Moose Hunters of the Boreal Forest? A Re-examination of Subsistence Patterns in the Western Subarctic

Many descriptions of lifestyles in the western subarctic region have been built on the premise that the hunting and use of moose was a central feature of those lifestyles. While this may be true, it is worthwhile to question the time depth that underlies this adaptation and the degree to which it may have applied to former societies inhabiting the boreal forest region. Any such effort must include an analysis of available faunal remains from archaeological sites in that region. A consideration of the faunal record suggests that the intensive utilization of moose is relatively new in the western boreal forest, or at least was not widely characteristic of the late Holocene period. Thus, it cannot be assumed that the archaeologically designated late prehistoric "Athapaskan tradition" was isomorphic with modern subsistence regimes. To the degree to which large game played a central role in Athapaskan lifestyles, it was caribou, rather than moose, that seems to have dominated in the northern ecotonal region. Fish and small game seem to have dominated in importance in the southern coastal forest region, with a mixed subsistence economy characteristic of the central region. Historical factors, primarily involving widespread fires, habitat disturbance and impacts on predators, seem to be most responsible for the increase in moose numbers during the past century. The role of fire is particularly critical and may have had great influence on the nature and stability of past subsistence regimes in the boreal forest region, including impacts on both large and small game.Key words: moose, western Subarctic, boreal forest adaptations, faunal analysis, fire ecology, late Holocene period, optimal foraging theory, Athapaskan traditionMots clés: orignal, Subarctique occidental, adaptations de la forêt boréale, analysdee la faune, écologie des feux, holocène supérieur, théorie du fourrage maximal, tradition athapaskienn

Stable Isotope Chemistry, Population Histories and Late Prehistoric Subsistence Change in the Aleutian Islands

Aleut population history has been a topic of debate since the earliest archaeological investigations in the region. In this paper, we use stable isotope chemistry to evaluate the hypothesis that two distinct groups of people, Paleo- and Neo-Aleut, occupied the eastern Aleutians after 1000 BP. This study focuses on 80 sets of directly dated eastern Aleutian burial assemblages from Chaluka midden, Shiprock Island and Kagamil Island. We use a linear mixing model informed by isotopic analysis of two large Aleut faunal assemblages to address temporal and spatial variation in human carbon and nitrogen stable isotope data from these sites. The patterning we report addresses both Aleut demographic and economic prehistory, illustrating a transition in both at ca. 1000 BP. Our results suggests that the Chaluka diet, dominated by Paleo-Aleut inhumations, differed in both trophic level and foraging location from the other two sites for much of the past 4000 years. Trends in our data also suggest that individuals from Shiprock and Kagamil burial caves, primarily Neo-Aleuts, had enough access to higher trophic level foods to differentiate their bone chemistries from those buried in Chaluka midden. These trends in diet, recently reported genetic differences, as well as the introduction of novel mortuary practices at ca. 1000 BP, suggest that Neo-Aleuts do represent a population new to the eastern Aleutians
