果类植物和食果鸟类是相互影响的。在动物传播中，食果鸟类食用水果，随后传播种子。由此可见，水果的特性会进化到让鸟类更容易食用水果。然而，一方的利益并不总是意味着另一方的利益。结果植物和食果鸟类在营养成分、停留时间和粪便颗粒中种子数量方面存在一些冲突。种子在肠道中的保留时间特别有趣。较长的保留时间通过增加种子传播距离直接使植物受益，但可能通过减少鸟类的消费而产生间接成本。要了解种子传播者在结果植物繁殖成功中的确切作用，我们应该更多地关注结果植物和食果鸟类之间可能发生的冲突。
Fruiting plants and frugivorous birds are known to interact. In endozoochory, frugivorous birds consume fruits and subsequently disperse seeds. It follows that fruit characteristics would have evolved to allow birds to consume fruits easily. However, one's benefit does not always mean the other's. There are several conflicts between fruiting plants and frugivorous birds in terms of nutrient content, retention time and number of seeds in a fecal pellet. Retention time of seeds in guts is particularly interesting. Longer retention time benefits plants directly by increasing seed dispersal distance but may involve indirect costs through birds' preference by reducing their consumption. To understand the exact role of seed dispersers in the reproductive success of fruiting plants, we should pay more attention to the possible conflicts between fruiting plants and frugivorous birds.
