The Biogeography of Ground Beetles (Coleoptera: Carabidae) on the Islands of Lac la Ronge, Saskatchewan, Canada
Bibliographic record
Abstract
Islands offer unusual opportunities for studying theoretical concepts in ecology. I studied the role of island size and isolation in structuring assemblages of ground beetles (Coleoptera: Carabidae) on the islands and adjacent mainland of Lac la Ronge, Saskatchewan, Canada. Carabid beetles were collected on 30 islands (0.2 – 980.7 ha in size, 0.13 – 10.7 km from mainland) and five mainland sites using pitfall traps throughout the frost-free season. Carabid body size, wing length and seasonal activity information was obtained from the literature. In wing-dimorphic species, wing length was diagnosed by removing the elytra and subsequent dissections to determine the condition of flight muscles. Island size was an important factor affecting beetle assemblage, diversity, and population processes on islands. Island isolation did not negatively influence diversity at the scales examined in this study. Life history characteristics of species such as body size, wing length, and breeding period significantly influenced the distribution of beetles on islands. This work suggests that small islands experience greater turnover of carabids, particularly large-bodied flightless species, and that this may account for the island area effect observed in this island system.

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.
