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 …

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

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

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 …

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 …

Postmortem body curvature introduces error in fish morphometric data. Compared to living
fish, the causes of such body curvature in fossils may be due to additive taphonomic …

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

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 …

Brown trout is a salmonid fish with a natural range extending throughout western Eurasia
and North Africa. Due to its commercial value, it has also been introduced worldwide. In …
