The impacts of past, present and future ocean chemistry on predatory planktonic snails

چکیده
The atlantid heteropods represent the only predatory, aragonite shelled zooplankton. Atlantid shell production is likely to be sensitive ocean acidification (OA), and yet we know little about their mechanisms of calcification, or response changing chemistry. Here, present first study into calcification gene expression effects short-term OA exposure on juvenile atlantids across three pH scenarios: mid-1960s, ambient 2050 conditions. Calcification indicate a distinct each treatment. Shell extension volume were reduced from mid-1960s conditions, suggesting that already limited in today's South Atlantic. However, increased Genes involved protein synthesis consistently upregulated, whereas genes organismal development downregulated with decreasing pH. Biomineralization upregulated any deviation carbonate chemistry causes stress, resulting rapid growth. We conclude negatively affected by future OA. also found plentiful food thickness, so synergistic factors are impact resilience an acidifying ocean.
