A new genetic analysis of Southern Resident killer whales found that two male whales fathered more than half of the calves born since 1990 that scientists have samples from, a sign of inbreeding in the small killer whale population that frequents Washington's Salish Sea and Puget Sound.
The pin mold fungus Phycomyces blakesleeanus forms a dense forest of vertically growing fruiting bodies, but how does it know which way is 'up'? New research publishing April 24 in the open-access journal PLOS Biology, from Gregory Jedd's group at the Temasek Life Sciences Laboratory, National University of Singapore, reveals that the fungi have acquired and re-modeled a gene from bacteria to help them make large gravity-sensing crystals.
A new WCS paper published in the journal BioScience finds that the enormous trends toward population stabilization, poverty alleviation, and urbanization are rewriting the future of biodiversity conservation in the 21st century, offering new hope for the world's wildlife and wild places.
Unlike most hermit crabs, the blanket-hermit crab does not use empty shells for protection, and instead lives symbiotically with a sea anemone. The crab uses the anemone to cover its soft abdomen, and can pull the anemone's tissue over its head to protect itself whenever necessary. Since 1888, this crab had been considered a unique species until a research team recently described five new ones and a new genus in the open access journal ZooKeys.
Sonification of 10 years of oceanic migration of these seals reveals coordinated swimming.
Warmer springs create a 'mismatch' where hungry chicks hatch too late to feast on abundant caterpillars, new research shows.
Both online repositories the Atlas of Living Australia (ALA) and the Global Biodiversity Information Facility (GBIF) were found to 'lose and confuse' portions of the data provided to them, according to an independent audit of ca. 800,000 records from three Australasian museums. Genus and species names were found to have been changed in up to 1 in 5 records, and programming errors caused up to 100 percent data loss in some data categories.
An international consortium of scientists is proposing a massive project to sequence, catalog and analyze the genomes of all eukaryotic species on the planet, an undertaking the researchers say will take 10 years, cost $4.7 billion and require more than 200 petabytes of digital storage capacity. Eukaryotes include all organisms except bacteria and archaea. There are an estimated 10-15 million eukaryotic species on Earth.
Researchers have used a scanner designed for rockets to collect the first-ever computed tomography (CT) scan of an entire minke whale. By combining the CT scan results with custom-developed computer simulation tools, the researchers model how the whales hear sounds produced by other whales or by human-created (anthropogenic) sources such as ship propellers.
The Experimental Biology 2018 meeting (EB 2018) will showcase exciting new research aimed at understanding contamination and improving the environment.
