  • Shifts in phenotypes derived from the domestication syndromes impact plant performance but may also affect interactions with other species in the community (e.g. mutualists and antagonists). Moreover, plantations often differ from the natural conditions experienced by the wild relatives of cultivated plants, potentially altering the nature of ecological interactions. However, apart from herbivory, little is known about how domestication and cultivation practices (e.g. insecticide application) can modify multiple ecological interactions simultaneously in wild and domesticated plants.
  • In four sites on the Yucatan Peninsula, we compared the diversity of mutualists (e.g. moths) and antagonists (e.g. viruses) in wild and domesticated plants of papaya. For each individual, we recorded floral visitors and rates of visitation at three time periods during the day. We recorded type and percentage of damage by antagonists in three leaves of all individuals. Finally, we explored if plant sex had an effect on the interaction with floral visitors.
  • The main floral visitors were ants and Trigona species, whereas viruses caused the main type of foliar damage. Wild individuals had a higher diversity and visitation rate of floral visitors, and less foliar damage from antagonists. Wild male individuals were more visited, but we observed a similar amount and diversity of damage in both sexes. The time of day did not have an effect on diversity of floral visitors.
  • Together, cultivation practices and domestication appear to have an effect on the reduction in diversity of floral visitors in domesticated papaya, as well as an increase in foliar damage.

野生木瓜和家养木瓜的起源中心互斥和拮抗作用不同

  • 源于驯化综合症的表型变化会影响植物的生长性能,但也可能会影响与社区中其他物种的相互作用(例如互惠生和拮抗剂)。而且,人工林通常不同于栽培植物的野生近缘种所经历的自然条件,有可能改变生态相互作用的性质。然而,除草食性外,关于驯化和栽培实践(例如杀虫剂的施用)如何能够同时改变野生和驯化植物中多种生态相互作用的知识鲜为人知。
  • 在尤卡坦半岛的四个地点,我们比较了木瓜的野生和驯化植物中互惠生(例如飞蛾)和拮抗剂(例如病毒)的多样性。对于每个人,我们记录了一天中三个时段的花卉访客和访客人数。我们记录了所有个体的三片叶子中拮抗剂的伤害类型和百分比。最后,我们探讨了植物性别是否会影响与花卉访客的互动。
  • 花的主要访客是蚂蚁和Trigona物种,而病毒是造成叶面损害的主要类型。野生个体具有较高的多样性和花访者的访视率,并且拮抗剂对叶面的损害较小。野生雄性个体受到更多的访视,但我们观察到两性的破坏程度和多样性相似。一天中的时间对花客的多样性没有影响。
  • 总之,耕作方法和驯化似乎对减少驯化木瓜中花卉访客的多样性以及增加叶面损害具有影响。
