Fenología y potencial de almacenamiento de carbono de Picea martinezii T.F. Patterson en ecosistemas forestales de Nuevo León.
Bibliographic record
Abstract
Con el proposito de contribuir al entendimiento del papel ecologico de Picea martinezii T.F. Patterson como almacenamiento de carbono, debido al tamano reducido de sus poblaciones y se encuentra en la Norma Oficial Mexicana NOM- 059-SEMARNAT-2010 en la categoria de peligro de extincion. Se establecio cuatro sitios permanentes de muestreo de 50 x 50 m (2500 m2) en Agua de Lardin en el municipio de Aramberri, El Butano en el municipio de Montemorelos, La Canada El Bosque y La Canada La Tinaja en el municipio de General Zaragoza en el estado de Nuevo Leon. A todos los individuos arboreos se les midieron las variables dendrometricas: el diametro (DAP) y la altura total (h). Se hizo un analisis de los datos obtenidos para determinar la diversidad de especies mediante el indice del valor de importancia (IVI), el indice de Jaccard, ademas la estructura se evaluo mediante la distribucion de diametros para la distribucion horizontal y el indice (A) de Pretzsch, para la distribucion vertical de especies. Ademas, mediante los datos obtenidos en campo se utilizo la informacion para elaborar una tabla de volumen de la especie aplicando diferentes modelos matematicos ensayados, una vez obtenido el volumen por categoria diametrica se calculo el contenido de carbono mediante una ecuacion alometrica, y esta a su vez permitio estimar la produccion de oxigeno que esta especie brinda. Este estudio aporta las bases para el entendimiento y manejo sustentable de los recursos naturales, bajo el principio de los servicios ambientales. ABSTRACT With the purpose to contribute to the understanding of ecological role of Picea martinezii T.F. Patterson as carbon storage, due to the small size of its populations and is in Official Mexican Standard NOM-059-SEMARNAT-2010 in the category of danger of extinction. Four permanent sampling sites of 50 x 50 m (2500 m2) were established in Agua de Lardin in the municipality of Aramberri, El Butano in the municipality of Montemorelos, La Canada El Bosque and La Canada La Tinaja in the municipality of General Zaragoza is the state of Nuevo Leon. The dendrometric variables were measured for all tree individuals: diameter (DAP) and total height (h). (IVI), the Jaccard index, the structure was evaluated by the distribution of the diameters for the horizontal distribution and the Pretzsch index (A) for the vertical distribution of species. A table of volume of the species was compiled and the carbon content calculated as well as the production of this kind of fuel as oxygen.
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.
