In the light of discussions surrounding the social changes attributed to the arrival of the Corded Ware culture in central Europe, here we investigate the economic strategies of one of the cultural complexes of the immediately preceding Late Neolithic. The Cham culture of southern Bavaria is characterised by a variety of economic choices but problems remain in synthesising and combining archaeozoological and archaeobotanical evidence. Using lipid residue analysis from Cham culture pottery excavated at the unenclosed settlement of Riedling, Lower Bavaria, we succeed in identifying a dairying economy at this time. Compound-specific lipid radiocarbon dates are then combined with other samples to provide a formal estimate for the duration of activity at Riedling and the first Bayesian chronological model for the Cham culture as a whole. Although data are currently not fine-grained enough to distinguish between competing models for site permanence, we suggest that the Cham culture pattern fits into a wider central European trend of greater mobility and economic flexibility in the pre-Corded Ware horizon, concluding that key economic strategies previously associated with ‘steppe invasions’ were already present in the preceding centuries. Finally, the demonstrated use of cups for milk-based products, as opposed to alcoholic drinks as previously suggested, leads us to propose possible alternative uses and users for these items.

The Neolithic in north-east Asia is defined by the presence of ceramic containers, rather than agriculture, among hunter-gatherer communities. The role of pottery in such groups has, however, hitherto been unclear. This article presents the results of organic residue analysis of Neolithic pottery from Sakhalin Island in the Russian Far East. Results indicate that early pottery on Sakhalin was used for the processing of aquatic species, and that its adoption formed part of a wider Neolithic transition involving the reorientation of local lifeways towards the exploitation of marine resources.

The rates of degradation of metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5(4H)-one] were determined in an untreated Portneuf silt loam, in soil with added organic amendments, and in soil previously treated with metribuzin. While first-order rate kinetics generally described the degradation of the metribuzin in the soil, a quadratic expression was superior. Organic amendments were found to inhibit or accelerate the rate of breakdown of metribuzin depending upon the kind of amendment. Neither a lag phase nor an enrichment was observed from prior treatment with metribuzin.

The analysis of organic residues from pottery sherds using Gas-Chromatography with mass-spectroscopy (GC-MS) has revealed information about the variety of foods eaten and domestic routine at Silchester between the second and fourth–sixth centuries A.D. Two results are discussed in detail: those of a second-century Gauloise-type amphora and a fourth-century SE Dorset black-burnished ware (BB1) cooking pot, which reveal the use of pine pitch on the inner surface of the amphora and the use of animal fats (ruminant adipose fats) and leafy vegetables in cooking at the Roman town of Silchester, Hants.

Techniques for identifying organic residues in pottery have been refined over the years by Professor Evershed and his colleagues. Here they address the problem of radiocarbon dating these residues by accelerator mass spectrometry (AMS) which in turn dates the use of the pot. Fatty acids from carcass and dairy products cooked in the pot were isolated from early Neolithic carinated bowls found at the Sweet Track, Somerset Levels, England, and then dated by AMS. The results were very consistent and gave an excellent match to the dendrochronological date of the trackway. The method has wide potential for the precise dating of pottery use on sites.
