| description | Background and Aims: Land use change generated by human activities has fragmented riparian corridors causing changes in the diversity and structure of its vegetation. The objective of this study was to compare the diversity, structure and floristic similarity in five sites of the Tacotalpa River, Tabasco, Mexico, related to vegetation variables with landscape metrics.Methods: Sampling was performed at five sites of the Tacotalpa River: Tapijulapa (s1), Arroyo Chispa (s2), Nuevo Madero (s3), Mexiquito (s4) and Oxolotán (s5). At each site, 20 sampling units of 10 × 10 m were established. Trees and shrubs with a DBH ≥1 cm were counted. The diversity and structure were compared with a one-way ANOVA. The floristic similarity between sites was compared with a Bray-Curtis cluster, Pearson correlation and PCA between vegetation variables and landscape metrics, using PAST and SPSS.Key results: There were 2589 individuals in 38 families, 92 genera and 119 species. The diversity 0D of s2 was statistically lower than s1 and s3, while 1D was similar in the five sites. The tree density of s1 was significantly greater than in s2, s3 and s5. The averages of DHB and height of s1 were low, showing significance with s2 (p <0.05). The floristic similarity ranged from 0.41 to 0.58. Order 0D diversity, shrub species and tree density correlated positively with some of the landscape metrics. The 1D diversity and tree species correlated positively with the paved road distance, and height with the dirt road.Conclusions: The differences between the sites suggest that there are different levels of disturbance along the Tacotalpa River. Positive correlations between vegetation variables and landscape metrics indicate that infrastructures near the river modify the diversity and structure of the riparian vegetation. |

Antecedentes y Objetivos: El cambio de uso del suelo generado por actividades humanas, ha fragmentado los corredores ribereños causando cambios en la diversidad y estructura de su vegetación. El objetivo de este estudio fue comparar la diversidad, estructura y similitud florística en cinco sitios del río Tacotalpa en Tabasco, México, relacionando las variables de vegetación con métricas del paisaje.Métodos: Se realizó un muestreo en cinco sitios del río Tacotalpa: Tapijulapa (s1), Arroyo Chispa (s2), Nuevo Madero (s3), Mexiquito (s4) y Oxolotán (s5). En cada sitio se establecieron 20 unidades de muestreo de 10 × 10 m. Los árboles y arbustos con un DAP≥1 cm fueron censados. La diversidad y estructura se comparó con un ANOVA de un factor. La similitud florística entre sitios se comparó con un cluster Bray-Curtis correlación de Pearson y ACP entre las variables de vegetación y métricas del paisaje, usando PAST y SPSS.Resultados clave: Se registraron 2589 individuos en 38 familias, 92 géneros y 119 especies. La diversidad 0D del s2 fue estadísticamente menor que en s1 y s3, mientras que 1D fue similar en los cinco sitios. La densidad de árboles del s1 fue significativamente mayor que s2, s3 y s5. Los promedios del DAP y altura del s1 fueron bajos, mostrando significancia con el s2 (p<0.05). La similitud florística osciló entre 0.41 a 0.58. La diversidad orden 0D, las especies arbustivas y la densidad de árboles se correlacionaron positivamente con algunas de las métricas del paisaje. La diversidad 1D y especies arbóreas se correlacionaron positivamente con la distancia de carretera pavimentada, y la altura con la de terracería.Conclusiones: Las diferencias entre los sitios sugieren que existen diferentes niveles de perturbación en el río Tacotalpa. Las correlaciones positivas entre las variables de vegetación y métricas del paisaje indican que las infraestructuras cercanas a la ribera modifican la diversidad y estructura de la vegetación ribereña.
