Science at UM [S02-ep05]: Invasive fish on the sensory analysis platform
This week on A l’UM la science, Rodolphe Gozlan, a researcher atISEM, talks to us about invasive species, particularly freshwater fish. In the second part of the program, Eric Picou gives us a tour of the sensory analysis platform at the Sciences pour l’œnologie laboratory. Finally, Sylvie Rapior will talk to us about the Mushroom and Autumn Plants Fair.
Today we tell you the story of a spectacular escape. We are in Paris in the 19th century. The capital is buzzing with its imperial status. Great explorations and colonization are opening France up to the world. Scientists, naturalists, and the general public are enthralled by the animal and plant species brought back from all corners of the world to fill museums and botanical gardens. At the National Museum of Natural History, a fish from North America is causing a stir because of its funny whiskers, which make it look like a cat. Just look like a cat? Not really, because like any self-respecting feline, the catfish is a lover of freedom that does not allow itself to be easily confined, and it is simply through the sewer system that this non-native species finally reaches the Seine. A century later, our escapee proves to be more invasive than it appeared, and this indomitable creature is now classified as a pest.
As you know, today we are talking about invasive species, and more specifically freshwater fish. Our guest is a researcher at the Institute of Evolutionary Sciences in Montpellier. He co-authored a review on the subject published in the Annual Review of Ecology, Evolution, and Systematics.

Invasions of Freshwater Fish: A Comprehensive Review
In the second part of the program, we head to the Gaillarde campus where we visit the sensory analysis platform of the Sciences for Oenology laboratory with Eric Picou. Here, a panel of experts is trained to measure and control the organoleptic characteristics of wines. These include floral, fruity, woody, toasty, and empyreumatic notes, which serve the objectives of numerous research programs in oenology.
Finally, Sylvie Rapior, a researcher at the Center for Functional and Evolutionary Ecology, will be our last-minute guest. She will talk to us about the Mushroom and Autumn Plants Fair, which will be held on Saturday and Sunday at the Faculty of Pharmacy.
