed forest with evergreen and deciduous oaks and pinewood. Despite the discontinuities in such sediments, some fluctuations between different categories of anthropogenic taxa can be observed throughout the sequence, illustrating greater or lesser pressure from livestock or agriculture. From the Neolithic to the Bronze Age, we documented a reduction in the tree cover because of increased human pressure typical of the Neolithisation process, while the relationship between environment and society changes.
