Congratulations Dr. Hendrikje Jorissen!

Hendrikje successfully defended her PhD thesis on June 26th after 3.5 years of hard work and dedication. Due to the spread of COVID-19, the defence had to be done using videoconference. It comprised a slide presentation lasting 45 minutes, followed by 2 hours of questions from six jury members. Colleagues, friends and family were able to watch the defence remotely. It’s been great working with you. We are so proud of you!

Wet again after 2-month pause due to COVID-19

While Chloe’s PhD fieldwork was in full progress in Moorea, everything got shutdown with the arrival of COVID-19 on the French Polynesian territory in March 2020. Chloé & Hugo Bischoff, a Master student from the University of the French West Indies, had to stay dry at the CRIOBE lab facilities for two long months. However, fieldwork could start again this month. The team cleaned off experimental bommies from macroalgae which had barely grown back. Transplantation of Pocillopora damicornis colonies on the bommies and methodological testing of chemical sampling and flume chambers are now underway. It feels great to be wet again!

ICRS 2020 postponed to 2021 due to COVID-19 | Bremen, Germany

Due to the spread of COVID-19, the 14th ICRS has been postponed to the week of 18 - 23 July 2021. The session "Coralline algae: what are their global contributions to coral reefs now and in future oceans?” co-chaired by Maggy with Christopher Cornwall, Steve Comeau and Guillermo Diaz-Pulido remains in the 2021 ICRS program. We hope to see you at the conference in Bremen, Germany, in July 2021. In the meantime, stay safe and healthy!

TURBOCORAIL field experiment launched

In November 2019, Fabio manipulated sea urchin and Turbinaria densities on coral bommies in the lagoon of Moorea. The experiment will be maintained by Chloé and other students for the next few months. With this experiment, we hope to know whether different levels of urchin grazing pressure can regulate the spread and persistence of stands of Turbinaria and associated algae. Fabio also experimented with algal spores and chemicals to determine how the benthos affects settlement success of the alga. These experiments will enhance our understanding of the mechanisms underpinning the expansion of Turbinaria and, hopefully, strategies for its control.
