From roots to canopy: Unraveling the influence of species diversity on tree water relations under warmer and drier climates

Eugénie Isabelle Mas

The worsening of drought events with rising air temperature alters tree water relations causing severe hydraulic impairments and widespread forest mortality. Mixing tree species with contrasting hydraulic traits could reduce forest vulnerability to extreme ...

Tree diversity reduces variability in sapling survival under drought

Charlotte Grossiord, Jingjing Liang

Enhancing tree diversity may be important to fostering resilience to drought-related climate extremes. So far, little attention has been given to whether tree diversity can increase the survival of trees and reduce its variability in young forest plantatio ...

Coupled carbon and nitrogen cycling regulates the cnidarian–algal symbiosis

Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker

Efficient nutrient recycling underpins the ecological success of cnidarian-algal symbioses in oligotrophic waters. In these symbioses, nitrogen limitation restricts the growth of algal endosymbionts in hospite and stimulates their release of photosynthates ...

Interactions between beech and oak seedlings can modify the effects of hotter droughts and the onset of hydraulic failure

Charlotte Grossiord, Eugénie Isabelle Mas, Janisse Deluigi, Margaux Clara Lou Didion-Gency

center dot Mixing species with contrasting resource use strategies could reduce forest vulnerability to extreme events. Yet, how species diversity affects seedling hydraulic responses to heat and drought, including mortality risk, is largely unknown. Using ...

Assessing the persistence of chalcogen bonds in solution with neural network potentials

Anne-Clémence Corminboeuf, Rubén Laplaza Solanas, Veronika Juraskova, Frédéric Célerse

Non-covalent bonding patterns are commonly harvested as a design principle in the field of catalysis, supramolecular chemistry, and functional materials to name a few. Yet, their computational description generally neglects finite temperature and environme ...

Spatio-temporal modeling of the crowding conditions and metabolic variability in microbial communities

Vassily Hatzimanikatis, Liliana Angeles Martinez

The metabolic capabilities of the species and the local environment shape the microbial interactions in a community either through the exchange of metabolic products or the competition for the resources. Cells are often arranged in close proximity to each ...

The genetic architecture of complex human traits at the dawn of genomic medicine

Olivier Noël Marie Naret

The focus of the work presented in this thesis is the exploration of the genetic architecture of complex human traits - at the dawn of genomic medicine. The underlying mechanisms explaining the enormously polygenic nature of most human complex traits are ...

Inventory of Problems: The Genesis of the Rotterdam Kunsthal by OMA/Rem Koolhaas, 1987-1992

Tibor Bonaventura Pataky

The Kunsthal in Rotterdam is a key work in the oeuvre of OMA/Rem Koolhaas that marks the threshold between the firmâ s architectural production of the decades before and after 1990. This doctoral thesis aims at a deeper and comprehensive understanding of ...

Reaction of DMS and HOBr as a Sink for Marine DMS and an Inhibitor of Bromoform Formation

Urs von Gunten

Recently, we suggested that hypobromous acid (HOBr) is a sink for the marine volatile organic sulfur compound dimethyl sulfide (DMS). However, HOBr is also known to react with reactive moieties of dissolved organic matter (DOM) such as phenolic compounds t ...

War of Words: The Competitive Dynamics of Legislative Processes

Patrick Thiran, Matthias Grossglauser, Victor Kristof

A body of law is an example of a dynamic corpus of text documents that are jointly maintained by a group of editors who compete and collaborate in complex constellations. Our goal is to develop predictive models for this process, thereby shedding light on ...

Intracellular competition for nitrogen controls dinoflagellate population density in corals

Anders Meibom, Stéphane Laurent Escrig, Maoz Fine, Thomas Krüger, Julia Marie Jeanne Yvonne Bodin, Maria-Evangelia Giovani

The density of dinoflagellate microalgae in the tissue of symbiotic corals is an important determinant for health and productivity of the coral animal. Yet, the specific mechanism for their regulation and the consequence for coral nutrition are insufficien ...

Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil

Alexandre Buttler, Pierre Rémi Mariotte, Mathieu Raymond Santonja, Lucas Georges Jean-Paul Freund

Aims Previous cover crop studies mainly focused on the links between plant uptake and soil fertility, and there is a clear knowledge gap regarding the role of microbes in these processes. Our aim was then to better understand the effects of plant mixtures ...

Les grands projets urbains entre global et local : une étude de cas comparative de Casablanca et de Genève à travers les logiques de marché et les résistances locales

Kamil Hajji

Globalization implies profound changes in territories that involve the emergence of major urban renewal projects. It has the effect of increasing competition between metropolises. In order to make a place for themselves in this increasingly competitive glo ...

Neural dynamics of the competition between grouping organizations

Michael Herzog, Ophélie Gladys Favrod, Einat Rashal

Neural dynamics of the competition between grouping organizations have been studied to a limited extent. The paradigms used so far confounded grouping operations with task demands, using explicit reports of the predominantly perceived organization and bias ...

Effects of Sphagnum Leachate on Competitive Sphagnum Microbiome Depend on Species and Time

Alexandre Buttler, Vincent Eric Jules Jassey, Luca Bragazza, Bjorn Jozef Maria Robroek, Constant Signarbieux, Samuel Thomas Gabriel Hamard

Plant specialized metabolites play an important role in soil carbon (C) and nutrient fluxes. Through anti-microbial effects, they can modulate microbial assemblages and associated microbial-driven processes, such as nutrient cycling, so to positively or ne ...

Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Alexandre Louis André Persat

Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morpholog ...

The important thing is not to win, it is to take part: What if scientists benefit from participating in research grant competitions?

Fabiana Visentin, Charles Chadi Ayoubi, Michele Pezzoni

“The important thing is not to win, it is to take part,” this famous saying by Pierre de Coubertin asserts that the value athletes draw from Olympic games lies in their participation in the event and not in the gold they collect during it. We find similar ...
