Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis.
A recent study from UBC's Okanagan campus identifies new genetic markers in sockeye salmon that can help improve management of fish populations.
For humans, there are hundreds of antibodies available on the market today to evaluate immune status in health and diseases. However, for the more than 42 known species of dolphins around the world, commercially available marine-specific antibodies do not exist. With the drastic increase in the number of unusual dolphin strandings and deaths along the southeastern coast of the US and elsewhere, finding specific antibodies to test, monitor and document their immune health is critical.
A new species of a fossil pliosaur (large predatory marine reptile from the 'age of dinosaur') has been found in Russia and profoundly change how we understand the evolution of the group, says an international team of scientists.
Zika virus infection passes efficiently from a pregnant monkey to its fetus, spreading inflammatory damage throughout the tissues that support the fetus and the fetus's developing nervous system, and suggesting a wider threat in human pregnancies than generally appreciated, University of Wisconsin-Madison researchers have found.
The invasion of nonnative species has widespread and detrimental effects on local and global ecosystems. These intruders often spread and multiply prolifically, displace native species, alter the intended interactions between flora and fauna, and damage the environment and economy. In a paper publishing in the SIAM Journal on Applied Mathematics, Qihua Huang, Hao Wang, and Mark Lewis present a continuous-discrete hybrid population model that describes the invasive dynamics of zebra mussels in North American rivers.
Human social groups have a strange tendency to share responsibility for taking care of infants; parents, older siblings, and other adult relatives all help to nurture babies. The only other primates that take care of infants this way are marmosets, a group of small, highly social monkeys from South America. In another striking parallel to humans, infant marmosets also benefit from frequent feedback while learning their vocal calls, researchers report in Current Biology.
Mountain-dwelling East African honey bees have distinct genetic variations compared to their savannah relatives that likely help them to survive at high altitudes, report Martin Hasselmann of the University of Hohenheim, Germany, Matthew Webster of Uppsala University, Sweden, and colleagues May 25, 2017, in PLOS Genetics.
UC Davis researchers have identified a genetic mutation in horses that should help identify horses that are at risk for squamous cell carcinoma of the eye and enable horse owners to make informed breeding decisions.
Blind cavefish typically have skulls that bend slightly to the left. A study by UC suggests this orientation might help them find food as they navigate in a perpetual counter-clockwise direction around a cave.
