Bats of St. Kitts (St. Christopher), northern Lesser Antilles, with comments regarding capture rates of Neotropical bats
Bibliographic record
Abstract
Only four species of bats have been previously reported from the Antillean island of St. Kitts—Noctilio leporinus, Artibeus jamaicensis, Molossus molossus, and Tadarida brasiliensis. Our field research reported herein adds three species to this list—Monophyllus plethodon, Ardops nichollsi, and Brachyphylla cavernarum. These efforts included mist netting in a variety of foraging habitats and extensive surveys of natural and anthropogenic roost sites. We discuss the difficulty in accurately reporting mistnetting effort and capture rates. The average rate of fruit bat captures during 2001 on St. Kitts (1.11 bats per net-night - BNN) falls towards the lower end of the range (0.65-2.47 BNN) reported from nearby islands in the northern Lesser Antilles and the lower end of the range (2.20-5.93 BNN) reported for mainland populations of neotropical fruit bats. We discuss possible causes of these decreased population levels, such as the impact of recent hurricanes and competition from the large population of vervet monkeys (Cercopithecus sabaeus) found on St. Kitts.

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.
