A composição da avifauna do campus da Universidade Estadual de Londrina, norte do Paraná, Brasil

Abstract

This study analyzed the spatial distribution of the Universidade Estadual de Londrina’s (UEL) avifaunal in several habitats (forest, scattered trees, buildings and surroundings, shrubs, aquatic and grassland). Besides that, a comparative analysis about the richness and composition of species and the guild structure of forest birds was carried out between the bird community witch was recorded in a forest remnant of Universidade Estadual de Londrina campus and the bird communities of one forest remnant in a country area, two forest remnants in an urban area and a continuous forest area. Field data were derived by transect count from January 2001 to December 2002 in 48 samples. A total of 174 species were recorded, being the forest and scattered trees habitats the highest species richness, while the aquatic and the grassland habitats presented the lowest species numbers. The species richness recorded at the campus forest remnant was similar to that recorded in a continuous forest area and a country area and higher than the one recorded in a urban area. The Sorensen index showed similar and relatively high values between the campus and the four other areas. On another hand, the guild structure of forest birds of the campus showed greater similarity to that an urban area and a country area (Spearman rank correlation
= 0,5). At the campus and also in a urban area, a diminution of the large frugivorous and creeper species occurred and an increase of forest edge species related to a continuous forest area and a country area.
