Unveiled diversity: Amazonian Campinaranas harbor twice the number of bryophyte species recorded in the last century
Bibliographic record
Abstract
Campinaranas are unique vegetation patches in the Amazonian biome, characterized by white-sand soils with relatively low nutrient content and subject to periodic flooding coupled with fluctuating groundwater levels. This study aimed to produce a synopsis of the bryophyte flora in Campinarana habitats by combining information from the literature with new collections made in the Uatumã Sustainable Development Reserve (Balbina, Central Amazonia), and areas of the middle Uaupés river (São Gabriel da Cachoeira, upper Rio Negro). One hundred and forty-three species were identified among mosses and liverworts, of which 68 are reported for the first time in Campinaranas. The species Frullania rio-janeirensis, Ceratolejeunea filaria, Diplasiolejeunea cobrensis and Bazzania diversicuspis are new records for the state of Amazonas. These results reveal high species richness for Campinaranas and indicate the need for continued study in this underexplored Amazonian habitat. This study emphasizes the importance of carrying out floristic inventories in poorly known environments and of further studies with different approaches, such as ecological, phytogeographic and genetic efforts.
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.
