在韩国片断化林区内道路对小型啮齿类种群的影响

The road effect on small rodent population is investigated at 8 fragmented forest areas in the Baekdudaegan moun-tain range, South Korea in September 2001, We especially focused on the distribution and body condition of small rodents near the roads, Korean field mouse (Apodemus peninsulae) seems to be more sensitive to the existence of a road than striped field mouse (Apodemus agradus), Korean field mouse prefers interior forest area to around road. Striped field mouse is a habitat generalist and has wide distributional range around road, but Korean field mouse is forest-inhabiting species and their distribu-tion is limited in forest area. These results suggest the effect of road is different on each small rodent species and their habitat preferences.     

红喉歌鸲在韩国雪岳山国立公园大青峰地区的生境选择

自2001年5月至10月间,在韩国雪岳山国立公园大青峰地区进行了红喉歌鸲(Luscinia calliope)的生境选择研究。繁殖种群的调查结果表明,该研究地区可分成此种鸟的高、中、低3种密度分布区。红喉歌鸲多选择岳桦(Betula ermanii)和雪松(Pinus pumila)林为其栖息地,并喜欢在矮丛林和稠密灌丛中活动。表1参9。     

Characteristics of bird communities between slope and valley in natural deciduous forest, South Korea

本研究在弄清韩国桂坊山(374030N,128301E)天然落叶阔叶林斜坡和山谷中鸟类群落间的特征差异。调查结果表明:两地鸟类群落的种类组成、丰富度、鸟种多样性及群落结构都有不同。森林的垂直结构特别是林下覆被度及胸高直径分布多显不同。两地生境结构的不同必然影响着鸟类对可利用生境的选择。表6图2参19。
