The Pyrenean Lake Montcortès sediments hold the longest continuous and absolutely varve-dated record of the Mediterranean region, encompassing the last three millennia, from the Late Bronze Age to the present. The reconstruction of vegetation and landscape dynamics during this time period has advanced gradually, following the progress of absolute dating by varve counting, and has been progressively published and updated in a number of papers dealing with specific time intervals at different temporal resolutions. This paper synthesizes all these studies in a single composite paleoecological sequence constrained by a single age-depth varve model. The final resolution of this reconstruction is bidecadal, on average, but some periods have been resolved at quasidecadal (Middle Ages) and subdecadal (Modern Age to present) resolutions. The study is focused on the timing of anthropization and the further development of vegetation under climatic and anthropogenic drivers until the shaping of present landscapes. An additional advantage of Montcortès is that the local history of the Pallars region, where the lake is located, is well documented and can be easily correlated with the paleoecological record. Contrary to former interpretations of general landscape anthropization of the Pyrenees during the Middle Ages, the Montcortès catchment was irreversibly transformed by anthropic activities at the beginning of the Iron Age (ca. 750-650 BCE). From this point, the catchment underwent successive transformations due to varied human uses (fire, grazing, cereal cultivation, weed/ruderal plant expansions, hemp cultivation/retting), which have been related to the different cultural phases and sociopolitical changes documented in the local historical records. The regional forests, dominated by Pinus and Quercus, experienced four main clearance events (RD) during the Iron Age (RD1; ca. 300 BCE), the Roman Period (RD2; ca. 300 CE), the Middle Ages (RD3; ca. 1000 CE) and the Modern Age (RD4; ca. 1800 CE). The detailed trends of the last two deforestation events and their causes could be studied at a decadal resolution, which significantly improved interpretation quality in ecological terms. The potential effects of climatic changes and the eventual interactions with human activities on catchment vegetation and regional forests throughout the record have also been discussed. The Montcortès record has been compared with other records at local (Pyrenees), regional (Iberian Peninsula) and biome (Mediterranean) scales. Locally and regionally, anthropization times and further ecological trends showed significant heterogeneity according to elevation, biogeographical patterns and cultural trends. The most significant coincidence is an intensification of human pressure, as noted in forest clearing and extensive land use, during several phases of the Middle Ages. At the Mediterranean level, the Montcortès record emerges as a unique sequence for the western sector of this biome that should be complemented with similar archives from the central and eastern Mediterranean. The most promising candidates for such sequences are discussed on the basis of available Mediterranean varved records.

Palynological analysis of the last ca. 4300 cal year BP using a sediment core taken from high mountain (ca. 1900 m elevation) Lake Sant Maurici sediments (southern-central Pyrenees) showed remarkable vegetation constancy during the Bronze Age and the Middle Ages. Records of the Iron Age and the Roman period were missing due to a major sedimentary gap. During the studied periods, the vegetation around the lake was largely dominated by pine ( Pinus) forests with birch ( Betula), oak ( Quercus) and hazel ( Corylus) trees, as is the case today. The composition of these forests and the abundance of their components remained quite stable, despite the occurrence of temperature and moisture shifts. The degree of human disturbance, notably that of pastoralism and cereal cultivation by scattered and temporary settlements, was very low and had little or no effect on the dominant forests. This situation contrasts with most high-elevation (subalpine and alpine) environments of the central Pyrenees that were massively anthropized during the Middle Ages. Further research should be aimed at finding sediments corresponding to the Iron Age and the Roman period to verify whether the vegetation constancy can be extended throughout the Late-Holocene. Past records of this type may allow the estimation of natural and anthropogenic thresholds for irreversible forest changes, which would be useful for conservation purposes.

