Thus although new research into large vertebrates has increased in recent years, acquiring the data on population numbers, precise distribution and natural history which are needed in order to define conservation strategies, still depends on what Li Ling-ling describes as "chance accumulation."
因此即使大型脊椎動物的研究，近年來確有增加，但擬訂保護策略所需的數量、明確分佈、相關生態習性等資料，都只能依賴李玲玲形容的「逢機累積」。
