Resumo: | Birds are considered sensitive to human disturbance because they have a close relationship with the environmental conditions. In the caatinga, modification of habitat ocurred by a historical process of environmental deterioration as a result of unsustainable use of natural resources. Due to the extreme climatic conditions of the caatinga, it is expected that a more resilient biota survives in this vegetation under to human interventions than those in more stable environments, such as tropical rainforests. Thus, the present study aimed to investigate the effects of habitat loss on a bird community of caatinga area type seasonal dry forest in the municipality of Candiba, Bahia, Brazil, comparing avifaunas occurring in an area of remnant forest (Area I) with adjacent matrix cleared of area (Area II). Six expeditions were conducted, three in the dry season and three in the rainy season, between November 2011 and July 2012. The method of Mackinnon lists was used for recording auditory and visual species. It was recorded 138 species, 92 in the Area I and 94 in the Area II. Both areas showed a low similarity (38%) between their specific compositions, demonstrating that only a small portion of the bird community in the region occurs in both habitat types, tolerating the different states of preservation. Regarding the trophic structure, insectivorous species predominated in both areas, with emphasis on the occurrence species of more specialized habits in only Area I, indicating that they are intolerant to habitat loss. In Area II, were representative species of bird generalist habits, such as granivorous and omnivorous, they seem to benefit from the replacement of native forests by agricultural lands. Although bird species of high sensitivity and forest dependents represented the minority, such species were directly affected by habitat change, since many of them were not recorded in the cleared matrix. Thus, habitat loss is a process that leads to negative effects on the bird community of seasonal dry forest, especially in species composition, which changes as the forest vegetation is removed. |

Na catinga, a modificação do habitat tem se dado por um histórico processo de deterioração ambiental, em decorrência do uso insustentável dos seus recursos naturais. Em função das condições climáticas extremas da caatinga, espera-se que nesta vegetação sobrevivam biotas mais resilientes a intervenções humanas do que aquelas de ambientes mais estáveis, como as florestas tropicais úmidas. Deste modo, o presente estudo objetivou investigar os efeitos da perda de hábitat sobre uma comunidade de aves de área de caatinga do tipo floresta estacional seca, no município de Candiba, Bahia, Brasil, comparando as avifaunas ocorrentes em uma área de remanescente florestal (Área I) com a da matriz desmatada adjacente (Área II). Foram realizadas seis expedições, três na estação seca e três na chuvosa, entre novembro de 2011 e julho de 2012. O método de listas de Mackinnon foi utilizado para o registro auditivo e visual das espécies. Foram listadas 138 espécies, sendo 92 na Área I e 94 na Área II. As duas áreas apresentaram uma baixa similaridade (38%) entre suas composições específicas, demonstrando que apenas uma pequena porção da comunidade de aves da região em ambos os tipos de habitat, tolerando os distintos estados de conservação dos mesmos. Quanto à estrutura trófica, as aves insetívoras predominaram tanto na Área I como na Área II, com destaque para ocorrência de espécies de hábitos mais especializados somente na Área I, indicando que são intolerantes à modificação de seu habitat. Na Área II, foram representativas as espécies de aves hábitos mais generalistas, como as granívoras e onívoras, que parecem se beneficiar da substituição de florestas nativas por áreas de cultivo agrícola. Ainda que as espécies de aves de alta sensibilidade e dependentes florestais representaram a minoria, tais espécies foram diretamente afetadas pela alteração do habitat, uma vez que muitas delas não foram registradas na matriz desmatada. Deste modo, a modificação do habitat se mostra como um processo que acarreta em efeitos negativos sobre a comunidade de aves de caatinga arbórea, sobretudo na composição das espécies, que é alterada à medida que a vegetação florestal é substituída por áreas agrícolas.Submitted by Ricardo Cedraz Duque Moliterno (ricardo.moliterno@uefs.br) on 2016-04-01T22:28:22Z No. of bitstreams: 1 Dissertação Vaniclézia de Andrade Melo.pdf: 1015149 bytes, checksum: f174db068eeaabe1f7c9615543e4f0a6 (MD5)Made available in DSpace on 2016-04-01T22:28:22Z (GMT).

The method of Mackinnon lists was used for recording auditory and visual species. It was recorded 138 species, 92 in the Area I and 94 in the Area II.
