One of the largest isotopic datasets of the ancient Eastern Mediterranean region is evaluated, based on plants (n = 410), animals (n = 210) and humans (n = 16) from Tell Tweini (Syria). Diachronic analysis of plant and faunal specimens from four main periods of occupation: Early Bronze Age (2600–2000 BC), Middle Bronze Age (2000–1600 BC), Late Bronze Age (1600–1200 BC) and Iron Age (1200–333 BC) were investigated. Mean Δ13C results from seven plant species reveal emmer and free threshing wheat, olives, bitter vetch, rye grass and barley were adequately or well-watered during all periods of occupation. The grape Δ13C results suggest excellent growing conditions and particular care for its cultivation. The δ15N results indicate that especially the emmer and free threshing wheats received some manure inputs throughout the occupation sequence, while these were likely further increased during the Iron Age, encompassing also the olive groves and grape vineyards. Generally, domestic animals (cattle, sheep, goats) had C3 terrestrial diets and were kept together in similar environments. However, some animals consumed significant amounts of marine or C4 plants, possibly from disturbed habitats due to land use pressure or salt tolerant grasses and shrubs from wetland environments, which were recorded in the direct vicinity of the site. Middle Bronze Age humans consumed a C3 terrestrial diet with no measurable input from C4, freshwater or marine protein sources. Interestingly, the human diet was relatively low in animal protein and appears comparable to what is considered today a typical Mediterranean diet consisting of bread (wheat/barley), olives, grapes, pulses, dairy products and small amounts of meat. The combined isotopic analysis of plants, animals and humans from Tell Tweini represents unbroken links in the food chain which create unparalleled opportunities to enhance our current understanding of environmental conditions, climate change and lifeways in past populations from the Eastern Mediterranean.

In this paper charcoals from the Syrian sites Tell Mozan and Tell Jerablus are investigated to understand the impact of 4th to 2nd millennium BC settlement on the vegetation. Charcoals from these sites have been identified and oak fragments have been measured for their maximal diameter and annual ring widths. Our results show that while oak had reached its maximal expansion in the Mid-Holocene, and vegetation in the Euphrates Valley was lusher than today, strong anthropogenic impact on the vegetation was occurring, probably already prior to the Late Chalcolithic period. Due to potentially enormous herds of sheep and goat, and possibly large-scale agriculture with perhaps some understory cropping, oak was growing very slowly, to the degree that it must often have had a shrub-like appearance. People did not apply systematic oak woodland management practices, such as coppicing or pollarding. They used dung as an additional fuel, probably to cover for shortages in wood resources. The land appears to have been used both intensively and extensively to a degree that was not sustainable in the long term. This, combined with aridity impact on the oak, probably led to a decrease in oak proportion at Mozan in the Middle Bronze Age. [ABSTRACT FROM AUTHOR]
