Seed mix design and floral resources drive multi-trophic interactions in prairie restoration

Ecological restoration often targets plant community recovery, but restoration success may depend on the recovery of a complex web of biotic interactions to maintain biodiversity and promote ecosystem services. Specifically, management that drives resource availability, such as seeding richness and provenance, may alter species interactions across multiple trophic levels. Using experimentally seeded prairies, we examine three key groups – plants, pollinators, and goldenrod crab spiders (Misumena vatia, predators of pollinators) – to understand the effects of species richness and admixture seed sourcing of restoration seed mixtures on multi-trophic interactions.
Working with prairie plants, we experimentally manipulated seed mix richness and the number of seed source regions (single-source region or admixture seed sourcing). In each experimental prairie, we surveyed floral abundance and richness, pollinator visitation, and plant-M. vatia interactions.

生态修复通常以植物群落恢复为核心目标，但修复成效的达成往往依赖于复杂生物相互作用网络的恢复，以此维持生物多样性并推动生态系统服务的实现。具体而言，调控资源可获得性的管理举措（如播种物种丰富度与种子种源选择），可改变多个营养级间的物种相互作用模式。本研究依托实验播种的草原样地，选取植物、传粉者（pollinator）以及秋麒麟蟹蛛（*Misumena vatia*，传粉者的捕食性天敌）三个关键类群，旨在探究修复用种子混合物的物种丰富度与混合种源策略对多营养级相互作用（multi-trophic interactions）的影响。

本研究以草原植物为研究对象，通过实验操控种子混合物的丰富度以及种源区域数量（单一区域种源或混合种源）。在每个实验草原样地中，我们调查了花卉丰度与物种丰富度、传粉者访花行为，以及植物与秋麒麟蟹蛛的相互作用。

高丰富度种子混合物可提升……
