Marine heatwaves decimate sea urchins, mollusks and more at Rottnest
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as mollusks and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 percent bet.....»»
Eight new deep-sea species of marine sponges discovered
Although marine sponges are widespread in the oceans, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study by Julio A. Díaz and colleagues, published in PeerJ, reveal.....»»
Research reveals novel herpesvirus in South American pinnipeds

New deep-sea worm discovered at methane seep off Costa Rica
Greg Rouse, a marine biologist at UC San Diego's Scripps Institution of Oceanography, and other researchers have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica. R.....»»
Conservation actions for South Africa"s white shark population now a matter of urgency, say researchers
A group of marine biologists specializing in shark ecology, genetics and fisheries have challenged the findings from a recent study suggesting that South Africa's white shark population has not decreased, but simply redistributed eastwards to flee pr.....»»
Microalgae with unusual cell biology could lead to improved understanding of harmful algal blooms
What are the molecular processes in a unicellular marine algae species that can cause harmful algal blooms? A research team led by microbiologist Prof. Dr. Ralf Rabus from the University of Oldenburg (Germany) has conducted the first detailed analyse.....»»

Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era
Paleontologists have discovered a strange new species of marine lizard with dagger-like teeth that lived near the end of the age of dinosaurs. Their findings, published in Cretaceous Research, show a dramatically different ocean ecosystem to what we.....»»
After decades of Arctic sea ice getting faster, models suggest a dramatic reversal is coming
Will ice floating in the Arctic Ocean move faster or slower over the coming decades? The answer to this question will tell us whether marine transportation can be expected to get more or less hazardous. It might also have important implications for t.....»»
Less ice in the Arctic ocean has complex effects on marine ecosystems and ocean productivity, study finds
Over the past 25 years, the amount of summer Arctic sea ice has diminished by more than 1 million square kilometers. As a result, vast areas of the Arctic Ocean are now, on average, ice-free in summer. Scientists are closely monitoring how this impac.....»»
How melting Arctic ice leads to European drought and heatwaves

Team finds novel vehicle for antibiotic resistance
Antibiotic resistance is a significant and growing medical problem worldwide. Researchers at the Marine Biological Laboratory (MBL) and collaborators have found a novel genetic arrangement that may help a common bacterium in the human gut, Bacteroide.....»»
Fewer fish, worse health: The climate effect
Over the next 25 years, reduced intake of marine food resources due to climate change will likely have a negative impact on the cardiovascular health of First Nations on Canada's Pacific coast, a new study suggests......»»

A lightweight fish pen to move farms to deeper seas
The University of Queensland has co-led a project to design a cost effective yet robust pen to expand fish farming into deeper ocean areas to help feed the growing global population. The research is published in the Journal of Marine Science and Engi.....»»
The Golgi organelle"s ribbon structure is not exclusive to vertebrates, contrary to previous consensus
Researchers report February 29 in the journal Cell Reports that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins......»»
New findings suggest convergent evolution of algal CO₂-fixing organelles
Researchers at the University of Tsukuba identified the proteins of a CO2-fixing organelle, namely, "pyrenoid," in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independ.....»»
Findings in Australia unveil fossil trove of Cambrian mollusks
A team of researchers led by Alexander Pohle has unveiled a treasure trove of ancient fossils from Queensland, Australia's Black Mountain. The findings, published in PeerJ, shed new light on the complex three-dimensional siphuncle morphology of Plect.....»»
Researchers are first to see at-risk bat flying over open ocean
