Biotic interactions are expected to be impacted by rising temperatures due to climate change, particularly in climate‐threatened ecosystems such as the tropical montane cloud forest (TMCF). In assisted migration plantings, novel interactions between previously non‐overlapping species may emerge while other interactions may disappear. However, these processes require study. Herbivory is particularly important in tree early stages, and can vary with elevation and plant species traits. We assessed whether leaf herbivory occurs in translocated tree saplings and varies with elevation, and whether herbivory affects sapling growth in six shade‐tolerant TMCF tree species translocated to seven enrichment plantings along an elevation gradient (1,250–2,500 m a.s.l.), including sites located above the reported distributional limit of the species, in eastern Mexico. Given the conservative strategy of the studied plant species, limited damage was expected. Since insects are ectothermic, we expected decreasing herbivory pressure with increased elevation. After 4 years, sapling survival was high (77.9–92.1%). Moderate herbivory was recorded in all species and at all sites (1.0–6.6%), with no effect on growth in any of the species. Herbivory decreased with elevation in three species and was unaffected in the other three. The results indicate that plant‐herbivore interactions can continue at new locations; however, the contribution of generalist and specialist insect herbivores requires further study. The reduced herbivory at higher elevation in some species supports the expected trend, which could represent an advantage for upward assisted migration of endangered TMCF tree species in restoration plantings to mitigate climate change effects.

植物与草食动物之间的相互作用在辅助移栽中是否持续存在？

由于气候变化，尤其是在受气候威胁的生态系统（如热带山地云雾森林（TMCF））中，生物相互作用预计会受到温度升高的影响。在辅助移栽中，以前不重叠的物种之间可能会出现新的相互作用，而其他相互作用可能会消失。但是，这些过程需要研究。在树木的早期阶段，食草特别重要，并且可以随海拔和植物物种性状而变化。我们评估了叶食草是否发生在易位树苗中并随海拔变化而变化，以及食草是否影响了六种耐荫的TMCF树种的树苗生长，这些树荫植物沿海拔梯度（1,250–2,500 m asl）（包括位于上方的站点）转移至七个富集种植报告的物种分布极限，在墨西哥东部。考虑到所研究植物物种的保守策略，预计损害程度有限。由于昆虫是放热的，因此我们预计草食动物的压力会随着海拔的升高而降低。4年后，幼树存活率很高（77.9–92.1％）。在所有物种和所有地点均记录有中度草食动物（1.0-6.6％），对任何物种的生长均无影响。在三个物种中，草食性随海拔升高而降低，而在其他三个物种中不受影响。结果表明，植物—草食动物之间的相互作用可以在新的位置继续进行。然而，通才昆虫和专门昆虫食草动物的贡献有待进一步研究。在某些物种中，海拔较高的草食动物减少，支持了预期的趋势，
