phytoplankton decline


In todays nature magazine there was an article about the “Global phytoplankton decline over the past century”. I have no access to the article however in an article by Markus Becker – a reporter from the german news magazine Spiegel Online – it was reported that since 1950 on average the mass of phytoplankton declined globally by 40%. Since phytoplankton are amongst others a major food source for food webs this affects e.g. the abundance of fish. Moreover phytoplankton are responsible for much of the oxygen present in the earth’s atmosphere. A main reason for the decline of phytoplankton is climate change.
