Here is a link to an NPR broadcast that I thought I would share… and I think I’m sharing it in the correct place. Its about the discovery/importance of Prochlorococcus.
Hi everyone!
OK so I got sucked in to the MLST diagrams. I started comparing the diagrams for Norway and the US (not the global diagrams, just the diagrams for each individual country). Not surprisingly, the founder STs in the US on average have MANY more SLVs than the Norway STs (there are more “spokes” on any given “wheel” in the US diagram). This makes sense to me, because (as of 1994) the US had a higher population density than Norway. When one person in a crowded US city is infected it is more likely that that strain will be passed to many new people and have the opportunity to give rise to new SLVs.
What I don’t understand is why more of the STs in Norway gave rise to SLVs (About 35 STs had at least 1 SLV in Norway, and about 13 had at least 1 SLV in the US.) I had a few inchoate ideas, but I would like to hear ideas from someone else. If I need to rephrase this question, just let me know.
