Environmental influences on Vibrio populations in northern temperate and boreal coastal waters (Baltic and Skagerrak Seas).

ABSTRACT: Even if many Vibrio spp. are endemic to coastal waters, their distribution in northern temperate and boreal waters is poorly studied. To identify environmental factors regulating Vibrio populations in a salinity gradient along the Swedish coastline, we combined Vibrio-specific quantitative competitive PCR with denaturant gradient gel electrophoresis-based genotyping. The total Vibrio abundance ranged from 4 x 10(3) to 9.6 x 10(4) cells liter(-1), with the highest abundances in the more saline waters of the Skagerrak Sea. Several Vibrio populations were present throughout the salinity gradient, with abundances of single populations ranging from 5 x 10(2) to 7 x 10(4) cells liter(-1). Clear differences were observed along the salinity gradient, where three populations dominated the more sali
