          Abstract

          Resumen Antecedentes: Los tolchés son franjas de árboles dentro del paisaje agrícola yucateco; proporcionan varios servicios ecosistémicos, incluyendo el suministro de material leñoso. Preguntas e hipótesis: ¿Existen diferencias en la estructura de la vegetación leñosa de los tolchés a lo largo de la distancia al pueblo y la intensidad de uso? La hipótesis es que los atributos estructurales de la vegetación de los tolchés son afectados negativamente por la intensidad del uso del bosque, que disminuye de los márgenes del poblado, al área agrícola, hasta llegar a la vegetación madura. Descripción de datos: Se evaluaron los atributos estructurales de tolchés y vegetación madura (VM), se realizó una rarefacción para estandarizar el esfuerzo de muestreo, un modelo lineal univariante seguido de pruebas a posteriori. Sitio y años de estudio: El estudio se realizó en tolchés y VM de Yaxcabá, Yucatán, de febrero a julio de 2019. Métodos: Se establecieron 44 unidades de muestreo (UM): 36 UM se ubicaron en tolchés, de 3 grupos diferenciados por su distancia al poblado y 8 UM se ubicaron en VM. Se registraron los individuos leñosos > 2.5 cm de DAP y se evaluaron las diferencias de los valores estructurales de ambas condiciones. Resultados: La diversidad de los tolchés fueron significativamente superiores a la alcanzada por la VM, relacionada a la distancia al poblado. Conclusiones: Se determinó la influencia de un patrón de aprovechamiento basado en la distancia al poblado. Niveles intermedios de aprovechamiento favorecen la riqueza y diversidad de los tolchés.

          Abstract Background: Tolchés are tree strips within agricultural matrix in Yucatan; they provide ecosystem services, including woody material supply. Questions and Hypotheses: Are there differences in the structure of the woody vegetation of the tolchés throughout the distance of the town and intensity of use? We hypothesize that structural attributes of the tolchés are negatively affectedby the intensity of forest use that is decreasing, from the margins of the town to the agricultural area, until reaching the mature vegetation. Data description: The structural attributes of tolchés and mature vegetation (VM) were evaluated, a rarefaction analysis was performed to standardize the sampling effort, and a univariate linear model followed by ex post tests were used. Site and years of study: The study was carried out in tolchés and VM of Yaxcabá, Yucatán, from February to July 2019. Methods: 42 sampling units (MUs) were established: 32 MUs were located in tolchés, from 3 groups differentiated by their distance from the town and 8 MUs were located in VM. All woody individuals > 2.5 cm dbh were recorded and the differences in the structural values both conditions were evaluated. Results: The diversity of the tolchés were significantly higher than that achieved by the VM related to the distance to the town. Conclusions: The influence of a harvesting pattern based on the distance to the town was determined. Intermediate levels of use favor the wealth and diversity of the tolchés.
