Nakagawa and Parker 2015
Why do we replicate?
- Assess the validity of prior findings
- probe the generality of those findings
Levels of replication
- Exact (also known as “direct”): highest fidelity to the original work. But in ecology, usually can only be ‘close’ replications.
- Partial: there is a spectrum of partial replications, from close to limited. These have slight procedural differences.
- Conceptual: uses distinctly different study designs to test the same hypotheses.
- Quasi-replication (cross-species or system)
Conceptual replications: when results concur, we can define generality. If they conflict, we cannot draw robust inferences about why this occurs.
