Do cladistic and morphometric data capture common patterns of morphological disparity? [PDF]

, 2015
The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework.

Studying avian encephalization with geometric morphometrics [PDF]

Journal of Anatomy, 2016
AbstractEncephalization is a core concept in comparative neurobiology, aiming to quantify the neurological capacity of organisms. For measuring encephalization, many studies have employed relative brain sizes corrected for expected allometric scaling to body size.

Arabidopsis phenotyping through Geometric Morphometrics

GigaScience, 2017
AbstractIn recent years, much technical progress has been done regarding plant phenotyping including the model speciesArabidopsis thaliana. With automated, high-throughput platforms and the development of improved algorithms for the rosette segmentation task, it is now possible to massively extract reliable shape and size parameters for genetic ...

Measuring the shape. Performance evaluation of a photogrammetry improvement applied to the Neanderthal skull Saccopastore 1 [PDF]

, 2018
Several digital technologies are nowadays developed and applied to the study of the human fossil record. Here, we present a low-cost hardware implementation of the digital acquisition via photogrammetry, applied to a specimen of paleoanthropological ...

Geometric Morphometrics of Hominoid Infraspinous Fossa Shape [PDF]

The Anatomical Record, 2014
ABSTRACTRecent discoveries of early hominin scapulae from Ethiopia (Dikika, Woranso‐Mille) and South Africa (Malapa) have motivated new examinations of the relationship between scapular morphology and locomotor function. In particular, infraspinous fossa shape has been shown to significantly differ among hominoids.

Geometric morphometrics of endophytic oviposition traces of Odonata (Eocene, Argentina) [PDF]

Royal Society Open Science, 2020
The insertion of the Odonata ovipositor in the plant tissue generates a scar that surrounds the eggs (trace). In insects, individual egg traces are known to vary in size, but their variation in individual shape is mostly unknown.

Geometric morphometrics in the cloud

Infection, Genetics and Evolution, 2019
XYOM, for XY Online Morphometrics, is an online implementation of the geometric morphometric (GM) approach. It is a platform-independent product, and is presented here as an optional alternative software to client side morphometrics software. From the point of view of the user, the interesting features of a web application are: no download, no ...

Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]

, 2014
The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...
