The act of experimenting; practice by experiment.

A set of actions and observations, performed to verify or falsify a hypothesis or to research a causal relationship between phenomena.

As in much of biology, the most satisfying truths in ecology derive from manipulative experimentation. Tinker with nature and quantify how it responds.
