Rediscovery of Rhipsalis ewaldiana Barthlott & N.P. Taylor (Cactaceae): notes of morphology and conservation of an endemic and threatened species from the Brazilian Atlantic Forest
Bibliographic record
Abstract
Cactaceae Juss. is a family which comprises 124 genera and about 1438 species distributed from Canada to Patagonia, with the largest diversity in tropical and subtropical regions of Americas (see e.g., Hunt et al. 2006). The flora of Brazil includes 39 Cactaceae genera and 261 species, of which 14 genera and 54 species can be found the Rio de Janeiro state, highlighting the importance of this state to the biodiversity of Brazilian cacti (see BFG 2015). These species are highly affected by anthropic disturbances, which cause rapid habitat destruction, especially affecting the narrowly distributed endemic taxa, with 31% of the family being threatened, demonstrating the high anthropogenic pressures on the biodiversity in arid lands (Goettsch et al. 2015).
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.
