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 ...

Pika burrow and zokor mound density and their relationship with grazing management and sheep production in alpine meadow

Ecosphere, 2020
Plateau pikas (Ochotona curzoniae) and plateau zokors (Myospalax baileyi) occur naturally in the alpine meadow of the Qinghai–Tibet Plateau (QTP). Their feeding and burrowing activities affect plant composition and soil properties (e.g., soil carbon ...

Gut Microbiome Changes in Captive Plateau Zokors ()

Evolutionary Bioinformatics, 2021
Wild-caught animals must cope with drastic lifestyle and dietary changes after being induced to captivity. How the gut microbiome structure of these animals will change in response receives increasing attention. The plateau zokor ( Eospalax baileyi ), a typic subterranean rodent endemic to the Qinghai-Tibet plateau, spends almost the whole life ...

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 ...

“Into and Out of” the Qinghai‐Tibet Plateau and the Himalayas: Centers of origin and diversification across five clades of Eurasian montane and alpine passerine birds

Ecology and Evolution, Volume 10, Issue 17, Page 9283-9300, September 2020., 2020
The Qinghai‐Tibet Plateau (QTP) is considered a source region for colonization of adjacent areas such as the northern Palearctic. Using an ancestral area reconstruction approach on a phylogeny of 279 bird species, we suggest that faunal exchange between the QTP and adjacent regions was bidirectional through time and the QTP region has harbored both ...

p53 gene cloning and response to hypoxia in the plateau zokor, Myospalax baileyi [PDF]

Animal Biology, 2018
AbstractThe plateau zokor (Myospalax baileyi) is a specialized subterranean rodent that lives on the Qinghai-Tibet Plateau. The species has evolved a series of strategies to adapt to its hypoxic environment and hypercapnia.p53is a tumour suppressor gene that plays a crucial role in the cellular response to hypoxia by inducing cell cycle arrest, cell ...

Impact of groundwater table and plateau zokors (Myospalax baileyi) on ecosystem respiration in the Zoige Peatlands of China. [PDF]

PLoS ONE, 2014
Peatlands contain large amount of carbon stock that is vulnerable to release into the atmosphere. Mostly because of human impact, the peatlands at Zoige Wetlands face severe degradation, and the groundwater table is now lower than before, which has ...

Oxygenation properties and underlying molecular mechanisms of hemoglobins in plateau zokor (Eospalax baileyi) [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2019
The plateau zokor ( Eospalax baileyi) is a species of subterranean rodent endemic to the Tibetan Plateau. It is well adapted to the cold and hypoxic and hypercapnic burrow. To study the oxygenation properties of plateau zokor hemoglobins (Hbs), we measured intrinsic Hb-O2affinities and their sensitivities to pH (Bohr effect); CO2; Cl−, 2,3 ...

Divergence Linked to Possible Ecological Speciation in Blind Mole Rats: Integration of Thermal Biology and Bite Force in the Upper Galilee Blind Mole Rat (Nannospalax galili)

Integrative Zoology, EarlyView.
Basalt‐dwelling blind mole rats maintain lower body temperatures, show greater post‐digging thermal increases, and dig more efficiently than those from rendzina soils. Although metabolic rates and bite force did not differ between populations, these thermal and physiological shifts align with the greater mechanical resistance and seasonal hypoxia of ...
