中文摘要 | 針對訪客出現與否及數量對研究人員觀察的臺灣山羌(Muntiacus reevesi micrurus)個體或吠叫數量之影響,自1994年7月至1995年12月及1997年1月、3及4月,在玉山國家公園之瓦拉米地區進行調查。研究者在兩條調查路線上以定速緩慢步行,記錄觀察到的山羌個體、叫聲及人類數量。結果顯示,累計總訪客人次為690人次。調查期間內共目擊山羌106隻次,平均每天目擊1.08±1.37隻次,無訪客時平均每天目擊1.45±1.61隻次,有人員干擾時平均每天目擊0.83±1.10隻次(n=48隻次)。有訪客出現時,當日訪客人數在15人以下時(含15人)目擊山羌數量平均為0.98隻次/天,而在15人以上時則減為0.36隻次/天;在無訪客與訪客人數之多寡三種情況下,無訪客與訪客為15人以上時,兩種情況的目擊隻次之間有顯著差異(ANOVA,p<0.05)。66次之目擊記錄顯示,研究人員與目擊山羌之間的距離自2m至50m不等,平均為18.48m,訪客數量與當天各次目擊山羌之平均距離無顯著關係。記錄山羌之叫聲有1013次,平均每天10.34±5.75次,在叫聲記錄中近距叫聲(與步道距離<50m)所佔之比例為15%。有無訪客出現對當日記錄叫聲次數並無影響,但在無訪客時單日近距叫聲所佔比例為21%,有訪客時為11%,有明顯差別(t-test,p<0.05),單日內近距叫聲所佔比例有隨著訪客人數增加而減少之趨勢(迴歸分析,p<0.05)。 |
英文摘要 | We studied the impact of visitors on muntjac (Muntiacus reevesi micrurus) from July 1994 to December 1995 and January, March, and April in 1997 at Walami area in Yushan National Park, Taiwan. Number of visitors, muntjac numbers, and barking were recorded on two selected routes. The result showed that 690 visitors and 106 muntjac were recorded in the study period. The average daily sighting was 1.08±1.37. The average sighting frequency was 0.83 muntjac per day when the trail had visitors. The average sighting was 0.98 muntjac per day when the visitor number was below 15, while the sighting number was 0.36 per day when the visitor number was over 15. There was a significant difference of sighting (ANOVA,p<0.05) between days without visitors (1.45±1.61) and days with visitors over 15. From 66 sighting records, the average distance between researchers and muntjac was 18.48m (2-50m). Number of visitors present in any given day had no significant effect on sighting distance. We recorded 1013 muntjac barking. The average daily barking was 10.34±5.75. Among them 15% was classified as the short distance barking (<50m). The presence or absence of visitors had no influence on the frequency of muntjac barking. However, it had a significant influence (t-test, p<0.05) on the frequency of short distance barking (21% without visitors and 11% with visitors). And there was also a negative correlation (p<0.05) between visitor number and short distance barking. |
