Comparitive growth and movement analysis of headstarted Blanding's turtles (Emydoidea blandingii) at Kejimkujik National Park and National Historic Site of Canada
Bibliographic record
Abstract
With an estimated population of 350 adults, the population of Blanding's turtles in Nova Scotia is listed as Endangered both federally and provincially. Headstarting is used in Nova Scotia as part of the recovery program and is designed to improve the survivorship of turtles at an early life history stage. In 2009 and 2010, the largest Blanding's turtle headstarting effort to date in Nova Scotia was undertaken with eggs collected from Kejimkujik National Park and National Historic Site (KNP). These eggs were incubated and hatched at Oaklawn Zoo, Aylesford, Nova Scotia, and the hatchlings were subsequently raised in captivity for two years. A total of 154 headstarted turtles were re-introduced into KNP during the summers of 2011 and 2012. A total of 29 headstarted turtles released at Atkins Brook were tracked using radio telemetry to study growth and movement. For comparative purposes, 7 wild incubated turtles were also collected and tagged for radio tracking. Turtles were tracked weekly from April to November 2012 to collect movement data and were measured the first week of every month. For the purpose of analysis, turtles were divided into 4 groups: 2009-headstarts, 2010-headstarts, wild (3yrs), and wild (5-7). A pairwise comparison found a difference in movement rates between groups. Wild (5-7) turtles were found to have higher movement rates than all other groups (P < 0.1 for all cases). Headstarted and wild (3yrs) had similar movement rates. An ANCOVA test found no significant difference (F = 0.534, df = 3, P = 0.660) in growth rates of headstarted and wild turtles. These results suggest that headstarted turtles are able to adapt to the wild successfully, but further study on the long-term survival of headstarts will be important to determine the overall success of the headstarting program in Nova Scotia.

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.
