We investigated the relative roles of natural factors and shoreline harvest leading to recent declines of the black leather chiton (Katharina tunicata) on the outer Kenai Peninsula, Alaska (U.S.A.). This intertidal mollusk is a strongly interacting grazer and a culturally important subsistence fishery for Sugpiaq (Chugach Alutiiq) natives. We took multiple approaches to determine causes of decl...

Gray whales are coastal migratory baleen whales that are benthic feeders. Most of their feeding takes place in the northern Pacific Ocean with opportunistic feeding taking place during their migrations and residence on the breeding grounds. The concentrations of organochlorines and trace elements were determined in tissues and stomach contents of juvenile gray whales that were taken on their Ar...

The ancient lowland Maya have been traditionally portrayed as swidden (shifting cultivation) agriculturalists (1). The persistence of the swidden concept has inhibited field inquiry of past modes of lowland subsistence, often preserving what may be an unfounded bias concerning the cultivation techniques employed by the Maya. Moreover, the absence of adequate subsistence research has, in effect,...

We have argued elsewhere [Cannon, M.D., Meltzer, D.J., 2004. Early Paleoindian foraging: examining the faunal evidence for large mammal specialization and regional variability in prey choice. Quaternary Science Reviews 23, 1955–1987] that the North American archaeofaunal record provides little support for the notion that Early Paleoindians across the continent practiced a uniform subsistence st...

Reduced sea ice has made the Arctic Ocean more accessible for vessel traffic. In turn, the heightened interest to better understand rapidly changing sea ice dynamics, ecosystems, and related ocean processes in the Arctic Ocean has led to closer interactions with and the need to avoid potential conflicts between scientific researchers and Indigenous coastal communities. In particular, researcher...

Abstract Energy costs are large and increasing in rural Alaska communities, so communities turning to renewable energy. While, many of these have a mixed subsistence-cash economy, the relationship between energy subsistence has not been studied. Tanana, biomass program we conducted interviews with 61 households 2017 understand how residents perceive its association activities. We analyzed Depar...
