Hello, my name is Agnès Boutet, I'm a researcher and lecturer at Sorbonne Université.
Hello my name is Yasmine Lund-Ricard and I'm a PhD student, and together with Agnès
we work at the Station Biologique de Roscoff.
In this course we would like to present chondrichthyans or cartilaginous fish
which include sharks, skates, and rays. Their common ancestor appeared more
than 450 million years ago. So together in this course we will see
why cartilaginous fish are very interesting models in evolutionary biology, and we'll
also see which kind of species have been used in biology so far. You will see also
why they are important in biological fields such as evo-devo, molecular phylogeny,
experimental biology, and also transdisciplinary fields.
In this course, different learning materials will be available to you
for you to familiarise yourself with the catshark model. These include a 2D
animation of the early steps of embryogenesis, as well as a
virtual lab which will teach you how to dissect out an embryo.
You will also have the opportunity to see different research topics where cartilaginous
fish are being used. We will also present functional approaches and descriptive
approaches that are possible with cartilagenous fish, and now
there are several genomes from sharks that are available and you will have the
reference papers of these genomes, and lastly you will also have the opportunity
to read an interview with Sylvie Mazan, a pioneering scientist for using the
catshark model in developmental biology.
And since reading is a big part of research a document will be present for you online
and this document will describe how a research article is organised and will
help you better prepare for the course to come.
We hope that you will enjoy this session with cartilagenous fish. Of course it will
be important to test your knowledge, so it is important to take the quiz
and we look forward to seeing you at the next Schmid Training Course. Bye!
