A rainfall manipulation experiment was conducted over a two-year period on two semi-natural grassland sites, in order to determine the effects of drought on both forage production (dry matter and nutritive value) and plant-soil relationships. Water stress ...

It is generally accepted that resource availability shapes the structure and function of many ecosystems. Within the soil-plant-atmosphere (SPA) system, resource availability fluctuates in space and time whereas access to resources by individuals is furthe ...

Short-term effects of biochar on grapevine fine root dynamics and arbuscular mycorrhizae production

Application of biochar to the soil is globally recognised as a means to improve soil structure and fertility, increase carbon sequestration, enhance crop production and mitigate climate change. However, although the fine root system is fundamental for plan ...

Characterization of carbon dioxide concentrating chemolithotrophic bacterium Serratia sp ISTD04 for production of biodiesel

Edgard Gnansounou, Manish Kumar

Proteomics and metabolomics analysis has become a powerful tool for characterization of microbial ability for fixation of Carbon dioxide. Bacterial community of palaeoproterozoic metasediments was enriched in the shake flask culture in the presence of NaHC ...

Persistent high temperature and low precipitation reduce peat carbon accumulation

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, Bjorn Jozef Maria Robroek, Remy Jean Henry Albrecht

Extreme climate events are predicted to become more frequent and intense. Their ecological impacts, particularly on carbon cycling, can differ in relation to ecosystem sensitivity. Peatlands, being characterized by peat accumulation under waterlogged condi ...

Environmental drivers of carbon and nitrogen isotopic signatures in peatland vascular plants along an altitude gradient

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Luca Bragazza

Peatlands are important sinks of atmospheric carbon (C) that, in response to climate warming, are undergoing dynamic vegetation succession. Here we examined the hypothesis that the uptake of nutrients by different plant growth forms (PGFs) is one key mecha ...

Northern peatlands are large repositories of carbon. Peatland vascular plant community composition has been functionally associated to a set of biogeochemical processes such as carbon cycling. Yet, we do not fully understand to what extent vascular plant f ...

Linking soil microbial communities to vascular plant abundance along a climate gradient

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Richard David Bardgett

The ongoing expansion of shrub cover in response to climate change represents a unique opportunity to explore the link between soil microbial communities and vegetation changes. This link is particularly important in peatlands where shrub expansion is expe ...

Phytoremediation of polluted soils: hype, hope and facts

Jean-Paul Schwitzguebel

Different plant species, ecotypes, varieties or cultivars can be selected, tailored and harnessed for the remediation of polluted soils, sites and brownfields, as well as for the phytotreatment of domestic or industrial wastewater. Several approaches are p ...
