Want to learn about viruses before the live session next week? The talks are pre-recorded & available now, so what are you waiting for? Let's highlight the invited talk by @virome_girl entitled "Deciphering the “Dissolved”: Ecological Roles of Aquatic Viruses" without spoilers! https://twitter.com/jgi/status/1337464923740393475
It starts off with amazing graphics (from https://www.annualreviews.org/doi/abs/10.1146/annurev-marine-120709-142805?journalCode=marine) to give background on how viruses are important. Then Mya explains how the Lab is interested in if viruses affect an ecosystem when they are not infecting a host?

She explains how viruses can disproportionately tie up phosphorus, nitrogen, & iron - Iron phage makes a debut! Then we go into an ISOTOPE EXPERIMENT
!!! where (57)Fe is used to track what amount of Fe ends up in the dissolved fraction and in which category.

The hypothesis: "A significant amount of dissolved Fe could be complexed within phage"
No spoilers but we think viruses are critical for availability of iron in the oceans & Mya gives an example of how this work is applicable to other environments. Personally, I am interested in how viruses affect Fe and P availability in tropical soils.
Anoxic events can enhance plant & microbial P utilization as it lowers Fe-P sorption strength described in https://esajournals.onlinelibrary.wiley.com/doi/full/10.1002/ecy.2928. Oxic/anoxic events are frequent in these soils & in my previous talk () I explained that we see different viruses in each.
I am still figuring out what it all means, but as Mya said there is much more to this Ferrojan Horse Hypothesis. I highly recommend watching Mya's @theAGU talk ASAP & join the live session on Wednesday with your Qs ready.
