重引入普氏野马、蒙古野驴和鹅喉羚的秋季营养生态位
Trophic Niche Width and Overlap of Equus przewalskii, E. hemionusand Gazella subgutturosain Autumn
摘要
Abstract
In this study,the fresh excrements of Equus przewalskii,E.hemionus and Gazella subgutturosa were systematically collected from the Qiaomuxibai of Karamori Natue Reserve in Xinjiang in autumn 2009.Fecal microscopic means were used to analyze the habitats of the abovementioned three species and their food niche.The results show that the 3 species have similar diet in terms of types,but different in terms of proportion,where Stipa spp.are the main food sources of these species,and their diet percentages are 43.63%,49% and 44.65% respectively.The nutritional niche breadths of E.przewalskii,E.hemionus and G.subgutturosa are 0.634,0.619 and 0.539 respectively.The nutritional niche overlap values of E.przewalskii and E.hemionus,E.przewalskii and G.subgutturosa,E.hemionus and G.subgutturosa are 0.98,0.986 and 0.962 respectively,and the extent of nutritional niche overlap between the three species is 0.477.The three species are very similar in terms of consuming food resources.关键词
