How are urchins affected by acidification
WebOne of the key marine groups most likely to be impacted by acidification are the echinoderms. Researchers investigate the possible impacts of climate change by exposing larvae and adults to water that simulates warmer and more acidic seawater. Based on those experiments, researchers predict that echinoderm larvae exposed to those conditions ... Web23 de fev. de 2015 · The reason: ocean acidification.
