| Abstract | |
Conversion of lands to agroecosystems has resulted in a decline in bird biodiversity. Analyzing functional diversity is a central tool for detecting changes in the ecological functions performed by birds in these landscapes. This paper aims to investigate the responses of bird taxonomic and functional diversity to landscape heterogeneity and native forest cover in Neotropical vineyards. We sampled 19 vineyard landscapes in southeastern Brazil. These landscapes covered a gradient of forest cover and heterogeneity resulting from various land-uses. To assess bird diversity, we considered both taxonomic diversity and functional diversity (i.e., functional richness, evenness, and divergence). To examine the potential interactions between landscapes and bird assemblages, we employed generalized linear models (GLM). Taxonomic diversity showed no correlation with any landscape metrics. On the other hand, variation in the three metrics of functional diversity was related to landscape heterogeneity. However, in heterogeneous landscapes, these communities can be structured by limiting similarity processes. We highlight the negative impact of landscape homogenization on the ecological functions performed by birds in vineyards, while finding no significant effect on species diversity. These findings can provide valuable support for the formulation of public policies aimed at striking a balance between agricultural production and biodiversity conservation.Abstract in Portuguese is available with online material. A conversao global de terras em agroecossistemas resultou em declinio na biodiversidade de aves, e a analise da diversidade funcional e uma ferramenta importante para detectar mudancas nas funcoes ecologicas desempenhadas por aves nesses ambientes. Este artigo tem como objetivos investigar as respostas da diversidade taxonomica e funcional de aves a heterogeneidade da paisagem e a cobertura florestal nativa (Mata Atlantica) em vinhedos neotropicais. Para isso, amostramos 19 paisagens de vinhedos no sudeste do Brasil. Essas paisagens cobriam um gradiente de cobertura florestal e heterogeneidade resultante de diferentes usos da terra. Para avaliar a diversidade de aves, consideramos tanto a diversidade taxonomica quanto a diversidade funcional (ou seja, riqueza funcional, uniformidade funcional e divergencia funcional). Para examinar as interacoes potenciais entre as paisagens e as assembleias de aves, empregamos modelos lineares generalizados (GLM). A diversidade taxonomica nao mostrou correlacao com nenhuma metrica da paisagem. Por outro lado, a variacao nas tres metricas da diversidade funcional foi relacionada a heterogeneidade da paisagem. No entanto, em paisagens heterogeneas, essas comunidades podem ser estruturadas por processos de similaridade limitante. Destacamos o impacto negativo da homogeneizacao da paisagem nas funcoes ecologicas desempenhadas por aves em vinhedos, porem nao encontramos efeito significativo na diversidade de especies. Esses resultados podem fornecer um arcabouco valioso para a formulacao de politicas publicas voltadas para encontrar um equilibrio entre producao agricola e conservacao da biodiversidade. This study examines the correlation between landscape heterogeneity and native forest cover on bird functional diversity within Neotropical vineyards in southeastern Brazil. The key findings underscore a positive relationship between landscape heterogeneity and bird functional diversity, underscoring the need of preserving diverse habitats within agroecosystems to strike a balance between food production and biodiversity conservation.image (AU) | |
