| description | Background and Aims: Thunbergia alata is one of the ten most problematic invasive plant species in Colombia. Its rapid colonization and adaptation to Andean forests have affected the composition and structure of indigenous plant communities. In this research, analysis of functional traits was carried out, generating new information that could explain the rapid colonization, adaptation and invasive potential of T. alata in this type of Andean environment. Methods: To obtain this information, a series of observations were made on the morphology and anatomy of roots, stems, leaves, flowers, fruits and seeds. Likewise, a characterization of its floral visitors and symbiotic relationships with soil microorganisms was carried out. Key results: We determined that both morphological traits and interaction phenomena favour the adaptability of T. alata in Andean forests and could contribute to a greater extent to its active colonization in this type of environment. An active association of T. alata was found with different species of native and introduced floral visitors, with a total of 2266 floral visits made during our study by seven species of insects belonging to the orders Coleoptera and Hymenoptera. Mycorrhizal fungal spores associated with T. alata populations were found at all sampling sites. The number of spores per 100 g of soil varied between 300 and 424. All the roots of T. alata, without exception, had high colonization by arbuscular mycorrhizal fungi. Conclusions: We believe that the information obtained in this research will contribute to the generation of comprehensive and effective strategies for the control of this species in Andean forests. |

Antecedentes y Objetivos: Thunbergia alata es una de las diez especies de plantas invasoras más problemáticas de Colombia. Su rápida colonización y adaptación a los bosques andinos ha afectado la composición y estructura de las comunidades vegetales nativas. En esta investigación se realizó un análisis de rasgos funcionales, generando nueva información que podría explicar la rápida colonización, adaptación y potencial invasor de T. alata en este tipo de ambientes andinos. Métodos: Para obtener esta información se realizó una serie de observaciones sobre la morfología y anatomía de raíces, tallos, hojas, flores, frutos y semillas. Asimismo, se realizó una caracterización de sus visitantes florales y de las relaciones simbióticas con los microorganismos del suelo. Resultados clave: Se determinó que tanto los rasgos morfológicos como los fenómenos de interacción favorecen la adaptabilidad de T. alata en los bosques andinos y podrían contribuir en mayor medida a su colonización activa en este tipo de ambientes. Se encontró una asociación activa de T. alata con diferentes especies de visitantes florales nativos e introducidos, con un total de 2266 visitas florales realizadas durante nuestro estudio por siete especies de insectos pertenecientes a los órdenes Coleoptera e Hymenoptera. En todos los sitios de muestreo se encontraron esporas de hongos micorrizógenos asociadas a las poblaciones de T. alata. El número de esporas por 100 g de suelo variaba entre 300 y 424. Todas las raíces de T. alata, sin excepción, presentaban una alta colonización por hongos micorrizógenos arbusculares. Conclusiones: Creemos que la información obtenida en esta investigación contribuirá a la generación de estrategias integrales y efectivas para el control de esta especie en los bosques andinos.
