Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton.

The study, reported in the journal Scientific Reports published by Nature, found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

New fossils found in Northeastern China have revealed a remarkable evolutionary coincidence: an extinct group of insects known as Kalligrammatid lacewings (Order Neuroptera) share an uncanny resemblance to modern day butterflies (Order Lepidoptera). Even though they vanished some 50 million years before butterflies appeared on earth, they possess the same wing shape and pigment hues, wing spots and eyespots, body scales, long proboscides, and similar feeding styles as butterflies.

A photo of the modern owl butterfly (“Caligo Memnon”) shown beside a fossilized Kalligrammatid lacewing (“Oregramma illecebrosa”) shows some of the convergent features independently evolved by the two distantly-related insects, including wing eyespots and wing scales.

In an incredible example of convergent evolution, both butterflies and kalligrammatids evol

The first Britain-wide assessment of the value of wild flowers as food for pollinators shows that decreasing resources mirror the decline of pollinating insects.

When the moon is high in the sky, it creates bulges in the planet’s atmosphere that creates imperceptible changes in the amount of rain that falls below. New University of Washington research to be published in Geophysical Research Letters shows that the lunar forces affect the amount of rain – though very slightly.

The mosquito-borne Zika virus has been linked to a surge in cases of birth defects in Brazil, and is spreading in other countries in the southern hemisphere. Flaminia Catteruccia, associate professor of immunology and infectious diseases at Harvard T.H. Chan School of Public Health, says the virus may have adapted to the human environment and mutated.

A new global analysis of seafood found that fish populations throughout the world's oceans are contaminated with industrial and agricultural pollutants, collectively known as persistent organic pollutants (POPs). The study from researchers at Scripps Institution of Oceanography at UC San Diego also uncovered some good news?concentrations of these pollutants have been consistently dropping over the last 30 years.

Flint, Michigan temporarily switched its water supply from Lake Huron to the Flint River in April 2014 to cut costs. Should officials have known that lead contamination would result?

The eastern gray whales that commonly appear along the West Coast of the United States seemingly have recovered from over-hunting with new protective guidelines established in the 1970s. Their counterparts across the ocean – western gray whales – have not fared as well.

Some scientists believe that a lack of prey may be a limiting factor in the recovery of western gray whales, which number fewer than 200 in their feeding area near Russia’s Sakhalin Island. For years, researchers were unable to assess the growth of whale prey in the region because of the remote location, inaccessible conditions of winter ice cover, and the rugged weather that prevented winter sampling.

However, researchers from Russia and the United States studied an inch-long crustacean, Ampelisca eschrichtii, an amphipod that is a favorite food of the western gray whale, in samples that were collected from the Sakhalin Shelf between late spring and early fall over six years between 2002 and 2013. The research team found enough information in the limited samples to assess the missing winter-life history of these amphipods and to document their great abundance and production.

If you’re an aquarium enthusiast, you no doubt have many beautiful and colorful tropical fish populating your aquarium. Perhaps you’ve studied the different species carefully to be sure they can peacefully co-exist. You know what they like to eat and what water conditions help them thrive.

Here’s a question though — did you investigate to see whether the type of fish you wanted to buy is in danger in its natural habitat? Did you ask whether it was captive-bred? 

An analysis of long-term, water quality monitoring data reveals that climate change is already having an impact on ecosystems in the coastal waters of Buzzards Bay, Mass. The impacts relate to how nitrogen pollution affects coastal ecosystems.

Utilizing 22 years of data collected by a network of citizen scientists, researchers from the Woods Hole Oceanographic Institution (WHOI) and their colleagues at the Buzzards Bay National Estuary Program, the Buzzards Bay Coalition, and the Marine Biological Laboratory found that average summertime temperatures in embayments throughout Buzzards Bay warmed by almost 2 degrees Celsius—roughly 4 degrees Fahrenheit.

"That is a rapid temperature increase for marine life," said Jennie Rheuban, a research associate at WHOI and lead author of the paper published January 15, 2016, in the journal Biogeosciences. "For some species, a single degree Fahrenheit change can mean the difference between a comfortable environment and one where they can no longer thrive."
