Geometric morphometrics is widely used to quantify morphological variation between
biological specimens, but the fundamental influence of operator bias on data reproducibility …

Geometric morphometric analyses are frequently employed to quantify biological shape and
shape variation. Despite the popularity of this technique, quantification of measurement error …

Quantifying phenotypes is a common practice for addressing questions regarding
morphological variation. The time dedicated to data acquisition can vary greatly depending …

Various ecomorphs of the shallow‐water Cisco Coregonus artedi were the dominant fish
planktivores in each of the Great Lakes until invasive species and overfishing resulted in …

In this study, we use a geometric morphometric and a character evolution approach to study
the evolutionary patterns of body-shape change and habitat transition in the Aulopiformes …

Species population structure and composition are components of essential biodiversity
variables (EBVs) to measure change in global freshwater diversity. Multiple stressors affect …

Objective Here we determine how traditional morphometrics (TM) compares with geometric
morphometrics (GM) in discriminating among morphologies of four forms of ciscoes of the …

Background Geometric morphometrics is a powerful approach to capture and quantify
morphological shape variation. Both 3D digitizer arms and structured light surface scanners …

Morphometric data from fish are typically generated using one of two methods: direct
measurements made on a specimen or extraction of distances from a digital picture. We …

The repeatability of findings is the key factor behind scientific reliability, and the failure to
reproduce scientific findings has been termed the 'replication crisis'. Geometric …
