Estudio demográfico de Mammillaria mystax en Cañada Morelos, Puebla, México
Bibliographic record
Abstract
Mammillaria mystax es una cactacea globosa endemica de Mexico, se localiza en Guerrero, Oaxaca y Puebla, se utiliza como ornamental y se encuentra en el Apendice II del cites. Se evaluaron los parametros demograficos de una poblacion de la especie en Canada Morelos, Puebla y se determino la tasa de crecimiento poblacional por medio del modelo matricial de Lefkovitch. La densidad fue de 0.046 individuos/m2 , los individuos adultos fueron los mas abundantes y las plantulas constituyeron la menor proporcion. Las plantas presentaron crecimiento lento y alta supervivencia. El periodo reproductivo se observo de octubre a julio y la germinacion fue escasa. La tasa de crecimiento (l=1.15+0.25) indica que la poblacion esta en equilibrio; sin embargo, la baja densidad, una estructura de tamanos constituida en su mayoria por adultos, escasa germinacion de semillas y baja supervivencia de plantulas sugieren que esta especie puede ser vulnerable a la extincion

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.
