Tissue Clearing for Lymph Nodes: 3D Mapping of Nerves and the Immune Microenvironment

iNew Medicine, EarlyView.
ABSTRACT Lymph nodes (LNs) are central hubs of adaptive immunity and key relay sites for metastatic tumour cells. However, conventional two‐dimensional histology samples only a small fraction of each node, potentially missing micrometastases and multifocal involvement while obscuring long‐range spatial relationships among tumour deposits, immune ...

Assessing the application of landmark-free morphometrics to macroevolutionary analyses

BMC Ecology and Evolution
The study of phenotypic evolution has been transformed in recent decades by methods allowing precise quantification of anatomical shape, in particular 3D geometric morphometrics.

Evaluating facial ontogeny of avian embryos using 3D geometric morphometrics

, 2014
Objectives: In order to study abnormal facial development, reference standards of normal development are required. It is challenging to obtain 3D data on early embryos, since they are comprised of non-differentiated tissue. We used optical projection tomography (OPT) (Bioptonics, UK), which images transparent specimens with UV light.

GEOMETRIC MORPHOMETRICS

, 2013
The aim of this article is to provide a simple introduction to Geometric MorphoMetrics (GMM). GMM is the numerical study of the interaction of size and shape with covarying factors in biology.

Dynamics of Size and Shape Variation During Embryonic Development in the Balkan Crested Newt

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Morphological variance in Triturus ivanbureschi embryos fluctuates during the tailbud phase, coinciding with developmental arrest caused by the balanced lethal system. Prehatching embryos show uniform variance. Our study reveals dynamics of morphological variability during early development and provides a baseline for further studies.

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

Boreas
The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is considered the common ancestor of all modern Ursini. U. minimus is thought to have been omnivorous, with a preference for invertebrates.

Application of Photogrammetry and Mesh Comparison in the Study of Human Cranial Morphology

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Photogrammetric methods for generating three‐dimensional (3D) models are becoming increasingly widespread in the fields of archaeology and biological anthropology. In particular, the study of the variability of skull morphology (generated by the ancestry of the individual or by the application of certain cultural practices) using 3D models is ...

Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

Oikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

Integrating vision, audition and olfaction traits: a roadmap for contrasting sensory ecologies of birds and rodents

Oikos, EarlyView.
Sensory ecology seeks to understand how organisms detect and use information from their environment, yet comparative analyses across multiple sensory modalities remain rare. Here, we present a roadmap for contrasting the sensory ecologies of birds and rodents using surrogate morphological and acoustic traits associated with vision, audition, and ...
