Q: what does this mean: "They specifically concentrated on bacterial
resource competition networks and studied pathogen invasion success in
simplified laboratory experiments and tomato plant roots."

A: Elaine Ingham:

It means they did not include the whole food web. So, they were trying to
demonstrate that resource competition is a significant way to suppress bad
guys, and it is great to be able to reference this paper when the
nay-sayers want to try to say that resource competition has not been proven
in the soil. As if resource competition among animals or people won't also
be a mechanism in soil. And as if Louis Pasteur and Robert Koch didn't
demonstrate that for human pathogens and beneficial organisms on people's
skin and in the digestive tract.

So, nice to have the reductionist science documenting that indeed, this
occurs around roots and benefits plants. But, they need now to repeat for
fungi. And protozoa, nematodes, microarthropods, worms, spiders,
............. Ah, reductionist science! Great way to have research to do
for the rest of your life.

But, you know how some people are, unless demonstrated and shown in
strictly controlled conditions, they won't bow to what your eyes tell you
every day.
