Seagrass meadows are key blue carbon (C) ecosystems, storing large amounts of organic C over centuries. Their climate benefits may be reduced by methane (CH 4 ) emissions, whose microbial and environmental descriptors in Zostera noltii meadows, dominant seagrass in North‐Western Europe, remain poorly understood. We studied CH 4 fluxes, CH 4 ‐producing and consuming microbial communities and sediment physicochemical parameters...

Background and Objectives: Friedreich ataxia (FA) causes progressive impairment of communication due to gradual deterioration of speech, associated with impaired hearing, socio-cognitive and language skills. There is an urgent need to investigate the impact of this multiparametric alteration on patients’ lives. Therefore, the COMunication and ATAXia measure (COMATAX) was developed and validated in French and German. Methods: I...

Climate change threatens biodiversity when species cannot tolerate, adapt to, or track shifting environmental conditions to stay within their climatic niches. A major unresolved question is whether and how species' genetic diversity modulates these dynamics, buffering against range contractions or facilitating range expansions. To test this, we integrated the largest global databases of species range shifts and genetic diversi...

High‐latitude North Atlantic currents (60°–70°N) exhibit contrasting nutrient stoichiometries, but the spatial extent of post‐spring bloom iron (Fe) and nitrogen (N) stress on phytoplankton around Iceland remains poorly constrained. Here we pair in situ biogeochemical characteristics with 72 h Fe and N addition experiments in the East Greenland Current (EGC), Irminger Current (IC), Atlantic Current (AC), and East Icelandic Cur...

The ocean region off the Amazon shelf including the shelf break presents a hotspot for internal tide (IT) generation, yet its impact on phytoplankton distribution remains poorly understood. While previous studies have extensively examined the physical characteristics and dynamics of ITs, their biological implications – particularly in nutrient-limited environments – remain underexplored. To address this question, we analyzed a...

Habitat fragmentation and loss are key threats to biodiversity, yet their impacts on marine species remain poorly understood. Clownfishes, which rely on sea anemones for shelter and reproduction, provide an interesting model to explore how ecological specialisation mediates species responses to habitat perturbations. We used whole‐genome data from 382 individuals across 10 species with varying host specialisations to reconstru...

B‐vitamins are important co‐enzymes that have long been hypothesized to play key roles in marine ecosystems. However, environmental measurements remain scarce, which limits our understanding of their potential impact. Here, we present mass spectrometry‐based measurements of B‐vitamins (B 1 , B 2 , B 3 , B 5 , B 6 , B 12 ) and related vitamers along a transect in the Northwest Atlantic Ocean, in both particulate phase and disso...

Macroseismic surveys are of great interest to both the scientific community and the authorities.The aim of the MACROSISDATA project is to safeguard, disseminate, and promote through an online database the macroseismic survey documents collected by the French Central Seismological Bureau between 1921 and 1996. During this period, a total of 1428 earthquakes were surveyed to estimate macroseismic intensities (severity of ground...

Pollinators receive considerable interest due to their fundamental role in ecosystem functioning and human well‐being. Unlike farmlands, studies of urban pollinator‐promoting interventions are scarce and have not been synthesised, hampering policy implementation. To fill this gap, we compared pollinator‐promoting interventions (treatment) with conventionally managed (control) sites regarding vegetation, floral resources, and p...
