Native plant traits and invasibility of restored communities: Importance of environmental context and trait hierarchies

During community assembly, theory predicts trait convergence among species due to environmental filtering, and trait divergence due to biotic filtering. Learning how traits of non-native species enable them to overcome these filters informs the process of invasion. We manipulated mixtures of native plants in a large restoration project in Southern California that was initially dominated by non-native annual grasses and forbs but was restored to a mixture of native shrubs, grasses, and forbs.  We measured subsequent establishment and performance by three non-native species (Brassica nigra, Salsola tragus, and Sonchus oleraceus) on N- and S-facing slopes to investigate relationships between the abiotic environment, native community composition, and invasibility in the context of trait-driven ecological filters. We then evaluated which community metrics influenced invader performance and tested whether relationships between invader performance and community-weighted traits varied depending..., , , # Reference Information

在群落组装（community assembly）过程中，生态学理论预测：由于环境过滤（environmental filtering）作用，物种种间会出现性状趋同（trait convergence）；而由于生物过滤（biotic filtering）作用，物种种间则会出现性状趋异（trait divergence）。解析外来物种性状如何帮助其突破这些过滤机制，有助于理解生物入侵（invasion）过程。
我们在南加州的一项大型修复（restoration）项目中调控本土植物群落组合：该项目初始区域以外来一年生草本（annual grasses）和杂类草（forbs）占优，后被修复为本土灌木（native shrubs）、草本与杂类草的混合群落。
我们在北向和南向坡地上监测了3种外来物种——黑芥（Brassica nigra）、刺沙蓬（Salsola tragus）和续断菊（Sonchus oleraceus）——的后续定植（establishment）与生长表现（performance），以探究在性状驱动的生态过滤（ecological filters）框架下，非生物环境（abiotic environment）、本土群落组成（native community composition）与群落可入侵性（invasibility）之间的关联。随后我们评估了哪些群落指标（community metrics）会影响入侵物种的生长表现，并检验了入侵物种生长表现与群落加权性状（community-weighted traits）之间的关联是否随...而异。
