High-throughput isolation of anaerobic arsenic-transforming microorganisms

Arsenic (As) is a toxic metalloid that occurs naturally and is widely distributed in the environment. The inorganic compounds arsenite (As(III)) and arsenate (As(V)) are the most prevalent As species in the biosphere, the former being predominant in reduci ...

Drag reduction of flexible disks through vortex ring manipulation

Mrudhula Baskaran

Extreme weather events are increasing in frequency in recent years due to global climate change. These events damage infrastructure and pose an open challenge to engineers to design more weather-resistant infrastructure. As engineers, we turn to nature fo ...

Mechanisms of woody-plant mortality under rising drought, CO2 and vapour pressure deficit

Charlotte Grossiord

Drought-associated woody-plant mortality has been increasing in most regions with multi-decadal records and is projected to increase in the future, impacting terrestrial climate forcing, biodiversity and resource availability. The mechanisms underlying suc ...

Plant responses to rising vapor pressure deficit

Charlotte Grossiord

Recent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes including ...

Linking soil's volatilome to microbes and plant roots highlights the importance of microbes as emitters of belowground volatile signals

Richard Splivallo, Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra

Plants and microbes release a plethora of volatiles that act as signals in plant-microbe interactions. Characterizing soil's volatilome and microbiome might shed light on the nature of relevant volatile signals and on their emitters. This hypothesis was te ...

Impact of drought on the functioning of grassland systems

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra

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 ...

Use of Transient Measurements for Static Real-Time Optimization

Dominique Bonvin, Grégory François, Alejandro Gabriel Marchetti, Tafarel de Avila Ferreira

Modifier adaptation (MA) is a real-time optimization (RTO) method characterized by its ability to enforce plant optimality upon convergence despite the presence of model uncertainty. The approach is based on correcting the available model using gradient es ...

Optofluidics of plants

Demetri Psaltis, Jae-Woo Choi, Andreas Vasdekis

Optofluidics is a tool for synthesizing optical systems, making use of the interaction of light with fluids. In this paper we explore optofluidic mechanisms that have evolved in plants where sunlight and fluidic control combine to define most of the functi ...

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

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

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 ...

Tidal influence on soil conditions in an intertidal creek-marsh system

David Andrew Barry

To understand better how tides affect the soil conditions of salt marshes, pore-water flow in a modeled 3-D creek-marsh system was simulated under the influence of both monochromatic and spring-neap tides. In analyzing the simulation results, we examined s ...

Risk analysis in research environment

Thierry Meyer, Amela Groso, Aristide Ramondgwendé Ouédraogo

Available risk analysis techniques are well adapted to industry since they were developed for its purpose. All hazards met in industry are also present in research/academia (although quantities of some hazardous substances are smaller). Still, because of i ...
