Invasive alga reaches California
Open accessAbstract
The recent discovery of the marine green alga Caulerpa taxifolia on the Californian coast has raised public concern about the potential danger of a new invasion similar to the one endured by the Mediterranean Sea over the past decade. A small colony of C. taxifolia introduced into the Mediterranean in 1984 from a public aquarium has spread to more than 6,000 hectares today, outcompeting native species and seriously reducing diversity in areas of the northwestern Mediterranean. This invasive strain of C. taxifolia differs from tropical populations in that it is much larger, grows more vigorously, does not rely on sexual reproduction, and is resistant to low temperatures. Here we evaluate the risk of invasion by Californian C. taxifolia by comparing it genetically with the Mediterranean and aquarium strain, as well as with native tropical populations. Our results show that the Californian alga is the same as the invasive Mediterranean strain, calling for its rapid eradication to prevent a new invasion.

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.
