Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

What Counts as Educational Innovation in Clinical Anatomy?

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Clinical anatomy has become a prominent setting for educational innovation because it links anatomical science with diagnostic imaging, procedural practice, surgery, simulation, and patient safety. However, the term innovation is used inconsistently.

Generative Artificial Intelligence Performance on University‐Level Human Anatomy Examinations: A Structured Narrative Review and Proposed MATRIX‐Anatomy Framework

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Generative artificial intelligence (GenAI) can perform strongly on written anatomy examinations, but whether such scores represent anatomical competence remains uncertain because results vary with the model, assessment, protocol, modality, scoring, and comparator.

Pollen landscape saturation on pollinator bodies reduces pollen deposition by subsequently visited bat‐pollinated flowers

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual selection in flowering plants often operates through male–male competition, yet the mechanisms underlying this phenomenon remain difficult to demonstrate. One potential arena for such competition is pollen placement on pollinators, where pollen grains from ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Immunostaining of βA-Activin and Follistatin Is Decreased in HPV(+) Cervical Pre-Neoplastic and Neoplastic Lesions

open access: yesViruses, 2023
The activin–follistatin system regulates several cellular processes, including differentiation and tumorigenesis. We hypothesized that the immunostaining of βA-activin and follistatin varies in neoplastic cervical lesions.
