Human interference in the deep sea could already be outpacing our basic understanding of how it functions. As a result, without increased research and an immediate review of deep ocean conservation measures, the creatures that live there face an uncertain future, Oxford University scientists have warned.
Brazilian free-tailed bats are expert flyers, capable of migrating hundreds of miles and regularly traveling more than 30 miles a night. But they pull up short at a narrow ocean channel that cuts across the Bahamas, dividing bat populations that last shared an ancestor hundreds of thousands of years ago.
For the first time, scientists have shown that a female fruit fly's pheromone signals can actually tell males how much energy her body has invested in egg production versus in storing away energy for her own survival. And it's a signal that she can't change in order to make herself more attractive.
In a recent report published in Nature Microbiology, University of Hawai'i at Mānoa (UHM) oceanography professor Ed DeLong and his team report the largest single-site microbiome gene catalog constructed to date. With this new information, the team discovered nutrient limitation is a central driver in the evolution of ocean microbe genomes.
Smithsonian scientists use sonar to estimate Antillean Manatee populations in the murky waters of Panama's internationally protected San San Pond Sak wetlands.
The discovery of a new Scandinavian longhorn beetle subspecies triggered a discussion on the vague classification rank. As a result, a newly proposed subspecies definition has been published along with the description of the taxon in the open access journal ZooKeys. To the authors, before being determined as a subspecies, a population needs to be deemed a potentially incipient new species, diagnosed by a minimum of one heritable trait and, at least, partially isolated geographically.
Scientists from Newcastle University, UK, say we need to improve our information about little-known species to reduce the risk of one going extinct just because no-one is interested in looking for it.
Invasive mussels and less nutrients from tributaries have altered the Lake Michigan ecosystem, making it more conducive to the stocking of lake trout and steelhead than Chinook salmon, according to a recent US Geological Survey and Michigan State University study.
A new marsupial-like carnivorous animal that lived more than 40 million years ago in what is now Turkey may have evolved in the absence of competition from placental mammals, according to a study published Aug. 16, 2017, in the open-access journal PLOS ONE by Murat Maga from University of Washington, US and Robin Beck from University of Salford, UK.
New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study published today in the journal Science Advances and led by the University of California, Davis. These technologies can be applied to a wide range of species around the world -- from mushrooms to walruses -- but the study focuses on two iconic species of Pacific salmon: steelhead and chinook.
