We compared the ability of 33 plant species collected in forest to have their seeds dispersed by the wood red ant Myrmica ruginodis. The elaiosome-bearing seeds (species Chelidonium majus, Colchicum autumnale, Luzula forsteri, Viola reichenbachiana, Luzula multiflora, Melica uniflora) and the small and light caryopses of the grasses (Holcus mollis, Agrostis capillaris, Deschampsia flexuosa, Poa trivialis, Holcus lanatus) are the most efficiently collected by ants. The seed quantity removed by ants is correlated negatively with their length. No significant correlation is found between the rate of seed removal and the frequency of the plants in the field at the scale of the study.
我们比较了在森林中采集的33种植物种子被木红蚁（Myrmica ruginodis）传播的能力。带有油质体的种子（白屈菜、秋水仙、福斯特灯心草、赖兴巴赫堇菜、多花灯心草、单花臭草）以及禾本科植物小而轻的颖果（软绒毛草、细弱剪股颖、弯叶画眉草、普通早熟禾、绒毛草）是最容易被蚂蚁采集的。蚂蚁移除的种子数量与其长度呈负相关。在研究范围内，未发现种子移除率与田间植物出现频率之间存在显著相关性。
