Within a pitcher plant, bacteria break down prey to feed the plant. As the leaf ages, bacteria become less diverse, but more efficient at degrading insects. It appears that species that are strong degraders are weak competitors. Read now ahead of print!

Biologists who teach: in what order do you teach the four forces of evolution? Genetic drift first or selection first? And I'm still struggling to smoothly fit in HWE so that its utility is emphasized (students focus so much on how likely it is that assumptions are violated).
