A Field Guide to the Amphibians and Reptiles of the Maya World: The Lowlands of Mexico, Northern Guatemala, and Belize, by Julian C. Lee [Review]
Bibliographic record
Abstract
Amphibians and reptiles do not generate the constant degree of general field-naturalists' attention, travel, and consequent book demand that birdwatching does and therefore the appearance of a field guide to them for an area south of North America and Europe is an event.A Field Guidé to the Amphibians and Reptiles of the Maya World is such a book.It is of general interest as amphibians and reptiles (in contrast to birds) are non-migratory, except for marine turtles, and therefore only the latter may actually share individuals with the northern hemisphere.Other groups have long evolved independently and the southern herpetofaunas have not been periodically eradicated through the Pleistocene by repeated glaciations.Most field guide coverage is defined by continents or "artificially" (from a biological point of view) by political units: countries, states, or provinces.In this guide to the Mayan world, the choice taken breaks from this tradition by selecting a geographical block lying north and northeast of the 600-metre contour in the highlands Alta Verapaz, Guatemala, and the Meseta Central of Chiapas, Mexico.The area includes the southern Mexican states of Yucatan, Quinta Roo, Campeche, and portions of Tabasco and Chiapas, as well as the countries of Belize and Guatemala and portions of Honduras.The lowlands thus focused on were the home of the indigenous people of the Yucatan peninsula, the Maya, hence the book's title.The guide begins with the mandatory Preface and Acknowledgments.These are followed with an Cook, Francis R. 2002."A Field Guide to the Amphibians and Reptiles of the Maya World: The Lowlands of Mexico, Northern Guatemala, and Belize, by

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.
