Abstract
Anthropogenic processes are constantly shaping the tree structure and species composition in ecological communities resulting in novel forests. Understanding novel forestโ€™s response to anthropogenic and natural processes will provide insight for future conservation and management decisions. The tree structure and species composition of coastal novel forests dominated by Terminalia catappa were sampled in twelve study sites in the North-Western coasts in the moist region of Puerto Rico before and after Hurricane Marรญa using the Point-center Quarter Method (PCQM). My study suggests that forests located on slope had a significantly lower percentage of non-native species when compared among other landforms. The forestsโ€™ previous land use, pH, soil order and series had an effect on species composition. I also found that the distance to the trajectory of Hurricane Marรญa had a no effect on tree structure, species composition, and functional composition.
Los procesos antropogรฉnicos moldean la estructura de los รกrboles y la composiciรณn de las especies en las comunidades ecolรณgicas. Comprender la respuesta de los bosques noveles a los procesos antropogรฉnicos y naturales proporcionarรก informaciรณn para futuras decisiones de conservaciรณn y gestiรณn. Se tomaron muestras en bosques costeros noveles dominados por Terminalia catappa en doce sitios de estudio en el noroeste de la regiรณn hรบmeda de Puerto Rico antes y despuรฉs del huracรกn Marรญa utilizando el Mรฉtodo de Punto-Centro Cuarto. Los bosques localizados en pendientes tienen un porcentaje significativamente menor de especies no nativas en comparaciรณn con otras formas de terreno. El uso anterior de la tierra, el pH, el orden y las series de suelo en los bosques tuvieron un efecto en la composiciรณn de especies. La distancia a la trayectoria del huracรกn Marรญa no tuvo ningรบn efecto sobre la estructura de รกrboles, especies y composiciรณn funcional.
