Gegenbaur's classical hypothesis of jaw-gill arch serial homology is widely cited, but remains unsupported by either palaeontological evidence (for example, a series of fossils reflecting the stepwise transformation of a gill arch into a jaw) or developmental genetic da...

Tara Oceans (which includes both the Tara Oceans and Tara Oceans Polar Circle expeditions) would not exist without the leadership of the Tara Ocean Foundation and the continuous support of 23 institutes (https://oceans.taraexpeditions.org/). We further thank the commitm...

International audience; Almost all cells require thiamin, vitamin B1 (B1), which is synthesized via the coupling of thiazole and pyrimidine precursors. Here we demonstrate that 5-(2-hydroxyethyl)-4-methyl-1,3-thiazole-2-carboxylic acid (cHET) is a useful in vivo B1 prec...

Accurate taxonomy, population demography, and habitat descriptors inform species threat assessments and the design of effective conservation measures. Here we combine published studies with new genetic, morphological and habitat data that were collected from seahorse po...

International audience; The brown algae (Phaeophyceae) are a group of multicellular heterokonts that are ubiquitous in today's oceans. Large brown algae from multiple orders are the foundation to temperate coastal ecosystems globally, a role that extends into arctic and...

International audience; Filamentous fungi asymptomatically colonize the inner tissues of macroalgae, yet their ecological roles remain largely underexplored. Here, we tested if metabolites produced by fungal endophytes might protect their host against a phylogenetically...

Glial cells play important roles in the development and homeostasis of metazoan nervous systems. However, while their involvement in the development and function in the central nervous system (CNS) of vertebrates is increasingly well understood, much less is known about...

This research was funded by the European Community's Seventh Framework program (FP7/2007–2013) under grant agreement No 222,719- LIFECYCLE and by an EU Research Infrastructure Action under the FP7 “Capacities” Programme, ASSEMBLE (no. 227,799, CCMAR Ref 00,215/2011) and...
