为了满足木材需求，全球范围内纷纷建立林业种植园，这往往导致天然林转变为人工林。人工林可以支持森林生物多样性的自然要素，但了解它们在维持生物多样性中的作用是一个关键问题。我们对 48 项研究进行了荟萃分析，以确定人工林相对于天然林如何影响三个重要鞘翅目类群（即地甲虫、行甲虫和粪甲虫）的物种丰富度和丰度，因为它们在生态系统功能中发挥着重要作用。我们评估了甲虫的反应是否取决于分类群、地理位置、所种植树种的本地或外来特征以及相关的管理特征（即种植园的组成、大小、年龄和连通性）。我们发现，与天然林相比，人工林对鞘翅目物种的丰富度和丰度产生了负面影响。在热带生物群落中种植外来树种的种植园中，负面影响最为严重。在本土种植园中，甲虫的物种丰富度和丰度随着种植园年龄的增加而显着增加，但在外来种植园中则减少。此外，靠近原始森林的小型种植园比远离原始森林的小型种植园具有更高的甲虫物种丰富度和丰度。停止将天然林转变为人工林、促进使用本土树种和延长轮伐期对于林业人工林生物多样性恢复至关重要，并结合强有力的保护战略来保护受威胁的生物多样性和生态系统功能。
Forestry plantations have been established globally to meet timber demands, often leading to the conversion of natural to artificial forests. Forestry plantations may support natural elements of forest biodiversity, but understanding their role in the maintenance of biodiversity is a crucial question. We performed a meta‐analysis of 48 studies to determine how forestry plantations relative to natural forests influence the species richness and abundance of three important coleopteran groups (i.e., ground beetles, rove beetles, and dung beetles), given their essential role in ecosystem functioning. We assessed whether beetle responses depended on taxonomic group, geographical location, native or exotic character of the planted tree species, and associated management characteristics (i.e., composition, size, age, and connectivity of the plantations). We found that forestry plantations negatively affected coleopteran species richness and abundance compared to natural forests. The negative impact was most severe in plantations with exotic tree species and located in tropical biomes. Species richness and abundance of beetles significantly increased with plantation age in native plantations but decreased in exotic ones. Also, small plantations close to native forest had higher beetle species richness and abundance than ones located far away from native forest. Stopping the conversion of natural forests to plantations, promoting the use of native tree species, and lengthening rotations are critical for allowing biodiversity recovery in forestry plantations, combined with a robust conservation strategy to protect threatened biodiversity and ecosystem functioning.
