Diet, Diel Activity Pattern, Habitat Use, and Reproductive Effort of<i>Hylodes nasus</i>(Anura: Hylodidae) in One of the World's Largest Urban Parks (Tijuca National Park), Southeastern Brazil
Bibliographic record
Abstract
Hylodes nasus is a hylodid frog species that inhabits streams in the Brazilian Atlantic Rainforest of southeastern Brazil. It is endemic to the Tijuca Massif, which includes one of the largest urban forests in the world, the Tijuca National Park, in Rio de Janeiro. We studied the diet, activity period, habitat use, and reproductive effort of H. nasus during its reproductive period. Our results showed that the species has a wide spectrum of prey items (21 categories) but feeds mainly on five prey categories (Diptera, Formicidae, Coleoptera, larvae, and other Hymenoptera). The species is diurnal and tends to present a slight decrease in activity near midday. We noted a change in microhabitat use between active (diurnal) and inactive (nocturnal) periods: active individuals mainly occupied stones, whereas inactive individuals mainly occupied low vegetation. The ovarian complement comprises a median of 88 oocytes with a mean diameter of 2.2 mm. The gathered information consists in a first approximation of the biological and ecological characteristics of the species.
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.
