Moreover, current models of phytoplankton host-virus interactions predict rapid extinction of both host and virus. Nevertheless, marine phytoplankton and their respective viruses do coexist in marine ecosystems. To investigate this apparent paradox we performed a series of experiments which show that phytoplankton populations always recover after virus-induced lysis and that endemic viral infections may promote survival of the host population. We hypothesize that phenotypic plasticity of algal susceptibility to viral infection makes such coexistence of host and virus possible.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
