Blunted hypoxic pulmonary vasoconstrictive response in the rodentOchotona curzoniae(pika) at high altitude [PDF]

American Journal of Physiology-Heart and Circulatory Physiology, 1998
To investigate the possible mechanisms of adaptation to chronic hypoxia in the pulmonary circulation, we made direct measurements of pulmonary arterial pressure (Ppa) in 10 awake pika rodents that were transported to Xining, People’s Republic of China (altitude 2,260 m) after being captured at 4,300 m and in 10 Wistar rats in a decompression chamber ...

Evidence of Intraspecific Adaptive Variation in the American Pika (Ochotona princeps) on a Continental Scale Using a Target Enrichment and Mitochondrial Genome Skimming Approach

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Montane landscapes present an array of abiotic challenges that drive adaptive evolution amongst organisms. These adaptations can promote habitat specialisation, which may heighten the risk of extirpation from environmental change. For example, higher metabolic rates in an endothermic species may contribute to heightened cold tolerance, whilst ...

Virus communities are associated with the degradation of recalcitrant carbon during the corpse decay of plateau pika (Ochoton curzoniae)

Grassland Research, Volume 4, Issue 3, Page 281-293, September 2025.
Abstract Background It has been reported that bacteria and fungi play a vital role in soil biogeochemical cycles during the decomposition of animal corpses. However, it is poorly understood how the viral composition and function of grassland soil change during the decay of wild mammal corpses.

Luteimonas chenhongjianii, a novel species isolated from rectal contents of Tibetan Plateau pika (Ochotona curzoniae)

International Journal of Systematic and Evolutionary Microbiology, 2020
Two Gram-stain-negative, strictly aerobic, bright-yellow-pigmented and rod-shaped bacteria (strains 100069 and 100111T) with a single polar flagellum were isolated from the rectal contents of plateau pika (Ochotona curzoniae). Based on the results of nearly full-length 16S rRNA gene sequence and phylogenetic analyses, strains 100069 and 100111T belong ...

Active Restoration of Carbon Poor Degraded Grassland Accelerated Subsoil Carbon Accumulation and Turnover

Earth's Future, Volume 13, Issue 9, September 2025.
Abstract Grassland degradation and its impact on soil carbon cycle is of worldwide concern, but optimal restoration strategies remain uncertain. We determined temperature sensitivity of organic cabon mineralization (CO2‐Q10) and the mechanisms underlying changes in soil organic carbon (SOC) content across non‐restored and restored grasslands on the ...
