- Description: An environment-only classification missed latitudinal benthic patterns that appeared when biological occurrence records were added—but spatial-block performance remained weak.

Geography

Northwest Pacific seamount region

System

Deep-sea seamount benthic habitats

## WHAT THE EVIDENCE SAYS

Researchers compared abiotic habitat classification with a framework that incorporated limited benthic occurrence data in a poorly sampled Northwest Pacific seamount region. Biological information revealed model-derived latitudinal occurrence differences not identified from environmental variables alone. Twelve candidate areas together covered 27.12% of the study area and represented all classes produced by both approaches.

## WHY IT MATTERS / OUR READ

Environmental surrogates are useful where sampling is sparse, but even limited biology can change the spatial story. For deep-sea planning, the value of a habitat map depends partly on knowing which ecological patterns were never available to the environmental-only model.

## CAVEATS / UNCERTAINTY

Biological data were limited and spatial-block model performance was low, indicating substantial uncertainty beyond sampled locations. The 12 candidate areas are a representativeness exercise, not a validated protected-area prescription, and the authors call for further spatial validation.
