近日，德国哥廷根大学Gustavo B. Paterno及其小组的最新研究显示，多样化和更大的树岛促进了油棕景观中原生树木的多样性。该研究于2024年11月15日发表于国际一流学术期刊《科学》杂志上。

据悉，在单一作物为主的景观中，恢复生物多样性是一个优先事项，但有效的恢复策略尚未确定。

在这项研究中，研究人员通过实验测试了被动和主动策略，以恢复油棕景观中52个树岛内木本植物的分类、系统发育和功能多样性。大的树岛和较高的初始植物多样性促进了多样性的恢复，尤其是景观水平上的功能多样性。

研究结果表明，在局部尺度上，更大的初始种植多样性会带来更大的当地补充多样性，从而克服了高度修饰景观中自然补充的局限性。研究结果强调，建立大型和多样化的树岛，对于保护油棕景观中的珍稀、特有和森林相关物种至关重要。

Abstract: In monoculture-dominated landscapes, recovering biodiversity is a priority, but effective restoration strategies have yet to be identified. In this study, we experimentally tested passive and active restoration strategies to recover taxonomic, phylogenetic, and functional diversity of woody plants within 52 tree islands established in an oil palm landscape. Large tree islands and higher initial planted diversity catalyzed diversity recovery, particularly functional diversity at the landscape level. At the local scale, results demonstrated that greater initial planting diversity begets greater diversity of native recruits, overcoming limitations of natural recruitment in highly modified landscapes. Establishing large and diverse tree islands is crucial for safeguarding rare, endemic, and forest-associated species in oil palm landscapes.
