Measurement error in geometric morphometrics

C Fruciano - Development genes and evolution, 2016 - Springer
Geometric morphometrics—a set of methods for the statistical analysis of shape once

Seeing distinct groups where there are none: spurious patterns from between-group PCA

A Cardini, P O'Higgins, FJ Rohlf - Evolutionary Biology, 2019 - Springer
Using sampling experiments, we found that, when there are fewer groups than variables,
between-groups PCA (bgPCA) may suggest surprisingly distinct differences among groups …

Genomic architecture of ecologically divergent body shape in a pair of sympatric crater lake cichlid fishes

Bat species comparisons based on external morphology: a test of traditional versus geometric morphometric approaches

DA Schmieder, HA Benítez, IM Borissov, C Fruciano - PloS one, 2015 - journals.plos.org
External morphology is commonly used to identify bats as well as to investigate flight and
foraging behavior, typically relying on simple length and area measures or ratios. However …

Genetic linkage of distinct adaptive traits in sympatrically speciating crater lake cichlid fish

C Fruciano, P Franchini, V Kovacova, KR Elmer… - Nature …, 2016 - nature.com
Our understanding of how biological diversity arises is limited, especially in the case of
speciation in the face of gene flow. Here we investigate the genomic basis of adaptive traits …

Towards understanding the genetic basis of mouth asymmetry in the scale‐eating cichlid Perissodus microlepis

F Raffini, C Fruciano, P Franchini, A Meyer - Molecular Ecology, 2017 - Wiley Online Library
