Response of Soil Respiration to Grazing in an Alpine Meadow at Three Elevations in Tibet

The Scientific World Journal, 2014
Alpine meadows are one major type of pastureland on the Tibetan Plateau. However, few studies have evaluated the response of soil respiration (Rs) to grazing along an elevation gradient in an alpine meadow on the Tibetan Plateau.

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.

Upscaling key ecosystem functions across the conterminous United States by a water-centric ecosystem model [PDF]

, 2011
We developed a water-centric monthly scale simulation model (WaSSI-C) by integrating empirical water and carbon flux measurements from the FLUXNET network and an existing water supply and demand accounting model (WaSSI).

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

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 ...

Continental scale variability in ecosystem processes: Models, data, and the role of disturbance [PDF]

, 1997
Management of ecosystems at large regional or continental scales and determination of the vulnerability of ecosystems to large-scale changes in climate or atmospheric chemistry require understanding how ecosystem processes are governed at large spatial ...

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

Molecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.
