Using the most comprehensive conservation data available for both marine and non-marine organisms, research led by Dr Thomas Webb, from the University's Department of Animal and Plant Sciences, has shown that 20 to 25 per cent of the well - known species living in our seas are now threatened with extinction — the same figure as land living plants and animals.
«Biological oceanographers have speculated that early life stages of marine organisms might be particularly sensitive to ocean acidification, but the underlying mechanisms remain unknown for most species,» says David Garrison, program director in NSF's Division of Ocean Sciences, which funded the research through an ocean acidification competition.
