Ecology of a Recently Discovered Population Segment of Blanding’s Turtles, <em>Emydoidea blandingii</em>, in Barren Meadow and Keddy Brooks, Nova Scotia
Bibliographic record
Abstract
Blanding’s Turtles in Barren Meadow Brook and Keddy Brook are part of the Pleasant River population, the easternmost population currently recognized in Nova Scotia. Previous genetic analysis demonstrated restricted gene flow among the populations of Nova Scotia. The conservation of this genetic diversity is important to reduce genetic drift and bottleneck effects in these populations. Between 2006 and 2008, the population in Barren Meadow Brook and Keddy Brook was estimated using visual surveys, trapping, and radio-tracking. Over the three years, surveys yielded 69 individuals (14 females, 22 males, 29 juveniles, 4 undetermined). Capture-mark-recapture analysis using the Chapman variation of Petersen formulas for bi-census yielded population estimates of 88 Blanding’s Turtles. The sex ratio did not deviate significantly from 1:1. Applying minimum convex polygon (MCP) and kernel methods to radio-tracking data yielded preliminary estimates of home range size and location for males and females. Females had larger homes ranges, probably because of the limited availability of nesting sites in Barren Meadow and Keddy Brooks. New overwintering sites and three new nesting sites were identified. Home ranges of males did not overlap, and males seemed to show territorial behaviour. An expanded sample, particularly of males, is needed to improve the assessment of home ranges, movements, and behaviour. To date, conservation efforts in this population have focused on females. If home ranges of males in an expanded sample also do not overlap, then conservation of this population requires closer scrutiny of males and their population genetic structure.

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.
