Conservation Status of Caiman latirostris (Crocodylia: Alligatoridae) in Disturbed Landscapes of Northwestern Uruguay
Bibliographic record
Abstract
Demographic studies on crocodilians in subject to strong human disturbance habitats are scarce, particularly in the Neotropical Region. This work provides the first survey data of abundance and population size structure of a neotropical caiman, Caiman latirostris, in disturbed habitats of northwestern Uruguay (30°S, 57°W). We conducted nocturnal surveys in agriculture impoundments (2–116 ha) of the Ñaquiñá and Lenguazo stream basins during summer, from 2001 to 2004. About 81% of impoundments were inhabited by caiman, with relative abundance indices between 2.1 and 4.4 × km−1. Population size structure in the study area was similar throughout the study period; sub-adults from 50 to 119 cm of total length were the most abundant (57–78%), followed by adults (25–33%), and juveniles (6–22%). Relative abundance indices suggested that C. latirostris is not seriously endangered in contrast to previous local reports. The construction of agriculture impoundments in northwestern Uruguay for irrigation of rice and sugar cane seem to have been favored C. latirostris, as indicated by population size structure.

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.
