Comparative Animal Anatomy Studies

Peripheral anatomy of the dolphin ear and associated nervous structures: insights from macroscopic dissection, DICE-{micro}CT, histology, and confocal microscopy

This study characterizes the neurovascular and sensory components of the dolphin peripheral auditory system using multiple anatomical techniques.

Trabecular structure correlates with leaping distance in tamarins

This study examines trabecular structure in tamarins to correlate it with leaping distance, finding higher node density in long leapers.

Differences between Scaly-sided Merganser (Mergus squamatus) and Common Merganser (M. merganser) feather microstructure

The paper compares feather microstructure between Scaly-sided Merganser and Common Merganser using SEM and statistical analysis, finding significant morphological differences that can aid in species identification.

Bone and cartilage staining protocol for large avian specimens: late-stage embryonic emu (Dromaius novaehollandiae) and adult chickens (Gallus gallus)

This paper presents a staining protocol for visualizing bone and cartilage in large avian specimens, optimized for adult chickens and late-stage embryonic emus.

Shouldering the challenge of deciphering avian palate evolution

The paper critiques a study on avian palate evolution, highlighting issues with taxon sampling and morphological interpretations.

A contribution to the anatomy of two rare cetacean species: the hourglass dolphin (Lagenorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

This study provides anatomical descriptions of the hourglass dolphin and spectacled porpoise using imaging and histology, revealing morphological features and supporting hypotheses about their diving behavior and thermoregulation.

Constrained variation in the internal architecture of avian wing bones

The paper examines internal wing bone structure in birds, finding that ecological factors have limited influence compared to body size, with implications for identifying flightless species in fossils.

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

This paper uses finite element analysis to investigate how maxillary fenestrations in lagomorphs affect cranial stress and strain, finding minimal impact on biting efficiency.

Avian telencephalon and cerebellum volumes can be accurately estimated from digital brain endocasts

The paper validates digital endocast surface area measurements as accurate proxies for telencephalon and cerebellum volumes in birds using histology and CT data.

Mammalian retinal specializations for high acuity vision evolve in response to both foraging strategies and morphological constraints

This study investigates how retinal specializations in mammals evolve in response to ecological factors and morphological constraints, finding support for associations between horizontal streaks and habitat type, and between orbit convergence and retinal acuity regions.

Haemolymphatic tissues of captive boa constrictor (Boa constrictor): morphological features in healthy individuals and with Boid Inclusion Body Disease

The paper examines the morphology of haemolymphatic tissues in healthy and Boid Inclusion Body Disease (BIBD)-affected boa constrictors, identifying structural features and disease-related changes.

The overlooked first intercostal ligament: Does it help to stabilize the Weberian apparatus?

This study investigates the first intercostal ligament (ICL1) in zebrafish, proposing its role in stabilizing the Weberian apparatus by minimizing non-optimal movement.

Development of the pulmonary vasculature in the gray short-tailed opossum (Monodelphis domestica) - 3D reconstruction by microcomputed tomography

This study uses microCT to reconstruct the pulmonary vasculature of gray short-tailed opossums from neonate to postnatal day 57, showing progressive vascular complexity and similarity to eutherian development.

Comparative neuroimaging of the carnivoran brain: Neocortical sulcal anatomy

This study examines neocortical sulcal anatomy across 26 carnivoran species using neuroimaging to identify patterns related to behavior and ecology.

Anuran Heart Metamorphosis: Anatomical Support for Pulmonary Blood Separation in the Early Aquatic Phase

The paper describes the anatomical development of the conus arteriosus in Bufo bufo tadpoles, showing early formation of structures supporting pulmonary blood separation before lung appearance.

The TMJ disc is a common ancestral feature in all mammals, as evidenced by the presence of a rudimentary disc during monotreme development.

The paper shows that monotremes develop a jaw joint disc primordium, suggesting the disc is an ancestral feature in mammals.

Comparison of the 3-D patterns of the parasympathetic nervous system in the lung at late developmental stages between mouse and chicken

This study compares the 3-D patterns of parasympathetic nerves in mouse and chicken lungs during late development, revealing three key similarities in nerve distribution and function.
