All climatic scenarios predict that both temperatures and their variations should increase in the forthcoming decades, with side-effects on plant growth and phenology (Hollister et al., 2005) that should ultimately affect interactions between species (Williams et al., 2007). Climate change effects are especially severe in aquatic plants (i.e. macrophytes) (Lacoul & Freedman, 2006), which are both a resource and a habitat for a diversity of organisms (Keddy, 2010). Yet, its consequences for the dynamics of macrophyte communities received little attention so far. Moreover, one challenge in ecology is understanding the mechanisms and extent of thermal stress that influence plant biodiversity and community structure.
At the species scale, previous studies demonstrated that plant individuals display opposite foliar trait responses to competition (Bittebiere et al., 2012) and thermal stress (Shah & Paulsen, 2003). For instance, in terrestrial plants, competition and thermal stress respectively induce an increase (Bittebiere et al., 2012) or a decrease in leaf area (Shah & Paulsen, 2003), likely affecting their photosynthetic efficiency and thus individual biomass production. Overall, this literature knowledge raises the question of how plant individuals can simultaneously cope with plant-plant interactions and thermal stress based on metabolic and morphological responses, and how it ultimately affects their performances.
In this context, the hired post-doctoral fellow will have to study the morphological response to rising water temperatures in aquatic plant species from the Iles Kerguelen (sub-Antarctic region), in a context of plant-plant interactions. This study will mostly rely on experimental approaches.


- Design experimentations under controlled conditions
- Perform experimentations on plants under controlled conditions
- Measure plant traits
- Statistically analyze the data
- Write the manuscript to publish the results.


The post-doctoral fellow should have:
- some experience in experimental ecology and trait measurement on plants
- already published paper(s) in the field of functional ecology in the context of climate changes

Work Context

The post-doctoral fellow will be part of the LEHNA lab (in Villeurbanne, France; https://umr5023.univ-lyon1.fr/) and of the BAH team (https://umr5023.univ-lyon1.fr/equipes-de-recherche/bah).
