Increased availability of preferred food and decreased foraging costs from degraded grasslands lead to rodent pests in the Qinghai-Tibet Plateau

Frontiers in Ecology and Evolution, 2022
The increased population density of rodent species during ongoing grassland degradation further deteriorates its conditions. Understanding the effects of grassland degradation on rodent feeding habits is of great value for optimizing grassland management

Human activities modulate reciprocal effects of a subterranean ecological engineer rodent, Tachyoryctes macrocephalus, on Afroalpine vegetation cover

Ecology and Evolution, Volume 13, Issue 7, July 2023., 2023
In our study, we tested how human activities in terms of livestock grazing and settlements affect the reciprocal effects between vegetation and giant root‐rats. Our results show that increasing livestock grazing intensity causes increases in giant root‐rat burrow density indirectly through decreased vegetation cover.

Sympatric Speciation in Mole Rats and Wild Barley and Their Genome Repeatome Evolution: A Commentary

Advanced Genetics, Volume 3, Issue 4, December 2022., 2022
Our discovery in subterranean mammals and wild barley that noncoding genome or repeatome shows a mirror image of the coding genome suggests that they are both selected by the same ecological stresses and are both functionally adaptive. Abstract The theories of sympatric speciation (SS) and coding and noncoding (cd and ncd =repeatome) genome function ...

Gut Microbiome Alterations and Hepatic Metabolic Flexibility in the Gansu Zokor, Eospalax cansus: Adaptation to Hypoxic Niches

Frontiers in Cardiovascular Medicine, 2022
The Gansu zokor (Eospalax cansus), a typical subterranean rodent endemic to the Chinese Loess Plateau, spends almost its whole life in its self-constructed underground burrows and has strong adaptability to ambient hypoxia.

The role of herbivores in the grassland carbon budget for Three‐Rivers Headwaters region, Qinghai–Tibetan Plateau, China

Grassland Research, Volume 1, Issue 3, Page 207-219, September 2022., 2022
The herbivore carbon budget was estimated by an animal metabolic model developed in the Three‐Rivers Headwaters region. The livestock contributed 88% of the total consumed carbon that was returned 44% to grassland as feces and urine, and 40% through respiration and the remaining 4% in wildlife and 13% in livestock.

Vascular characteristics and expression of hypoxia genes in Tibetan pigs’ hearts

Veterinary Medicine and Science, Volume 8, Issue 1, Page 177-186, January 2022., 2022
Tibetan pigs have exhibited unique characteristics from low‐altitudes pigs and have adapted well to the Qinghai‐Tibet Plateau, but how this occurs is incompletely understood. We found that Tibetan pigs had larger diameters and higher densities of arterioles than Landrace pigs (p < 0.05), and these features have a similar variation with the expression ...

The hypoxia adaptation of small mammals to plateau and underground burrow conditions

Animal Models and Experimental Medicine, Volume 4, Issue 4, Page 319-328, December 2021., 2021
Small mammals have evolved mechanisms of hypoxia adaptation living under plateau and underground burrow conditions. Abstract Oxygen is one of the important substances for the survival of most life systems on the earth, and plateau and underground burrow systems are two typical hypoxic environments.

Adaptation of mammals to hypoxia

Animal Models and Experimental Medicine, Volume 4, Issue 4, Page 311-318, December 2021., 2021
Soil profile and a blind mole living underground. Abstract Oxygen plays a pivotal role in the metabolism and activities of mammals. However, oxygen is restricted in some environments—subterranean burrow systems or habitats at high altitude or deep in the ocean—and this could exert hypoxic stresses such as oxidative damage on organisms living in these ...

Microbial Biogeography along the Gastrointestinal Tract Segments of Sympatric Subterranean Rodents (Eospalax baileyi and Eospalax cansus)

Animals, 2021
In this study, based on high-throughput sequencing technology, the biodiversity and the community structure of microbiota in different GIT segments (the stomach, small intestine, cecum and rectum) of plateau zokors and Gansu zokors were studied and ...
