Abstract:

Objective To better understand the changes of mosquito biodiversity patterns along latitude gradient in arid wetlands of north of Xinjiang, and explain the correlation between species abundance and environment through redundancy analysis(RDA). Methods Mosquitoes were collected from 5 arid wetlands with CO2 light-trap, and α biodiversity index, β biodiversity index were estimated with consideration of latitude increase, and relation between species abundance and environment was analyzed by RDA ordination. Results A total 20 731 mosquitoes of 16 species in 5 genera were collected in subject area, and Aedes vexans which accounted for 55.98% of total captured was the predominant species in arid wetlands of north Xinjiang Uygur Autonomous Region. The indices of 5 wetlands, from south to north, were 8, 11, 5, 9, 8 for richness, 1.23, 1.11, 0.24, 0.57, 0.35 for Shannon-Weiner index, and 0.59, 0.46, 0.15, 0.26, 0.17 for Pielou index, respectively. And the Cody index was 5.5, 4.0, 2.0, 2.5, between two wetlands neighbored respectively. And eigenvalues were 0.510, 0.256, 0.142, 0.078, species-environment correlations were 0.999, 0.999, 0.995, 0.996, for 4 axes respectively, and Monte Carlo permutation tests were significant statistically for each axis(P<0.01. Conclusion Aedes vexans was the predominant species in arid wetlands of north frontier of Xinjiang Uygur Autonomous Region. Both α biodiversity index and β biodiversity index showed overall decline with increasing latitude, and no obvious change was observed through γ biodiversity analysis. Precipitation had the most significant impact on abundance, followed by temperature and light hours. And comprehensive effect of meteorological variables contributed to the pattern of species abundance in 5 wetlands in north of Xinjiang.
