New tool enables Nova Scotia lobster fishery to address impacts of climate change
on October 11, 2019 at 7:53 pm
Researchers use long-term survey data sets and climate models to help fishing communities plan for a warmer ocean. Researchers have developed a tool that incorporates projected changes in ocean climate onto a geographic fishery management area. Now fishermen, resource managers, and policy-makers can use it to plan for the future sustainability of the lobster fishery in Nova Scotia and Canadian waters of the Gulf of Maine.
Scientists 'must be allowed to cry' about destruction of nature
on October 10, 2019 at 6:21 pm
Scientists witnessing the destruction of the natural world must be supported and 'allowed to cry,' researchers say.
Solution to Ice Age ocean chemistry puzzle
on October 10, 2019 at 1:57 pm
New research into the chemistry of the oceans during ice ages is helping to solve a puzzle that has engaged scientists for more than two decades. At issue is how much of the CO2 that entered the ocean during ice ages can be attributed to the 'biological pump', where atmospheric carbon is absorbed by phytoplankton and sequestered to the seafloor as organisms die and sink.
Infectious disease in marine life linked to decades of ocean warming
on October 9, 2019 at 8:24 pm
New research shows that long-term changes in diseases in ocean species coincides with decades of widespread environmental change.
Reef fish caring for their young are taken advantage of by other fish
on October 9, 2019 at 5:24 pm
Among birds, the practice of laying eggs in other birds' nests is surprisingly common. This phenomenon, known as brood parasitism, was unknown in coral reef fish because most marine fish don't provide any parental care at all. Now, however, biologists studying an unusual kind of coral reef fish that does care for its young have found that, sure enough, other fish are taking advantage of this to get free parental care for their offspring.
Hush, little baby: Mother right whales 'whisper' to calves
on October 9, 2019 at 5:23 pm
A recent study explores whether right whale mother-calf pairs change their vocalizations to keep predators from detecting them.
A unique study sheds light on the ecology of the glacial relict amphipod Gammaracanthus lacustris
on October 9, 2019 at 2:11 pm
The glacial relict amphipod Gammaracanthus lacustris only occurs in deep and cold waters. A new study produced new information on the life cycle and ecology of this rare amphipod. G. lacustris is adapted to cold water and would probably not survive in rising water temperatures due to climate change.
Study recommends special protection of emperor penguins
on October 9, 2019 at 1:21 am
Researchers recommend additional measures to protect and conserve one of the most iconic Antarctic species -- the emperor penguin (Aptenodyptes forsteri).
The deeper these octopuses live, the wartier their skin
on October 8, 2019 at 4:45 pm
Deep beneath the ocean's surface, surprisingly cute pink octopuses creep along the seafloor. Some of them have super warty skin, and some are smooth. Scientists weren't sure if these octopuses were even members of the same species, and they didn't know how to explain the differences in the animals' looks. But a new study shows that the deeper in the ocean the octopuses live, the bumpier their skin and the smaller their bodies.
Proximity to paths and roads is a burden for white-tailed sea eagles
on October 7, 2019 at 2:04 pm
A research team has now measured concentrations of the hormone corticosterone and its metabolic products in white-tailed sea eagles in northern Germany and correlated these values with potential causes of stress. They found that the levels of corticosterone in the birds' urine are higher the closer a breeding pair's nest is to paths or roads.
Anesthetizing fish may affect research outcomes
on October 5, 2019 at 5:40 pm
Fish use colorful patterns to signal to each other, including advertising for mates and warding off rivals. Studying the relationship between color and behavior sometimes entails anesthetizing and photographing the fish, but anesthetics may alter coloration, influencing the traits researchers are trying to study.
Scientists uncover genetic similarities among species that use sound to navigate
on October 4, 2019 at 2:56 pm
Insect-eating bats navigate effortlessly in the dark and dolphins and killer whales gobble up prey in murky waters thanks in part to specific changes in a set of 18 genes involved in the development of the cochlear ganglion -- a group of nerves that transmit sound from the ear to the brain, according to a new study.
Seafood consumption during pregnancy may improve attention capacity in children
on October 2, 2019 at 10:11 pm
A new study highlights the importance of eating a diet rich in lean and fatty fish during the first months of pregnancy.
Besides hot water, coral bleaching also about location, location, location
on October 2, 2019 at 8:52 pm
A new study revealed a more complex view than current standard predictions of coral bleaching events caused primarily by heat stress; rather, the scientists found that bleaching is driven by a variety of stressors, and each region responds differently.
Seagrass meadows harbor wildlife for centuries, highlighting need for conservation
on October 2, 2019 at 6:53 pm
Seagrass meadows put down deep roots, persisting in the same spot for hundreds and possibly thousands of years, a new study shows. Researchers used modern and fossil shells from seagrass-dwelling animals to estimate the age of these meadows, showing that, far from being transient patches of underwater weeds, they are remarkably stable over time.
New imaging platform examines mechanisms behind coral bleaching
on October 2, 2019 at 6:42 pm
A non-invasive approach could help marine biologists monitor coral health in the face of climate change.
Warming impedes a coral defense, but hungry fish enhance it
on October 2, 2019 at 6:42 pm
Corals exude chemical defenses against bacteria, but when heated in the lab, those defenses lost much potency against a pathogen common in coral bleaching. There's hope: A key coral's defense was heartier when that coral was taken from an area where fishing was banned and plenty of fish were left to eat away seaweed that was overgrowing corals elsewhere.
Safeguarding the world's largest tuna fishery
on October 2, 2019 at 3:03 pm
New research has used a combination of records from captains and scientific observers, FAD tracking data, ocean models and cutting edge simulation methods to reveal for the first time the trajectories and potential impact FADs may have on fisheries around Pacific island nations.
Fossil fish gives new insights into evolution after end-Cretaceous mass extinction
on October 2, 2019 at 3:03 pm
An international research team has discovered a new and well-preserved fossil stingray with an exceptional anatomy, which greatly differs from living species. The find provides new insights into the evolution of these animals and sheds light on the recovery of marine ecosystems after the mass extinction occurred 66 million years ago.
Inspired by northern clingfish, researchers make a better suction cup
on October 2, 2019 at 2:28 pm
Scientists, inspired by the clingfish's suction power, set out to develop an artificial suction cup that borrows from nature's design. Their prototype actually performed better than the clingfish.
