- Forest canopies provide the initial physical and biological framework to secondary, dependent species, such as parasitic plants. In a Mediterranean pine forest, we have taxonomically and functionally characterised the entire arthropod community that interacts with mistletoe during its flowering period.
- We hypothesise that a secondary foundation species such as mistletoe enhances the arthropod diversity and abundance, fostering novel plant–animal interactions in the canopy. Our results clearly show contrasting guilds of herbivores (highly specialised) and floral visitors (highly generalist) with markedly different taxonomic and ecological profiles, the latter determining the fruit set of the mistletoe.
- By acting as a secondary foundation species, mistletoe, during flowering, increases the diversity and abundance of newcomers in the pine canopy. New species attracted to the canopy include a specialised herbivore, Cacopsylla visci, and a diverse guild of floral visitors, including the orders Hymenoptera, Diptera, Hemiptera, and Lepidoptera.
- In conclusion, mistletoe creates conditions that support the co‐occurrence of functionally distinct organisms in the canopies, fostering pine forest biodiversity and complexity of ecological interactions.

次生基础物种在森林冠层中促进新型的植物-动物相互作用：槲寄生的证据
- 森林冠层为诸如寄生植物之类的次要依赖物种提供了初始的物理和生物学框架。在地中海松树林中，我们在分类和功能上对整个节肢动物群落进行了分类，该节肢动物在开花期与槲寄生相互作用。
- 我们假设诸如槲寄生的次生基础物种增强了节肢动物的多样性和丰度，促进了冠层中新型的植物-动物相互作用。我们的结果清楚地表明，草食动物（高度专业化）和花卉访客（高度通才）的行业协会具有明显不同的分类和生态特征，后者决定了槲寄生的果实。
- 槲寄生通过作为次生基础物种，在开花过程中增加了松树冠中新来者的多样性和丰富性。被冠层吸引的新物种包括专门的食草动物，虎尾草和各种各样的花卉访客协会，包括膜翅目，双翅目，半翅目和鳞翅目。
- 总之，槲寄生创造了支持冠层中功能不同的生物共生的条件，从而促进了松树林的生物多样性和生态相互作用的复杂性。
