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 publication from Anthony Mathiron
Our new article has been written by our former post-doc researcher, Anthony Mathiron, and has been published in the excellent Environmental Toxicology and Pharmacology (IF 5.8). It looks at the use of the photomotor response test (PMR) in animals in the context of ecotoxicology. The PMR test can be used to observe the effects of…
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….
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 Download QR
Jury thesis in Corsica
Frédéric Silvestre spent two days in Bastia, Corsica, as the president of the jury for the evaluation of the PhD thesis of Ouafa El Idrissi, within a joint program from the Universities of Corse (Corte) and of Liège. This excellent thesis developped the sea urchin Paracentridus lividus as a bioindicator species to assess trace elements pollution…
Radio podcast on RTBF
