From March 1996 until February 2000, an study about the phenology of the Tempisque tree [Sideroxylon capiri (A.DC.) Pittier] was made in the Tropical Dry Forest of the Barra Honda National Park (Costa Rica). Ten trees were chosen at random and their phenology was evaluated monthly during the first two years and every two months afterwards. Climatological data were also collected in situ. Trees change their foliage each year during the rainy season or at the beginning of the dry season. In contrast with other native species in forest, soil water deficit is not responsible for foliage change in S. capiri. Some elements that affect the process are photoperiod and herbivores. Unknown physiological mechanisms allow the tree to maintain foliage during the driest months (March and April). Flowering and fruiting may occur every year and in any season, but mostly in the dry season, with variability both among seasons and among individuals.
1996年3月至2000年2月，在巴拉本田国家公园（哥斯达黎加）的热带干旱森林中，对坦皮斯克树（学名：Sideroxylon capiri (A.DC.) Pittier）的物候进行了一项研究。随机挑选了10棵树，在前两年每月评估其物候，之后每两个月评估一次。同时还就地收集了气候数据。树木每年在雨季或旱季开始时更换树叶。与森林中的其他本地物种不同，土壤水分亏缺并不是导致卡皮西德罗木树叶变化的原因。影响这一过程的一些因素是光周期和食草动物。未知的生理机制使这种树能够在最干旱的月份（3月和4月）保持树叶。每年任何季节都可能开花结果，但大多发生在旱季，季节间和个体间存在差异。
