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
Ivan Blanco is in Maryland !
After a long waiting time due to the Covid crisis (postponed since summer 2020), our PhD student Ivan Blanco has finally arrived in Maryland to work with Professor Eric S. Haag during 2 months. He aims to use microinjection techniques to knock-down some genes in the early embryo of the mangrove rivulus. He will gain…
New article in Epigenetics
A new article has been published in the specialised journal “Epigenetics” in collaboration with our partner Anirhudda Chatterjee from the University of Otago. It the last part of the PhD thesis of Anne-Sophie Voisin who aimed to investigate the long-term effects of an early life stage exposure to the endocrine disruptor ethinyl estradiol (EE2) in…
Visit of Ryan Earley in Namur
Last week, we were very glad to welcome our collaborator from the University of Alabama, Dr Ryan Earley, for a 4 days visit in Namur. Ryan is the world specialist of the mangrove rivulus and has been on the field in Belize with us to study this fish population. It was first time Ryan visited…
Ivan Blanco is our new PhD student
Congratulations to Ivan Blanco who will work in LEAP for the next four years to achieve a PhD thesis on the mangrove rivulus. Ivan just obtained a grant from the FNRS (FRIA) to work on the mating system of the self-fertilizing fish mangrove rivulus. In this species, hermaphrodites can either self-fertilize or outcross with a…
