Chapman University has published new research showing how hagfishes survive an initial attack from predators before they release large volumes of slime to defend themselves. Because the slime is released after they are attacked, this defense strategy is only effective if they survive the initial bite. Results show that hagfish skin is not puncture resistant; it is both unattached and flaccid, which helps avoid internal damage from penetrating teeth.
Researchers at Scripps Institution of Oceanography at the University of California San Diego have made a discovery with potential human health impacts in a parchment tubeworm, found to have ferritin with the fastest catalytic performance ever described.
Tara C. Smith, Ph.D., a professor of epidemiology in Kent State's College of Public Health, published the findings of a study her lab conducted in 2015 that shows a higher-than-expected prevalence of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) at beaches around Lake Erie.
Environmental models are showing that the effects of climate change could be much stronger by the middle of the 21st century, and a number of ecosystem and weather conditions could consistently decline even more in the future.
Goannas have overtaken foxes as the number one predator of the endangered loggerhead turtle at its second largest Queensland nesting beach. A University of Queensland study has found that since feral red foxes were controlled in the 1980s, there has been an increase in the number goanna raids on loggerhead turtle nests at Wreck Rock beach, south of Agnes Waters.
Scientists working to protect California's most endangered salmon say in a new report that key improvements in tracking Sacramento River winter-run Chinook through California's complex water delivery system would help recover the species while the water continues to flow.
Fish cannot see ultraviolet B rays but still change their behavior when they grow up under increased UVB intensity. According to studies by biologists at the University of Bonn on three-spined sticklebacks (Gasterosteus aculeatus), increased UVB leads to a smaller body size and more risk-seeking behavior when faced with predators. Climate change is likely to increase UVB intensity, possibly with consequences for ecosystems and fish farming.
The conversion of tropical forests to crop and pastureland has long been a concern for scientists, a new study points to another unexpected consequence: changes in fish production.
NOAA scientists studying sounds made by Atlantic cod and haddock at spawning sites in the Gulf of Maine have found that vessel traffic noise is reducing the distance over which these animals can communicate with each other. As a result, daily behavior, feeding, mating, and socializing during critical biological periods for these commercially and ecologically important fish may be altered, according to a study published in Nature Scientific Reports.
University of Sydney researchers surveyed more than 500 visitors to an aquarium 'shark tunnel' to understand how attitudes to sharks and government shark policies can change.
