Data from: Museum specimens provide novel insights into changing plant-herbivore interactions

<b>Abstract</b><br/>Mounting evidence shows that species interactions may mediate how individual species respond to climate change. However, long-term anthropogenic effects on species interactions are poorly characterized due to a lack of data. Insect herbivory is a major ecological process that represents the interaction between insect herbivores and their host plants, but historical data on insect damage to plants is particularly sparse. Here, we suggest that museum collections of insects and plants can fill key gaps in our knowledge on changing trophic interactions, including proximate mechanisms and the net outcomes of multiple global change drivers across diverse insect herbivore-plant associations. We outline theory on how global change may affect herbivores and their host plants and highlight the unique data that could be extracted from museum specimens to explore their shifting interactions. We aim to provide a framework for using museum specimens to explore how some of the most diverse co-evolved relationships are responding to climate and land use change.

**摘要**
越来越多的证据表明，物种间相互作用可调节单个物种对气候变化的响应模式。然而，由于数据匮乏，人类活动对物种相互作用的长期影响尚未得到充分研究与刻画。昆虫植食作用是一类核心生态过程，反映了昆虫植食者与其寄主植物之间的相互关系，但有关昆虫对植物造成危害的历史数据尤为稀缺。本研究提出，昆虫与植物的馆藏标本可填补我们在营养相互作用动态研究中的关键空白，包括解析多样昆虫-植物植食关联中多种全球变化驱动因子的作用近因机制与最终净效应。我们梳理了全球变化影响植食者及其寄主植物的相关理论，并强调可从馆藏标本中获取独特数据，以探究二者相互作用的动态变化。本研究旨在构建研究框架，借助馆藏标本探究全球最为多样的协同进化关系之一如何响应气候变化与土地利用变化。
