Gut Microbiota Provide Co‐Existing Strategies for Two Species of Symmetrically Distributed Rodents in Competition for Food

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Gut microbiota provides an effective strategy for sympatric proximal species to coexist in interspecific competition. ABSTRACT Gut microbiota provides an effective strategy for sympatric proximal species to coexist in interspecific competition. In the present study, 16S rRNA gene sequencing was used to investigate the gut microbial of the Cricetulus ...

Differential Response of Community Biomass Temporal‐ and Spatial‐ Stabilities to Nitrogen Addition in an Alpine Meadow on the Tibetan Plateau

Journal of Vegetation Science, Volume 36, Issue 3, May/June 2025.
This study investigates how nitrogen addition affects temporal and spatial stability of community biomass in alpine meadows. Using 5 years of experimental data, it highlights the key roles of dominant species' asynchrony and shows that nitrogen addition enhances temporal but not spatial stability, despite reduced species richness, emphasizing the need ...

Losses of low‐germinating, slow‐growing species prevent grassland composition recovery from nutrient amendment

Global Change Biology, Volume 30, Issue 4, April 2024.
An incomplete recovery in plant diversity and a directional shift in species composition from grass dominance to forb dominance were observed, and the historically dominant sedges with low germination rate and slow growth rate and nitrogen‐fixing legumes with low germination rate were unable to re‐establish after nutrient addition ceased.

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Microbial community composition in the dung of five sympatric European herbivore species

Ecology and Evolution, Volume 14, Issue 3, March 2024.
Abstract The dung microbiome is a complex system that is highly influenced by species and diet. This study characterized the dung bacterial and fungal communities of five herbivore species inhabiting the National Park Zuid‐Kennemerland, the Netherlands.

Alpine grassland degradation intensifies the burrowing behavior of small mammals: evidence for a negative feedback loop

Integrative Zoology, Volume 19, Issue 2, Page 240-252, March 2024.
Our study demonstrates the changes of behaviour, increased burrowing and enlarged colony territories, of pikas in response to grassland degradation. Our results indicate that the negative impact of plateau pikas on grasslands is through such changes of burrowing and ranging behaviors instead of “population explosion” due to their preference of degraded

Topographic barriers drive the pronounced genetic subdivision of a range‐limited fossorial rodent

Molecular Ecology, Volume 33, Issue 5, March 2024.
Abstract Due to their limited dispersal ability, fossorial species with predominantly belowground activity usually show increased levels of population subdivision across relatively small spatial scales. This may be exacerbated in harsh mountain ecosystems, where landscape geomorphology limits species' dispersal ability and leads to small effective ...

Effect of Nitrogen Addition on Selection of Germination Trait in an Alpine Meadow on the Tibet Plateau [PDF]

, 2021
Seed germination requirements may determine the kinds of habitat in which plants can survive. We tested the hypothesis that nitrogen (N) addition can change seed germination trait-environmental filter interactions and ultimately redistribute seed ...

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 ...

Molecular Characterization and Expression Analysis of Insulin-like Growth Factor-1 and Insulin-like Growth Factor Binding Protein-1 Genes in Qinghai-Tibet Plateau and Lowland [PDF]

, 2015
Insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-1 (IGFBP-1) play a pivotal role in regulating cellular hypoxic response.
