dc.descriptionThe flower flies are fundamental pollinators at highlands such as Andean forests. The hoverfly-plant interactions were evaluated based on pollen consumption in three vegetation covers in a mountain-forest zone in Bogotá. The consumed pollen was extracted from 358 hoverflies specimens by dissection of their digestive tract. The pollen grains were subsequently acetolized and mounted. 300 pollen grains were characterized and categorized per hoverfly according to their size and ornamentation. Bipartite interaction networks were used to assess the degree of specialization, connection and nestness of each network. Hoverfly-plant interactions at all vegetation covers were generalist. A high vulnerability and less stability were found at the Discontinuous Urban Fabric bipartite network, in contrast to the Riparian Forest that has low vulnerability and high stability indicating greater resilience of anthropized covers in the face of extinction events.en-US
dc.descriptionLas moscas de las flores son polinizadores fundamentales en hábitats de alta montaña como el bosque altoandino. Se evaluó la relación Sírfido-planta asociada al consumo de polen en tres coberturas vegetales de una microcuenca cercana a Bogotá. El polen consumido por 358 sírfidos fue extraido tras la disección de su tracto digestivo, y posteriormente acetolizado y montado. Se analizaron 300 granos de polen por sírfido y se categorizaron según su tamaño y ornamentación. Para caracterizar las relación Sírfido-planta se emplearon redes de interacción bipartitas que muestran el grado de especialización, conectancia y anidamiento de cada red-cobertura. Las relaciones de los Sírfidos en las coberturas estudiadas se mostraron generalistas, se encontró mayor vulnerabilidad y menor estabilidad de la red bipartita del Tejido Urbano discontinúo en contraste con respectiva del Bosque Ripario, lo que indica mayor resiliencia de coberturas antropizadas ante eventos de extinción.es-ES
