我们观察到野生爪哇鹿（Trachypithecus auratus）和鲁萨鹿（鲁萨timorensis）之间的种间关联。在这种关联中，前者丢弃植物物品，后者随后消耗（收集）。我们调查了这种联系是否对居住在季节变化剧烈的热带地区的鹿有利。2011年至2013年，我们在印度尼西亚Pangandaran自然保护区进行了实地调查。我们观察到248拾穗事件，这些拾穗事件的总持续时间（60.1小时）对应于约4%的lutung观察时间。鹿吃了鹿通掉落的39件物品，这些物品属于28种植物，包括树叶、水果和鲜花。在降雨量低和草地斑块中草本植物很少的月份，更频繁地发生了拾取事件。收集的食物明显比未收集的食物重。本研究结果显示，鹿洞鹿群在食物资源缺乏的季节，可改善鹿的营养状况，对鹿是有益的。
We observed an interspecies association between wild Javan lutungs (Trachypithecus auratus) and rusa deer (Rusa timorensis). In this association, the former drops plant items that the latter subsequently consumes (glean). We investigated whether the association is beneficial for deer that inhabit tropical regions characterized by drastic seasonal changes. Between 2011 and 2013, we conducted field surveys in the Pangandaran Nature Reserve, Indonesia. We observed 248 gleaning events; the total duration (60.1 h) of these gleaning events corresponded to approximately 4% of the lutung observation time. Deer consumed 39 items dropped by lutungs; these items belonged to 28 plant species and included leaves, fruits, and flowers. Gleaning events occurred more frequently during months when rainfall was low and few herbaceous plants grew in grassland patches. Gleaned foods were significantly heavier than non-gleaned foods. Our findings imply that the lutung—deer association is beneficial to deer, by improving nutritional condition during seasons with low food resources.
