A new publication from our former PhD student Anne-Sophie Voisin is now available in Journal of Proteomics. We showed that adult mangrove rivulus exposed during early life stages to an endocrine disrupting chemical (17-alpha-ethinylestradiol) present significant changes on the protein expression profile in brain, liver and gonads in adults, 5 months after the end of…

Valentine is our new PhD student
We’re proud to welcome Valentine Chapelle in our lab for the next 4 years. After a great MSc thesis on the mangrove rivulus heritability of personalities, Valentine successfully got a FRIA grant from FNRS. She will continue her work started during her master thesis and will evaluate the origin of epigenetic variability in natural populations…
New article about epigenetics in the mangrove rivulus
Our former post-doc researcher Alexandre Fellous has published the first data on histone methyltransferase (Kmt) and demethylase (Kdm) enzymes in our killifish model, the mangrove rivulus. This article has been published in the journal “Gene” and is a starting point to deeper analyze histone modifications during embryogenesis and the implication of epigenetic mechanisms in adaptation…
New article published on the effects of BMAA on the mangrove rivulus
Our two master students, Julie Hetru and Angèle Markay, published preliminary data during their master thesis under the supervision of Alessandra Carion. It is our first article related to behavioral effects of pollutant exposure (the natural neurotoxin BMAA -ß-N-methylamino-L-alanine) during fish development. It successfully used the mangrove rivulus as an ecotoxicological model to assess the…
ISBE conference 2018
Alessandra Carion and Frederic Silvestre attended the conference ISBE 2018 at Minneapolis, Minnesota, from August 11th to 16th. This conference is organized every other year by the International Society for Behavioral Ecology and bring together scientists working on animal behavior in a context of ecology and evolution. Alessandra presented few results obtained recently for her…
Ecobim conference in Bordeaux
This year, the conference Ecobim has been held at the University of Bordeaux (http://ecobim.ca/colloques/ecobim-2018/). This conference put together specialists in ecotoxicology from the french speaking countries, mainly France and Canada. Since 2017, Belgium is also participating, as well as 6 other countries. Frédéric Silvestre, Julie Hetru and Angèle Markey were present in Bordeaux. Julie gave…
New article published in Ecology and Evolution
A first article on our work on epigenetics in the mangrove rivulus has been published in the journal “Ecology and Evolution”. This article published by Alexandre Fellous depicts the DNA methylation profile of this fish, in adults and during embryogenesis. It also characterizes the main enzymes involved in this process. Altogether, our findings open the…
Anne-Sophie Voisin is PhD !
Our former PhD student Anne-Sophie Voisin has presented her thesis dissertation the 2nd of May. She was the first PhD student to work and to publish on our model fish species, the mangrove rivulus. She combined phenotypic, proteomic and epigenetic approaches to investigate the delayed effects in adults of an early life exposure to the…
Field trip to Florida
In January 2018, a team from our lab visited the Florida mangroves in order to sample the mangrove Rivulus in its natural habitat. Morgane, Victoria and Frederic travelled from as North as Emerson Point (Manatee County) to the Florida Keys. The main goal of this campaign is to assess the epigenetic variability within and among…
Mangrove Rivulus microhabitat
To spot the mangrove Rivulus, it’s important to first identify the microhabitat they live in. For that, a deep observation of the mangrove is needed. This fish mostly lives where the black and red mangroves are present, where there is a little of water (between 25 and 35 ppt), a lot of mud and leaf…
