Some animals can move fast to adjust to a quickly changing climate. Plants, being less mobile, rely on means such as seed dispersal (传播) by animals, wind or water to move to new areas, but this redistribution typically occurs within one kilometer of the original plant. Writing in Nature, Juan P. González-Varo sheds light on the potential capacity of migratory (迁徙的) birds to aid seed dispersal. González-Varo and colleagues report how plants might be able to keep pace with rapid climate change through the help of migrating birds. They analyzed an impressive data set of 949 different seed-dispersal interactions between bird and plant communities, together with data on entire fruiting times and migratory patterns of birds across Europe. The authors hypothesized (假定) that the direction of seed migration depends on how the plants interact with migratory birds, the frequency of these interactions or the number of bird species that might transport seeds from each plant species. Perhaps the most striking feature of these inferred seed movements is the observation that 35 percent of plant species across European communities, which are closely related on the phylogenetic tree (进化树谱), might benefit from long-distance dispersal by the northward journey of migratory birds. This particular subset (小组) of plants tends to fruit over a long period of time, or has fruits that persist over the winter. This means that the ability of plants to keep up with climate change could be shaped by their evolutionary history – implying that future plant communities in the Northern Hemisphere (半球) will probably come from plant species that are phylogenetically closely related and that have migrated from the south. This study provides a great example of how migratory
