Temperature-dependent survival and growth of early juvenile Bering Sea snow crab ( Chionoecetes opilio ) and Tanner crab ( Chionoecetes bairdi ): implications for optimal crab thermal habitat in a rapidly warming Alaska Arctic. Building a climate change and ocean acidification stress indicator for Bering Sea red king crab fisheries management Drivers of bitter crab syndrome in eastern Bering Sea snow and Tanner crab Size and density-dependent incidence of BCD suggests cod predation more important than fishery for disease control Shifting fish distributions drive changes in predation in the eastern Bering Sea A comparison of species distribution model structures for describing juvenile salmon distribution and abundance in the eastern and northern Bering Sea
