LUQUE FERNANDEZ, César R; CANO SANZ, Luis G  and  PENA DOMINGUEZ, Yuri A. Richness and abundance of birds in an urban gradient of Arequipa, southwest of Peru. Arnaldoa [online]. 2018, vol.25, n.3, pp.1095-1106. ISSN 1815-8242.

The importance of knowing the effect of the advance of urbanization on biodiversity is becoming increasingly important, so it is necessary to increase the number of investigations in these environments. This study was conducted in the city of Arequipa, Peru, trying to cover urban, suburban and rural environments, relating the effects on the richness and abundance of birds on this gradient, finding during the study period a lower richness of bird species in urban environments with dominance of some species (Columba livia and Turdus chiguanco), while in rural environments there were greater equity of abundance and greater richness of species. More studies are needed on a long time scale to have a better understanding of this dynamic.
