The late adoption of pottery technology in the North American Arctic between 2,500 and 2,800 years ago coincides with development a specialized maritime economy. technologies present an excellent case study for examining possible correlations hunter-gatherer aquatic resource use. Review timing distribution early Alaska shows that is rare dates at earliest to ago; found small numbers primarily coastal areas. Despite expectations use would be strongly linked marine lipids, biomarkers...
Why, when, and how people developed highly specialized marine economies remains the focus of considerable anthropological research. Study maritime adaptations at high latitudes has potential to contribute this debate because low biodiversity increased resource seasonality made reliance on resources particularly risky. New research Cape Krusenstern site complex, located in northwest Alaska, offers a rare opportunity study evolution across environmentally dynamic mid-to-late Holocene Arctic....
Archaeologists need new methods to survey large areas and overcome environmental archaeological barriers site discovery in heavily forested regions. LiDAR (light detection ranging) technology is one possible solution these challenges as digitally clears away vegetation, facilitating large-scale remote sensing survey. The Calapooia Watershed, located the southern Willamette Valley of Oregon, an ideal area utilize LiDAR. While valley lowlands are cleared for agriculture, riverine remain wooded...
Abstract Arctic climate change poses serious threats to polar bears ( Ursus maritimus ) as reduced sea ice makes seal prey inaccessible and marine ecosystems undergo bottom‐up reorganization. Polar bears’ elongated skulls molar dentition, compared their sister species the grizzly bear arctos ), are adaptations associated with hunting seals on a soft, lipid‐rich diet of blubber meat. With significant declines in ice, it is unclear if how may be altering diets. Clarifying dietary responses...
ABSTRACT We explore marine reservoir effects (MREs) in seal bones from the northern Bering and Chukchi Seas regions. Ringed bearded seals have served as dietary staples human populations along coasts of Arctic northeast Asia North America for several millennia. Radiocarbon ( 14 C) dates on terrestrial materials (caribou, plants seeds, wood, wood charcoal) were compared archaeological sites Strait region northwestern Alaska to assess MREs these sea mammals over time. also results C modern...
Le cap Espenberg est une flèche littorale au large de la mer des Tchouktches dans le nord-ouest l'Alaska contenant les vestiges 4000 ans d'occupations humaines et changements climatiques. Les recherches archéologiques paléo-environnementales, menées depuis 2009 cadre d'un projet pluridisciplinaire, apportent informations nouvelles sur chronologie occupations du dernier millénaire documentent l'émergence culture thuléenne directement antérieure ancestrale aux Inuit/Inupiat d'aujourd'hui, un...
Ceramic compositional analysis can contribute to the study of late Holocene Arctic hunter-gatherer social interaction through reconstruction past ceramic distribution patterns. The results an ethnographically informed clay source survey in Northwest Alaska are presented here. provided contextual data on depositional environments, variability, and local environmental factors that influenced pre-contact availability. Geochemical clays tempers clarified location production zones. Concurrence...
Cultural interaction and exchange across the Bering Strait of northern Alaska played a central role in emergence Arctic maritime adaptations. Yet poor chronological control limits our ability to explore processes cultural change over last 5000 years. We address this problem by synthesizing available radiocarbon record for region, carrying out Bayesian analysis regional database, analyzing BAR-1 (Birnirk) site using new dates published paper. Our synthesis illustrative highlights several...
Background COVID-19 has resulted in over 1 million deaths the U.S. as of June 2022, with continued surges after vaccine availability. Information on related attitudes and behaviors are needed to inform public health strategies. We aimed estimate prevalence COVID-19, risk factors infection, a racially, ethnically, socioeconomically diverse urban population. Methods The DFW Prevalence Study Protocol was conducted from July 2020 March 2021 randomly selected sample adults aged 18–89 years,...
