Arbuscular mycorrhizal fungi reduce the differences in competitiveness between dominant and subordinate plant species

Alexandre Buttler, Pierre Rémi Mariotte, Thomas Spiegelberger, Aurélie Thébault, Claire Meugnier

In grassland communities, plants can be classified as dominants or subordinates according to their relative abundances, but the factors controlling such distributions remain unclear. Here, we test whether the presence of the arbuscular mycorrhizal (AM) fun ...

Subordinate plant species impact on soil microbial communities and ecosystem functioning in grasslands: Findings from a removal experiment

Alexandre Buttler, Pierre Rossi, Pierre Rémi Mariotte, Charlotte Vandenberghe, Richard David Bardgett, Claire Meugnier

Despite their low relative abundance, subordinate plant species may have larger impacts on ecosystem functioning than expected, but their role in plant communities remains poorly understood. The aim of this study was to test how subordinate plant species i ...

Functionalization of Open Two-Dimensional Metal-Organic Templates through the Selective Incorporation of Metal Atoms

Klaus Kern, Sebastian Stepanow, Christopher Seiji Kley

Surface-confined molecular networks can serve as templates to steer the adsorption and organization of secondary ligands, metal atoms, and clusters. Here, the incorporation of Ni atoms and clusters into open two-dimensional robust metal-organic templates s ...

Effects of Subordinate Plant Species in Plant and Soil Community Structure and Ecosystem Functioning

Pierre Rémi Mariotte

The relevance of biodiversity to human health is an increasing international political issue as it causes concern for ethical and aesthetic reasons, but also has a strong impact on ecosystem properties and ecological goods and services utilised by humanity ...

Over-expression of PHO1 in Arabidopsis leaves reveals its role in mediating phosphate efflux

Michaël Bensimon, Charles Vidoudez

P>Inorganic phosphate (Pi) homeostasis in multi-cellular eukaryotes depends not only on Pi influx into cells, but also on Pi efflux. Examples in plants for which Pi efflux is crucial are transfer of Pi into the xylem of roots and release of Pi at the peri- ...

Long-term effects of grazing exclusion on aboveground and belowground plant species diversity in a steppe of the Loess Plateau, China

Background and aims - Livestock grazing exclusion was widely used to manage degraded grassland ecosystems, but little is known on the effects of long-term grazing exclusion on aboveground and belowground species diversity of the steppe vegetation in China. ...

Long-term dynamics of aboveground fungal communities in a subalpine Norway spruce forest under elevated nitrogen input

Rita Bütler Sauvain, François Gillet, Simon Egli

As anthropogenic N deposition has been suspected to be the main reason for the decline of macromycetous sporocarp production in forest ecosystems, various N-fertilization experiments were started in the mid 1990s. The dynamics of ectomycorrhizal (root-inha ...

How Does Plant Diversity Affect Soil Aggregate Stability and Erosion Processes in Disturbed Alpine Ecosystems?

Plant species diversity is hypothesized to be among the most relevant factors for enhancing soil stability in disturbed sites at high elevation. Because a more diverse plant community may comprise a high number of plant species of different growth forms, p ...

Heatwave 2003: high summer temperature, rather than experimental fertilization, affects vegetation and CO2 exchange in an alpine bog

Luca Bragazza

Nitrogen and phosphorus were added experimentally in a bog in the southern Alps. It was hypothesized that alleviating nutrient limitation will increase vascular plant cover. As a consequence, more carbon will be fixed through higher rates of net ecosystem ...

The complement of protein kinases of the microsporidium Encephalitozoon cuniculi in relation to those of Saccharomyces cerevisiae and Schizosaccharomyces pombe

BACKGROUND: Microsporidia, parasitic fungi-related eukaryotes infecting many cell types in a wide range of animals (including humans), represent a serious health threat in immunocompromised patients. The 2.9 Mb genome of the microsporidium Encephalitozoon ...
