Abstract

fetched live from OpenAlex

The Humboldt squid ( Dosidicus gigas ) has been expanding its geographical range in the eastern North Pacific Ocean over the past 20 years. This species of squid has advanced from the most southern part of their native range, off the Chilean coast, northward to southern Alaska. This expansion of a fast-growing pelagic predator is concerning and should be evaluated. Dosidicus gigas has been known to negatively affect native species of fish populations, such as Pacific hake (Merluccius productus), when expanding its range. The effects of an establishment of a D. gigas population in Pacific Canadian waters on both ecological systems as well as commercial fisheries should be assessed to develop management plans to protect native species and commercial fisheries. The reduction of potential effects of D. gigas establishment on native species of the eastern North Pacific is essential to conserving current native populations. A complete list of trophic interactions between  D. gigas and species native to the eastern North Pacific is still underdeveloped. To qualitatively assess what is driving the migratory behaviour of D. gigas , the physiological, reproductive, and ecological traits of the species are reviewed here. The results indicate that warming water temperatures, reproductive plasticity, and prey/predator interactions are the leading causes thought to be driving D. gigas  northward.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
