| Abstract: | A survey was conducted to study the species composition and diversity rule of ant communities in Mount Sejila in southeastern Tibet at altitudes of 2023 m to 4580 above the ground by sample plot method.A total of 16212 ant individuals of 24 species,belonging to 12 genera and 3 subfamilies,were collected,which included 17 known species and 7 unidentified species.Paratrechina sakurae(Ito) and Pheidole nietneri Emery are dominant species in Mount Sejila.The main indexes of ant communities in each plot on both west and east slopes at different altitudes were obtained as number of species 1-11(average 4.1),individual density 0.4-1272.6 heads per square meter(202.7),Shannon-Wiener index 0-1.4156(0.5346),evenness index 0.0833-0.9940(0.5362),and dominant index 0.3327-1.0000(0.7127).Number of species,individual density,and Shannon-Wiener index decrease with increasing altitude,which is in accord with the distribution law that the ant diversity in mountainous environment is mainly controlled by thermal factor(air temperature).There is no obvious regularity in evenness index and dominant index of the ant communities,but a distinct negative correlation was observed between the two indexes.The evenness index and dominant index of the ant communities are mainly influenced by forest structure and habitat factors.On the same slope,the similarity between the ant communities increases with increasing altitude,which is mainly restricted by diversity of vegetation types.However,the similarity between the ant communities on the east-west slope also increases with increasing altitude,which is mainly restrained by distance factor. |
