Temporal Variability of Precipitation and Biomass of Alpine Grasslands on the Northern Tibetan Plateau

Remote Sensing, 2019
The timing regimes of precipitation can exert profound impacts on grassland ecosystems. However, it is still unclear how the peak aboveground biomass (AGBpeak) of alpine grasslands responds to the temporal variability of growing season precipitation (GSP)

From low to high elevations, flowers adapt traits and phenology to climate, but phenology‐trait relationships weak

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Flowering phenology is central to plant reproductive success and can relate to morphological traits such as size and quality of flowers, but phenology–trait associations of flowers remain unclear.

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.

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.

Shrubs inhibit plant diseases by intercepting light in alpine meadows

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change is disproportionately impacting mountain ecosystems, leading to widespread shrub expansion into alpine meadows. Shrub encroachment alters the albedo, carbon budget and warming rate in alpine grasslands, but it remains challenging to predict how shrub ...

Biomass allocation and productivity–richness relationship across four grassland types at the Qinghai Plateau

Ecology and Evolution, 2020
Aboveground biomass (AGB) and belowground biomass (BGB) allocation and productivity–richness relationship are controversial. Here, we assessed AGB and BGB allocation and the productivity–richness relationship at community level across four grassland ...

Fertilization influences overyielding through dominance of species with high specific leaf area in young tree mixtures

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In the context of anthropogenic eutrophication of the biosphere, understanding the impact of nutrient addition on plant diversity–productivity relationships remains a major challenge.

Anthropogenic nitrogen addition interrupts seasonal connectivity and structures of plant–pollinator networks

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...
