Seed survival in tropical pioneer trees is unrelated to conspecific distance but linked to fungal infection

Plant demography is heavily influenced by individual survival at local scales, with host-specific natural enemies potentially reducing the survival of seeds and seedlings in high-density patches near conspecific adults, favoring heterospecific recruitment, and ultimately increasing local plant diversity. Enemy pressure should differ between sites directly beneath and away from their hosts’ crowns, between sites where their hosts are abundant versus rare, and among potentially competing plant species. Assessing the potential pathways by which enemies affect diversity at local scales requires coupling experimental approaches that track plant performance with characterization of their enemy communities. We focused on the fate of individuals at the seed stage, a critical demographic bottleneck in the plant life cycle. We tested how seed germination is affected by fungal infection, distance from the adult tree, burial duration, and host tree identity. We conducted a seed burial experiment on..., , # Data from: Seed survival in tropical pioneer trees is unrelated to conspecific distance but linked to fungal infection

We conducted a seed burial experiment to investigate how fungal infection influences seed germination patterns and to examine the effects of distance from the adult tree, burial duration, and host tree identity on seed germination. We buried seeds of four pioneer trees (*Jacaranda copaia, Cecropia insignis, C. peltata, and* C. longipes) below a...,

植物种群动态在很大程度上受局域尺度上的个体存活影响：宿主专一性天敌对同种成年个体附近高密度斑块内的种子和幼苗存活产生潜在抑制作用，进而利于异种幼苗定植，最终提升本地植物多样性。天敌压力在宿主树冠下方与远离树冠的样地之间、宿主丰富与稀少的样地之间，以及不同潜在竞争植物物种之间均存在差异。评估天敌在局域尺度上影响植物多样性的潜在路径，需要将追踪植物表现的实验方法与天敌群落特征表征相结合。

我们聚焦于种子阶段的个体命运——这是植物生活史中关键的种群动态瓶颈。我们测试了真菌侵染、与母树的距离、埋藏时长以及宿主树种身份对种子萌发的影响。我们开展了种子埋藏实验……

我们开展了种子埋藏实验，以探究真菌侵染如何影响种子萌发模式，并检验与母树的距离、埋藏时长以及宿主树种身份对种子萌发的影响。我们在……下埋藏了4种先锋树种的种子：*Jacaranda copaia*、*Cecropia insignis*、*C. peltata*及*C. longipes*……
