Flowering and fruiting phenology can have large impacts on a plant's reproductive success. In many plant species, these phenological events are controlled by seasonal climatic cues, resulting in one-year reproductive cycles. However, parts of SE Asian tropical forests have an aseasonal climate with irregular fluctuations. This database comprises phenology records collected from 1993 to 2011 at the community level in an aseasonal lowland dipterocarp forest of the Lambir Hills National Park in Borneo. Observations were made every two weeks at three sites: The Canopy Biology Plot (CBP) with tree towers and walkways, the Operation Raleigh Tower (ORT) area with a tree tower for tourist attraction, and the Crane Plot located between the CBP and ORT, where plants were monitored from terraces on a canopy crane installed in 2000. The dataset includes in total 172,521 records of 450, 118, and 51 plants in CBP, Crane Plot, and ORT, respectively, representing 303 species. The number of individuals per species ranges from 1 to 21, and 64.9% are represented by only one. The plants in the censuses were mostly trees but also included lianas and epiphytes. The data have been used to study the causes and consequences of synchronized flowering and fruiting at the community level, a phenomenon unique to the region. Previous studies have shown that this synchronization is synergistically driven by cool air temperature and drought. Irregular flowering and fruiting have significant impacts on flower visitors, frugivores, forest material cycling, and plant regeneration. The dataset can also be used for comparing the phenology of the same species or group among forests and regions and exploring its association with climates. One major concern regarding tropical forests in the area is the effects of climate change on this community-wide masting regime, which could disrupt forest regeneration and ecosystem processes. The dataset could be an important source of information for conservation efforts aimed at protecting these amazingly diverse forest ecosystems. This dataset can be freely used for non-commercial purposes. Users of these data should cite this data paper in any publications resulting from its use and acknowledge the Forest Department Sarawak and Sarawak Forestry Corporation.
开花和结果物候对植物的繁殖成功有着重大影响。在许多植物物种中，这些物候事件受季节性气候线索控制，形成一年的繁殖周期。然而，东南亚部分热带森林气候无季节性，波动不规则。该数据库包含1993年至2011年在婆罗洲兰比尔山国家公园无季节性低地龙脑香林社区层面收集的物候记录。在三个地点每两周进行一次观测：设有树冠塔和步道的树冠生物学样地（CBP）、有供游客参观的树冠塔的罗利行动塔（ORT）区域，以及位于CBP和ORT之间的起重机样地，在那里通过2000年安装的树冠起重机平台对植物进行监测。该数据集分别包含CBP、起重机样地和ORT中450种、118种和51种植物的总计172,521条记录，代表303个物种。每个物种的个体数量从1到21不等，64.9%仅由一个个体代表。普查中的植物大多是树木，但也包括藤本植物和附生植物。这些数据已被用于研究社区层面同步开花和结果的原因及后果，这是该地区特有的现象。先前的研究表明，这种同步受冷空气温度和干旱协同驱动。不规则的开花和结果对访花者、食果动物、森林物质循环和植物更新有重大影响。该数据集还可用于比较不同森林和地区同一物种或类群的物候，并探索其与气候的关联。该地区热带森林的一个主要担忧是气候变化对这种全社区大规模结实机制的影响，这可能扰乱森林更新和生态系统过程。该数据集可能是旨在保护这些极其多样的森林生态系统的保护工作的重要信息来源。该数据集可免费用于非商业目的。使用这些数据的用户应在因使用该数据集而产生的任何出版物中引用本数据论文，并感谢沙捞越森林部门和沙捞越林业公司。
