New species of beaked whale confirmed by DNA
Biologists have identified a rare new species of beaked whale that ranges from northern Japan across the Pacific Ocean to Alaska's Aleutian Islands.

New marine invertebrate species in Weddell Sea, Antarctica
The cold waters in Weddell, in the Antarctic ocean, are the environment in which a new marine invertebrate species -- the nudibranchs Doto carinova -- has been found.

Less fertilizer good news for the Great Barrier Reef
Researchers have shown a way to potentially halve the amount of fertilizer dairy farmers use while maintaining pasture yields, providing improved protection for the Great Barrier Reef.

Before animals, evolution waited eons to inhale
Time to smash the beaker when thinking about oxygen concentrations in water, at the time when animal life first evolved. Oceans stacked oxygen here and depleted it there, as a new novel model demonstrates. It may well toss a wrench into the way we have dated the evolution of the earliest animals.

New index reveals likelihood of terrestrial or aquatic lifestyles of extinct mammals
Researchers have developed a new index based on rib and body weight measurements that predicts whether a mammal lived on land, in water, or both. When applied to extinct mammalian species, the index showed that some could not have supported their own weight while walking or crawling, and thus must have been restricted to an aquatic life. The index reveals the habitats of extinct species and enables reconstruction of their lifestyles and the anatomical changes that accompanied adoption of an exclusively aquatic lifestyle.

Unusual new zoantharian species is the first described solitary species in over 100 years
A very unusual new species of zoantharian was just discovered. Although most zoantharians are colonial and many are known from coral reefs, the new species lives a solitary life in muddy habitats. This species is the first of its genus described in over 100 years.

Pathogenic bacteria hitchhiking on tiny plastic particles to North and Baltic Seas?
With increasing water temperatures comes an increasing likelihood of potentially pathogenic bacteria appearing in the North and Baltic Seas. Scientists have now demonstrated that a group of such bacteria known as vibrios can survive on microplastic particles.

A 'smart dress' for oil-degrading bacteria
The modified polyelectrolyte-magnetite nanocoating was applied to functionalize the cell walls of oil decomposing bacteria Alcanivorax borkumensis.

Scorpionfish too deep for SCUBA divers caught by submersible turns out to be a new species
Manned submersible Curasub, sneaking around the twilight depths of the Caribbean island of Curacao in search of currently unknown species, has found yet another new one. The newly discovered scorpionfish is the deepest-living member of its genus in the area. It also stands out in its appearance, including its colors.

Chemical pollution gets to Antarctic marine bird colonies
Latitude is the main factor which determines the organic pollutant concentration in Antarctic giant petrels – emblematic species in the Antarctic and sub-Antarctic regions – according to a new article.

Underwater terrain may be key factor in little auk foraging
Little auks forage in the same areas off East Greenland -- the continental shelf and its edge -- regardless of whether sea ice is present or absent, according to a new study.

Ocean acidification: The limits of adaptation
The most abundant single-celled calcifying alga of the world's oceans, Emiliania huxleyi is basically able to adapt to ocean acidification through evolution. However, the longest evolution experiment that has been conducted with this organism so far shows, that the potential for adaptation is not as large as initially expected. The growth rate under elevated carbon dioxide concentrations has not improved significantly after four years. Calcification was even lower than in today's cells from Emiliania huxleyi.

'Perfect storm' brought sea louse epidemic to BC salmon
High ocean temperatures and poor timing of parasite management likely led to an epidemic of sea lice in 2015 throughout salmon farms in British Columbia's Queen Charlotte Strait, a new study has found.

Medieval water power initiated collapse of salmon stocks
Salmon largely disappeared from our waters due to the construction of water mills, ecologists now conclude. The construction of water mills caused the destruction of the gravel beds in streams, making them unsuitable for salmon to spawn. Whereas it was previously thought that water contamination was the most likely explanation, archival research demonstrates that salmon stocks had already dwindled prior to the invention of the steam engine.

Zebrafish's growing impact on medical research
Zebrafish are becoming more and more popular as a research model for human disease. Along with mice and humans, they are one of the most commonly studied animals in biomedical research.

Paleontology: Aftermath of a mass extinction
A new study of fossil fishes from Middle Triassic sediments on the shores of Lake Lugano provides new insights into the recovery of biodiversity following the great mass extinction event at the Permo-Triassic boundary 240 million years ago.

Ancient rocks reveal how Earth recovered from mass extinction
Scientists have shed light on why life on Earth took millions of years to recover from the greatest mass extinction of all time.

For ancient deep-sea plankton, a long decline before extinction
A new study of nearly 22,000 fossils finds that ancient plankton communities began changing in important ways as much as 400,000 years before massive die-offs ensued during the first of Earth's five great extinctions. The research suggests that the effects of environmental degradation can be subtle until they reach a tipping point, at which dramatic declines in population begin.

Oceanographers grow, sequence genome of ocean microbe important to climate change
New light has been shed on a common but poorly understood bacteria known to live in low-oxygen areas in the ocean. By culturing and sequencing the microbe's entire genome, the oceanographers found that it significantly contributes to the removal of life-supporting nitrogen from the water in new and surprising ways.

Real reason turtles have shells: Burrowing tool
Scientists have discovered the real reason turtles have shells. While many thought turtle shells were for protection, new findings show that the shells were actually for digging underground to escape the harsh South African environment where these early proto turtles lived.
