Abstract Agricultural expansion changes wildlife communities. Some species adapt to working lands, increasing their relative abundance in these modified landscapes, and this may result in spillover effects for communities in adjacent wildlands. These effects remain largely undocumented, even though they can affect biodiversity conservation. We conducted bird surveys at 130 Mediterranean-climate oak woodland locations that exist across a gradient of nearby vineyard development. We used zero inflated Poisson (ZIP) N-mixture models to analyze the relationships among detected bird species, local vegetation, and surrounding vineyard land cover. We used joint species distribution modeling (JSDM) to measure species co-occurrence patterns and account for the influence of the surrounding agricultural land in order to explore indirect effects between bird communities associated with vineyard expansion and oak woodland remnants. We identified 10 species as agricultural adapters based on their positive associated with vineyard land cover. Co-occurrence patterns suggested that i) agricultural adapter species may negatively interact with certain species associated with oak woodlands in adjacent wildlands, so competition with agricultural adapters may be an important driver of biotic homogenization of the community, and (ii) some positive species interactions were detected, especially among insectivore foliage gleaners, which may be facilitated by niche partitioning. Continued examination of spillover effects from agricultural land into adjacent natural areas is warranted in light of global species declines and biotic homogenization.

来自葡萄园景观的农业适配器影响原生橡树林地鸟类

摘要 农业扩张改变了野生动物群落。一些物种适应工作土地，增加了它们在这些改良景观中的相对丰度，这可能会对邻近荒地的社区产生溢出效应。尽管这些影响会影响生物多样性保护，但它们在很大程度上仍未被记录在案。我们在 130 个地中海气候橡树林地地点进行了鸟类调查，这些地点存在于附近葡萄园开发的梯度上。我们使用零膨胀泊松 (ZIP) N 混合物模型来分析检测到的鸟类、当地植被和周围葡萄园土地覆盖之间的关系。我们使用联合物种分布模型 (JSDM) 来测量物种共生模式并考虑周围农田的影响，以探索与葡萄园扩张和橡树林地残余相关的鸟类群落之间的间接影响。我们根据其与葡萄园土地覆盖的正相关性确定了 10 个物种作为农业适配器。共生模式表明 i) 农业适应物种可能与邻近荒地橡树林地相关的某些物种产生负面相互作用，因此与农业适应物种的竞争可能是群落生物同质化的重要驱动因素，以及 (ii) 一些积极的物种相互作用被检测到，尤其是在食虫性树叶收集者中，这可能是通过生态位分区来促进的。