The article is devoted to the publication of finds of fragments of ceramic dishes discovered at the settlement of Pestryakovo Lake (Zavyalovsky district of Altai Territory). A group of ceramics which belongs to the early Iron Age and the Middle Ages, is pointed out. Single fragments find analogies in the materials of the sites of the Early and Late Bronze Age. The ceramic collection of the Pestryakovo Lake settlement includes groups of ceramics that belong to the Neolithic or Eneolithic. These are fragments of vessels ornamented with prints of a “string”, pricks, imprints of a short comb stamp, a dingle-dingle stamping. Linear-pricked and receding-pricked ceramics are quite informative. On the outer and inner surfaces, as well as in the fractures, traces of burnt-out organic matter (animal hair) are recorded. Such ceramics are widely represented in the south of Western Siberia and are associated with various settlement and burial complexes from the Ob to the Irtysh and various cultural formations of the Neolithic and Eneolithic.

Past Pleistocene topography of the loess uplands is rich in local sinks (closed depressions (CDs)) influencing sediment fluxes. Soil-sediment sequences from CDs constituting geoarchives where landscape changes under natural and anthropogenic conditions have been recorded. Pedo-sedimentary archives from 10 CDs in the Polish loess belt and human settlements were analysed. Phases of the Holocene evolution of the CDs were correlated with landscape dynamics in loess areas in Poland and Central Europe. Phases of infilling of CDs occurring (2) from the late Boreal/early Atlantic Period until the (middle) late Bronze Age/early Iron Age and (4) since the early Middle Ages until today were documented. These were phases of long-term soil erosion and colluviation corresponding to the increasing agricultural land use of Polish loess uplands. Phases of soil formation related to geomorphic stabilization of CDs occurred (1) from the late Vistulian until the late Boreal/early Atlantic Period and (3) from the late Bronze Age/early Iron Age until the early/high Middle Ages. These were phases of decreased soil erosion and landform conservation in a considerable part of Poland’s loess areas. Pedo-sedimentary archives from the CDs have recorded soil erosion strongly related with human-induced land-use changes. The mean soil erosion rate in the catchment of CDs was 0.33 t·ha−1·yr−1 during prehistory and 4.0 t·ha−1·yr−1 during the last approximately 1000 years. Phases of CD evolution are representative for the main phases of sediment and landscape dynamics in Poland’s loess areas recorded in various archives, and are not synchronous with some of these phases in Central Europe.

Colluvial deposits, as the correlate sediments of human-induced soil erosion, depict an excellent archive of land use and landscape history as indicators of human–environment interactions. This study establishes a chronostratigraphy of colluvial deposits and reconstructs past land use dynamics in the Swabian Jura, the Baar and the Black Forest in SW Germany. In the agriculturally favourable Baar area multiple main phases of colluvial deposition, and thus intensified land use, can be identified from the Neolithic to the Modern times. In the unfavourable Swabian Jura increased colluvial deposition began later compared to the more favourable areas in the Baar. The same holds true for the unfavourable areas of the Black Forest, but intensified land use can only be reconstructed for the Middle Ages and Early Modern times instead of for the Bronze and Iron Age as in the Swabian Jura. Land use intensity and settlement dynamics represented by thick, multilayered colluvial deposits increase in the Baar and the Black Forest during the Middle Ages. In between those phases of geomorphodynamic activity and colluviation, stable phases occur, interpreted as phases with sustainable land use or without human presence.

Why did Christianity decline relatively to Islam in wide areas of the Mediterranean world during the European Middle Ages? The problem has deserved more attention than it has received from historians, for the pattern is not a consistent one and the decline where it took place, cannot be explained on the grounds of Moslem military superiority alone. The first generation of Moslem conquerors that so decisively defeated the Byzantine armies were plunderers who sought booty and revenge for past wrongs suffered at the hands of the Byzantine authorities or simply from the agricultural and urban populations of the east Roman frontier provinces. Confronted with undreamed of success, they had little idea of establishing either civil government or settling in the areas they had conquered. They had little desire also to convert their new Christian subjects, for that would diminish the flow of tribute exacted in exchange for protection. Yet as time went on, Christianity in the eastern Mediterranean showed none of the survival and recuperative power that characterised the Orthodox Church in the Balkans during the five centuries of Ottoman occupation from 1390–1912. Of the areas overrun by successive Moslem invaders down to 1400 only Spain, Sicily and Crete re-emerged as Christian territories.

