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.
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.
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.
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.
Scientists have developed a simple metric to capture the directional agreement between ocean currents and warming, revealing how ocean currents affect the range shift of marine biota in a changing climate.
Scientists at UCSB's NCEAS are transforming how complex marine data from the Ocean Health Index is synthesized, communicated and used for coastal management.
Oyster farmers are set to benefit from a new genetic tool that will help to prevent disease outbreaks and improve yields. The technology -- developed by scientists at the University of Edinburgh's Roslin Institute -- will enable hatcheries to rapidly assess the genetic make-up of their oysters, so they can select animals with desirable characteristics from which to breed.
A joint research led by HKBU and HKUST has assembled the 1.64 gigabytes genome of a deep-sea mussel, which is roughly equivalent to 50 percent of the size of human genome. This is the first decoded genome among all deep-sea macrobenthic animals, revealing a complete set of DNA.
A team of scientists have traced the evolution of whale size through more than 30 million years of history and found that very large whales appeared along several branches of the family tree about 2 to 3 million years ago. Increasing ice sheets in the Northern Hemisphere during this period likely altered the way whales' food was distributed in the oceans and enhanced the benefits of a large body size, the scientists say.
