中文摘要 | 自1986年1月起至1988年12月止,在臺北植物園的13個植區內調 查赤腹松鼠窩20次,計發現赤腹松鼠所築的窩72個,分別築於10個植區內的 57株樹木上。1986、1987、1988各年內發現的松鼠窩數目分別為27、20 、25。 1988年除12月外,其他每個月均有新窩出現;而新窩之數目以3月、8月、9 月及11月最多。松鼠窩由新築至該窩完全不存在的時間平均為 4.7±3.0月 (N=33)。在所有發現的松鼠窩中,83.3%(60/72)建在雙子葉植物上;15.3%(11/72) 建在單子葉植物的竹類上,1.4%(1/72)建在單子葉植物的非洲海棗上。本調查未 曾在裸子植物上發現松鼠窩。築有松鼠窩的樹種計31種,分屬18科23屬。最 常出現松鼠窩的樹種白千層(Melaleuca leucadendron)和大風子(Hydnocarpus anthelminthica)。築有松鼠窩的 57株樹中,68.4%(39/57)是引進種,31.6%(18/57) 是原生種。三年內重覆出現赤腹松鼠窩的樹木共有8種12株。雙子葉植物上的 赤腹松鼠窩距離地面之平均高度為11.3±2.4m(變域7.2m∼18.7m,N=57),此高 度並分別與樹高、胸高徑呈顯著相關(p<0.01,N=57)。而竹類植物上的松鼠窩距 離地面之平均高度為9.6±1.5m(變域7.7m∼12.2m,N=10),但此高度僅與樹高呈 顯著相關(p<0.01,N=10),與胸高徑之相關不顯著(p>0.01,N=10)。每一區內之 松鼠窩數與該區內的樹木株數相關不顯著(r=0.60,p<0.01,N= 12),卻與該區內 胸高徑大於10cm且樹高大於5m之樹木株數呈顯著相關(r= 0.74,p<0.01, N=12)。 |
英文摘要 | Nests of the Formosan red-bellied tree squirrel (Callosciurus erythraeus) were investigated from January 1986 through December 1988 in Taipei Botanical Garden. Among the 72 nests found on 57 trees, 59.7% (43/72) were built in divisions Ⅱ, Ⅳ, XIV and XVII (Fig.1). Number of nests found in 1986, 1987 and 1988 was 27, 20, and 25, respectively. In 1988, newly built nests were found in every month but December, and peaks of the number of new nests appeared in March, August, October, and November. The average interval that a squirrel nest was found till its disappearance was 4.7±3.0 months (N=33). Among the 72 squirrel nests, 83.3% (60/70) were built on dicotyledon, 15.3% (11/72) on bamboos of monocotyledon. No nest was found on gymnosperm plants. The squirrel nests were found on 31 tree species belonging to 23 genera and 18 families. Fifty six percent of the total nests (40/72) were found on plants of Myrtaceae, Flacourtiaceae, and Gramineae. Twenty seven percent (20/72) of the total nests were found on Melaleuca leucadendron and Hydnocarpus anthelminthica, which were the most frequently selected nest tree species. Among the 57 nest trees, 68.4% (39/57) were introduced species and 31.6% (18/57) were native species. Twelve trees of 8 species were used repeatedly as nest trees. In dicotyledon, nests were built to a height of 7.2m to 18.7m with an average of 11.3±2.4m (N=57), and the height of the nest was significantly correlated with the height and the DBH of the tree, respectively (P<0.01, N=57). In bamboo, nests were built to a height of 7.7m to 12.2m with an average of 9.6 ±1.5m (N=10). The height of the nest was significantly correlated with the height of the bamboo (P<0.01, N=10), but not significantly correlated with the DBH (P<0.01, N=10). The number of nests and the number of trees with height over 5m and DBH over 10cm in each divsion was significantly correlated (r=0.74, P<0.01, N=12). |
