Mortality, pigment cell response and ion regulatory capacity in sea urchin larvae in response to Vibrio infection under pharmacological and ocean acidification treatments ...
Larval stages of the abulacraria superphylum including echinoderms and hemichordates have highly alkaline midguts. To date the reason for the evolution of such extreme pH conditions in the gut of these organisms remains unknown. Here, we test the hypothesis that analogous to the acidic stomachs of v...
