Effects of a Cattle and Sheep Dung Sand Barrier on Desertified Grassland Restoration in Alpine Area

open access: yesShuitu baochi tongbao, 2023
[Objective] The effects of plant fiber sand barriers, cattle and sheep dung barriers, and sand barriers comprised of cattle and sheep dung combined with plant fiber were studied in order to create effective sand barriers for the restoration of ...

Grazing decreases net ecosystem carbon exchange by decreasing shrub and semi‐shrub biomass in a desert steppe [PDF]

open access: goldEcology and Evolution
Livestock grazing can strongly determine how grasslands function and their role in the carbon cycle. However, how ecosystem carbon exchange responds to grazing and the underlying mechanisms remain unclear.

Snowmelt-triggered debris flows in seasonal snowpacks [PDF]

open access: yesE3S Web of Conferences, 2023
Snowmelt-triggered debris flows commonly occur in mountains. On 14 June 2019, a debris flow occurred on a steep, east-facing slope composed of unconsolidated glacial and periglacial sediments in Yosemite National Park. Originating as a shallow landslide,

Changes in plant species richness distribution in Tibetan alpine grasslands under different precipitation scenarios [PDF]

open access: yes, 2020
Species richness is the core of biodiversity-ecosystem functioning (BEF) research. Nevertheless, it is difficult to accurately predict changes in plant species richness under different climate scenarios, especially in alpine biomes.

Ecological Stoichiometric Characteristics in Organs of Ammopiptanthus mongolicus in Different Habitats

open access: yesPlants, 2023
The essence of plant ecological stoichiometry is to study the relationships between species and their environment, including nutrient absorption, utilization and cycling processes as well as the nutrient limitation of plants. Plants can regulate nutrient

A Real-Time Multiplexed Microbial Growth Intervalometer for Capturing High-Resolution Growth Curves

open access: yesFrontiers in Microbiology, 2019
Batch cultures are a low maintenance and routine culturing method in microbiology. Automated tools that measure growth curves from microorganisms grown in traditional laboratory glassware, such as Balch-type tubes, are not commercially available.

Drought Sensitivity and Trends of Riparian Vegetation Vigor in Nevada, USA (1985–2018)

open access: yesRemote Sensing, 2020
Dryland riparian areas are under increasing stress due to expanding human water demands and a warming climate. Quantifying responses of dryland riparian vegetation to these pressures is complicated by high climatic variability, which can create strong ...
