Deteniendo el tráfico: reorganización de senderos de hormigas cortadoras de hojas tras su obstrucción en dos ambientes de bosque tropical húmedo

Abstract

Las actividades humanas alteran la distribución y disponibilidad de los recursos para las especies, afectando negativamente a la biodiversidad. Se sabe que las hormigas cortadoras de hojas incrementan su adecuación en ambientes antropizados, como son las zonas de borde, remanentes de bosque pequeños y acahuales (bosques secundarios). Estos cambios pueden modificar las distintas dinámicas de forrajeo que incluyen cambios en el arreglo espacial y mantenimiento de los senderos de forrajeo. En este contexto, nosotros evaluamos el tiempo de reorganización de los senderos (TRS) de hormigas cortadoras de hojas (Atta cephalotes) ante una interrupción física para dos tipos de ambientes: bosque y acahual en función del flujo de hormigas por unidad de área (caudal). Encontramos que las hormigas siempre restituyeron su trayectoria original, independientemente del tipo de ambiente analizado. Nuestros resultados sugieren que el uso óptimo de los senderos de forrajeo amortigua los cambios en el TRS, permitiendo un aprovechamiento similar de las fuentes de recursos disponibles en ambientes diferentes. Por lo tanto, concluimos que la capacidad de reorganizar senderos de A. cephalotes no es dependiente del grado de perturbación al que se exponen las hormigas en ambientes tropicales antropizados.
