中国成熟森林的广泛破坏导致了大规模的生态退化，近几十年来，通过大力促进人工林和保护次生林生态系统来抵消这种退化。由此产生的森林对生物多样性保护的价值普遍未知，特别是与履行重要生态系统服务的高度多样化的无脊椎类群有关。我们的目标是解决这一知识差距，基于几何蛾的多样性建立中国北方东陵山次生林的保护价值。几何蛾是一种物种丰富的夜间传粉昆虫，也通过毛虫的食草性影响植物的组合。结果表明，长白山自然保护区次生林的几何蛾类群在物种丰富度和系统发育多样性上相似，但其物种组成与长白山自然保护区中国仅存的温带成熟森林的几何蛾类群明显不同。这些位点之间的物种重叠约为30%，物种没有根据位点形成单独的系统发育集群。东陵山不同森林类型的物种组合分化明显；这种模式在长白山没有发现。研究结果表明，中国北方自然再生次生林为物种丰富、遗传多样性丰富的几何蛾提供了适宜的栖息地，突出了这些森林在更广泛的景观保护和生态系统功能提供方面的潜在重要性。
The widespread destruction of mature forests in China has led to massive ecological degradation, counteracted in recent decades by substantial efforts to promote forest plantations and protect secondary forest ecosystems. The value of the resulting forests for biodiversity conservation is widely unknown, particularly in relation to highly diverse invertebrate taxa that fulfil important ecosystem services. We aimed to address this knowledge gap, establishing the conservation value of secondary forests on Dongling Mountain, North China based on the diversity of geometrid moths – a species-rich family of nocturnal pollinators that also influences plant assemblages through caterpillar herbivory. Results showed that secondary forests harboured geometrid moth assemblages similar in species richness and phylogenetic diversity, but with a species composition distinctly different to assemblages in one of China’s last remaining mature temperate forests in the Changbaishan Nature Reserve. Species overlap between these sites was about 30%, and species did not form separate phylogenetic clusters according to site. Species assemblages at Dongling Mountain were strongly differentiated according to forest type; a pattern not found at Changbaishan. Our results indicate that protected naturally regenerated secondary forests in northern China provide suitable habitats for species-rich and genetically diverse geometrid moth assemblages, highlighting the potential importance of these forests for conservation and ecosystem function provision across the wider landscape.
