Hoe stabiel is de toekomstboom?

Op 18 januari 2007 raasde een storm over West-Europa die tientallen dodelijke menselijke slachtoffers maakte en enorme materiële schade aanrichtte. De storm ontwortelde een miljoen bomen. Hadden we schade kunnen voorkomen of is dit het soort natuurgeweld waartegen geen kruid gewassen is? Hoofdlijnen uit Alterra rapport over "Storm, bos, beheer en stabiliteit

"In this chambered tumulus were found cleft skulls ...": an assessment of the evidence for cranial trauma in the British Neolithic

Interpersonal violence is a powerful expression of human social interaction. Yet a consideration of violence in the past has done relatively little to inform our discussions of the British Neolithic. Here, we present the results of an examination of some 350 earlier Neolithic crania from mainly southern Britain. Of these, 31 show healed or unhealed injuries suggestive of interpersonal violence. We suggest a conservative estimate of 2% fatal cranial injuries, and 4 or 5% healed injuries. These data are used as a platform to discuss possible contexts for, and consequences of, violence. We argue that, regardless of its actual prevalance, the reality or the threat of interpersonal violence can have an important affect on both the behaviour of individuals and the structure of society

Food Production, Processing and Foodways in Neolithic Ireland

When compared with earlier periods, the Neolithic in Ireland (4000–2500 cal BC) witnessed enormous changes in the foods being produced, and the work involved in their production and processing. Several crops were introduced–archaeobotanical studies indicate that emmer wheat became the dominant crop, with evidence also for barley (hulled and naked) and flax. Gathered resources were not abandoned; on the contrary, there is substantial evidence for a variety of nuts, fruits and leafy greens. Zooarchaeological studies indicate that new animals also arrived, including domesticated cattle, pig and sheep. Recent studies have provided substantial information on the timing and nature of these new ways of farming and living, but the focus is often on ingredients rather than food products. There are many challenges in determining which foods were being made with these new crops and animals, and in assessing their dietary and social importance. While cereals have been found at many sites, for example, it is not clear if they are being ground, boiled or other techniques are used for their processing. In this paper we explore aspects of food production, processing and foodways in Neolithic Ireland, drawing upon evidence from archaeobotany, zooarchaeology, isotopes, human skeletal remains and artefacts

Further isotopic evidence for seaweed-eating sheep from Neolithic Orkney

The antiquity of the practice of grazing on and/or foddering with seaweed is of interest in terms of understanding animal management practices in northwest Europe, where provision had to be made for overwintering. Orkney holds a special place in this discussion, since the sheep of North Ronaldsay have been confined to the seashores since the early nineteenth century, and are entirely adapted to a diet consisting mainly of seaweeds. Here, we report the results of stable carbon and nitrogen isotope analysis of twenty-five faunal specimens from the Neolithic chambered tomb of Quanterness, Orkney. Three of the 12 sheep analysed show elevated δ13C values that can only be explained by the consumption of seaweed. Radiocarbon dates place two of the three animals in the Neolithic, coeval with the use of the monument for burial, while the third animal dates to the Chalcolithic/Early Bronze Age. The findings are placed into the wider context of previous isotopic analyses of domestic fauna from prehistoric Orkney. A disjoint is noted between the results for bone collagen – where seaweed consumption seems to relate to the pre-natal period, since all the animals with high δ13C values are less than ca. three months of age – and previous studies using high-resolution sequential enamel measurements, which suggest a repeated pattern of winter consumption of seaweed in older animals

Radiocarbon dating of a multi-phase passage tomb on Baltinglass Hill, Co. Wicklow.

Baltinglass is a multi-chamber Neolithic passage tomb in Co. Wicklow, Ireland, excavated in the 1930s. This paper presents the results of a radiocarbon dating programme on charred wheat grains and hazelnut shell found underlying the cairn, and on cremated human bone found within and near two of the monument’s five chambers. The results are surprising, in that three of the six determinations on calcined bone pre-date by one or two centuries the charred cereals and hazelnut shells sealed under the cairn, dating to c. 3600–3400 calbc. Of the remaining three bone results, one is coeval with the charred plant remains, while the final two can be placed in the period 3300/3200–2900 calbc, that is more traditionally associated with developed passage tombs. A suggested sequence of construction is presented beginning with a simple tomb lacking a cairn, followed by a burning event – perhaps a ritual preparation of the ground – involving the deposition of cereal grains and other materials, very rapidly and intentionally sealed under a layer of clay, in turn followed by at least two phases involving the construction of more substantial chambers and associated cairns. What was already a complex funerary monument has proven to be even more complex, with a history spanning at least six centuries

Isotope evidence for the use of marine resources in the Eastern Iberian Mesolithic

There are relatively few coastal Mesolithic sites in the Iberian Mediterranean region, probably due to a number of factors including sea level changes and the disappearance of sites due to agriculture and urbanisation. However, recent excavations have uncovered inland sites that have marine faunal remains (i.e. molluscs and fish) and lithics from the coastal area, which both indicate interactions between the coast and the upland valleys. These inland sites are located at a distance of 30e50 km from today¿s coastline and are at altitudes higher than 1000 m. We report on additional information on the links between the coast and these inland sites through the use of dietary isotope analysis (carbon and nitrogen stable isotope analysis) of collagen extracted from human and faunal remains at the sites of Coves de Santa Maira, Penya del Comptador and Cingle del Mas Nou. The results indicate that Mesolithic diet in this region was largely based on C3 terrestrial resources, but there was measurable evidence of low-level consumption of marine resources at both coastal and inland sites
