Virtual EchinoClub

The 2024 EchinoClub organizers are planning a series of seminars and discussions.

Margherita Perillo
Catherine Schrankel
Rossella Annunziata
Nat Clarke

Sessions will be at 10am Eastern time for 90 minutes and feature one or two lab groups presenting their work leaving time for discussion and community building.
A link will be sent the day before the meeting, if you have registered for a previous meeting then you do not need to register again.
For new registrations please send an email request to Echinobase@andrew.cmu.edu and you will be added to the list. 

Schedule 

The Lab of Andreas Heyland, University of Guelph, Canada will present Friday September 13, 2024 
Title: Genomic and non-genomic signaling in the development and evolution of echinoderms
Speakers: Andreas Heyland, Elias Taylor and Katherine Tieman

Past presentations

Tyler Carrier from the GEOMAR Helmholtz Centre for Ocean Research presented on Thursday May 23, 2024.
Title: Sea urchins and their developmental symbioses
Synopsis: Development is a balance between the highly conserved genomic network and environmental signals. This talk concerns a third factor: microbial symbioses. Specifically, this talk will focus on how an intra-kingdom heist enhances the fitness of sea urchins and their offspring.

The recording can be accessed HERE.

The Lab of Sam Dupont presented on Thursday April 25, 2024, 14:00 UTC and the recording is available HERE.

Title: Ecophysiology of global changes
Speakers: Sam Dupont,  Jossias Duvane and Damboia Cossa

Echinobase presented on Thursday February 22, 2024 at 15:00 UTC.
The presentation provided updates to the site since our last EchinoClub in September 2021.
Then some tips on data access and usability with time for questions and discussion.
