Invasive range expansion by the Humboldt squid, Dosidicus gigas , in the eastern North Pacific
Abstract
A unique 16-year time series of deep video surveys in Monterey Bay reveals that the Humboldt squid, Dosidicus gigas , has substantially expanded its perennial geographic range in the eastern North Pacific by invading the waters off central California. This sustained range expansion coincides with changes in climate-linked oceanographic conditions and a reduction in competing top predators. It is also coincident with a decline in the abundance of Pacific hake, the most important commercial groundfish species off western North America. Recognizing the interactive effects of multiple changes in the environment is an issue of growing concern in ocean conservation and sustainability research.

In pelagic habitats that have been overfished for predatory fish (tuna, sharks), the large Humboldt squid Dosidicus gigas becomes more abundant and appears to adopt the role of the large gnathostomes.
“One observation from Recent ecosystems is that, for example, in pelagic habitats that have been overfished for predatory fish (tuna, sharks), the large Humboldt squid Dosidicus gigas becomes more abundant and appears to adopt the role of the large gnathostomes (Zeidberg & Robinson 2007).”

The Discussion (page unavailable) says tuna and billfish populations have declined, that squid are replacing large fishes, and that predator removal may promote Dosidicus growth and range expansion. It does not establish that overfishing caused the decline or that shark populations were depleted; its proposed link between predator removal and squid growth remains qualified. (LLM, conf=0.84)

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.
