Endophyte presence as a potential stressor on growth and survival in Antarctic macroalgal hosts
Filamentous algal endophytes are common in many species of macroalgae along the Antarctic Peninsula, but their influence on host physiology is unknown. However, worldwide endophyte–macroalgae symbioses are known to be detrimental to vital functions of a host. The growth and survival of four Antarcti...
