中文摘要:
      摘要:四川雉鹑(Tetraophasis szechenyii)是中国特有物种,国家Ⅰ级重点保护野生动物,对其冬季夜栖地选择的了解,有助于理解物种的生存策略,为物种保护提供参考。利用徒步跟踪和无线电遥测的方法,我们于2006年9月到2007年4月在四川省雅江县帕姆岭进行了野外研究。采用卡方检验、配对样本t检验和二元逻辑斯缔回归等方法对数据进行分析。结果发现:(1)四川雉鹑利用鳞皮冷杉(Abies squamata)和大果红杉(Larix potaninii Batalin var. macrocarpa)两种树进行夜栖,卡方检验分析发现四川雉鹑对这两种树种没有明显的选择偏好(χ2 = 0.745,df = 1,P = 0.388);(2)夜栖树的胸径为(25.8 ± 1.3)cm,夜栖枝条的离地高度为(6.3 ± 0.3)m,直径为(3.3 ± 0.1)cm;(3)与对照样地相比,夜栖地生境一般靠近林缘,乔木的平均胸径大、林下盖度小、倒木数量多,夜栖树胸径大、最近乔木胸径大和最近乔木距离远;(4)逻辑斯缔回归分析表明:夜栖树第一枝距地面高为冬季四川雉鹑夜栖地选择的关键因子;倒木数量、平均乔木胸径、最近林缘距离为次关键因子,该模型对夜栖地的预测正确率为80.9%。冬季四川雉鹑选择夜栖地是可能安全、能量和地点转移三个因素综合作用的结果,在不同的环境下,同一物种对环境会有不同的适应策略。
英文摘要:
      Abstract: Buff-throated partridge Tetraophasis szechenyii is an animal unique to China and is listed as the CategoryⅠspecies of nationally protected animals of China. Studying the roosting habitat of buff-throated partridge during the course of winter can help us to understand it’s survival strategies in severe environment, and also can provide very important suggestions in work about conservations. Between September 2006 and April 2007, we carried out field investigation by using pedestrian tracking and radio tracking in Pamuling, Yajiang County, Ganzi autonomous prefecture, Sichuan province, China. We measured 16 environmental factors (Table 1- Habitat factors and explanations). We used Chi-square tests to examine selection differences in tree species of Abies squamata and Larix potaninii Batalin var. macrocarpa, and pared sample t-tests to examine habitat differences between roosting and random quadrats. The results showed that: (1) Buff-throated partridges had no significant difference in selecting two tree species of Abies squamata and Larix potaninii Batalin var. macrocarpa (χ2 = 0.745 , df = 1 , P = 0.388); (2) Roosting trees selected, on average, were 25.8 ± 1.3 cm in diameter at breast height, where buff-throated partridges perched on branches with 6.3 ± 0.3 m in height and 3.3 ± 0.1 cm in diameter at the base; (3) Compared to random quadrats, roosting habitats were closer to the nearest forest edge, with larger trees, opener understory, and more logs, where roosting trees relatively large and farther to other trees with larger diameter at breast height (Table 2-Comparing results on winter habitat factors between roosting and random quadrats of buff-throated partridges). Finally, we used Logistic regressions to find key factors in determining roosting habitat selection. The results revealed that the lowest branch of roosting trees was a primary factor in determining roosting habitat selection, with the secondary factors being number of logs, average diameter at breast height of trees, and the distance to the nearest forest edge (Table 3-Factors selected from Logistic regression and its significance). The model we built had the correct prediction rate of 80.9%. Based on the results, we suggest winter roosting habitat selection by buff-throated partridge as a result of safety, energy saving and site-shifting.
