随着气候变化，植物物候发生了巨大的变化，这种变化可能会产生重大而广泛的生态后果。特别令人关切的是热带生物群落，它们是世界上生物多样性最丰富和最危险的区域。然而，与温带植物区系相比，我们对热带植物的物候响应知之甚少，因为热带地区的长期观测数据非常稀少。植物标本馆的标本极大地增加了我们在温带地区的物候学知识，但类似的数据在热带地区却没有得到充分利用，它们的适用性也没有得到广泛的验证。在这里，我们比较物候估计来自实地观测数据（即样地调查）和植物标本馆标本在不同的空间和分类尺度，以确定标本是否可以提供准确的估计生殖时间及其空间variation.Here，我们证明，物候估计从实地观测和植物标本吻合得很好。不到5%的物种表现出显着的差异，从现场观察推断与标本的开花期，无论空间聚集。与基于实地记录的研究相反，植物标本馆标本采集了更大的地理和气候范围，如以前记录的温带植物，并有效地捕捉了不同环境中的物候反应。植物标本被证实是一个至关重要的资源，为关闭差距在我们的物候知识的热带系统。从植物标本记录推断的热带植物生殖物候与野外观测结果广泛一致，这表明它们可以而且应该被用来更广泛地调查整个热带生物群落的物候变化及其相关的环境线索。
Plant phenology has been shifting dramatically in response to climate change, a shift that may have significant and widespread ecological consequences. Of particular concern are tropical biomes, which represent the most biodiverse and imperilled regions of the world. However, compared to temperate floras, we know little about phenological responses of tropical plants because long‐term observational datasets from the tropics are sparse.Herbarium specimens have greatly increased our phenological knowledge in temperate regions, but similar data have been underutilized in the tropics and their suitability for this purpose has not been broadly validated. Here, we compare phenological estimates derived from field observational data (i.e. plot surveys) and herbarium specimens at various spatial and taxonomic scales to determine whether specimens can provide accurate estimations of reproductive timing and its spatial variation.Here, we demonstrate that phenological estimates from field observations and herbarium specimens coincide well. Fewer than 5% of the species exhibited significant differences between flowering periods inferred from field observations versus specimens regardless of spatial aggregation. In contrast to studies based on field records, herbarium specimens sampled much larger geographic and climatic ranges, as has been documented previously for temperate plants, and effectively captured phenological responses across varied environments.Synthesis. Herbarium specimens are verified to be a vital resource for closing the gap in our phenological knowledge of tropical systems. Tropical plant reproductive phenology inferred from herbarium records is widely congruent with field observations, suggesting that they can and should be used to investigate phenological variation and their associated environmental cues more broadly across tropical biomes.
