Unsolicited listicle: My list of the most criminally underused/underappreciated phylogenetic comparative methods. Note, I am not involved in ANY of these methods; but I see them as things people are often asking of comparative data but have been surprised at how infrequently they have been cited.

With the « Life of Retaria » we do podcasts! Listen to the first one during which we interviewed @fabnot.bsky.social #protistsonsky

My friends in the Life of Retaria group decided to make a podcast! In the first episode, they interview @fabnot.bsky.social about his journey as a scientist. I loved the first episode, hope you do too! @juliemeilland.bsky.social @sandinmm.bsky.social et al.

A lovely collaboration with @plannapus.bsky.social, Noritoshi & @fabnot.bsky.social, where we merged the extensive groundwork on the Polycystine fossil record with extant molecular diversity to trace the evolutionary history of Radiolaria from their appearance ~760 million years ago
sandinmm.bsky.social
Despite 150+ years of Radiolaria diversity research, we have just scratched the surface. Nearly half of Radiolaria diversity might be naked hiding in plain sight! We unveiled the diversity and evolution of Radiolaria beyond "the stars of the ocean"

Ah! And if you arrived until here and were wondering about the little golden dots, yes, they are photosynthetic symbionts identified as Scrippsiella. A common dinoflagellate found in symbioses with other planktonic groups like Acantharia (also Radiolaria) or the jellyfish Vellela
sandinmm.bsky.social
We hypothesize that such a trait could increase the effective volume to weight ratio favoring prey contact and capture, and provide an advantageous microenvironment for symbionts, enhancing ecological success in nutrient-depleted waters.

Despite Phlebarachnium was rarely observed, metabarcoding analyses revealed a strong biogeographic affinity to oligotrophic water masses and co-occurrence with other gelatinous-bearing Radiolaria, reaching relative abundances of more than 13% to the total eukaryotic reads in specific samples
sandinmm.bsky.social
We introduce the first molecular characterization of Phlebarachnium, one of the few Radiolaria known to live within a gelatinous matrix besides Collodaria. Yet these lineages of Nassellaria developed independently the ability to produce the gelatinous matrix ∼150 million years ago
sandinmm.bsky.social
Why do some planktonic protists develop a gelatinous matrix? We suggest that this original adaptation is a strategy to cope with ocean oligotrophy: doi.org/10.1111/1462...
Led by @n-llopis-m.bsky.social, and thanks to all co-authors, I'm very happy to finally see it out!

Adding planktonic algae to anoxic marine sediments promotes the anaerobic growth of phagotrophic #eukaryotes. The #Neoproterozoic Rise of Algae may have similarly promoted benthic phagotrophs, directing carbon, energy, and nutrients to early animals. #ProtistsOnSky

The Rise of Algae promoted eukaryote predation in the Neoproterozoic benthos
The rise of marine algae stimulated microbial predation at the seafloor, rerouting carbon and energy to the earliest animals.

New preprint led by Ruben Gonzalez-Miguens for a new coi database that should be useful to annotate metabarcoding datasets with protists.

I am looking for an ERC-funded postdoc to work on spatial proteomics of microalgae (red algae and glaucophytes). The ideal candidate will have experience with mass spec and data analysis (R), but above all a keen interest in broad eukaryote evolution and protists #protistsonsky (1/2)

JOB ALERT!
A fully funded PhD opportunity awaits at Uppsala University, Sweden, focusing on the evolution and biology of lichen photobionts.

The position will involved field work, molecular lab work and data analyses (from meta-omics to pop genetics).
