European wildcats, thought to be extinct 50 years ago in the Jura mountains, have since recolonised part of their former territory. This resurgence in an area occupied by domestic cats has gone hand-in-hand with genetic crosses between the two species. A team of biologists from the University of Geneva modelled the interactions between the two species and predict that hybridisation will entail the irreversible genetic replacement of wildcats.
In a recent study, researchers from Thailand's Suranaree University of Technology and the Xishuangbanna Tropical Botanical Garden (XTBG) revealed a worrying situation where a huge number of reptile species are being exploited, with little international regulation, implying a lack of reliable a priori estimates of the impact on wild populations.
Concentrate on your own task but also pay attention to others--this is the key rule for success, at least for rats when exploring as a group The rat in a maze might be one of the most classic paradigms in the study of behaviour, but an international team of scientists has put a twist on this experimental motif to push the leading edge of technology and research into search strategies of collectives.
New University of Guelph research has found that feeding cats one large meal a day may help control hunger better than feeding them several times a day.
Most wild animals show a suite of predator avoidance behaviors such as vigilance, freezing, and fleeing. But these are quickly reduced after the animals come into contact with humans through captivity, domestication, or urbanization, according to a study led by Benjamin Geffroy from MARBEC (Institute of Marine Biodiversity, Exploitation and Conservation), publishing September 22nd in the open-access journal PLOS Biology.
A study of search and rescue dogs led by the School of Veterinary Medicine showed little difference in longevity or cause of death between dogs at the disaster site and dogs in a control group.
Some of the genetic differences that have arisen between domesticated chickens and their wild ancestors, the red junglefowl, are linked to epigenetic changes, according to a new study published in Nature Ecology & Evolution. Scientists at Linköping University, Sweden, have discovered a small number of "hotspots" in the DNA that control epigenetic changes at hundreds of other locations throughout the genome.
Clemson researchers collaborated on a paper titled 'Variants in FtsJ RNA 2?-O-Methyltransferase 3 and Growth Hormone 1 are associated with small body size and a dental anomaly in dogs.'
A new study of older pet dogs found that problem solving, sociability, boldness and dependency decline with age, and reported no associations between an enriched diet, lifelong training experiences, and measures of behavior and cognition after a one-year diet period. A team of researchers at the University of Veterinary Medicine, Vienna, Austria, and University of Liverpool, UK present these findings in the open-access journal PLOS ONE on September 16, 2020.
A genetic mutation might be the reason dogs with hypothyroidism are less likely to develop T-zone lymphoma (TZL). That's the finding from Morris Animal Foundation-funded researchers at Colorado State University who tried to identify genetic risk factors for TZL using a genome-wide association study (GWAS) and subsequent targeted sequencing. They recently published their results in the journal BMC Genomics.
