| study on the ecological distribution of alveolar echinococcus in hulunbeier pasture of inner mongolia, china. | a study on the ecological distribution of alveolar echinococcus was carried out in the hulunbeier pasture of inner mongolia, china during 1998 and 1999. animals examined included wolves (canis lupus), red foxes (vulpes vulpes), sand foxes (vulpes corsac), domestic dogs (canis familiaris), microtus brandti, meriones unguiculatus, citellus dauricus, allactaga sibirica, phodopus sungorus and ochotona daurica. three wolves were found to be infected with e. granulosus. two sand foxes were infected wi ... | 2004 | 15030006 |
| sheep grazing causes shift in sex ratio and cohort structure of brandt's vole: implication of their adaptation to food shortage. | livestock grazing has been demonstrated to affect the population abundance of small rodents in grasslands, but the causative mechanism of grazing on demographic parameters, particularly the age structure and sex ratio, is rarely investigated. in this study, we examined the effects of sheep grazing on the cohort structure and sex ratio of brandt's vole (lasiopodomys brandtii) in inner mongolia of china by using large manipulative experimental enclosures during 2010-2013. our results indicated tha ... | 2016 | 26331731 |
