Microbiome changes in the sponge Halichondria panicea along the Baltic Sea salinity gradient [PDF]
Frontiers in MicrobiologyThe Baltic Sea is characterized by a strong salinity gradient, which impacts the diversity and composition of free-living macro- and microorganisms. Much less is known about how host-associated microorganisms are affected by decreasing salinities. Marine
