Supporting data and code for Mendes et al. 202X Evidence of a European seed dispersal crisis<b>Abstract</b>Seed dispersal is crucial for ecosystem persistence, especially in fragmented landscapes, such as those common in Europe. Ongoing defaunation might compromise effective seed dispersal, but the conservation status of pairwise interactions remains unknown. With a literature review, we reconstructed the first European-wide seed dispersal network and evaluated interactions’ conservation status by assessing each interacting partner’s IUCN conservation status and population trends. We found that a third of the disperser species and interactions face potential extinction and that 30% of the plant species have most of their dispersers threatened or declining. While our study clearly reveals a developing seed dispersal crisis across all European biomes, it also highlights large knowledge gaps regarding the dispersers of most European zoochorous plants, as well as their conservation status, urging further scrutiny and action to conserve the seed dispersal service.

**摘要**
种子传播对生态系统存续至关重要，在欧洲常见的破碎化景观中尤为如此。持续发生的动物区系衰退可能会削弱有效种子传播，但两两物种间互作的保护现状仍不明朗。本研究通过文献综述，构建了首个覆盖全欧洲的种子传播互作网络，并通过评估每对互作物种的世界自然保护联盟（IUCN）保护等级与种群趋势，评价了这些互作的保护现状。研究发现，三分之一的传播者物种及互作关系面临潜在灭绝风险，且30%的植物物种的多数传播者正受到威胁或种群数量下降。尽管本研究清晰揭示了欧洲所有生物群区正逐渐出现种子传播危机，但同时也凸显出当前存在大量知识空白：多数欧洲动物传播植物的传播者物种及其保护现状尚未明确，亟需开展进一步研究与行动以保护种子传播生态服务功能。
