Canary Bornavirus (Orthobornavirus serini) Infections Are Associated with Clinical Symptoms in Common Canaries (Serinus canaria dom.)

open access: yesViruses, 2022
While parrot bornaviruses are accepted as the cause of proventricular dilatation disease (PDD) in psittacine birds, the pathogenic role of bornaviruses in common canaries is still unclear.

Differences between the Filling Velocities of the Left and Right Heart Ventricle in Racing Pigeons (Columba livia F. Domestica) and the Influence of Anesthesia with Isoflurane

open access: yesVeterinary Sciences, 2019
The ventricular filling velocities during diastole and the influence of isoflurane anesthesia on these blood flow velocities of the racing pigeon (n = 43) are evaluated by pulsed-wave (PW) Doppler sonography. Sonographic examination demonstrates an early

Therapsids as Mammals [PDF]

open access: yesEvolution, 1960
The therapsids are usually placed in the class Reptilia as its most mammal-like representatives. This is on the basis of the now commonly accepted criteria of jaw-ear structure, where mammals are defined as having (1) a dentary-squamosal suspensorium, (2) the articularquadrate joint not a mandibular suspensorium, (3) three middle ear bones, and (4) the

Detecting narwhal foraging behaviour from accelerometer and depth data using mixed-effects logistic regression

open access: yesAnimal Biotelemetry, 2023
Background Due to their Arctic habitat and elusive nature, little is known about the narwhal (Monodon monoceros) and its foraging behaviour. Understanding its ability to catch prey is essential for understanding its ecological role, but also to assess ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Impact of carnivory on human development and evolution revealed by a new unifying model of weaning in mammals [PDF]

open access: yes, 2012
Our large brain, long life span and high fertility are key elements of human evolutionary success and are often thought to have evolved in interplay with tool use, carnivory and hunting.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Drivers of spring migration phenology in Rocky Mountain elk

open access: yesScientific Reports
By migrating, ungulates take advantage of cyclical fluctuations in resources, which allows them to persist at greater population numbers than they would in the absence of these seasonal movements.
