Tendbrionidae Fauna and Ecological Distribution in Ningxia Helan Mountain Nature Reserve
摘要
Abstract
The tendbrionidae fauna and ecological distribution in Ningxia Helan Mountain Nature Reserve were investigated from 2007 to 2009. The results show that 50 species belonging to 20 genera and 4 subfamilies. The subfamily tenebrioninae is the predominant group (11 genera and 24 species), occupying 48 ％ of the total species. The subfamily pimelinnae (7 genera and 20 species) is the next, accounting for 40％. Analysis on the faunal composition from the view of the world animal fauna, the main is CenroAsiatic species. In the zoogeographic regions of China, the Mongolia-Xinjiang Region (32 species for 64 ％)are predominant types for 7 distribution patterns these distribution patterns of Ningxia Helan mountain,the Mongolia Xinjiang-North China Region are 10 species for 20％. 50 species of family tenebrionidae are clustered into 4 ecological species groups based on the characteristics of ecological distribution. The species and individual numbers of darkling beetles is related to altitude and plant cover where they lived. With the increase of altitude and the simplicity of the plant cover, the number of darkling beetles reduced. The species occurs mainly on the desert grassland and woodland steppe in Ningxia Helan Mountain. There are some alpine species in coniferous-broadleaved forests, coniferous forests and alpine meadow.关键词
