“…The Phrynocephalus genus contains over 40 species of toad-headed lizards, some of which are widely distributed in the QTP ( 2 ), including the species Phrynocephalus erythrurus and Phrynocephalus theobaldi , which are considered to be the highest-altitude lizard species in the world ( 3 ). Living restricted to the QTP with its harsh climate, these species need to have the adaptive ability to survive in the hypoxic, arid, natural conditions ( 4 ). As global warming continues, the QTP is being affected as a vulnerable ecological environment sensitive to natural and anthropogenic disturbances ( 5 ).…”

The Phrynocephalus lizards inhabiting the Qinghai-Tibet Plateau (QTP) are considered to be the highest-altitude lizard species in the world, and they have been added to the IUCN list of threatened species. Living in the QTP with hypoxic, arid, natural conditions, the lizards presented a unique pattern of gut virome, which could provide both positive and negative effects, such as the enrichment of functional genes and the dissemination of antibiotic resistance genes (ARGs).

“…In contrast, we strongly suggest to strictly protect all -mature and secondary -natural forests from any human interventions -apart from a potential enrichment planting with tree species well adapted to the predicted, dryer and warmer future climatic conditions. The target here should be to allow the eventual natural domination of well-adapted long-lived late-succession tree species that commonly store significant amounts of carbon in their trunks (Smith and Knapp, 2003), with natural disturbances allowing for an overall heterogeneous forest environment that not only sustainably stores carbon, but also supports the extremely high levels of biodiversity encountered across our study region (Sun et al, 2021). S2).…”

Implementation of the Natural Forest Protection Project and Grain for Green Programme in China has promoted forest restoration, increased productivity, and enhanced the carbon stocks. However, few studies have characterized temporal and spatial variation in productivity and ecological stability in planted and natural forests and evaluated the factors driving such variation. In this study, we used 1399 permanent forest plots to identify change patters in the productivity and temporal stability of above-ground biomass (AGB) and evaluated the factors driving these changes in planted and natural forests in Sichuan Province, China. The mean temporal stability of AGB was higher for natural forest than for planted forest from 1979 to 2017; While, the productivity of planted forest was higher. The stability decreased at a rate of -0.013 yr-1 in entire natural forest and -0.011 yr-1 in planted forests, and the productivity of natural forest decreased significantly over time, with a slope of -0.0065 Mg ha-1 yr-1 per calendar year. Altitude, latitude, annual precipitation, and stand age dominated variability in the productivity and AGB stability of natural forest. Richness, tree density, and stand age were the determinants of productivity and stability in planted forest. Our results suggest that selective thinning and enriching species richness and forest stand age can effectively balance the productivity and biomass temporal stability of planted forests. Older natural forests still need to be strictly protected under climate change.

“…The Qinghai–Tibetan Plateau is known as the “roof of the world” and “third pole of the earth” ( Sun et al, 2021 ), and it occupies 26% of the Chinese land area ( Wu, 2001 ). Residents of this area rely heavily on animal husbandry to financially support themselves.…”

“…Residents of this area rely heavily on animal husbandry to financially support themselves. However, this area is characterized by strong ultraviolet radiation, low atmospheric O 2 partial pressure, and low temperatures throughout the year ( Zha et al, 2016 ; Sun et al, 2021 ), which pose several challenges to animals in the region ( Cheviron and Brumfield, 2012 ; Guo et al, 2014 ).…”

The production efficiency of dairy cows is affected by altitude, with lower efficiency reported at higher altitudes. However, only a few studies have investigated the digestion performance, serum antioxidative characteristics, rumen fermentation performance, and rumen bacteria of Sanhe heifers at different altitudes. Therefore, in this study, we explored the effects of altitude on these aspects of Sanhe heifers. We evaluated the effects of altitude on the apparent digestibility of nutrients, serum antioxidative characteristics, rumen fermentation parameters, and rumen bacteria in Sanhe heifers. Twenty Sanhe heifers from the same herd and managed with the same practice were used. However, the heifers were from two regions in China: 10 were fed in Hulunbuir City, Inner Mongolia Autonomous Region (119°57′E, 47°17′N; approximately 700 m altitude, named LA) and 10 were fed in Lhasa City, Tibet Autonomous Region (91°06′E, 29°36′N; approximately 3,750 m altitude, named HA). The dry matter intake (DMI), average daily gain (ADG), and DMI/ADG ratio were higher (p < 0.05) in LA than in HA heifers, whereas the apparent total tract digestibility of dry matter, ether extract, and crude proteins were higher (p < 0.05) in the HA group. Compared with LA heifers, the HA heifers showed decreased (p < 0.05) serum concentrations of superoxide dismutase and glutathione peroxidase and increased serum concentration of hydrogen peroxide (p < 0.05). Altitude did not significantly affect the volatile fatty acid concentration in the rumen, but HA presented a lower acetate-to-propionate ratio than LA. The 16S rRNA gene sequencing data showed that altitude significantly affected the rumen microbial composition. At the phylum level, the HA heifers presented a lower relative abundance of Actinobacteria (p < 0.05) and higher relative abundance of Spirochaetae (p < 0.05) than the LA heifers. The correlation analysis revealed that the operational taxonomic units belonging to the genus Prevotella_1 were correlated (p < 0.05) with altitude and DMI. The results indicate that altitude can influence the apparent digestibility of nutrients, serum antioxidant capacity, rumen fermentation, and rumen bacteria composition of Sanhe heifers. The study provides insights into the adaptation mechanism of Sanhe heifers to high-altitude areas.
