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。
