Avifauna em cemitérios da área urbana no domínio do Cerrado, Sudeste do Brasil: riqueza e composição de espécies da comunidade

Abstract

Cemeteries are classified as urban green areas, being conducive to the establishment and maintenance of various species of birds. In this sense, cemeteries contribute to the conservation of biodiversity in urban spaces. The present work had as objective to determine the richness and to evaluate the composition of the avifauna in the cemeteries of the Urban Area of Uberlândia, MG.The study was carried out in three cemeteries (Bom Pastor, São Pedro and Buritis), from August 2017 to October 2018. We employed the sampling method for transections. The Sorensen coefficient of similarity was calculated to evaluate the composition of the avifauna. A total of 96 bird species were registered, being 68 species in Area 1; 64 in Area 2 and 66 in Area 3.The Sorensen coefficient showed greater similarity in the composition of the avifauna between Areas 1-2, and smaller between Areas 2-3. The Area 3 presented the largest number of exclusive species (15 species). Most of the registered species are formed by generalists who inhabit different spaces of the urban network. Among the registered species, the following stand out: Suiriri islerorum, species "almost threatened", according to the IUCN Red List; and Cyanocorax cristatellus, as the only endemic Cerrado species. We conclude that the city's cemeteries sustain a significant bird species richness and that the composition of the avifauna in the Areas investigated is closely related to the geographic spaces and their environment matrix.
