We usually think of photosynthetic bacteria as the main N2 fixers in the world's oceans . Using a mechanistic model we estimate that heterotrophic bacteria are responsible for 10% of the global N2 fixation. And it also occurs temperate waters. www.science.org/doi/10.1126/...
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.

Squid die when they reproduce. We estimate that sinking squid carcasses locks away 11-12 Mt carbon/year in the deep oceans. Increasing squid fisheries interrupts this sequestration and sends it to our dinner plates - where it is respired to the atmosphere. www.sciencedirect.com/science/arti...

Our online simulator of the FEISTY fish community model is now live. Simulate the food web structure fish communities based on bottom depth and zooplankton production:

The importance of teaching units ecological theory and modelling is under-appreciated. Great to hear that units are being taken seriously!

I have moved my online presence from twitter to Bluesky. Delighted to see so many from the old community are here already.
