Life Threatened in Acidic Coastal Waters

摘要: Increasing atmospheric CO2 is not only increasing global temperature but also rapidly acidifying seawater through formation of carbonic acid (ocean acidification). Emerging evidence from laboratory research indicates that predicted changes in ocean environments could have profound implications for marine ecosystem, however, it relatively unclear how biota will respond to warming and acidification. Furthermore, most published papers used future concentration their experimental protocols, ignoring spatial heterogeneity carbonate chemistry, which manifested coastal regions deep sea. This paper first summarizes empirical on effects organisms, then discusses the importance considering local conditions improve our prediction ability fate organisms acidified oceans. Marine molluscs been shown be highly sensitive elevations ambient CO2, particular during larval shell formation. In addition, data accumulated sublethal impacts morphology, physiology behavior. Early development echinoderms are significantly affected by pCO2, there seems a difference interspecies sensitivity different latitudes high intra-species sensitivity. Gonad can severely impacted CO2. As compared with known echinoderms, some crustaceans, particularly copepods amphipods, fish appear less vulnerable Anthropogenic environment multifaceted complex. Scientific endeavor utmost necessity secure this productive region. Investigations reflecting biotic abiotic needed precisely predict ecosystem shape face changing environment.
