Researchers at IMDEA Networks (Spain) in collaboration with University of Haifa (Israel) have developed an underwater acoustic system for the localization of marine mammals, underwater vehicles and other sound sources in the ocean, using no more than a single hydrophone (basically an underwater microphone) as a receiver.
Mussels protect themselves against environmental disturbances and enemies through a hard, calcareous shell. Increased ocean acidification makes it difficult for organisms to form their shells. In a study published today, in the international journal, Nature Communications, a group of scientists from the Kiel University and GEOMAR Helmholtz Centre for Ocean Research Kiel show that mussel larvae react sensitively to ocean acidification, which leads to reduced calcification rates and shell dissolution.
Large, physically strong Masu salmon disperse farther when infected with parasites, potentially escaping from further infections at the contaminated site but ironically resulting in the greater expansion of the parasite, according to Hokkaido University researchers.
Natural habitats play a vital role in helping other plants and animals resist heat stresses ramping up with climate change -- at least until the species they depend on to form those habitats become imperiled.
Aerial drone footage of bowhead whales in Canada's Arctic has revealed that the large mammals molt and use rocks to rub off dead skin.
Due to climate change, including rising temperatures, more and more methane is bubbling up from lakes, ponds, rivers and wetlands throughout the world. The release of methane -- a potent greenhouse gas -- leads to a further increase in temperature, thus creating a positive feedback loop (also known as a 'vicious circle'). This is the conclusion of a team of biologists led by Radboud University in an article published in Nature Communications on Nov. 22.
Bowhead whales molt and rub on large rocks -- likely facilitating exfoliation -- in coastal waters in the eastern Canadian Arctic during late summer, according to a study published Nov. 22, 2017, in the open-access journal PLOS ONE by Sarah Fortune from University of British Columbia, Canada, and colleagues.
Three new research studies from the University of Texas at Arlington have found harmful pathogenic bacteria in Texas groundwater near unconventional natural gas extraction sites.
A special publication titled "Planetary Biodiversity Inventory (2008-2017): Tapeworms from the Vertebrate Bowls of the Earth," just published by the University of Kansas Museum of Natural History.
In a school of rummy-nose tetras, a common aquarium fish, group coordination appears to occur by each fish continuously changing which of its neighbors it pays attention to, according to new research published in PLOS Computational Biology.
