Building and Visualising Ordinations of Shape Data in R With Morphospace

open access: yesEcology and Evolution
Ordination is a critical step of geometric morphometrics that allows simplification of high‐dimensional shape spaces into low‐dimensional representations summarising shape variation.

The variability of giraffe skull morphology

open access: yesJournal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Are integrative systematic tools efficient toward unraveling species diversity with the genus Jania (Corallinaceae, Rhodophyta)?

open access: yesJournal of Phycology, EarlyView.
Abstract The articulated genus Jania currently comprises 54 accepted species, making it the fourth most speciose genus among corallines, following Lithophyllum, Amphiroa, and Lithothamnion. Unlike these other genera, Jania is relatively easy to identify at a generic rank. However, morpho‐anatomical characters are insufficiently discriminant for species

Lucid Dreaming Frequency Associated With Grey–White Matter Networks: An Exploratory Multimodal MRI Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Lucid dreaming, defined as the experience of becoming aware of dreaming while dreaming, offers a unique window into a state of consciousness characterised by a blending of the sensory vividness of REM sleep with the self‐awareness of wakefulness. While past functional imaging has shed light on the neural activity supporting lucid dreaming, the

Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Hemp seed counting and morphometric analysis method comparison

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract The USDA ARS Hemp Germplasm Laboratory recently acquired over 800 hemp accessions (Cannabis sativa L.). Variation in hemp seed size characteristics is needed to develop quantitative standards to support the transition of hemp grain into a commodity.

Integrating mandibular evidence to assess morphological variation of the Australopithecus afarensis maxilla

open access: yesThe Anatomical Record, Volume 309, Issue 6, Page 1483-1505, June 2026.
Abstract Geometric morphometric analyses are used to explore variation of maxillary dental arcades of Australopithecus afarensis, expanding on the work of Hanegraef and Spoor, 2025 (Morphological variation of the Australopithecus afarensis maxilla.

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 452-462, June 2026.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Multivariate trait profiling and genetic diversity in a global foxtail millet germplasm panel

open access: yesPlant Biology, Volume 28, Issue 4, Page 1077-1088, June 2026.
Four elite foxtail millet groups discovered from 260 accessions: perfect for breeding climate‐resilient, high‐yielding dual‐purpose crops. Abstract Foxtail millet (Setaria italica L.), known for its climate resilience and dual‐purpose utility, is underutilized in breeding programs despite its agricultural potential.
