Effect of Experiment Warming on Soil Fungi Community of Medicago sativa, Elymus nutans and Hordeum vulgare in Tibet

Journal of Fungi, 2023
The uncertainty response of soil fungi community to climate warming in alpine agroecosystems will limit our ability to fully exploit and utilize soil fungi resources, especially in alpine regions.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Top-down, bottom-up or middle-out? Avoiding extraneous detail and over-generality in marine ecosystem models [PDF]

, 2009
The paper by Hannah et al. (this volume) invokes foodweb theory and the ideas of complexity theory to guide the construction of models of intermediate complexity, which sacrifice explicit process detail to increase the number of interacting components of

Differential Influence of No-Tillage and Precipitation Pulses on Soil Heterotrophic and Autotrophic Respiration of Summer Maize in the North China Plain

Agronomy, 2020
It is important to strengthen the studies on the response of soil respiration components to tillage practices and natural precipitation in cropland. Therefore, soil heterotrophic respiration (RH) and autotrophic (RA) respiration were monitored by a root ...

The initial mass of residue can regulate the impact of Phragmites australis decomposition on water quality: a case study of a mesocosm experiment in a wetland of North China

Journal of Freshwater Ecology, 2021
Plant residue decomposition can significantly affect the water environment of wetland ecosystems. However, little is known about the trajectory and the key drivers of the different initial mass of residue (IMR) that regulate water quality.

Response of Aboveground Net Primary Production, Species and Phylogenetic Diversity to Warming and Increased Precipitation in an Alpine Meadow

Plants, 2023
The uncertain responses of aboveground net primary productivity (ANPP) and plant diversity to climate warming and increased precipitation will limit our ability to predict changes in vegetation productivity and plant diversity under future climate change

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Temporal Stability of Plant Species α-Diversity in Alpine Grasslands of the Tibetan Plateau and Their Implications for Biodiversity Conservation

Agronomy
The temporal stability of alpine plant α-diversity remains poorly understood, constraining predictions of biodiversity dynamics. Here, this study examined spatiotemporal patterns in the temporal stability of plant α-diversity (species richness, Shannon ...

Seed nutrient is more stable than leaf in response to changing multiple resources in an alpine meadow

Ecological Processes, 2023
Background It has been long thought that nitrogen (N), phosphorus (P) concentrations and their ratios (N:P) in metabolically active or functional organs (i.e., leaves) are less responsive to environmental changes. Little attention, however, has been paid

Warming alters elevation distributions of soil bacterial and fungal communities in alpine grasslands

Global Ecology and Conservation, 2022
It is still unknown whether climate warming can change the elevation distribution of soil microbial communities in alpine grasslands. Both species and phylogenetic β-diversity of soil bacterial and fungal communities were investigated at three alpine ...
