Lens-containing eyes are a feature of surprisingly broad spectrum of organisms across the animal kingdom that represent a significant improvement of simple eye composed of just photoreceptor cells and pigment cells. It is apparent that such an upgrade of animal visual system has originated numerous times during evolution since many distinct strategies to enhance light refraction through the use...

A greater one-horned Asian rhinoceros (Rhinoceros unicornis) presented for presumed ocular trauma to the left eye, with secondary bacterial infection, resulting in severe and progressive corneal ulceration. Following a poor response to medical therapy, the animal was anesthetized for further examination, and a bulbar conjunctival pedicle graft performed. This graft failed by 48-h postsurgery as...

Animal-assisted interventions have shown promising benefits in different populations such as children with cerebral palsy or autism spectrum disorder. Human–animal interaction leads to physical, cognitive, and emotional the child. The aim of current pilot study was evaluate effects a dog-assisted education program on postural, oculomotor, linguistic autonomy dimensions affected by severe multip...

Records on 65,536 Landrace pigs collected between 1985 and 1999 in herds on the National Swine Registry STAGES program were used to estimate additive genetic (animal), common environmental (litter), and residual variances and covariances for days to 250 lb, backfat, loin eye area, and lean growth rate. Analysis was by the REMLf90 program of I. Misztal using a multiple-trait animal model with fi...

BACKGROUND: The movement of animals makes them fascinating but difficult study subjects. Animal movements underpin many biological phenomena, and understanding them is critical for applications in conservation, health, and food. Traditional approaches t o animal tracking used field biologists wielding antennas to record a few dozen locations per ani· mal, revealing only the most general pattern...

Limulus has been a superb animal model for understanding vision in higher animals, including man. Nobel-prize winning research on the lateral eye of Limulus by H. K. Hartline revealed fundamental principles of retinal function applicable to all eyes. The function of the Limulus lateral eye is now well understood as is its essential role in the animal’s mating behavior.
