Estructura poblacional de Encyclia pyriformis (Orchidaceae) en Los Pretiles, Pinar del Río, Cuba / Population structure of Encyclia pyriformis (Orchidaceae) in Los Pretiles, Pinar del Río, Cuba
Bibliographic record
Abstract
RESUMEN\nLa familia Orchidaceae es una de las más numerosas de las plantas vasculares, tanto a nivel mundial como en Cuba. Encyclia pyriformis es una orquídea cubana endémica de las arenas blancas de la región occidental del país. Los estudios poblacionales en esta especie son inexistentes, por lo que el objetivo de esta investigación es la caracterización de su estructura poblacional en la Reserva Ecológica “Los Pretiles”, Mantua, Pinar del Río, Cuba. Se marcaron 39 parcelas en la zona de arenas blancas, en cada una de las cuales se contó el número de individuos de E. pyriformis. A cada individuo se le midió la altura, el diámetro del pseudobulbo correspondiente a la hoja mayor, así como el ancho y largo de la misma. En la zona muestreada se encontraron 141 individuos de E. pyriformis, para una densidad poblacional de 3,61 individuos/m2. Las clases de edad predominantes fueron la segunda y la tercera, lo que evidencia que la población está bien establecida.\n\n\nPalabras clave: Acoelorrhaphe wrightii, epífitas, forófito, orquídea, arenas blancas\n\nABSTRACT\nThe Orchidaceae is one of the most numerous families of vascular plants, at a worldwide level as well as in Cuba. Encyclia pyriformis is a species\nof Cuban orchid, endemic of the white sands areas in the western region of the country. As there are no population studies on this pecies, the\ngoal of this research is to typify its population structure in the Ecological Reserve of “Los Pretiles”, Mantua, Pinar del Río, Cuba. We marked 39 plots in the White Sands area and counted in each plot, the number of individuals of E. pyriformis. For each individual we measured the height,\nthe diameter of the pseudobulb from the larger leaf and the width and length of this leaf. In the sampled area 141 individuals of E. pyriformis,\nwere found for a population density of 3.61 individuals/m2. The predominant age classes were the second and third class, which indicates a well established population.\n\n\nKeywords: Acoelorrhaphe wrightii, epiphytes, host plant, orchid, white sand\nRecibido: diciembre 2016 Aceptado: marzo 2017

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.
