persistent differences between coastal and offshore kelp forest communities in a warming gulf of maine.kelp forests provide important ecosystem services, yet coastal kelp communities are increasingly altered by anthropogenic impacts. kelp forests in remote, offshore locations may provide an informative contrast due to reduced impacts from local stressors. we tested the hypothesis that shallow kelp assemblages (12-15 m depth) and associated fish and benthic communities in the coastal southwest gulf of maine (gom) differed significantly from sites on cashes ledge, 145 km offshore by sampling five c ...201829298307
highly localized divergence within supergenes in atlantic cod (gadus morhua) within the gulf of maine.atlantic cod (gadus morhua), is known to vary genetically across the north atlantic, greenland, and newfoundland. this genetic variation occurs both spatially and temporally through decades of heavy fishing, and is concentrated in three linkage disequilibrium blocks, previously defined by pedigreed linkage mapping analysis. variation within these genomic regions is correlated with both seawater temperature and behavioral ecotype. the full extent and nature of these linkage groups is important in ...201728359300
slow adaptation in the face of rapid warming leads to collapse of the gulf of maine cod fishery.several studies have documented fish populations changing in response to long-term warming. over the past decade, sea surface temperatures in the gulf of maine increased faster than 99% of the global ocean. the warming, which was related to a northward shift in the gulf stream and to changes in the atlantic multidecadal oscillation and pacific decadal oscillation, led to reduced recruitment and increased mortality in the region's atlantic cod (gadus morhua) stock. failure to recognize the impact ...201526516197
