Epigenome stability in mangrove rivulus - F. Silvestre

FNRS Research Credit associated to the PhD thesis of Justine Bélik: assess the stability of DNA methylation over time in a highly homozygous and isogenic population of the mangrove rivulus, Kryptolebias marmoratus. Two major limitations of ecoepigenetic studies will be addressed: the degree of autonomy of epigenetic variation based on genetic variation as well as the stability of epigenetic variation at the population level.

MAPPY - Multisectoral analysis of climate and land use change impacts on pollinators, plant diversity and crops yields – N. Dendoncker

The objective of this project is to study quantitatively the feedback processes linking pollinators, plant diversity and crop yields in the framework of climate and land use changes. The response of agricultural yields to climate change is critically dependent on these feedbacks that until now remain largely unexplored. In order to fill this gap, we will focus on studying interactions between three main sectors: biodiversity/nature conservation, forestry and agriculture. Within agriculture, the emphasis will be put on three sub-sectors: fruit crops, food/fodder crops and energy crops. We will use diverse types of crop and vegetation models to estimate the impacts of climate change on each studied sector in several case study regions in Europe. The study will be undertaken with local stakeholders, who will identify most relevant topics to be addressed by the consortium. The interdependencies between the sectors will be analysed through the dynamics of land use and land cover on the one hand and dynamics of pollinator communities on the other hand.

EDEN - J. Yans

Collaboration with the University of Montpellier on a new project financed by the ANR (Agence nationale de la recherche, France): Life during past super-warm climate events - Evolutionary Dynamics of Early EoceNe mammals from Southwestern France (EDEN).

The epigenetic origin of behavioural traits variability in a self-fertilizing fish: the mangrove rivulus - F. Silvestre

One of the greatest challenges in evolutionary biology is to determine how epigenetic mechanisms contribute to phenotypic variability, on which selection can act. The general objective of the present project is to explore the extent to which epigenetic polymorphism contributes to repeatable and predictable among-individual differences in behaviour (individuality) in the self-fertilizing fish mangrove rivulus, Kryptolebias marmoratus. It is intimately connected to Valentine Chapelle’s thesis. (2020-2021, 2021-2022)

The evolutionary enigma of a mixed-mating system in a self-fertilizing vertebrate, Kryptolebias marmoratus - F. Silvestre

PhD thesis of Ivan Blanco to study the mating system of the only self-fertilising vertebrate, the mangrove rivulus Kryptolebias marmoratus. In this species, hermaphrodites can either self-fertilise or outcross with a male. The thesis aims at identifying how and why different populations favour different rates of males and outcrossing. First, the mechanisms of temperature-dependant sex determination in this species will be investigated, followed by identification of the advantages that outcrossing populations might benefit from.

GETREAL - Incorporating spatial and seasonal variability in community sensitivity into chemical risk assessment - F. De Laender

GETREAL is an international project, funded by Cefic’s LRI, aimed at understanding how spatial variability of community composition influences resistance and resilience against global change effects on coexistence and ecosystem function. It will incorporate stressor effects on resource utilization traits in bioenergetic models to make theoretical predictions. In this project, Frederik De Laender (URBE, Biology) collaborates with the universities of Landau (Ralf Schäfer, Martin Schmidt-Entling) and Wageningen (Paul Van den Brink) to investigate how spatial variability in community composition, as inferred from decades' worth of biomonitoring data, map to spatial variability of community vulnerability. It will further include a small number of dedicated experiments with freshwater diatom communities to test some of the model’s assumptions. In collaboration with the university of Sheffield (Lorraine Maltby) the implications of the findings for the conservation of ecosystem services will be assessed. (2019-2021)

FIRST Spin-Off "AMMIB" and Project POC "Aedes" - K. Van Doninck & J. Marescaux

The implementation of EU legislation concerning ecosystems and biodiversity most often necessitates biological inventories. Morphological identifications for such species’ lists need skilled expertise, considerable time and money and may be inaccurate in describing hybrid, cryptic or exotic species. We apply the innovative method of environmental DNA (eDNA): organisms interact with their environment and leave behind traces of DNA. A simple water sample allows then a rapid determination of the species present. eDNA is a powerful tool for biodiversity monitoring.
