Abstract

Objective To investigate the individual and interactive impact of various factors (including meteorological conditions, the normalized difference vegetation index[NDVI], and flea index) on the population density of Meriones unguiculatus in Xilingol League, Inner Mongolia Autonomous Region, China.Methods The data of M. unguiculatus density and body flea index as well as meteorological and NDVI data in Xilingol League from 2012 to 2021 were collected. Generalized additive models were employed to analyze the factors influencing the gerbil density with R 4.2.2 software.Results The density of M. unguiculatus exhibited a significant temporal trend (F=3.129, P=0.004). Significant nonlinear negative effects on M. unguiculatus density were observed for the flea index (F=1.833, P=0.044) and monthly average relative humidity (F=2.949, P=0.011). Lag-3-month monthly average minimum temperature had a significant nonlinear positive effect on the gerbil density (F=2.418, P=0.032):with rising monthly average minimum temperature, the gerbil density initially increased, then declined, and increased again. A linear positive correlation existed between lag-1-month monthly average sunshine duration and the gerbil density (F=7.876, P=0.005). Lag-2-month monthly average air pressure and the gerbil density showed an inverted U-shaped relationship (F=4.752, P=0.002), which was positive when monthly average air pressure was <880 hPa and negative otherwise. Interactive effects were found between the flea index and lag-3-month monthly average minimum temperature (F=2.689, P=0.009) and between the flea index and monthly average relative humidity (F=2.644, P=0.017) on the gerbil density.Conclusion The flea index, monthly average minimum temperature, monthly average relative humidity, monthly average sunshine duration, and monthly average air pressure can influence the density of M. unguiculatus, and lag effects and interactive effects exist among these influencing factors.
