6 MONTHS OF IDENTIFICATIONS

6 MONTHS OF IDENTIFICATIONS

October 7th, 2022 – After 6 months, the hyperdiverse platform is quite a success! 20 taxonomists are actively identifying our neogastropod vouchers, and so far, they have identified 4,000+ specimens, for a total of 7,000+ proposed identifications. It’s a long road toward the almost 40,000 specimens of neogastropod in the MNHN database, but we are on our way!

ALLAN IS STARTING A PhD

ALLAN IS STARTING A PhD

October 3rd, 2022 – After a (very) successful Master 2 training program, Allan is now starting his PhD with the ERC team. He will be analysing the many transcriptomes that are already available and those that will be produced over the next year. It’s a great way to test the bioinformatic pipeline he designed during his Master 2 program. Welcome back!

THANKS TO CLAUDIA

THANKS TO CLAUDIA

September 30th, 2022 – After two years of hard work sorting, inventorying, verifying labels, imaging, tissue-clipping, etc… several thousands (tens of thousands!) of neogastropod vouchers for the ERC project, Claudia is now leaving the ERC team. Well, she is not going very far: she found a new position in the 3E team (who hosts the ERC team)! Congratulations, Claudia, and thanks for all your work!

A SUCCESSFUL SAMPLING

A SUCCESSFUL SAMPLING

September 27th, 2022 – The fieldtrip in Noumea was a success! Five species have been sampled for both genomic and proteomic studies, with a total of c.a. 500 tissue-samples. Our deepest thanks to the divers (Valentin Dutertre, Nicolas Charpin et Serge Rolland), the Lagons Aquarium in Noumea (who hosted our mini-workshop), Maria Vittoria Modica, who dissected all the samples, and for help with logistics (Sébastien Faninoz and Claire Bonneville) Ready for sequencing!

SAMPLING IN NOUMEA

SAMPLING IN NOUMEA

September 5th, 2022 – Valentin Dutertre, Nicolas Charpin and Serge Rolland (from left to right) are currently diving in New Caledonia, around Noumea, to collect samples for the ERC project. On the menu: Conus striatus, Conus magus, Oliva amethystina and one species of Cancellariidae (to be identified). Over the next few days, they will also be night diving to collect marginellids, which suck the blood of parrot fish at night. Good luck!

ALMOST 2 YEARS OF CURATING THE NEOGASTROPOD COLLECTION

Almost 2 years of curating the neogastropod collection

August 29th, 2022 – Claudia and Melanie have made great progress in curating the neogastropod collection. In just under two years they have processed over 32500 specimens and posted 9150 new images to the database. Most of the existing collection will likely be inventoried by the end of the year. We look forward to processing all new arrivals!

WCM 2022: SARAH'S TALK

WCM 2022: Sarah’s talk

August 1st – 5th, 2022 – The WCM 2022 was also the opportunity for Sarah to present her results. Using the two genomes obtained during the ERC project, she demonstrated that these genomes experienced a whole genome duplication, and proposed the hypothesis that this event may have triggered the apparition of toxin-coding genes and favored the diversification of the neogastropods.

WCM 2022: THOMAS’ POSTER

WCM 2022: Thomas’ poster

August 1st – 5th, 2022 – During the WCM 2022, Thomas presented the pipeline he developed to identify conserved exons to reconstruct the neogastropod phylogeny. His poster also included preliminary results, with a phylogeny of Conoidea, Mitroidea and Buccinoidea including c.a. 380 taxa. In the picture, he is detailing his results to Maria Vittoria Modica.

THE HYPERDIVERSE PLATEFORM

THE HYPERDIVERSE PLATEFORM

April 25th 2022 – We are proud to announce the official launch of the Hyperdiverse Platform!
Accessible through the project website (www.hyperdiverseproject.com/specimens-single-page), this platform allows taxonomists, whether amateur or professional, to propose identifications for all the specimens that will be studied during the project. These identifications will be uploaded to the MNHN collection database and will serve as a basis for the integrative taxonomy and phylogeny studied performed during the ERC project.

WELCOME ALLAN

WELCOME ALLAN

March 1st 2022 - We now welcome Allan Ringeval, a 2nd year Master’s student from the Université de Lille. He will join our team for a 6-month training session.

BACK IN THE FIELD

BACK IN THE FIELD

May 25th 2021 - Nico and Maria-Vittoria are currently in the field collecting samples for the genomic, transcriptomic and proteomic analyses. So far, we found Monoplex corrugatus and Stramonita haemastoma; their genomes were recently sequenced but replicates were needed for the transcriptomic and proteomic analyses. We are also targeting other species, such as Columbella rustica (very common) and Pusia ebenus, and hope to have luck again in the next few days!
