In reply to Jon Read:
"Is there good evidence this trade-off exists at all?"
I posted an article which finished with: "Overall, the results suggest that the current empirical evidence provides partial support for the trade‐off hypothesis, but more work remains to be done."
And without reading the paper you have decided that equates to no strong evidence.
I think it's exactly what I said in my OP which was "and a trade off between the two parameters is still not fully understood or fully supported." No where did I argue that this trade off definitely occurred, or was a strong relationship. I just asked was there any evidence of a change in its virulence, someone mentioned this yesterday on another thread.
In true UKC style you seem to be creating an argument because you are bored.
