Comparing morphological integration patterns across groups using angular distances between PLS covariation axes

Mikel Arlegi

Abstract Morphological integration describes coordinated covariation among traits arising from shared developmental, functional, or genetic interactions and plays an important role in shaping evolutionary trajectories. In geometric morphometrics, two‐block partial least squares (PLS) analysis is widely used to identify dominant axes of …

Unclosed transverse foramen of the atlas: A systematic review and meta-analysis of prevalence and translational anatomical relevance

Juan Alberto Sanchis‐Gimeno, Mathias Orellana‐Donoso, Juan José Valenzuela‐Fuenzalida, Mikel Arlegi et autres

Background The atlas vertebra (C1) has a close anatomical relationship with the vertebral artery through the transverse foramen. Incomplete osseous closure of this canal, described as an unclosed transverse foramen (UTF), may modify the expected bony boundaries around the vertebral artery. Objective …

Craniofacial Fluctuating Asymmetry in Cross River Gorillas ( Gorilla gorilla diehli )

Amy J Spies, Kate McGrath, Amandine B. Eriksen, Jason S. Massey et autres

OBJECTIVES: Craniofacial fluctuating asymmetry (FA) in gorillas has been linked to environmental and/or genetic stress. Prolonged population declines increase levels of inbreeding, leading to developmental instability, which can manifest as FA. Among gorillas studied to date, craniofacial FA levels are highest in …

Hominoid cranial and C5 3D landmark dataset for integration analyses

Mikel Arlegi

This dataset contains 3D landmark coordinates of the cranium and fifth cervical vertebra (C5) for five hominoid species (Homo sapiens, Pan troglodytes, Gorilla gorilla, Pongo pygmaeus and Hylobates lar), with 20 adult individuals per species, stored as an R object (.rds). It …

The Trans-Evol project: Mapping Evolution in the South-West of the Turkana Basin (Kenya)

Aurélien Mounier, Sol Sánchez-Dehesa Galán, Marjolein D. Bosch, Fredrick Kyalo Manthi et autres

L’apparition d’Homo sapiens il y a plus de 233 ka en Afrique (Vidal et al., 2022), est le fruit d’un processus évolutif long et complexe qui a donné naissance à de nombreuses espèces d’hominines. Le bassin du Turkana, dans le rift Est-Africain, …

Quantifying between-species differences in morphological integration patterns using two-block PLS: an R implementation and sensitivity analysis

Mikel Arlegi

Abstract Morphological integration is commonly quantified within species using covariance or correlation structures, and two-block partial least squares (PLS) has become a standard tool for assessing covariation between anatomical modules. However, most applications focus on a global PLS axis for a pooled …
