Anthony Mathiron, our former post-doc researcher, published his last data collected at LEAP in the Belgian Journal of Zoology, a completely free access journal managed by the Royal Belgian Zoological Society. This article is entitled : ” Water-borne cortisol levels show individuality and predict bold/shy behaviors in the self-fertilizing fish Kryptolebias marmoratus”. It is the…

3rd Joint Congress on Evolutionary Biology
The 3rd Joint Congress on Evolutionary Biology was held in Montreal in July 2024. It is a huge scientific conference (17 sessions in parallel), regrouping European and North American Evolutionary Biology Societies every 4 years. Justine Bélik and Frédéric Silvestre presented their researches on the mangrove rivulus during the special symposium on Adaptive Epigenetics. For…
A new post-doc researcher at LEAP !
We are happy to welcome Dr Noëmie Guirandy as a post-doc researcher in the rivulus team. Noëmie has recently been graduated from the University of Aix-Marseille after a dissertation on the reprotoxicity of gamma irradiation on zebrafish. She will be working on long-term effects of pollutants on the mangrove rivulus and will initiate an evolutionary…
New FNRS project at LEAP
We are pleased to announce that the research project entitled “Epigenome stability in mangrove rivulus” has been funded by FNRS. It aims to assess the stability of DNA methylation over time in a highly homozygous and isogenic population of the mangrove rivulus, Kryptolebias marmoratus. It will address two major limitations of ecoepigenetic studies. Firstly, it…
A field expedition in the mangrove of Belize
Version français en bas de page In May 2023, Justine Belik (young teaching assistant), Ivan Blanco (FRIA doctoral researcher) and myself (Frédéric Silvestre – professor) travelled to Belize, a small Central American country, to work on our favorite model fish: the mangrove rivulus. This killifish averages 3cm in adult size and is found exclusively in…
New publication about the insecticide permethrin
Our post-doc researcher Anthony Mathiron just published a research article in Aquatic Toxicology about the immediate and delayed effects of the insecticide permethrin on our fish model, the mangrove rivulus. This species is becoming a great model choice for ecotoxicology studies and the roles of epigenetics, showing a naturally very low level of genetic diversity….
Documentary about the mangrove rivulus
LEAP has published on its youtube channel a documentary of 29 minutes about the mangrove rivulus and the field work in Belize and Florida in 2019. It was a part of the PhD thesis of Valentine Chapelle during which we explored the mangroves in these two regions of the world. Please watch the video and…
LEAP welcomes Dr Sofia Consuegra
Dr Sofia Consuegra from the University of Swansea, Wales, visited our laboratory the 14th of March, as a jury member of Valentine Chapelle’s thesis. Dr Consuegra works on the mangrove killifish, among other species, and investigates epigenetic mechanisms, very close to what we’re doing. It was great opportunity to start future collaborations.
Valentine is a PhD !
We are happy to announce that our PhD student Valentine Chapelle has successfully passed her public PhD defence at UNamur, the 14th of March 2023. She explained to a broad public the epigenetic and behavioral variability among four natural populations of mangrove rivulus, along a genetic diversity gradient. Thank you to all the jury members…
New article in Aquatic Toxicology
Our new research article is now online in Aquatic Toxicology. It investigates the effects of methylmercury exposure in early life stages of mangrove rivulus fish at behavioral, gene expression and methylation levels. Congrats to Valentine Chapelle for her work! This article is a part of her PhD thesis. https://authors.elsevier.com/c/1gias,3oDQuOF4
