An assesment of the ant community in a Neotropical urban area with different levels of disturbance

Summary: Traditionally, urban areas have been described as sites inhabited by a reduced number of animal species. However, the new spaces created represent a new niche that some species take advantage of. This work characterized the ant community in four different microhabitats in an urban area of Costa Rica. Bait sampling of ants revealed a total of 22 species, 20 of which are native species. Four adjacent areas were sampled: the interior of a building, two green areas, and an ecological reserve. Comparing these four areas, the two green areas showed the greatest similarity, while the building interior was the least similar. The results suggest that urban green areas can serve as reservoirs for native biodiversity. Tradicionalmente, las áreas urbanas han sido descritas como sitios habitados por un número reducido de especies animales. Sin embargo, los nuevos espacios creados podrían representar un nuevo nicho que algunas especies podrían aprovechar. Se caracterizó la comunidad de hormigas en cuatro diferentes microambientes en un área urbana de Costa Rica. Muestreos con cebos para hormigas muestran un total de 22 especies, de las cuales 20 son especies nativas. Se muestrearon cuatro áreas adyacentes: el interior de un edificio, dos jardines y una reserva ecológica. La comparación entre estas áreas, arroja que los dos jardines presentan la mayor similitud, mientras el interior del edificio es el menos similar. Los resultados sugieren que las áreas verdes en zonas urbanas pueden funcionar como reservorios para especies nativas de hormigas y posiblemente de algunos otros grupos.
