Abstract: Objective To investigate the time niche of ectoparasites of the rodent in Dongling Mountain,Western Beijing.Methods The niche breadth and niche overlap of 18 dominant species of ectoparasites in resource-series formed by 7 species of rodents were calculated.The species of ectoparasites with great niche overlap were classified as one niche overlap group by clustering analysis.Results The values of time niche breadth of Neopsylla specialis,Ixodes persulcatus,Laelaps micromydis,and Lepotrombidium orientale were the widest in different ectoparasite type.The value of niche overlap of the dominant ectoparasites seen to be high,e.g.Laelaps echidninus and L.orientale,N.bidentatiformis and N.specialis,Haemogamasus calandrellus and N.specialis.ConclusionThose ectoparasite species with high value of niche overlap emerged on the same season.
