Variación espacio-temporal de la comunidad de aves y sitios de anidaciòn en tres parques urbanos de Guadalajara, Jalisco, México.

Abstract

Urbanization transforms wildlands into man-made systems. Within the urban landscape, urban green areas represent the last remnants of greenery within large city boundaries. However, urban green areas, offer food and refugee to different bird species. Birds play an important ecological role as pollinators, predators and seed dispersers, but our understanding of the processes that determine how bird communities respond to urbanization is still basic. Urban parks differ in surface area, topography and vegetation structure, so, we analyzed how bird communities differed in space and time in three urban parks in the Guadalajara Metropolitan Area. The results show that site and landscape variables explained bird community’s diversity. The strongest relationship was the distance to the nearest Natural Protected Area. But the presence of most of the species was related to tree and shrub species and abundance. Guadalajara Metropolitan Area parks showed to be different in their characteristics, making it a place with a wide array of resources available to the bird community.
