新疆天山中-西段不同垂直带蚂蚁物种多样性
Ant diversity along gradient in the middle-western section of Tianshan Mountains in Xinjiang
摘要
Abstract
[Objective]In order to reveal the diversity of ant species in different vertical zones in Tianshan Mountains,the ant community structure,relationship between species diversity and altitude and vegetation in the middle-western section of Tianshan Mountains were studied.[Method]Ant communities in four vertical zones were surveyed by plot sampling and searching methods.The sampling adequacy was tested by Estimate S 9.1.0,and the diversity indexes in different zones were calculated.The correlations between diversity indexes and altitude and vegetation characteristics were analyzed by SPSS 24.0,if the correlation between species diversity and elevation was significant,both linear and binomial models were used for fitting,the fitting was evaluated based on R2 value while the significance was tested.[Result]A total of 136 247 ants were collected,and 29 species belonging to 12 genera and 2 subfamilies were recognized.Tetramorium caespitum,Lasius niger and Formica fusca were the dominant species of the middle-western section of Tianshan Mountains in Xinjiang.Sampling adequacy analysis showed that the most of ant species were collected.The richness of ant species of the four vertical zones as follows:Dushanzi vertical zone(18 species)＞Narathi vertical zone(14 species)＞Kuqa vertical zone(13 species)＞Ulastai vertical zone(10 species).Diversity analysis showed that the ant species diversity of the middle-western section of Tianshan Mountains generally decreased with the altitude increasing.The species number and diversity index of the four vertical zones were significantly negatively correlated with the altitude change.On the four vertical zones,the correlation significance between evenness index and altitude was not the same,the change trends of binomial and linear models also lacked regularity.There was no significant correlation between dominance index and elevation change,but the binomial model analysis of each vertical zone showed a trend of increasing firstly and then decreasing with the elevation increasing.Community similarity analysis found that the similarity coefficient of ant community was between 0.166 7 to 0.600 0(average 0.289 0),which was at the medium dissimilarity level,and indicating significant differentiation among ant communities.Correlation analysis showed that the species number was significantly positively correlated with tree canopy density,while the correlation between other diversity indexes and vegetation characteristics was not significant.[Conclusion]Altitude significantly affected ant species diversity in this region,while slope,humidity and vegetation also play an important role.In the Tianshan area of Xinjiang,under the influence of multiple factors such as vegetation types mainly being grassland and shrubland,hot and dry climate,high altitude and large temperature difference,and the ecosystem in this region is relatively fragile,so the protection of biodiversity in this region should be strengthened.关键词
