Scientific Reports 5: Article number: 10349; published online: 20 May 2015; updated: 31 July 2015

In the original version of this Article, the Abstract contains a typographical error.

“Additional experimentation illustrated how these effects amplified over time, resulting in greater primary producer biomass sediment chlorophyll a content (Chla) in the longer term”.

should read:

“Additional experimentation illustrated how these effects amplified over time, resulting in greater primary producer biomass (sediment chlorophyll a content) in the longer term”.

This has now been corrected in both the PDF and HTML versions of the Article.
