When more complex is simpler

A new modeling framework proposed by physicist Mikhail Tikhonov in Arts & Sciences demonstrates how a more complex microbial ecosystem can be more coarse-grainable, making it potentially easier for scientists to understand, than one with only a few microbes interacting.
Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects

Nonlethal parasites reduce how much their wild hosts eat, leading to ecosystem effects
