Abstract

fetched live from OpenAlex

Little is known about the movements and home range of boreal woodland caribou (Rangifer tarandus) in the James Bay lowlands. As part of ongoing studies to measure the potential effects of the De Beers Victor Project on the local and regional environment, a study of woodland caribou was initiated. This study involves the use of GPS collars with Argos satellite system uplink to monitor movements of caribou. Additional aerial surveys of a study area (22 000 km2) in the early and late winter are used to provide an overall indication of the usage of the area around Victor by caribou and other wildlife. Animals were collared in December 2004 at varying distances from the Victor site (max. 60 km). Preliminary data for 2005 has been analysed. During 2005, some animals moved large distances >480 km from Victor, while others were relatively sedentary. One animal (from the total of ten) was harvested by a hunter in March. The only obvious trend in movement patterns occurred in the middle of November when all the collared animals began to move north-west. The daily distances moved in November were much greater (10-20 km/d) than earlier in the year (0.5-10 km/d) and by mid December they were all north and west of their locations when first collared, in some cases more than 480 km to the northwest of their initial capture sites. The minimum annual distances covered for the nine remaining animals ranged between 900 and 1500 km. The home ranges of the caribou ranged from 8000 km2 to 56 380 km2 with a mean home range of 23 434 km2, which is much greater than boreal woodland caribou in other parts of Ontario.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
