Fishing behaviour and novel geographic records of Speothos venaticus (Carnivora: Canidae) in the department of Madre de Dios, Peru.
Bibliographic record
Abstract
The bush dog (Speothos venaticus) is a rare and elusive canid with a patchy distribution across the Amazon rainforest and other Neotropical biomes. Known for its social behavior and unique adaptations for cooperative hunting, the species is closely associated with dense understory vegetation and aquatic habitats. This study documents novel geographic records and a behavioral observation of S. venaticus in the Madre de Dios region of southeastern Peru, a poorly understood part of their range. We report a direct observation of a family group exhibiting foraging behavior in a riparian habitat, with an adult individual actively fishing in a small tributary of the Las Piedras River while juveniles observed. Additional records from four tributaries of the Madre de Dios watershed further underscores the species’ association with riverine systems within primary lowland rainforests.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
