Spatiotemporal variation of composition and diversity of small mammals in Shenzhen Bao'an International Airport
Bird strikes are a serious threat to the safe operation of the global aviation industry,and many birds feed on small mammals.Therefore,understanding the species composition,density,distribution and population dynamics of small mammals inside and outside of airports is of great significance for airport bird control and flight safety.To under-stand the characteristics and spatiotemporal variation of the species,quantity,and diversity of small mammals in the run-way area and peripheral areas of Shenzhen Bao'an International Airport,four small mammal surveys were carried out in Shenzhen Airport from November 2021 to July 2022.A total of 152 small mammals from 6 species,4 genera,2 families,and 2 orders were captured by 1 343 effective clips.Rattus losea(37.50％)and Mus caroli(36.84％)were the dominant species.The capture rate of the four surveys was 11.66％±2.42％,and the seasonal variation of the capture rate was not significant.The total capture rate and rodent capture rate in the airport were significantly lower than those outside the airport.Species richness index and Shannon-Wiener index were the highest in November,while Pielou index was the lowest.Species richness index and Shannon-Wiener index inside the airport were slightly lower than outside the airport,while Pielou index was higher than outside the airport.The results indicate that small mammals should be controlled both inside and outside the airport to reduce the attraction of birds such as birds of prey,thereby reducing the risk of bird strikes at the airport.
