Query: Navigation between states in ecological communities by taking shortcuts,
  with application to control   Many community ecology problems can be framed in terms of controlling the
transition from an initial state to a desired state. However, it is often
unclear what action sequence (if any) would yield the desired state. Here we
develop a simple approach for navigating to desired states, applicable when the
costs and outcomes of actions are known. We find lowest-cost action sequences
(adding a species, removing a species, changing the environment, waiting) via
A* search on a state diagram. Lowest-cost sequences usually are indirect and
leverage waiting for natural transitions caused by competitive exclusion. In
tests on simulated and empirical data across taxa, our approach provides ~50%
probability of substantial cost improvement relative to nominal approaches. As
an example, numerous successes are predicted in gut microbial communities for
removing the pathogen Clostridium difficile. This work thus provides a
conceptual foundation for efficient state transitions in species-rich
communities.
