中文摘要 | 溫度及體型大小在生態學代謝理論 (Metabolic Theory of Ecology) 中是決定生 物代謝速率的基本因素,這些因素對個體的生長發育和繁殖、族群增長、物種多樣性, 甚至對生態系過程的影響很是重要。本研究在武陵地區週期性採集臺灣雲杉 (Picea morrisonicola) 上鳳梨形蟲癭為時三年,為了解溫度對鳳梨形蟲癭內球蚜發育的影 響,利用武陵氣象資料估算出此球蚜的癭蚜發育期的積溫,來進行積溫及年份對癭蚜 發育的影響之迴歸分析,最佳模型結果為年份變數無影響,積溫 (x) 與癭蚜體長 (y) 為正相關,迴歸方程式為 y = -0.25368 + 0.00078x (p = 0.002, R2 = 0.8774)。然而積 溫+年份的複迴歸方程式亦成立 (p = 0.0083, R2 = 0.8874),2009 年的累積度日數增 加且癭蚜體長較 2007 年為大,故推測氣溫若上升則可能有利 Adelges sp.癭蚜的發育 及繁殖。因此,森林及自然資源管理者應不容忽視本土臺灣雲杉受到球蚜的潛在危害。 |
英文摘要 | The Metabolic Theory of Ecology states that temperature and body size are the basic determinants of an organism’s metabolic rate. The effect of these determinants on individual development and fecundity, population growth, species diversity, and even on the ecosystem are important. In this study, we periodically collected pineapple galls on Taiwan spruce, Picea morrisonicola, during 2007 to 2009. In order to elucidate the effect of temperature on the development of adelgid in pineapple gall, we estimated the accumulated temperature of the gallicola developmental period using three years of meteorological data for Wuling. The accumulated temperature and the particular year are the two variables that taken into consideration in multiple regression analysis to determine their effect on the development of gallicola. The best model revealed that the year variable had no effect, and that body length was positively correlated with the accumulated temperature (y = -0.25368 + 0.00078x, p = 0.002, R2 = 0.8774). Nevertheless, the accumulated temperature + particular year model was also significant (p = 0.0083, R2 = 0.8874), and the gallicola size was larger in 2009, due to a higher accumulated degree-day. We predict that a moderately rising temperature will be advantageous to the gallicola of Adelges sp. in both development and fecundity. Therefore, forest and natural resource managers should be aware that endemic Taiwan spruce will potentially face a growing threat by the adelgid. |
