Relationship between bacterioplankton richness, respiration, and production in the Southern North Sea.

abstract：UNLABELLED:The McMurdo Dry Valleys (MCM) of southern Victoria Land, Antarctica, harbor numerous ice-covered bodies of water that provide year-round liquid water oases for isolated food webs dominated by the microbial loop. Single-cell microbial eukaryotes (protists) occupy major trophic positions within this truncated ...
