Patrones estructurales de los manglares en geoformas y regiones del Pacífico sur mexicano

Background: Mangroves are communities whose structure expresses patterns according to the coastal landforms in which they develop. Questions: Is there a structural variation of mangroves among landforms and regions of the South Pacific? What is the effect of the geomorphological-regional factor on the structure of mangroves? What is the level of consistency of mangrove structure within each analyzed landform and region? Data description: Basal area, height, density, complexity index, and importance value. Study site: Mangroves from 39 systems in five hydrological regions in the states of Guerrero, Oaxaca, and Chiapas, Mexico. Methods: The structural classification of mangroves was carried out considering the landform (inlet, estuary, lagoon) and the hydrological region. Correlations were used to assess their relationship with salinity and water recharge, and multivariate techniques were employed to identify differences between factors and clustering patterns. Results: Density and basal area correlated positively with water recharge, and it was found that mangrove density and complexity varied significantly among landforms and regions, while basal area and height were affected by landform and region. Discrete groups of variables in ordinations were not evident, with greater structural variability of mangroves found by hydrological region rather than landform. Conclusions: There is structural variation in mangroves among landforms and regions of the South Pacific; however, the variation in basal area, height, and density is low, resulting in consistency when compared across hydrological regions. Antecedentes: Los manglares son comunidades cuya estructura expresa patrones de acuerdo a las geoformas costeras en las que se desarrollan. Preguntas: ¿Existe una variación estructural de los manglares entre geoformas y regiones del Pacífico sur? ¿Cuál es el efecto del factor geomórfico-regional sobre la estructura de los manglares? ¿Cuál es el nivel de consistencia de la estructura de los manglares entre cada geoforma y región analizada? Descripción de datos: Área basal, altura, densidad, índice de complejidad y valor de importancia. Sitio de estudio: Manglares de 39 sistemas de cinco regiones hidrológicas en los estados de Guerrero, Oaxaca y Chiapas, México. Métodos: La clasificación estructural de los manglares se realizó considerando la geoforma (bocana, estero, estuario, laguna) y la región hidrológica. Se emplearon correlaciones para evaluar su relación con la
