Seasonal variability of groundwater level effects on the growth of Carex cinerascens in lake wetlands

Alexandre Buttler, Luca Bragazza, Pierre Rémi Mariotte, Wenjuan Feng, Mathieu Raymond Santonja

Groundwater level is crucial for wetland plant growth and reproduction, but the extent of its effect on plant growth can vary along with changed precipitation and temperature at different seasons. In this context, we investigated the effect of two groundwa ...

Effects of Sphagnum Leachate on Competitive Sphagnum Microbiome Depend on Species and Time

Alexandre Buttler, Luca Bragazza, Constant Signarbieux, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Samuel Thomas Gabriel Hamard

Plant specialized metabolites play an important role in soil carbon (C) and nutrient fluxes. Through anti-microbial effects, they can modulate microbial assemblages and associated microbial-driven processes, such as nutrient cycling, so to positively or ne ...

Plastic and genetic responses of a common sedge to warming have contrasting effects on carbon cycle processes

Luca Bragazza, Richard David Bardgett, Constant Signarbieux, Thomas William Nicholas Walker

Climate warming affects plant physiology through genetic adaptation and phenotypic plasticity, but little is known about how these mechanisms influence ecosystem processes. We used three elevation gradients and a reciprocal transplant experiment to show th ...

Dispersal limitations and historical factors determine the biogeography of specialized terrestrial protists

Enrique Lara, Edward Mitchell, Bertrand Fournier, Luca Bragazza, Mariusz Lamentowicz

Recent studies show that soil eukaryotic diversity is immense and dominated by micro-organisms. However, it is unclear to what extent the processes that shape the distribution of diversity in plants and animals also apply to micro-organisms. Major diversif ...

Environmental and taxonomic controls of carbon and oxygen stable isotope composition in Sphagnum across broad climatic and geographic ranges

Luca Bragazza, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek

Rain-fed peatlands are dominated by peat mosses (Sphagnum sp.), which for their growth depend on nutrients, water and CO2 uptake from the atmosphere. As the isotopic composition of carbon (C-12(,)13) and oxygen (O-16(,)18) of these Sphagnum mosses are affe ...

Interaction of compost additives with phosphate solubilizing rhizobacteria improved maize production and soil biochemical properties under dryland agriculture

Alexandre Buttler, Luca Bragazza, Muhammad Riaz, Bjorn Jozef Maria Robroek, Muhammad Saleem Arif, Muhammad Ashraf

Dry land soils from the Indo-Gangetic plains are inherently poor in organic matter content and phosphorus (P). Amendment of these soils with P-enriched compost, together with P solubilizing rhizobacterial (PSR) inoculation has been suggested to improve pla ...

Nitrogen-enriched compost application combined with plant growth-promoting rhizobacteria (PGPR) improves seed quality and nutrient use efficiency of sunflower

Alexandre Buttler, Luca Bragazza, Muhammad Riaz, Muhammad Saleem Arif

Ecological benefits associated with plant growth-promoting rhizobacteria (PGPR) inoculants offer a promising integrated nutrient management option to counteract plant nitrogen (N) deficiency. We performed field experiments to evaluate the effect of integra ...

Impacts of regional climatic fluctuations on radial growth of Siberian and Scots pine at Mukhrino mire (central-western Siberia)

Luca Bragazza, Guillaume Blanchet, Baptiste Calliari

Ring width (TRW) chronologies from Siberian (Pinus sibirica) and Scots (Pinus sylvestris) pine trees were sampled at Mukhrino - a large mire complex in central-western Siberia - to evaluate the impacts of hydroclimatic variability on tree growth over the l ...

Taxonomic and functional turnover are decoupled in European peat bogs

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

In peatland ecosystems, plant communities mediate a globally significant carbon store. The effects of global environmental change on plant assemblages are expected to be a factor in determining how ecosystem functions such as carbon uptake will respond. Us ...
