Arching effect on fish body shape in geometric morphometric studies
Upward and downward arching of the body was observed during a study on redfishes Sebastes sp. population structure in the north‐west Atlantic Ocean. The present study investigated the potential causes of this arching artefact. The results suggested that it is not related to biological factors (size...

Upward and downward arching of the body was observed during a study on redfishes Sebastes sp. population structure in the north‐west Atlantic Ocean. The present study investigated the potential causes of this arching artefact.

The consequences of the arching artefact on data analysis are discussed. An approach coupling a PCA‐based model of the arching with Burnaby’s orthogonal projection is proposed for removing the artefact from the data. |
