The effects of previous summer drought and fertilization on winter non-structural carbon reserves and spring leaf development of downy oak saplings

It is still unknown whether the previous summer season drought and fertilization will affect the winter non-structural carbohydrate (NSC) reserves, spring leaf development, and mortality of trees in the next year. We, therefore, conducted an experiment wit ...

Responses of plant leaf economic and hydraulic traits mediate the effects of early- and late-season drought on grassland productivity

Alexandre Buttler, Pierre Rémi Mariotte, Constant Signarbieux, Amarante Vitra, Claire Emilie Deléglise, Lia Aimée Marie-Joe Lamacque

Drought can occur at different times during the grassland growing season, likely having contrasting effects on forage production when happening early or later in the season. However, knowledge about the interacting effects of the timing of drought and the ...

Hydrological and Geomorphological Significance of Riparian Vegetation in Drylands

Paolo Perona

Drylands are regions encompassing hyperarid, arid, semiarid, or subhumid climatic conditions (see also Chap. 1). They include cold and warm subtropical deserts, savannas, and the Mediterranean environments. Our focus here is on warm drylands, which are gen ...

Snowmelt-Driven Trade-Offs Between Early and Late Season Productivity Negatively Impact Forest Carbon Uptake During Drought

Ernesto Trujillo Gomez

uture projections of declining snowpack and increasing potential evaporation are predicted to advance the timing of snowmelt in mountain ecosystems globally with unknown implications for snowmelt‐driven forest productivity. Accordingly, this study combined ...

Experimental warming interacts with soil moisture to discriminate plant responses in an ombrotrophic peatland

Alexandre Buttler, Pierre Rémi Mariotte, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Cédric Pochelon

QuestionA better understanding of the response of Sphagnum mosses and associated vascular plants to climate warming is relevant for predicting the carbon balance of peatlands in a warmer world. Open-top chambers (OTCs) have been used to investigate the eff ...

Modeling Soil–Plant Dynamics: Assessing Simulation Accuracy by Comparison with Spatially Distributed Crop Yield Measurements

Sara Bonetti

Coupling hydrological models with plant physiology is crucial to capture the feedback mechanisms occurring within the soil–plant–atmosphere continuum. However, the ability of such models to describe the spatial variability of plant responses to different e ...

Transient response of Salix cuttings to changing water level regimes

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

Sustainable water management requires an understanding of the effects of flow regulation on riparian ecomorphological processes. We investigated the transient response of Salix viminalis by examining the effect of water-level regimes on its above-ground an ...

Iron Chloride-Catalyzed Three-Component Domino Sequences: Syntheses of Functionalized α-Oxy-N-acylhemiaminals and α-Oxyimides

Jieping Zhu

The iron(III) chloride-multicatalyzed dioxygenation of enamides with TEMPO in the presence of alcohols has been developed. This multicomponent domino process affords efficient new strategies for the synthesis of alpha-oxy-N-acylhemi-aminals or alpha-oxyimi ...

Evidence and modelling biomass selection by floods in a riverbed

Paolo Perona, Benoît Crouzy

Riparian and in-bed vegetation growth and erosion dynamics are strongly coupled with river hydrologic and morphodynamic processes. Many field observations documented the engineering role of vegetation and its contribution to build, stabilize and control er ...

An experimental comparison of silica gel and quartz sand grains as sediment media for growing vegetation at the laboratory scale

Paolo Perona, Peter Molnar, Zhe Jiang

In this technical note we compare silica gel grains and quartz sand as sediment media for vegetation root growth in laboratory experiments for ecohydrology and ecohydraulics. Silica gel grains become quite transparent when saturated with water. This would ...
