Stable carbon and nitrogen isotope analyses of bone collagen, and stable carbon and oxygen isotope analyses of the bone's structural carbonate, were performed on 120 individuals representing 33 vertebrate species, including a single human bone find, collected from the Late Neolithic settlement at Pestenacker, Bavaria, Germany. We were thus capable of reconstructing a rather complex food web and could also address particular issues, such as whether humans influenced the diet of their domestic animals as opposed to their wild relatives, or whether humans perhaps had to compete over food with their domesticates. A rather unexpected result was that freshwater fish, which could be captured in the nearby river Lech, a major tributary of the Danube, contributed to the human diet only occasionally. As for mammals, it was also possible to recognise different trophic levels for birds and aquatic vertebrates, applying stable isotope analyses to both bone collagen and structural carbonate. In the case of fish, δ18O values at least revealed a physiological regularity in terms of temperature preference, besides diet. Conceivably, variability of δ18O in surface water as reflected, for example, by species that avoided human settlements, may help to characterise past ecosystems and to define site catchment exploited by Neolithic man in the course of food acquisition.

ABSTRACT. Aboriginal and non-Aboriginal notions of geography, nature and space sometimes compete, and these differences can create barriers to joint environmental problem-solving. This paper examines the Ardoch Algonquin First Nation and Allies (AAFNA) and the strategies they used in juridical and legislative settings to make their voices heard. In the Tay River Ontario Environmental Review Tribunal (2000–2002), AAFNA attempted to introduced their knowledge of the environmental deterioration which would be caused by a Permit To Take Water issued to a multinational corporation by the Ontario Ministry of Environment. The paper is divided into two parts: first, it describes the concepts of Algonquin knowledge, jurisdiction and responsibility; second, it explores the strategies used to integrate their perspective into legal proceedings constructed by the Canadian government. This case reveals how some Algonquin people conceive of space and responsibility in deeply ecological, rather than narrowly juridical, terms. It establishes that their broad concepts of knowledge, land and jurisdiction are incompatible with existing Euro-Canadian divisions of legal responsibility and ecological knowledge, but at the same time can serve as the means by which they challenge the current structure of Aboriginal and Canadian relations. 相似文献
