Mockingbirds exposed to sub-lethal levels of lead in urban areas display significantly heightened aggression, said Morris Animal Foundation-funded researchers at Tulane University. The team said their findings highlight the possibility that sub-lethal lead exposure may be common among other wildlife living in urban areas and more work is needed to better understand its full effects. Their study was published in Science of the Total Environment.
Researchers in the University of Helsinki have identified two novel anxiety-related genomic regions in German Shepherd dogs. The region associated with fearfulness corresponds with the locus of human chromosome 18, which is associated with various psychiatric disorders, while the region associated with noise sensitivity includes several genes related to human and canine behaviour and mental disorders.
Emerging infectious diseases comprise a substantial fraction of important human infections, with potentially devastating global health and economic impacts. A 2008 paper in Nature described the emergence of no fewer than 335 infectious diseases in the global human population between 1940 and 2004. In the veterinary field, just as in the medical field, advanced molecular techniques and sophisticated computer-based algorithms for genetic sequence assembly and analysis have revolutionized infectious disease research.
New research by the University of Bristol in collaboration with Medical Detection Dogs has found that the best trained alert dogs have the potential to vastly improve the quality of life of people living with Type 1 diabetes.
The increase in opioid prescriptions for people over the past decade may have been paralleled by an increase in opioid prescriptions for pets, according to a study from researchers at the University of Pennsylvania's Perelman School of Medicine and the School of Veterinary Medicine. The findings, in this first-ever study of veterinary opioid prescriptions, suggest it is possible that misused veterinary prescriptions could contribute to the ongoing opioid epidemic.
In a new study published in the open-access journal PLOS Biology on Jan. 10, Sunitha Narasimha, Roshan Vijendravarma and colleagues report how fruit flies (Drosophila melanogaster), which lay eggs communally, use chemical deception to protect their eggs from being cannibalized by their own larvae.
Many cat owners worry about their pets wandering the streets, but perceive cats hunting mice and birds to be unavoidable instinct, researchers at the University of Exeter have found.
New research from the University of Liverpool and Mars Petcare's WALTHAM Centre for Pet Nutrition reveals overweight dogs are more likely to have shorter lives than those at ideal body weights.
Working with nine animal models, researchers find a preference for stability over energy conservation during speed-related gait transitions.
A better understanding of the way dogs communicate distress could be the first step in reducing the risk of dog bites for both children and adults, a new study has found.
