Metabarcoding the arctic ocean helps reveal its hidden microbial community composition
Öztürk, Rafet Çağrı; Terzi, Yahya; Rodríguez-Machado, Sheila; Başar, Ersan; Feyzioğlu, Ali Muzaffer; Ustaoğlu, Dilek; Ağırbaş, Ertuğrul; Chakrabarty, Prosanta (Central Fisheries Research Institute, 2024)The Arctic Ocean supports a unique and dynamic microbial community, yet its composition, structure, and response to environmental shifts remain incompletely understood. In this study, 16S rRNA gene metabarcoding (targeting ... -
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 ... -
