A 4D geometric morphometrics workflow to quantify complex biological motion

Methods in Ecology and Evolution, EarlyView.
Abstract Quantifying biological motion is fundamentally tied to quantifying the biological structures that produce that motion. Yet, this dependence makes it essential to decouple motion from static morphology to enable general, comparable analyses across individuals and conditions. In this work, we present a methodological pipeline to study biological

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

Methods in Ecology and Evolution, EarlyView.
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 covariation ...

Análise descritiva por ordenação: aplicação na caracterização sensorial de biscoitos laminados salgados Ranking descriptive analysis: application in the sensory characterization of cracker biscuits

Brazilian Journal of Food Technology, 2012
A Análise Descritiva por Ordenação (ADO) foi aplicada na caracterização de biscoitos cream cracker e água e sal comerciais, empregando julgadores pré-selecionados, mas sem experiência prévia em análise sensorial.

The application of geometric morphometric analysis in the study of bovine ovarian morphology

Theoretical and Applied Veterinary Medicine
Geometric morphometrics offers superior analytical capabilities compared to traditional linear morphometry for studying biological shape variation. The bovine ovary serves as an excellent model due to its distinct features and morphological plasticity ...

Flash profile as a rapid descriptive analysis in sensory characterization of traditional dry fermented sausages [PDF]

Food and Feed Research, 2020
Traditionally, sensory analysis techniques are separated on those performed with trained sensory panellists (analytical procedures) and those with consumers (hedonic tests). Nowadays, dividing line between these two approaches tends to blur.

Wari Lithic Technology on the Northern Coast of the Andes: Geochemical, 2D Geometric Morphometric, and Technological Analyses of Obsidian Bifaces From San José de Moro

Archaeometry, EarlyView.
ABSTRACT This study examines Wari obsidian production in a cache of 39 bifaces found at the Late Moche site of San José de Moro (Jequetepeque Valley, North Coast of Peru, 700–850 ad). Portable X‐ray fluorescence, geometric morphometric, and technological analyses were used to investigate raw material provenance and bifacial production.

Protocol to quantify bird nest morphology via image analyses using linear measurements and geometric landmarks

STAR Protocols
Summary: Here, we present a protocol to quantify bird nest morphology via image analyses. We describe steps for collecting linear size measurements, placing geometric landmarks, and undertaking generalized Procrustes analysis to extract coordinate data ...

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Allometry and Geographic Variation in Forewing Shape and Size Among Honey Bee (Apis mellifera L.) Populations from Türkiye

ISPEC Journal of Agricultural Sciences
Wing shape provides an important source of morphological information for evaluating population differentiation in honey bees, but the extent of geographic variation relative to allometry and within-population variation remains unclear.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
