我们研究了林分、景观和空间变量对日本中部长野县山区落叶林和落叶松 (Larix leptolepis (Sieb & Zucc.) Gord.) 人工林鸟类群落的影响。我们在 97 个地点使用了样地横断面方法：在落叶林中，2003 年冬季有 33 个地点，2004 年繁殖季节增加了 18 个地点；在落叶松人工林中，2004 年冬季有 32 个地点，2005 年繁殖季节增加了 14 个地点。使用部分冗余分析和部分回归分析来探讨鸟类与环境的关系。我们使用从邻近矩阵的主坐标导出的空间变量作为解释变量来检测鸟类群落的非随机空间结构。鸟类群落的变化主要由两种森林类型的林分和空间变量来解释，而景观变量的影响很小。在种植园中，两个季节的重要林分变量包括林分高度、海拔和...
We examined the effects of stand, landscape, and spatial variables on bird communities in deciduous forests and Japanese larch (Larix leptolepis (Sieb & Zucc.) Gord.) plantations in a montane region of Nagano Prefecture, central Japan. We used plot-transect methods at 97 sites: 33 in winter 2003 and 18 sites were added in the 2004 breeding season in deciduous forests, and 32 in winter 2004 and 14 sites were added in the 2005 breeding season in larch plantations. Bird–environment relationships were explored using partial redundancy analysis and partial regression analysis. We used spatial variables derived from principal coordinates of neighbor matrices as explanatory variables to detect nonrandom spatial structure of bird communities. Variation in bird communities was mainly explained by stand and spatial variables for both forest types, whereas the effects of landscape variables were small. In plantations, important stand variables for both seasons included stand height, elevation, and the basal area of ...
