Microhabitat use of harvestmen (Arachnida: Opiliones) assemblage in the highland Brazilian Atlantic rainforest
Bibliographic record
Abstract
Brazilian Atlantic rainforest is one of the largest hotspots of biodiversity in the world, with the highest number of harvestmen (Arachnida: Opiliones) species per given area. Currently, however, information on the species richness or spatial distribution of these arachnids in this northeastern Brazilian biome is extremely scarce. We conducted a field study to examine the microhabitat use of harvestmen in a fragment of the highland Atlantic rainforest. Harvestmen fauna and the microhabitat preference were assessed by nocturnal active search across 3 months (September to November 2011). Three hundred and eighteen individuals of eight harvestmen species from seven microhabitats were sampled. Four species were categorized as generalists, colonizing five or six microhabitats, whereas three species showed microhabitat specificity, being found in only one or two microhabitats. The forest ground microhabitat revealed higher harvestmen species richness, indicating that the majority of the harvestmen assemblage is composed of ground-dwelling 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.
