The influence of body mass on daily movement patterns and home ranges of the collared lemming (<i>Dicrostonyx groenlandicus</i>)
Bibliographic record
Abstract
While the determinants of animals' space use have been addressed in a large number of studies, its intrasexual variability has received only limited attention. By means of radiotelemetry we found body mass to influence home-range size and distance moved by adult collared lemmings (Dicrostonyx groenlandicus) in northeast Greenland. Male body mass was positively correlated with home-range size. Distance moved by both males and females was also correlated with body mass, but with opposite trends: male movement distances increased with body mass, while female movement distances decreased. This may reflect the fact that larger females occupy the most favourable habitats, i.e., the habitats that minimize the need for movement, and thus exposure to predators, without limiting the food supply. The variability in male home range size and distance moved resulted in variability in the number of females accessible to each male. Larger males had access to more females, and hence, body mass was indirectly important for individual mating opportunities. However, increasing access to females was associated with higher costs in terms of mass loss, probably as a consequence of increased energy requirements and exposure to predators.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
