Resumo: | Urban avifaunal surveys in Brazil have been increasing in recent years, despite none of them consisting of long-term studies indicating events of regional colonization and/or missing species. Here, we present an avifaunal survey of an urbanized ecosystem in southeastern Brazil, carried out along 30 years, on the campus of the Pontifícia Universidade Católica de Minas Gerais, municipality of Belo Horizonte, Minas Gerais state. Inside the campus there is a forest reserve adjacent to a small lake. The inventory was mainly based on opportunistic records from the years 1982-2013. We recorded 134 bird species along the past 30 years. However, the present avifauna is composed of 123 species. A total of 97 species was recorded in the reserve, including the forest fragment and the adjacent lake, of which 44 were exclusive to this area. Nevertheless, the majority of the current species found in the study area is forest independent (N = 51) or semi-dependent (N = 46). There is a predominance of insectivorous (N = 43) and omnivorous (N = 29) species. The current avifauna is represented by 15 migratory species, which can be found both in the urbanized area and in the forest remnant. However, the majority of the species (N = 75) is resident in the area, including three invasive species, whereas few others (N = 28) are occasional visitors. The remaining species were probably introduced in the area. There were 11 cases of disappearing species, which include typical forest birds, and also species typical of wetlands and rural environments. We also comment on recent colonization and on the possible effects of isolation on birds. Probably, the majority of forest-dependents are on the brink of extinction in the forest fragment. Thus, the species' list provided here can be useful as a database for monitoring long-term effects of urbanization on this bird community. |

Neste estudo, apresentamos um levantamento da avifauna de um ecossistema urbano do sudeste brasileiro, efetuado ao longo de 30 anos, no campus da Pontifícia Universidade Católica de Minas Gerais, município de Belo Horizonte, estado de Minas Gerais. Dentro do campus há uma pequena reserva florestal adjacente a um pequeno lago. O inventário foi baseado principalmente em registros aleatórios ao longo de 1982-2013. Foram registradas 134 espécies de aves neste período. Entretanto, a avifauna atual é composta por 123 espécies. Um total de 97 espécies foi registrado na reserva, representada pelo fragmento florestal e pelo lago adjacente, das quais 44 foram exclusivas a esta área. Todavia, a maior parte das espécies de aves que ocorrem atualmente na área de estudo é independente (N = 51) ou semi-dependente (N = 46) de florestas. Há um predomínio de espécies insetívoras (N = 43) e onívoras (N = 29). A avifauna atual é representada por 15 espécies migratórias, que podem ser encontradas tanto na área urbanizada quanto no remanescente florestal. Entretanto, a maioria das espécies (N = 75) é residente na área, incluindo três invasoras, enquanto outras (N = 28) são representadas por visitantes ocasionais. O restante das espécies foi possivelmente introduzido na área. Houve 11 casos de desaparecimento de espécies, que incluem espécies típicas de matas, áreas úmidas e ambientes rurais. Também comentamos sobre colonizações recentes e sobre possíveis efeitos do isolamento nas aves. Provavelmente, a maior parte das espécies dependentes de florestas está próxima à extinção local no fragmento florestal. Assim, o presente levantamento pode ser útil como uma base de informações para monitoramentos de longo prazo sobre os efeitos da urbanização sobre esta comunidade de aves.Papéis Avulsos de Zoologia2018-01-24T16:36:57Z2018-01-24T16:36:57Z2013-06-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf18070205http://dx.doi.org/10.1590/S0031-10492013002500001http://www.locus.ufv.br/handle/123456789/16789engv. 53, n. 25, p. 327‐344, 2013Peixoto, Helberth José CardosoVasconcelos, Marcelo Ferreira deDutra, Eduardo de CarvalhoMazzoni, Luiz GabrielPedroso, Letícia FerreiraPerillo, AlyneValério, Fernando AugustoGuerra, TadeuPetrocchi, DiegoMorais, RodrigoSantos, Lucas Penna SoaresGarzon, BrunoDias, Juan Espanha MoreiraSantos, José Enemir dosMorais, Allan Suhett deGuimarães, Letícia Souza LimaGarcia, Frederico Innecco Alveset al.info:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:33:17Zoai:locus.ufv.br:123456789/16789Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:33:17LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
