Birds have an excellent ability to learn to discriminate harmless insects from those that they mimic on the basis of subtle differences in appearance, according to a study in Nature.

Glad to share our paper revealing that inland and coastal waters, while covering <10% of Earth’s surface, contribute ~20% of global nitrogen fixation!

Global importance of nitrogen fixation across inland and coastal waters
Biological nitrogen fixation is a key driver of global primary production and climate. Decades of effort have repeatedly updated nitrogen fixation estimates for terrestrial and open ocean systems, yet...

Particle-associated N2 fixation by heterotrophic bacteria in the global ocean
Heterotrophic bacteria fix N2 in more diverse environments than previously thought, critical for the oceanic nitrogen cycle.

Antarctic krill vertical migrations modulate seasonal carbon export
Vertical migrations by marine organisms contribute to carbon export by consumption of surface phytoplankton followed by defecation in the deep ocean. However, biogeochemical models lack observational ...

Ces algues des neiges qui deviennent rouge sang au soleil
La neige se pare parfois de couleurs originales… et le plus intrigant, c’est que la neige rouge sang accueille des algues qui favorisent la biodiversité dans ce milieu que l’on croit si « vierge ».
