Measuring habitat specialisation is pivotal for predicting species extinctions and for understanding consequences on ecosystem functioning. Here, we sampled pollinator and natural enemy communities in all major habitat types occurring across multiple agricultural landscapes and used species–habitat networks to determine how habitat specialisation changed along gradients in landscape composition and configuration. Although it is well known that landscape simplification often causes the replacement of specialists with generalists, our study provided evidence for intraspecific variation in habitat specialisation, highlighting how a large number of arthropod species adapted their way of selecting habitat resources depending on the landscape structure. Groups with higher diet specialisation and limited foraging flexibility appeared to have a reduced ability to respond to landscape changes, indicating that some arthropod taxa are better able than others to adapt to an increasingly broad set of resources and persist in highly impacted landscapes.

物种栖息地网络阐明了景观对天敌和传粉媒介栖息地专业化的影响

测量生境专业化对于预测物种灭绝和了解对生态系统功能的影响至关重要。在这里，我们对跨越多种农业景观的所有主要生境类型中的传粉媒介和天敌群落进行了采样，并使用了物种-栖息地网络来确定生境专业化如何随景观组成和配置的梯度变化。尽管众所周知，景观的简化通常会导致通才替代专家，但我们的研究为栖息地专业化的种内差异提供了证据，强调了许多节肢动物物种如何根据景观结构来适应其选择栖息地资源的方式。
