Data for: Organic management and landscape heterogeneity combine to sustain multifunctional bird communities in European vineyards

Conserving functionally diverse bird communities in European farmland is becoming critical, with no exception for regions of wine production. Management intensification combined with the loss of semi-natural habitats in wine-growing landscapes has led to a long-term decline in birds of conservation concern, but also in once common insectivores and seed eaters. These declines are expected to threaten key ecological functions provided by vineyard birds, such as pest or weed control, but also their cultural significance.
We analyzed how organic management and landscape heterogeneity affected taxonomic and functional diversity of 334 bird communities from 12 regions of the three main wine-producing European countries (France, Italy and Spain). We further modelled the responses of community-level metrics measuring mean habitat specialization and bird song attractiveness to humans, as well as cumulative abundances of functional insectivores, seed and grape eaters to account for individua...

保护欧洲农田内功能多样的鸟类群落愈发关键，葡萄酒产区亦无例外。葡萄酒种植景观中的集约化经营与半自然生境（semi-natural habitats）丧失，已导致需保育关注鸟类（birds of conservation concern）的种群长期衰退，同时也使曾经常见的食虫鸟类与食籽鸟类数量显著下降。此类种群衰退预计将威胁葡萄园鸟类所提供的关键生态功能——例如害虫防控与杂草防治，同时亦会损害其文化价值。
本研究分析了欧洲三大葡萄酒生产国（法国、意大利与西班牙）的12个区域内的334个鸟类群落，探究有机管理（organic management）与景观异质性（landscape heterogeneity）对其分类多样性与功能多样性（taxonomic and functional diversity）的影响。我们进一步构建模型，分析群落水平指标的响应特征：这些指标涵盖平均生境特化程度、鸟类鸣唱对人类的吸引力，以及功能性食虫鸟类、食籽鸟类与食葡萄鸟类的累积丰度，以阐释个体……
