Trophic interactions and feedbacks maintain intact and degraded states of Hawaiian tropical forests

open access: yesEcosphere, 2022
Feedbacks within ecosystems can lead to internal reinforcement of the current state providing ecosystem resilience. Often, multiple biotic interactions across trophic levels play a role in such feedbacks, yet these are generally studied independently ...

Tiger reefs: Self‐organized regular patterns in deep‐sea cold‐water coral reefs

open access: yesEcosphere, 2023
Complexity theory predicts that self‐organized, regularly patterned ecosystems store more biomass and are more resilient than spatially uniform systems.

Evaluer à l’école maternelle : des pratiques sexuées ?

open access: yesRevue GEF, 2023
Notre étude s’intéresse à la production de feedbacks (positifs et négatifs) par deux enseignant·es d’école maternelle (un homme et une femme) en fonction du sexe des élèves lors de l’activité en classe et de l’activité physique et sportive.

Feedbacks between protistan single-cell activity and bacterial physiological structure reinforce the predator/prey link in microbial foodwebs

open access: yesFrontiers in Microbiology, 2014
The trophic interactions between bacteria and their main predators, the heterotrophic nanoflagellates (HNF), play a key role in the structuring and functioning of aquatic microbial food webs.

Exploring the Impacts of Seagrass on Coupled Marsh-Tidal Flat Morphodynamics

open access: yesFrontiers in Environmental Science, 2018
Intertidal coastal environments are prone to changes induced by sea level rise, increases in storminess, temperature, and anthropogenic disturbances. It is unclear how changes in external drivers may affect the dynamics of low energy coastal environments

A GIS-toolbox for a landscape structure based Wind Erosion Risk Assessment (WERA)

open access: yesMethodsX
The landscape structure influences the local wind field by lowering the wind speed and thus reducing the wind erosion risk. An important parameter is the height of each landscape element, as this determines the length of wind protection behind it ...

Génération et régulation d’émotions académiques chez les étudiants

open access: yesQuestions Vives
In a context where emotions and cognition are inseparably linked (Fischer, 2020), this research examines the impact of feedback delivered through the FB4You application on students’ emotions and their regulation at the University of Liège.

Understanding the decline and resilience loss of a long-lived social-ecological system: insights from system dynamics

open access: yesEcology and Society, 2017
Collapse of social-ecological systems (SESs) is a common process in human history. Depletion of natural resources, scarcity of human capital, or both, is/are common pathways toward collapse.

Interactions with soil fungi alter density dependence and neighborhood effects in a locally abundant dipterocarp species

open access: yesEcology and Evolution, 2022
Seedling recruitment can be strongly affected by the composition of nearby plant species. At the neighborhood scale (on the order of tens of meters), adult conspecifics can modify soil chemistry and the presence of host microbes (pathogens and mutualists)

Étudier la conversation pour mieux comprendre le langage

open access: yesTIPA. Travaux interdisciplinaires sur la parole et le langage, 2023
This chapter deals with the linguistic manifestations of conversation. For a long time, linguists have been interested in the levels of oral language (phonology, lexicon, syntax, discourse) separately, particularly based on prepared and non-interactive ...
