Drought-induced shifts in plants traits, yields and nutritive value under realistic grazing and mowing managements in a mountain grassland

Alexandre Buttler, Thomas Spiegelberger, Constant Signarbieux, Claire Emilie Deléglise

Extreme drought events can dramatically impact grassland ecosystems, causing potential loss of forage production for livestock in temperate grasslands. However, knowledge of drought effects on forage production, nutritive value and plant community stabilit ...

Effects of hydropeaking waves offsets on growth performances of juvenile Salix species

Alexandre Buttler, Pascal Turberg, Paolo Perona, Lorenzo Gorla, Constant Signarbieux

Hydropower production and other human activities change the natural flow regime of rivers (e.g., hydropeaking effects), in turn, impacting the riparian environment. Here we present an experiment conceived to investigate the response of forced offsets in wa ...

An unexpected role for mixotrophs in the response of peatland carbon cycling to climate warming

Alexandre Buttler, Enrique Lara, Edward Mitchell, Bertrand Fournier, Luca Bragazza, Robert Thomas Edmund Mills, Constant Signarbieux, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

Mixotrophic protists are increasingly recognized for their significant contribution to carbon (C) cycling. As phototrophs they contribute to photosynthetic C fixation, whilst as predators of decomposers, they indirectly influence organic matter decompositi ...

Experimental response of Salix cuttings to different flow regimes due to human activities

Alexandre Buttler, Pascal Turberg, Paolo Perona, Lorenzo Gorla, Constant Signarbieux

Non-stomatal limitations of photosynthesis in grassland species under artificial drought in the field

Constant Signarbieux

As drought stress is expected to occur more frequently in future climate in central Europe, survival and productivity of grassland species are an important issue. Non-stomatal limitation processes related to the drought-stress inhibition of photosynthesis ...

Competitive advantage of Rumex obtusifolius L. might increase in intensively managed temperate grasslands under drier climate

Constant Signarbieux

Climate models predict decreasing amounts of precipitation for future summers in Switzerland. Since grasslands cover about one quarter of the area, severe consequences might be expected for Swiss agriculture, ranging from loss of grassland productivity to ...
