Scientists discover cacophony of fish ‘farts, burps and coughs’

University of Victoria — Fish air movement sounds—farts, burps and coughs—are music to fish ecologists’ ears when it comes to discovering biological sounds in freshwater habitats, giving scientists a better understanding of aquatic ecosystems and potential threats from human-caused noises. In one of the largest surveys of its kind published in open-access journal PLOS ONE, Read More…

Immune-system cells of fish are ingesting plastic…and then dying

William and Mary University — It’s become an all-too-common variety of news story: Dead whales whose digestive systems are clogged with plastic. Increasing numbers of seabirds eating plastic, often with dire consequences. Ditto with turtles and fish. Plastic ingestion by aquatic life is well documented. Less well known is the damage plastic does to the immune systems of Read More…

Global warming of oceans will make some fish bigger, Irish…

Irish Mirror — The global warming of oceans will make some fish balloon bigger in size, new research has found. Scientists probing the effects of climate change have now discovered that for every one degree change, sizes could fluctuate by up to 40%. While most species will get smaller, 45% will get bigger. This new finding puts a line through previous studies that claimed all fish Read More…

A.I. is helping scientists understand an ocean’s worth of data

The New York Times — If you had about 180,000 hours of underwater recordings from the Pacific Ocean, and you needed to know when and where, in all those different hours, humpback whales were singing, would you Google it? That is what Ann Allen, a research ecologist at the National Oceanic and Atmospheric Administration, did. Sort of. In January 2018, she approached Google and asked if they Read More…

World’s oceans are capturing twice as much carbon as previously…

Daily Mail — A biological ‘pump’ that distributes carbon to the bottom of the ocean via tiny plankton is operating twice as rapidly as previously thought, a new study claims. US scientists say that the level of carbon that is distributed to the ocean floor depends on how much sunlight a microscopic type of plankton gets. This phytoplankton, which consumes carbon dioxide and releases Read More…

Nuclear Bombs Could Reveal How Old Whale Sharks Are For The First Time

Tech Times — These unusual creatures are whale sharks and other endangered species that live in tropical waters. Many people know a little about these marine giants: Whale sharks consume plankton and make a yearly migration to Australia. But there is an essential detail about these animals that has wholly eluded researchers: Their age. Like other sharks and rays, whale sharks don't have Read More…

Birds seen bating fish with bread as climate change causes new…

The Herald Scotland — Climate change is making birds adopt extraordinary behaviours to survive, according to new research. They include baiting fish with bread, attacking prey with the help of a train and using boats as hunting platforms. Others have been seen opening packets of sugar on cafe terraces and dropping mussels on to hard rocks to break the shell. The innovative tactics seen Read More…

New genetic tools promise to unlock secrets of microscopic marine life

Science — ifty percent of the oxygen we breathe comes from ocean microbes. Yet these tiny marine organisms have largely remained a mystery to science. Now, thanks to the efforts of more than 100 researchers around the globe, scientists have found a way to unlock the genomes of a handful of these creatures by genetically engineering their DNA. The study “will propel advances in plankton Read More…

Invasive species with charisma have it easier

ScienceDaily — It's the outside that counts: Their charisma has an impact on the introduction and image of alien species and can even hinder their control. An international research team, led by the Biology Centre of the Czech Academy of Sciences and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB), have investigated the influence of charisma on the management of invasive Read More…

Scientists Just Discovered Penguins Actually ‘Talk’ Under Water

ScienceAlert — Penguins, like all seabirds, are known to be highly vocal on land where they come to breed. They use these vocalisations to help them recognise their mate and kin. Outside of the breeding season, seabirds spend most of their life at sea and are adapted to the marine environment where they feed. Penguins are very unique among seabirds for their extreme diving abilities. They Read More…
