Status of the North American River Otter in Big Cypress National Preserve
Bibliographic record
Abstract
The North American river otter (Lontra canadensis) is found throughout North America ranging from the coastal areas of Canada, the Atlantic States, the Pacific Northwest, the Gulf of Mexico, as well as the Aleutian Islands and throughout Alaska. In 1977, the North American river otter was listed in Appendix II of the Convention on International Trade in the Endangered Species of Wild Fauna and Flora (CITES). River otters are known to inhabit areas in Florida, especially throughout the Everglades. Big Cypress National Preserve (BCNP) is located in South Florida and is managed by the Department of Interior (DOI). Though no study has been devoted to estimating otter population size, the BCNP wildlife biologist has noted that the population has visibly been declining in her 30 years of service at the preserve. Recently, invasive species of constrictor snakes have overrun BCNM and this raises the concern that these snakes may have reduced the population of river otters in BCNP. BCNP is divided into 5 habitat types; Hammock, Pine, Cypress, Cypress-prairie, and Prairie. Of the five habitats river otters have been found in Hammock, Pine, and Cypress. The three habitats will be scouted to find suitable sampling stations. These stations will be regularly checked for a year by walking transects and scouting river banks from a canoe in search of scat, tracks, dens, or live animals. Stations will also be monitored with scent track plate stations, and baited camera traps. This investigation will provide a thesis project for an NSU Oceanographic Center graduate student, and undergraduates in the NSU Farquhar College of Arts and Sciences will participate in analyzing camera captures, fecal samples and other data.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
