Seasonality alters drivers of soil enzyme activity in subalpine grassland soil undergoing climate change

Alexandre Buttler, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

In mountain ecosystems with marked seasonality, climate change can affect various processes in soils, potentially modifying long-term key soil services via change in soil organic carbon (C) storage. Based on a four-year soil transplantation experiment in S ...

Climate change effects on the stability and chemistry of soil organic carbon pools in a subalpine grassland

Alexandre Buttler, Bjorn Jozef Maria Robroek, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

Mountain soils stock large quantities of carbon as particulate organic matter that may be highly vulnerable to climate change. To explore potential shifts in soil organic matter (SOM) form and stability under climate change (warming and reduced precipitati ...

Loss of testate amoeba functional diversity with increasing frost intensity across a continental gradient reduces microbial activity in peatlands

Alexandre Buttler, Vincent Eric Jules Jassey, Luca Bragazza, Bjorn Jozef Maria Robroek, Constant Signarbieux, Robert Thomas Edmund Mills

Soil microbial communities significantly contribute to global fluxes of nutrients and carbon. Their response to climate change, including winter warming, is expected to modify these processes through direct effects on microbial functions due to osmotic str ...

Long-term organic carbon turnover rates in natural and semi-natural topsoils

Robert Thomas Edmund Mills

We combined published and new radiocarbon and ancillary data for uncultivated topsoils (typically 15 cm depth), to make two databases, one for the United Kingdom (133 sites), and one global (114 sites). Forest topsoils are significantly higher in radiocarb ...

Winter ecology of a subalpine grassland: Effects of snow removal on soil respiration, microbial structure and function

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills

Seasonal snow cover provides essential insulation for mountain ecosystems, but expected changes in precipitation patterns and snow cover duration due to global warming can influence the activity of soil microbial communities. In turn, these changes have th ...

Tropical soils degraded by slash-and-burn cultivation can be recultivated when amended with ashes and compost

Alexandre Buttler, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Justine Marie Gay des Combes

In many tropical regions, slash-and-burn agriculture is considered as a driver of deforestation; the forest is converted into agricultural land by cutting and burning the trees. However, the fields are abandoned after few years because of yield decrease an ...

Evaluation of Dissolved Organic Carbon as a Soil Quality Indicator in National Monitoring Schemes

Robert Thomas Edmund Mills

Background: Monitoring the properties of dissolved organic carbon (DOC) in soil water is frequently used to evaluate changes in soil quality and to explain shifts in freshwater ecosystem functioning. Methods: Using >700 individual soils (0-15 cm) collected ...

Diminished soil functions occur under simulated climate change in a sup-alpine pasture, but heterotrophic temperature sensitivity indicates microbial resilience

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

The pressure of climate change is disproportionately high in mountainous regions, and small changes may push ecosystem processes beyond sensitivity thresholds, creating new dynamics of carbon and nutrient cycling. Given that the rate of organic matter deco ...

Vascular plant-mediated controls on atmospheric carbon assimilation and peat carbon decomposition under climate change

Interactive effects of depth and temperature on CH4 and N2O flux in a shallow podzol

Robert Thomas Edmund Mills

Measuring and modelling the efflux of greenhouse gases from soils is crucial for gauging ecosystem responses to climate and land-use change, and potential contributions and feedbacks to gas emissions. Upland soils with high amounts of organic matter can pr ...

Seasonal influence of climate manipulation on microbial community structure and function in mountain soils

Alexandre Buttler, Bjorn Jozef Maria Robroek, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

Microbial communities drive soil organic matter (SOM) decomposition through the production of a variety of extracellular enzymes. Climate change impact on soil microbial communities and soil enzymatic activities can therefore strongly affect SOM turnover, ...

Slash-and-burn agriculture and tropical cyclone activity in Madagascar: Implication for soil fertility dynamics and corn performance

Alexandre Buttler, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Thomas Guillaume, Justine Marie Gay des Combes

On the western coast of Madagascar, the dry tropical forest of Kirindy may disappear in the next 50 years because of its rapid conversion into agricultural land by slash-and-burn cultivation. The slash-and-burn fields are cultivated during 3 years in avera ...

Social Integrating Robots Suggest Mitigation Strategies for Ecosystem Decay

Francesco Mondada, Robert Thomas Edmund Mills, Frank Bonnet, Rafael Botner Barmak

We develop here a novel hypothesis that may generate a general research framework of how autonomous robots may act as a future contingency to counteract the ongoing ecological mass extinction process. We showcase several research projects that have underta ...

Bio-Hybrid Systems for Ecosystem Level Effects

Francesco Mondada, Robert Thomas Edmund Mills, Jean-Louis Deneubourg, Robert Matthew Mills, Rafael Botner Barmak, Matthieu Jean-Michel Philippe Broisin

In a time marked by ecological decay and by the perspective of a severe backlash of this ecosystem decay and climate devastation onto human society, bold moves that employ novel technology to counteract this decline are required. We present a novel concept ...

Peatland vascular plant functional types affect methane dynamics by altering microbial community structure

Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills

Peatlands are natural sources of atmospheric methane (CH4), an important greenhouse gas. It is established that peatland methane dynamics are controlled by both biotic and abiotic conditions, yet the interactive effect of these drivers is less studied and ...

Sustained impact of drought on wet shrublands mediated by soil physical changes

Robert Thomas Edmund Mills

Projected climate warming may substantially increase carbon emissions from wet organic soils, contributing to a positive feedback between the terrestrial carbon cycle and climate change. Evidence suggests that in these soils the stimulation of soil respira ...

Freeze-thaw cycles simultaneously decrease peatland photosynthetic carbon uptake and ecosystem respiration

Alexandre Buttler, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Constant Signarbieux, Robert Thomas Edmund Mills

Decreasing snow cover in winter resulting from climate warming increases the incidence of freeze-thaw cycles (FTCs) in many ecosystems, including peatlands. As peatland ecosystems form a globally significant long-term carbon storage, understanding the effe ...
