The pH of the world's oceans has decreased since Industrial Revolution due to oceanic uptake increased atmospheric CO2 in a process called ocean acidification. Low been linked negative impacts on calcification, growth, and survival calcifying invertebrates. Along Western Antarctic Peninsula, dominant brown macroalgae often shelter large numbers diverse invertebrate mesograzers, many which are calcified. Mesograzer assemblages this region composed amphipods have key roles macroalgal communities. Understanding acidification is vital for understanding how these communities will be impacted by climate change. To assess long-term may influence different members assemblages, particularly amphipods, associated with alga Desmarestia menziesii were collected from immediate vicinity Palmer Station, Antarctica (S64°46', W64°03') January 2020 maintained under three treatments simulating ambient conditions (approximately 8.1), near-future 2100 (pH 7.7), distant future 7.3) 52 days then enumerated. Total assemblage number relative proportion each species found similar across treatments. These results suggest that amphipod D. resistant exposure pH.
