The ability of … Witryna12 cze 2013 · The findings suggest that the effects of ocean acidification may not have as deleterious an impact on sea urchin size or population growth rates as previously thought. Good news for the keystone species, and good news for the creatures that eat them. ... The other species include coral, algae, and the California mussel.
Witryna5 paź 2013 · While there is recognition that ocean acidification may alter net primary production, via the increased solubility of biogenic calcareous structures and reduced survival of calcifying species that consume algae [ 11, 17 ], it may also alter production directly, especially under elevated temperature [ 18 ]. Witryna20 gru 2010 · Collectively our results suggest that ocean acidification could reduce nitrification rates by 3–44% within the next few decades, affecting oceanic nitrous oxide production, reducing supplies of oxidized nitrogen in the upper layers of the ocean, and fundamentally altering nitrogen cycling in the sea.

WitrynaOcean acidification could have an impact on food supplies. Richard says, 'There was concern that the shelled animals we eat, like oysters, may eventually all dissolve and die. 'A lot of experiments have been carried out looking at this issue, and the results have shown that the response to increased acidity varies between species.'
