Brandt\u2019s voles are the dominant rodent species in typical steppe habitat and are widely distributed in Inner Mongolia, China, but the prevalence of parasites in Brandt\u2019s voles are poorly reported. In this study, we investigated the prevalence of six intestinal parasites in Brandt\u2019s voles in May, June, July, and August 2022 around the Xilingol Grassland in Inner Mongolia, China. The results showed that Syphacia obvelata, Aspiculuris tetraptera, and Trichostrongylidae family were the dominant intestinal parasites in Brandt\u2019s voles that we captured in this study, and the infection rates of the three parasites were significantly higher in males than females, which showed obvious male-biased parasitism. Season and human activities such as grazing had no significant effect on the infection rates for different parasites, while the parasite reproduction level was higher when the ambient temperature was around 18 \u00b0C. Sexual size dimorphism was ubiquitous in Brandt\u2019s voles, and it was mainly manifested by the differences in body weight and length between males and females. Simple linear regression analysis showed a significant positive correlation between bodyweight and parasite infection rates, so the sex-biased parasitism in Brandt\u2019s voles could be explained by the body size hypothesis, as a larger body could provide more ecological niches for parasitic infection.<\/jats:p>","DOI":"10.3390\/ani13081290","type":"journal-article","created":{"date-parts":[[2023,4,10]],"date-time":"2023-04-10T03:15:57Z","timestamp":1681096557000},"page":"1290","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Male-Biased Parasitism of Brandt\u2019s Voles (Lasiopodomys brandtii) in Inner Mongolia, China"],"prefix":"10.3390","volume":"13","author":[{"given":"Gaojian","family":"Li","sequence":"first","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qinghe","family":"Wang","sequence":"additional","affiliation":[{"name":"Nanyang Wild Animals and Plants Protection Station, Nanyang 473000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min","family":"Zhang","sequence":"additional","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Hu","sequence":"additional","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuyi","family":"Han","sequence":"additional","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Xiang","sequence":"additional","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guohui","family":"Yuan","sequence":"additional","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongxuan","family":"He","sequence":"additional","affiliation":[{"name":"National Research Center for Wildlife-Borne Diseases, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"355","DOI":"10.1038\/nature04153","article-title":"Superspreading and the effect of individual variation on disease emergence","volume":"438","author":"Schreiber","year":"2005","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2015","DOI":"10.1126\/science.1074196","article-title":"Parasites as a viability cost of sexual selection in natural populations of mammals","volume":"297","author":"Moore","year":"2002","journal-title":"Science"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1109","DOI":"10.1016\/j.ijpara.2013.07.003","article-title":"Life history strategy influences parasite responses to habitat fragmentation","volume":"43","author":"Froeschke","year":"2013","journal-title":"Int.
