Aim: To analyse the diversity and distribution of oceanic pelagic cephalopods along the Eastern Pacific Ocean, assessing the existence of biogeographic structuring, and the role of physical variables in generating geographical patterns. We hypothesized that the control by environmental factors, and the effect of geometric constraints, determine the range size and limits of distribution of oceanic cephalopods along the eastern Pacific Ocean, generating a latitudinal gradient in species richness. Location: Eastern Pacific Ocean (60°N – 60°S), from the Gulf of Alaska to the Southern Ocean. Methods: Based on a literature review and >5,000 records obtained from collections, we constructed a presence-absence matrix including 61 latitudinal bands (2° each) along the Eastern Pacific, and estimated species richness and range endpoints at each band. Biogeographic units were determined by means of multivariate analyses. Species richness was compared with null model predictions in order to test for the existence of ... : Distribution data matrixData base based on a comprehensive literature review and >5,000 records obtained from biological collections (first sheet).
