Response of Plant Community Characteristics and Soil Factors to Topographic Variations in Alpine Grasslands

Plants
Topography has an important influence on plant–soil relationships. However, research on plant–soil relationships in alpine grassland at the slope aspect and slope position scales is currently inadequate.

Fluxes of CO2,CH4 and N2O from alpine grassland in the Tibetan Plateau

, 2003
Using static chamber technique,fluxes of CO2,CH4 and N2O were measured in the alpine grassland area from July 2000 to July 2001,determinations of mean fluxes showed that CO2 and N2O were generally released from the soil,while the alpine grassland ...

Dynamic rhizosphere C:N:P stoichiometry of plants, soils and microbial biomass under different grazing patterns

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Analysing grassland ecological stoichiometry is crucial for evaluating ecosystem quality and health via energy flow and elemental equilibrium. Grazing is a dominant human activity shaping alpine grasslands on the Qinghai–Tibet Plateau (QTP), yet few studies have used ...

Grazing increased alpine grassland soil respiration rates on the Tibetan Plateau

Frontiers in Soil Science
IntroductionGrazing activities were intensive in alpine grasslands and may alter the soil respiration rates across the Tibetan Plateau. However, grazed alpine grassland soil respiration rates and their underlying driving mechanisms remain unclear across ...

Nitrogen addition alters adaptive strategies of a dominant plant species in an alpine meadow via shifts in traits and trait coordination

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition significantly impacts plant functional traits in alpine meadows, yet the adaptive strategies of dominant species remain unclear. Understanding these strategies is crucial for predicting alpine grassland vegetation changes and ecosystem ...

Ecological Restoration Projects Adapt Response of Net Primary Productivity of Alpine Grasslands to Climate Change across the Tibetan Plateau

Remote Sensing
Alpine grassland is sensitive to climate change, and many studies have explored the trends in alpine vegetation. Most research focuses on the effects of climate warming and increased humidity on vegetation greening. However, less attention has been given

Integrating experimental and observational approaches facilitates scaling species interactions to biodiversity patterns

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract To investigate how niche and fitness differences determine the outcome of species interactions and shape local biodiversity patterns, research has typically focused on either simplified experimental systems that test specific mechanisms or observational studies where ...

Invasion Alters Plant and Mycorrhizal Communities in an Alpine Tussock Grassland

Oecologia
Abstract Plant invasions now impact even the world’s most remote ecosystems, including alpine zones, altering key mutualisms that affect ecosystem functions. Plant-mycorrhizal associations can be sensitive to invasion, but previous studies have been limited in the types of mycorrhizas examined, favouring invaders that host arbuscular ...

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds

Journal of Animal Ecology, EarlyView.
Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

Insect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.
