Analysing the spatial variation of soil respiration during the early growing season of different grasslands in China [PDF]

PeerJ
Background As one of the most essential vegetation types, grasslands play a vital role in the global carbon cycle. However, current researches on the spatial variation (SV) of soil respiration (Rs) in grasslands faces great uncertainties.

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Temporal stability responses to nitrogen addition in Tibetan alpine grasslands: A community composition perspective

Journal of Integrative Agriculture
Plant community composition typically undergoes progressive changes along environmental gradients. However, most experimental studies have focused on individual communities, so it remains unclear how exogenous nutrient inputs affect the stability of ...

Sustainability assessment of organic dairy farms in mountainous areas of Austria [PDF]

, 2018
Dairy farming plays a major role in mountainous regions of Austria, mostly due to high proportion of grasslands. In general, Austria’s dairy farming faces challenges regarding sustainability, e.g.

Response of carbon dioxide emissions to sheep grazing and N application in an alpine grassland – Part 2: Effect of N application [PDF]

, 2014
Widespread nitrogen (N) enrichment resulting from anthropogenic activities has led to great changes in carbon exchange between the terrestrial biosphere and the atmosphere. Grassland is one of the most sensitive ecosystems to N deposition.

Low‐nitrogen addition amplifies the positive effect of grazing exclusion on plant diversity and community stability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Grazing exclusion is widely used for grassland restoration but often improves productivity slowly, whereas nitrogen (N) addition can rapidly boost productivity yet may erode plant diversity and community stability over the long term.

Geographical patterns and drivers of plant productivity and species diversity in the Qinghai-Tibet Plateau

Plant Diversity
The Qinghai-Tibet Plateau (QTP) has three main grassland types: alpine meadow, alpine steppe, and alpine desert steppe. In this study, we asked how plant productivity and species diversity vary with altitude, longitude and latitude in alpine grasslands ...

Meadow birds in Sweden – population trends, effects of restoration and management [PDF]

, 2010
The area of Swedish wet meadows has decreased drastically during the last century due to cultivation and abandonment. During the same time the meadow bird fauna have changed considerably.
