Paleoecological perspectives on landscape history and anthropogenic impacts at Uivak Point, Labrador, since AD 1400
Bibliographic record
Abstract
Archaeological and paleoecological investigations were undertaken at Uivak Point (HjCl-09 located in Okak Bay, Labrador), a site that consists of a winter village comprising the ruins of nine sod houses and a number of tent ring, cache, and other structures. The site was occupied during the late 18th to early 19th centuries, although the immediate area has been used by many cultural groups spanning from Labrador’s early prehistory into the 20th century. Between ca. 3030 and ca. 710 cal. yr BP, cold and dry climate conditions corresponding to the late Neoglacial period generated the abundance of shrub tundra. From ca. 710 to ca. 550 cal. yr BP, conditions became warmer and wetter, triggering the expansion of trees. Since ca. 550 cal. yr BP, there has been an abundance of dry taxa which may reflect the colder conditions of the ‘Little Ice Age’. Subsequent climate warming has allowed the re-expansion of trees and shrubs over the last 200 years. Moreover, our results indicate that the Thule/Inuit harvested many plant species that grew in the vicinity of Uivak Point for food, raw material, and fuel. For example, many anthropogenic remains (burnt fat, burnt moss leaves, and charcoal) were incorporated into the soil. These activities also triggered the establishment of some weeds and apophytes ( Montia Fontana and Silene). Furthermore, our chronostratigraphical and paleoecological data suggest that the site was occupied on an irregular basis since approximately AD 1400.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
