Multiple micro-predators controlling bacterial communities in the environment

- Relevance of existing ecological concepts on predation for the microscale unclear.
- Micro-predators of bacteria (protists, predatory bacteria, phages) differ in prey range.
- Interactions between micro-predators as well as combined impact on prey unclear.
- Need to combine ecological theory and understandings of predator traits.
- This could lead to a better exploitation of predatory interactions in, for example, wastewater treatment plants.
