The plateau pika (Ochotona curzoniae) is an underground-dwelling mammal, native to the Tibetan plateau of China. A set of 10 polymorphic microsatellite loci has been developed earlier. Its reliability for parentage assignment has been tested in a plateau pika population. Two family groups with a known pedigree were used to validate the power of this set of(More)
Host population density is positively associated with the strength of social interactions or the frequency of physical contacts, and thus potentially influences microbial transmission among individuals. However, the relationship between host density and gut microbiota remains unknown. Here, we characterized the gut microbiota of plateau pikas (Ochotona(More)
BACKGROUND Plateau pikas (Ochotona curzoniae, Hodgson, 1858) are viewed as a pest in the Tibetan Plateau meadow ecosystem when their population densities are high. Traditional culling using rodenticides often poses a high risk to non-target species and even to humans. In this study, an investigation was made of the infertility effects of quinestrol (E),(More)
Fertility control is an alternative non-lethal method in the management of rodents. Previous modeling suggests that the efficacy of male sterilization depends on mating systems of animals, but behavioral mechanisms of male sterilization have not been investigated. Here we investigated the behavioral mechanism of the sterilant quinestrol in reducing the(More)
Small herbivores play keystone functional roles in grassland ecosystems. Recognising the combined effects where herbivores co-exist is important for guiding grassland restoration and biodiversity conservation. On the Tibetan Plateau, both plateau pikas and Himalayan marmots are regarded as pests by Tibetan people and local government, but little is known(More)
Dispersal, which is a crucial process in animal population and evolutionary ecology, is considered personality dependent. The fitness consequences of dispersal are important. However, they are difficult and rarely measured in wild populations. In this study, we investigated the behaviour and reproductive fitness in a plateau pika (Ochotona curzoniae)(More)
The gut microbial communities of animals play key roles in host evolution. However, the possible relationship between gut microbiota and host divergence time remains unknown. Here, we investigated the gut microbiota of eight Glires species (four lagomorph species and four rodent species) distributed throughout the Qinghai-Tibet plateau and Inner Mongolia(More)
Small mammals mediate trajectories of vegetation change where both their density and the growing season are moderated by temperature and precipitation. On the Tibetan Plateau, the cold and arid climate particularly restricts the plant growing season, but the role of mammals’ density and climate in moderating small mammal populations remains unknown. We(More)
Plateau pikas are seasonally breeding small herbivores that inhabit the meadow ecosystem of the Qinghai-Tibetan Plateau. Testis regression in plateau pikas begins in early June, and the male pikas are completely infertile, with a dramatically reduced testis size, in late July. In this study, a decreased germ cell number in the testes was first noted in(More)
Quinestrol has shown potential for use in the fertility control of the plateau pika population of the Qinghai-Tibet Plateau. However, the environmental safety and fate of this compound are still obscure. Our study investigated degradation of quinestrol in a local soil and aquatic system for the first time. The results indicate that the degradation of(More)
