Microbial plankton communities in the coastal southeastern Black Sea: biomass, composition and trophic interactions
Aytan, Ülgen; Feyzioğlu, Ali Muzaffer; Valente, Andre; Ağirbaş, Ertuğrul; Fileman, Elaine S. (Polish Acad Sciences Inst Oceanology, 2018)We investigated biomass and composition of the pico-, nano-and microplankton communities in a coastal station of the southeastern Black Sea during 2011. We also examined trophic interactions within these communities from ... -
