Objectifying processes: The use of geometric morphometrics and multivariate analyses on Acheulean tools

Journal of Lithic Studies, 2020
Nowadays, the fruitful discussion regarding the morphological variability of handaxes during the Middle Pleistocene has reached a decisive moment with the use of more accurate statistical methods, such as geometric morphometrics (GM) and multivariate ...

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.

Leaf shape and size variability of Dryas octopetala in the Central Great Caucasus (the Kazbegi region, Georgia) based on traditional and geometric morphometrics [PDF]

Botanica Serbica
While soil pH is known to be a key driver of plant species composition, we still have a poor understanding of the quantification of the responses of leaf traits to different soil types, especially in highly sensitive alpine environments susceptible to

Morphometric Identification of Queens, Workers and Intermediates in In Vitro Reared Honey Bees (Apis mellifera).

PLoS ONE, 2015
In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens and workers, which are normally are not seen in hive-reared bees, except when larvae older than three days

Head morphology in three species of tiger beetles (Coleoptera: cicindelidae): a geometric morphometric study

The European Zoological Journal
Tiger beetles are one of the world’s most studied groups of insects. They are similar in body shape and proportions and have a well-sclerotized head with large protruding eyes that make it wider than the pronotum.

3D Bioprinted Breast Cancer‐Stroma Model with Tailored Migration‐Permissive Bioink Reveals Impact of Adipose‐Derived Stromal Cells on Cancer Cell Migration and Invasion Dynamics

Advanced Healthcare Materials, EarlyView.
A migration‐permissive bioink composed of methacrylated collagen type I and thiolated hyaluronic acid enables 3D bioprinting of breast cancer‐stroma models. Single‐cell tracking reveals that adipose stromal cells enhance tumor cell motility and stromal invasion, accompanied by collagen remodeling, and a shift in tumor cell morphology.
