Landmark-Based Morphometric Study in the Fore and Hind Wings of an Iranian Race of European Honeybee (Apis mellifera meda)

Journal of Apicultural Science, 2013
Honeybee (Apis mellifera ) populations are usually distinguished using standard morphometric methods, mainly based on multivariate analysis of distances and angles.

Unification of frequentist inference and machine learning for pterygomaxillary morphometrics

Folia Morphologica, 2021
BACKGROUND: The base of the skull, particularly the pterygomaxillary region, has a sophisticated topography, the morphometry of which interests pathologists, maxillofacial and plastic surgeons.

Sexual Monomorphism and Size-Related Shape Change in the Beak of the Greater Flamingo (Phoenicopterus roseus). [PDF]

Vet Med Sci
Adult Greater Flamingos showed no significant sexual dimorphism in beak shape in either dorsal or lateral view. Geometric morphometric analyses revealed broad overlap between sexes, while dorsal beak shape displayed a significant size‐related allometric component.

Three-dimensional geometric morphometrics for studying floral shape variation [PDF]

, 2010
Variation in floral shape is of major interest to evolutionary and pollination biologists, plant systematists and developmental geneticists. Quantifying this variation has been difficult due to the three-dimensional (3D) complexity of angiosperm flowers.

Targeting Endogenous Lipophagy: A Novel Strategy to Enhance MSC Osteogenesis and Mineralization for Senile Osteoporosis Therapy

Advanced Science, EarlyView.
Schematic representation of the role of lipophagy in bone mesenchymal stem cells(MSCs). In healthy MSCs, functional lipophagy efficiently degrades lipid droplets to support oxidative phosphorylation and cellular energy production, thereby facilitating osteogenic differentiation and matrix mineralization.

Boosting Sensory Nerve‐to‐Bone Interactions Enhances Hedgehog Mediated Calvarial Bone Repair

Advanced Science, EarlyView.
Boosting sensory nerve activity via TrkA agonism strongly accelerates calvarial bone repair in adult mice. Furthermore, single‐cell RNA sequencing and neuron–bone interactome analyses identify these sensory neurons as a direct neural source of Hedgehog pathway ligands. Consequently, these ligands drive osteoblast differentiation of skeletal progenitors,

The Inheritance of Diagnostic Larval Traits for Interspecific Hybrids of \u3ci\u3ePapilio Canadensis\u3c/i\u3e and \u3ci\u3eP. Glaucus\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

, 2018
Traits distinguishing the closely related tiger swallowtail butterfly species, Papilio canadensis and P. glaucus, include fixed differences in diagnostic sex-linked and autosomal allozymes as well as sex-linked diapause regulation, and sex-linked ...
