Abstract:
UNASSIGNED: Two economies of scale, predator satiation and pollination efficiency, have been proposed to explain the evolutionary mechanisms of mast seeding adopted by some long-lived plants. Plant height is strongly selected by pollination vectors and may also provide economies of scale; however, it remains unknown whether there is a close relationship between adult plant height and mast seeding intensity.
UNASSIGNED: Here, we analyzed mast seeding intensity of 158 plant species to test if adult plant height can select for mast seeding.
UNASSIGNED: We show that mast seeding intensities are higher in taller plant species irrespective of phylogeny, life form, pollination vector, and type of Spermatophytes. We also show that anemophily rather than entomophily selects for taller plant species and higher mast seeding intensities.
UNASSIGNED: The linear correlations and evolutionary links between adult plant height and mast seeding intensity provide evidence that mast seeding could have evolved as an adaptation to taller strategy of perennial plant species.
摘要:
两种规模经济,捕食者的饱腹感和授粉效率,已经被提出来解释一些长寿植物采用的肥大播种的进化机制。植物高度由授粉载体强烈选择,也可能提供规模经济;然而,成年株高与肥大播种强度之间是否存在密切的关系尚不清楚。
这里,我们分析了158种植物的肥大播种强度,以测试成年植物高度是否可以选择肥大播种。
我们表明,无论系统发育如何,较高的植物物种的肥大播种强度较高,生命形式,授粉载体,和精子植物的类型。我们还表明,嗜性而不是嗜性选择更高的植物物种和更高的肥大播种强度。
成年植物高度和肥大播种强度之间的线性相关和进化联系提供了证据,表明肥大播种可能已经进化为适应多年生植物物种的更高策略。
