研究發現，哥斯達黎加雲霧林中的多種哺乳動物會利用絞殺榕（𝘍𝘪𝘤𝘶𝘴 𝘵𝘶𝘦𝘳𝘤𝘬𝘩𝘦𝘪𝘮𝘪𝘪）的特定樹枝交界處作為公共廁所。絞殺榕獨特的生長形態形成許多平坦的高空平台；研究人員以紅外線相機記錄到17種不同的哺乳動物會到訪這些平台排便，並透過氣味交換社交訊息。
Researchers found that various cloud-forest mammals in Costa Rica use specific tree junctions of the strangler fig (𝘍𝘪𝘤𝘶𝘴 𝘵𝘶𝘦𝘳𝘤𝘬𝘩𝘦𝘪𝘮𝘪𝘪) as shared latrines. The strangler fig’s unique growth form creates flat platforms high in the canopy. Using camera traps, researchers recorded 17 different mammal species visiting these sites to defecate and to exchange social information via scent.