In this study, we present lipid biomarker and palynological data for a sediment core from Lake Dojran (Macedonia/Greece), which covers the entire Holocene period. We analyzed vascular plant-derived n-alkanes, combustion-derived polycyclic aromatic hydrocarbons (PAHs), fecal steroids, and bacterial and archaeal glycerol dialkyl glycerol tetraether (GDGT) lipids in concert with microcharcoal and pollen assemblages to reconstruct climatic, environmental, and human impact in the Dojran catchment and the greater Dojran area. Overall, our results suggest a relationship between anthropogenic activity and environmental/climatic change since increased human impact corresponds to phases of higher humidity and high lake levels at Lake Dojran. During the early Holocene, the record reveals increasing temperatures and humidity and concurrent increasing vegetation cover and runoff/soil erosion, respectively. Following a thermal maximum during the middle early Holocene, temperatures decrease gradually until present. The middle-Holocene at Lake Dojran is characterized by relatively stable environmental conditions followed by greater climatic instability and strong anthropogenic overprint during the late-Holocene. The fecal stanol record reveals phases of increased human impact during the early Bronze Age, the late Bonze/early Iron Age, and the Middle Ages. A phase of low stanol and PAH concentrations from the late Iron Age until the early Middle Ages is either related to ecosystem changes and/or changes in settlement pattern since concurrent pollen data indicate intensified land use. Human impact re-intensified during the Middle Ages with some variability probably related to climatic variations of the ‘Medieval Warm Period’ and the ‘Little Ice Age’.

Purpose. As a result of preparations for the flooding of the Boguchan Hydroelectric Power Station reservoir bed, the Lower Angara region has witnessed increased activity as an archeological source base in recent years. It initiated the development of studies on the taxonomy of pottery traditions, both in the region and in adjacent territories, their chronology and interaction models. A number of informative archaeological sites at the estuary of the Kova River were excavated in large-scale horizontal exposures. Morphological analysis of the most informative part of the collection of surveys of 2008–2011, its comparative studies and the subsequent analysis of the spatial and stratigraphic context of the wares were the object of this paper. Results. A number of pottery groups were identified and their cultural-chronological attribution was proposed. Pottery of the Middle Ages predominate – Ust’-Kova type vessels, wares decorated with thin and smearing cordons, combed decorated pottery. The period of the Early Iron Age is represented by the Tsepan’ culture pottery, vessels with ‘wisp’ cordons and thin cordons decorated with finger pinches. Morphologically heterogeneous ‘pearl-ribbed’ pottery is attributed to the Bronze Age. Among the Neolithic ceramics, ‘net-impressed’ pottery (including the Aplin type), wares of Posol’sk and Ust’-Belaya types, as well as vessels close to Serovo pottery were presented. The complexes of the Early Iron Age – the Middle Ages have little information content due to the fact that the upper culture-bearing sediments are largely disturbed. There is a tendency toward a shift of site zones from the Angara coast in the Neolithic and Bronze Age to the right bank of the Kova River in subsequent periods. Conclusion. The collection includes wares dating from the Neolithic to the ‘Russian’ time. Conclusions about the information content of materials of cultural layers for further research are made. A subsequent collation of observations on settlement location trends will be able to reveal mobility patterns among carriers of various pottery traditions.

This work intends to update the knowledge related to the human occupation of “Castro do Muro” from the Bronze Age to the Middle Ages. This place has a significant tradition in archaeological literature due to the presence of an imposing walled circuit, whose width oscillates between 3.5 to 4 meters and a perimeter of 3.927 meters, within which was built an important settlement that emerged during the Late Bronze Age and extends to the Old Iron Age. There was also a Roman occupation, a probable rock castle and a medieval monastery, as attested by the ceramic, lithic and metallic materials collected in archaeological works and surface findings.
