Tiny fraction of oceans could meet world's fish demand
Covering 70 percent of Earth's surface, the world's oceans are vast and deep. So vast, in fact, that nearly every coastal country has the potential to meet its own domestic seafood needs through aquaculture. In fact, each country could do so using a tiny fraction of its ocean territory.

Meadow of dancing brittle stars shows evolution at work
Newly-described fossil shows how brittle stars evolved in response to pressure from predators, and how an 'evolutionary hangover' managed to escape them.

Environmental Specimen Bank: Time capsule for the future
The Environmental Specimen Bank is an archive of environmental samples from the Norwegian nature. All data are saved in a database, which contains information about thousands of samples. And in the freezers, samples from fish, blue mussels, bird eggs, polar bears, arctic foxes, seals, otters, wolverines and reindeers – even mosses, air samples and sewage samples - are stored.

How urban seasnakes lost their stripes
Researchers studying turtle-headed seasnakes living on coral reefs in the Indo-Pacific noticed something unusual about the snakes' color patterns: seasnakes living in more pristine parts of the reef were decorated with black-and-white bands or blotches. Those in places with more human activity -- near the city or military activity -- were black. Those color differences are explained by differences in the snakes' exposure to pollution.

Marine noise pollution stresses and confuses fish
Increased noise pollution in the oceans is confusing fish and compromising their ability to recognise and avoid predators.

Sea urchins: From pest to plate
The genital gland of a sea urchin, the so-called gonad, is found inside the urchin. This organ stores nutrients, and contains milt and roe during the spawning season in spring. The gonads are very popular in sushi dishes in especially Asia, but also in other parts of the world.

Amateur collectors in Japan discover country's first and oldest fossil diving bird
Two brothers from a small town in Hokkaido, Japan, made the discovery of their lives -- the first and oldest fossil bird ever identified in their country. Identified as a new species, it has been named Chupkaornis keraorum.

The good, the bad and the algae
A new study is testing whether one of California’s largest and most polluted lakes can transform into one of its most productive and profitable. Southern California’s 350-square-mile Salton Sea has well-documented problems related to elevated levels of nitrogen and phosphorus from agricultural runoff. The research team intends to harness algae’s penchant for prolific growth to clean up these pollutants and stop harmful algae blooms while creating a renewable, domestic source of fuel.

Marine reserves a solution to bycatch problem in oceans
Commercial fishermen may be able to catch more of the profitable fish they want with marine reserves than without them, according to a study.

DNA from Viking cod bones suggests 1,000-year history of European fish trade
New research using DNA from the fish bone remains of Viking-era meals reveals that north Norwegians have been transporting -- and possibly trading -- Arctic cod into mainland Europe for a millennium.

A dolphin diet
The health of dolphin populations worldwide depends on sustained access to robust food sources. Marine biologists have now studied the diets of dolphin species to understand the animals' foraging habits and how they share ocean resources.

Microscopic body snatchers infest our oceans
Predatory microbes which enslave prey to acquire photosynthetic capability are abundant in our oceans, according to new research.

Changes in biodiversity: Better assessment
Assessing the state of an ecosystem solely on the basis of short-term changes in the number of different species it contains can lead to false conclusions.

Ecosystem cascades affecting salmon
New research reveals that shifts in ocean conditions in the Gulf of the Farallones leads to changes in bird predation, affecting the number of California salmon that return as adults.

Understanding how fishers fish on coral reefs can inform fishery management strategies
A study of spearfishing on a Caribbean coral reef illustrates how understanding the process of fishing can help in developing management strategies to address overfishing and coral reef protection worldwide. Understanding which fish are targeted, when, why and where in a coral reef habitat, are important details that extend beyond catch limits or even bans that so often define fishing regulations.

New system could remove two water pollutants from agricultural fields
Algae blooms in the Gulf of Mexico use up the majority of the oxygen in the water, leading to massive "dead zones" that cannot support fish or other wildlife. The culprit? Nitrate, running off agricultural fields through tile drainage systems. But nitrate is only part of the problem. Algae in freshwater lakes and ponds flourishes when exposed to a different pollutant, phosphorus, and the tiniest amount is enough to trigger a bloom.

Coral disease outbreaks fluctuate with El Niño years, new research finds
Disease outbreaks in corals have followed El Niño-fueled coral bleaching events in the past, leading to speculation about the connection between the diseases and the El Niño cycles. This new study confirms the speculation.

The new yellow sea snake assumes an unusual ambush posture
Carrying its petite frame and all-yellow skin, the recently scrutinized sea snake populations from Golfo Dulce, Costa Rica, already seem different enough to be characterized as a new subspecies. However, their most extraordinary trait is only exposed at night when the serpents go hunting for small fish as they hang upside down just below the water surface assuming a peculiar sinusoidal ambush posture.
