## WHAT THE EVIDENCE SAYS

Editorial interpretation of evidence discussed in this edition.

## WHY IT MATTERS / OUR READ

Ecological sampling has a vertical dimension. The Congo camera work is methodological as much as zoological. If sampling only one stratum changes what we think we know about community composition and habitat relationships in forests, the analogous question applies elsewhere: what dimensions of a system are systematically invisible because our standard sampling design was built around convenience?

## CAVEATS / UNCERTAINTY

The two studies examine particular forest settings and sampling designs. More vertical coverage can improve detection, but does not eliminate all survey bias.

Ecological outcomes depend on context: the intervention, the place, the system and the timescale.
