Abstract
Amphibians, the original pioneering land vertebrates, have survived their displacement from former dominance by more advanced vertebrates as numerous and diverse, generally relatively small, forms.These include the familiar and widely distributed frogs, the northern temperate and tropical American salamanders, and the tropical caecilians.These, however, are now regarded by many leading researchers as faced with a new wave of extinctions due to increasing loss of habitat, chemical residues pollution, and the spread of devastating disease.As a consequence, their study and habitat management is widely pronounced as an immediate world conservation priority.It is estimated that of the 6400 modern species described to date, one-third are threatened and 168 are judged now extinct.As well, an unknown number of yet undescribed species may disappear before they are found.The purpose of this book is present a comprehensive survey of the current state of research on amphibians.To accomplish this, editor Dodds has enlisted contributions from 52 herpetologists.Americans dominate, only nine are from elsewhere, one each residing in Australia, Brazil, Germany, France, Panama, Russia, Switzerland, Tanzania, and the United Kingdom.That none are from Canada does not fairly reflect the active research and conservation initiatives, past and current, here.The text is divided into six parts containing 27 chapters in all.Part 1 is an overview on diversity and life history ending with why amphibian declines matter, and a chapter on field study objectives.Chapters in Part 2 concentrate on larvae and included chapters are on morphology, sampling, dietary assessments; mesocosms, and water quality criteria.Part 3 focuses on juveniles and adults containing chapters on measuring and marking post-metamorphs, egg mass and nest count, dietary assessments of adults, movement patterns and radiotelemetry, field enclosures and terrestrial cages.Part 4 deals with population: drift fences,

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.
