The Circumpolar North is generally recognized as a challenging environment to inhabit and yet, we know relatively little about how people managed their welfare in these places. Here, we add to the understanding of maritime hunter-gatherers in the subarctic North Pacific through a comparative approach that synthesizes biogeographic and archaeological data from the Kuril Islands. We conclude that our faunal, ceramic and lithic evidence support biogeographical expectations as assemblages from low biodiversity and insular regions show limited diet breadth, more locally produced pottery and a conservation of lithic resources. However, we highlight that these ecological factors did not strictly determine the occupation history of the archipelago as radiocarbon data suggests all regions experienced similar demographic fluctuations regardless of their biogeography. These results imply additional pressures influenced the strategic use and settlement of the Kuril Islands and the need for increased chronological resolution to disentangle these complex historical factors.
IntroductionMaritime hunter-gatherers can be broadly defined as those groups whose subsistence relies primarily on wild resources extracted from the sea. However, given that many northern regions have had only intermittent human presence (Hoffecker 2005; Friesen and Mason 2016) and have been less intensively studied, the archaeological record of Arctic and sub-Arctic maritime hunter-gatherers is often scant. This is unfortunate as the archaeology of northern foragers present valuable opportunities to study long-term interactions between humans and their environments. This is especially true given the challenging climates, inherent instability of highlatitude ecosystems and their reliance on local resources for survival (Damm et al. 2019). Here, our approach is to compare archaeological and radiocarbon evidence from maritime hunter-gatherers that inhabited a subarctic landscape: the Kuril Islands, an archipelago that stretches from the northernmost Japanese island of Hokkaido to the southern tip of the Kamchatka peninsula (see Fig 1). We start from the well-established premise that islands make good areas for studying historical hunter-gatherer relationships to ecological variability (Keegan
