中文摘要 | [摘要] 櫟實是許多野生動物重要的食物資源,其季節性的產量會造成食物資源可得性的變動,而影響野生動物族群的豐富度和時空分布。本研究旨在探討玉山國家公園台灣黑熊(Ursus thibetanus formosanus)的重要棲息地-大分,該地主要樹種青剛櫟(Cyclobalanopsis glauca)的櫟實生產狀況與大型哺乳動物相對豐富度的關係,以期瞭解殼斗科森林對於野生動物的潛在影響。於2006年10月至2009年1月,利用紅外線自動相機監測5種大型哺乳動物(包括台灣黑熊及4種偶蹄類動物)的相對豐富度,發現台灣黑熊的相對豐富度於各年之青剛櫟結果季(10月至次年1月)皆顯著大於非青剛櫟結果季,且青剛櫟季的年間豐富度變動以2008年為最高。台灣水鹿(Rusa unicolor)和野豬(Sus scrofa taivanus)的豐富度亦呈現類似的季節性變動。山羌(Muntiacus reevesi micrurus)的相對豐富度亦呈季節性差異,但在於兩年間的變化趨勢不同;台灣野山羊(Capricornis swinhoei)的相對豐富度在季節間則無顯著差異。本研究顯示大分地區青剛櫟果實提供該地多數大型哺乳動物重要的季節性食物資源,唯對於不同物種的影響不一,推測此除了與物種食性、生態習性及種間交互作用有關之外,亦可能也受到其他食物資源的大尺度分布和豐度變化影響。 |
英文摘要 | ABSTRACT Acorns are a highly nutritious food resource for many wildlife species. The acorn production results in fluctuation of seasonal food availability, and then affects the relative abundance and distribution of wildlife populations. The study objective was to clarify the relationship between the temporally relative abundance of large mammals and the acorn production of ring-cupped oaks (Cyclobalanopsis glauca) in Dafen of Yushan National park, a critical habitat for the endangered Formosan black bear (Ursus thibetanus formosanus). From October 2006 to January 2009, we used infrared camera traps to monitor the relative abundance of five large mammals, including black bears and four ungulate species. The result indicated that the relative abundances of Formosan black bears in acorn seasons (October-next January) were extensively greater than those in non-acorn seasons (Febuary-September) for all studied years. The relative abundance of bears was related to the amount of acorn production, with the highest record in 2008.The relative abundance of sambar deer (Rusa unicolor) and wild boar (Sus scrofa) also showed the similar seasonal patterns like bears. However, the seasonal variation of relative abundance of Formosan Reeve’s muntjacs (Muntiacus reevesi micrurus) differed by years, and no significant difference was found in serows (Capricornis swinhoei). The result indicated that the acorn of ring-cupped oaks in Dafen presented a critical seasonal food resource for most of the large mammals. The effects of acorns on the abundance of the animals may vary by species through their specific ecological requirement, inter-specific interaction, along with the large-scale distribution and abundance of other food resources. |
