Temporal dynamics and biogeography of sympagic and planktonic photosynthetic microbial eukaryotes during the under-ice Arctic bloom

Clarence Wei Hung Sim, Catherine Gérikas Ribeiro, Florence Le Gall, Ian Probert, Priscilla Gourvil, Connie Lovejoy, Daniel Vaulot, Adriana Lopes dos Santos

Abstract Photosynthetic microbial eukaryotes play a pivotal role as primary producers in the Arctic Ocean, where seasonal blooms within and below the ice are crucial phenomena, contributing significantly to global primary production and biogeochemical cycling. In this study, we investigated the…

Is the Gelatinous Matrix of Nassellaria (Radiolaria) a Strategy for Coping With Oligotrophy?

Natalia Llopis Monferrer, Sarah Romac, Manon Laget, Yasuhide Nakamura, Tristan Biard, Miguel Sandin

Radiolaria are heterotrophic protists abundant in the world's oceans, playing important roles in biogeochemical cycles. Some host photosynthetic algae, contributing to primary production. Such mixotrophic behaviour is believed to explain their success in oligotrophic waters, notably Collodaria…

Meiofauna investigation and taxonomic identification through imaging—a game of compromise

Valentin Foulon, Abdesslam Benzinou, Kamal Nasreddine, Abdul Qayyum, Edwin Daché, Valentine Foulquier, Catherine Borremans, Marine Malloci, Colomban de Vargas, Daniela Zeppilli

Abstract Imaging methods have developed rapidly in recent decades, opening new opportunities for taxonomy and biodiversity studies of marine organisms. In particular, the microscopic size range, which used to be challenging to study due to time‐consuming preparation and observation steps, now…
