Data for: Phylogenetic structure of body shape in a diverse inland ichthyofauna

Body shape is a fundamental metric of animal diversity affecting critical behavioral and ecological dynamics and conservation status, yet previously available methods capture only a fraction of total body-shape variance. Here we use structure-from-motion (SFM) 3D photogrammetry to generate digital 3D models of adult fishes from the Lower Mississippi Basin, one of the most diverse temperate-zone freshwater faunas on Earth, and 3D geometric morphometrics to capture morphologically distinct shape variables, interpreting principal components as growth fields. The mean body shape in this fauna resembles plesiomorphic teleost fishes, and the major dimensions of body-shape disparity are similar to those of other fish faunas worldwide. Major patterns of body-shape disparity are structured by phylogeny, with nested clades occupying distinct portions of the morphospace, most of the morphospace occupied by multiple distinct clades, and one clade (Acanthomorpha) accounting for over half of the tota..., 3D models of fish specimens from the Lower Mississippi Basin were created using SFM 3D photogrammetry. The models were then landmarked in three dimensions using the free program Slicer. Landmark files for each model were exported from Slicer and are found in the \"3D_landmarks\" folder. The landmarks files were loaded back into Slicer and processed using the GPA module. The GPA module outputs were exported as the folder \"Slicer_Output\".

We placed 11 homologous landmarks on 3D models representing the fish fauna of the Lower Mississippi River Basin to explore phylogenetic structure of body shape across an entire fauna.

This dataset contains raw 3D landmark data of 232 3D models of fishes, supplementary tables, Slicer GPA outputs, and R scripts to reproduce the analyses and figures of the morphospaces.

## Description of the data and file structure

Landmark Data:
\"3D_landmarks\" - Folder containing raw (before Procrustes superimposition) landmark data exported from Slicer in .fcsv format. These files can be viewed using Microsoft Excel or your choice of text editor.

\"Slicer_GPD_output\" - Folder containing output files after processing the raw 3D landmark files in the SlicerMorph GPA module. The \"analysis.log\" file lists all specimens used and what files for R to reference when running the analysis to extract...
