Shift in polar benthic community structure in a fast retreating glacial area of Marian Cove, West Antarctica
Abstract Glacier retreat is a major long-standing global issue; however, the ecological impacts of such retreats on marine organisms remain unanswered. Here, we examined changes to the polar benthic community structure of “diatoms” under current global warming in a recently retreated glacial area of...

Abstract Glacier retreat is a major long-standing global issue; however, the ecological impacts of such retreats on marine organisms remain unanswered.
