This acceleration appears to follow the release of available organic carbon from one or more copper-sensitive components of the original ecosystem. Ultimately, the bacterial survivors, which demonstrate an increased tolerance to copper with time, reciprocate by providing a source of plant nutrients suitable for the establishment of succeeding phytoplankton regimes.", }
