Merry Christmas & Happy New Year

The LEMAR lab wishes you happy Holidays and a 2021 year better than 2020 (it shouldn’t be too hard, though…)   Thanks to Valentin Foulon, Natalia Llopis & to the radiolarians for this graphic creation.   Download the high resolution file here

Relationship between membrane n-3 HUFA content and mitochondrial efficiency

The relationship between membrane fatty acid content and mitochondrial efficiency differs within- and between- omega-3 dietary treatments   Abstract An important, but underappreciated, consequence of climate change is the reduction in crucial nutrient production at the base of the marine food chain: the long-chain omega-3 highly unsaturated fatty acids (n-3 HUFA). This can have dramatic […]

A current synthesis on the effects of electric and magnetic fields emitted by submarine power cables on invertebrates

Abstract The goal of clean renewable energy production has promoted the large-scale deployment of marine renewable energy devices, and their associated submarine cable network. Power cables produce both electric and magnetic fields that raise environmental concerns as many marine organisms have magneto and electroreception abilities used for vital purposes. Magnetic and electric fields’ intensities decrease […]

Radiolarians and the silicon cycle: Natalia Llopis-Monferrer’s work in the spotlight!

The American Geophysical Union (AGU) has declared “Research Spotlight” the recent article by Natalia Llopis-Monferrer in “Global Biogeochemical Cycles” on the importance of radiolarians (marine planktonic organisms) in the silicon cycle of the world ocean. This recent work re-evaluates the role of these tiny protists, which could contribute up to one-fifth of the world’s silica […]
