热带物候的特点是高度的多样性。由于缺乏凉爽的季节来限制生长,物候周期从每年繁殖多次的物种到即使在一个群落中也只在几年内繁殖一次的物种都有所不同。因此,与高纬度地区相比,热带生物物种和群落之间的物候事件的环境线索更加多样化。在气候模式和地理背景不同的地区,全群落的物候模式也不同。随着长期物候数据的积累,特别是长期监测点的树种,这些模式越来越多地被揭示出来。应用于足够长期数据集的分析方法的进步产生了新的见解。长期数据对于了解气候变化如何影响物候模式以及物种相互作用和生物多样性也至关重要。特别重要的是要了解干旱状况的变化,无论是在频率和强度方面,可能会影响植物物候,从而对热带森林社区的级联影响。为了在未来的研究中有效地将物候学研究与热带森林及其生态系统服务的管理联系起来,我们不仅应该继续在现有地点进行观测,而且还应该扩大跨区域的监测地点,包括人类活动改变的生态系统。
Tropical phenology is characterized by its high diversity. Lacking a cool season that restricts growth, phenological cycles vary from species that reproduce multiple times per year to those that reproduce only once in several years even within a community. As such, environmental cues of phenological events are more diverse among species and communities of tropical organisms compared with those in higher latitudes. Community‐wide phenological patterns differ among regions that differ in climate patterns and biogeographical backgrounds. These patterns are increasingly revealed as long‐term phenology data accumulate especially for tree species at long‐term monitoring sites. Advances in analytical methods applied to sufficiently long‐term data sets generate novel insights. Long‐term data are also critically important for understanding how climate changes affect phenological patterns and consequently species interactions and biological diversity. Particularly important is to understand how changes in drought regimes, both in terms of frequency and intensity, may affect plant phenology, and consequently have cascading impacts on tropical forest communities. To effectively link phenology studies and management of tropical forests and their ecosystem services in future studies, we should not only continue observation at existing sites, but also expand monitoring sites across regions, including ecosystems modified by human activities.
