Abstract

Aim

The enemy release hypothesis states that the invasion success of non-native species is partly due to their escape from natural enemies, e.g., herbivores. Large-scale studies of herbivory using multiple species across multiple sites are needed to test the generality of herbivory release in non-native plants.

Location

Europe.

Methods

We carried out leaf-herbivory surveys from 2007 to 2021 in 15 botanical gardens ranging in latitude from 47°N (Switzerland) to 63°N (Norway) to investigate how herbivory levels differed between (i) native and non-native species, and (ii) native and non-naturalised or naturalised species.

Results

Overall, we found that herbivory levels were lower on non-native than native species. In addition, we found that non-naturalised plants suffered less herbivory than natives and that naturalised plants showed similar levels of herbivory to native plants.

Main Conclusions

We find broad support for lower herbivory of non-native plant species compared to natives. However, the stronger reduction in herbivory for non-naturalised plants suggests that herbivore release may be transient and less pronounced for naturalised non-native species that have become abundant and integrated into resident communities. This has implications for the management of naturalised non-native plants, which are performing well in their non-native ranges despite suffering comparable herbivory levels to native species.

在欧洲植物园中，非本地、非归化的植物比本地植物遭受的食草性更少

目的敌人释放假说认为，非本地物种的入侵成功部分是由于它们逃离了天敌，例如食草动物。为了测试非本地植物中草食释放的普遍性，需要在多个地点进行多物种的大规模草食研究。位置欧洲。方法2007年至2021年，我们在纬度为47°N（瑞士）至63°N（挪威）的15个植物园开展了叶片-草食调查，以研究(i)本地和非本地物种，（ii）本地和非归化或归化物种之间的草食水平差异。结果总体而言，我们发现非本地物种的草食水平低于本地物种。此外，我们发现非归化植物比本地植物遭受更少的食草性，而归化植物的食草性水平与本地植物相似。结论：与本地植物相比，非本地植物的食草性较低。然而，非归化植物的食草性减少更明显，这表明对于已经丰富并融入居民群落的归化非本地物种来说，食草性释放可能是短暂的，不那么明显。这对自然化的非本地植物的管理有影响，这些植物在其非本地范围内表现良好，尽管它们的食草性水平与本地物种相当。

期刊介绍： Diversity and Distributions is a journal of conservation biogeography. We publish papers that deal with the application of biogeographical principles, theories, and analyses (being those concerned with the distributional dynamics of taxa and assemblages) to problems concerning the conservation of biodiversity. We no longer consider papers the sole aim of which is to describe or analyze patterns of biodiversity or to elucidate processes that generate biodiversity.
