Tracking the Dispersal of the Endangered Eastern Prickly Pear Cactus (Opuntia cespitosa) by Animal Vectors in Canada
Bibliographic record
Abstract
Opuntia cespitosa is an endangered cactus with only one substantive population in Point Pelee National Park (PPNP), Canada. Staff observations at the Park include that many cactus fingerlings (young Opuntia seedlings) appeared in sites frequented by the Eastern Wild Turkeys. This study aims to assess the effectiveness of seed dispersal by wild turkeys and other animals at PPNP, and to identify the primary seed dispersers. We used trail cameras, analyzed wild turkey scats, and examined fingerlings to determine potential seed dispersers from August to October 2020. Migrating birds were the most frequent visitors at cactus sites, followed by rabbits and wild turkeys. We conclude that while wild turkeys consume and disperse cactus seeds, the seeds are not necessarily preferred by them in their diet. This research has important implications for O. cespitosa’s reproduction and potential genetic variability and can be used to inform Park managers about conservation strategies for this species.

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.
