Mapping human interaction with the Bering Sea ecosystem: Comparing seasonal use areas, lifetime use areas, and “calorie-sheds”

摘要: Abstract Alaska Native coastal communities interact with the marine environment in many ways, especially through harvest of fish, mammals, and seabirds. The spatial characteristics this interaction are often depicted terms subsistence use areas: places where harvests associated travel occur. Another way to consider is examine areas harvested species range during their lifecycle or annual migratory path. In paper, we compare seasonal areas, lifetime “calorie-sheds,” area over which range. Each perspective offers useful information concerning not only nature human–environment interactions but also scope for potential conflict other human activity means by such conflicts could be reduced, avoided, otherwise addressed. Seasonal can used manage short-term activities, as vessel traffic community re-supply. Lifetime indicate required allow hunters fishers flexibility adjust interannual variability perhaps adapt a changing environment. Calorie-sheds about may concerned due impacts on they harvest.
