New era of fisheries policy needed to secure nutrition for millions
A new study argues that for fisheries policies to be effective they must take in to account not just fish stock conservation and environmental issues, but also research data on the patterns and dynamics of fish trade, markets and user consumption.

Coral reef fishes prove invaluable in the study of evolutionary ecology
Coral reef fish species have proven invaluable for experimental testing of key concepts in social evolution and already have yielded insights about the ultimate reasons for female reproductive suppression, group living, and bidirectional sex change.

Paleontology: The eloquence of otoliths seen in a 23-million-year-old fish fossil
Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes.

Actor Johnny Depp immortalized in name of fossilized creature with 'scissor hand' claws
A scientist has discovered an ancient extinct creature with 'scissor hand-like' claws in fossil records and has named it in honor of his favourite movie star. The 505-million-year-old fossil called Kooteninchela deppi, which is a distant ancestor of lobsters and scorpions, was named after the actor Johnny Depp for his starring role as Edward Scissorhands -- a movie about an artificial man named Edward, an unfinished creation, who has scissors for hands.

H1N1 discovered in marine mammals
Scientists detected the H1N1 (2009) virus in free-ranging northern elephant seals off the central California coast a year after the human pandemic began.

'Fish thermometer' reveals long-standing, global impact of climate change
Climate change has been impacting global fisheries for the past four decades by driving species towards cooler, deeper waters, according to scientists.

Fossil saved from mule track revolutionizes understanding of ancient dolphin-like marine reptile
Scientists have revealed a new species of ichthyosaur (a dolphin-like marine reptile from the age of dinosaurs) from Iraq, which revolutionizes our understanding of the evolution and extinction of these ancient marine reptiles.

Cooling ocean temperature could buy more time for coral reefs
Limiting the amount of warming experienced by the world's oceans in the future could buy some time for tropical coral reefs, say researchers.

From ocean to land: The fishy origins of our hips
New research has revealed that the evolution of the complex, weight-bearing hips of walking animals from the basic hips of fish was a much simpler process than previously thought.
-
Microbes capture, store, and release nitrogen to feed reef-building coral
Microscopic algae that live within reef-forming corals scoop up available nitrogen, store the excess in crystal form, and slowly feed it to the coral as needed, according to a study published in mBio.
-
Corals turn to algae for stored food when times get tough
Researchers present new evidence for the crucial role of algae in the survival of their coral hosts. Ultra-high resolution images reveal that the algae temporarily store nutrients as crystals, building up reserves for when supplies run low.

Seabird bones reveal changes in open-ocean food chain
Remains of endangered Hawaiian petrels -- both ancient and modern -- show how drastically today's open seas fish menu has changed. Scientists analyzed the bones of Hawaiian petrels -- birds that spend the majority of their lives foraging the open waters of the Pacific. They found that the substantial change in petrels' eating habits, eating prey that are lower rather than higher in the food chain, coincides with the growth of industrialized fishing.

Using earthquake sensors to track endangered whales
Oceanographers used data from seafloor seismometers to analyze more than 300,000 fin-whale calls. By triangulating the position they created more than 150 tracks off the Pacific Northwest coast.
-
Under-appreciated benefit of oyster restoration highlighted
A new study shows that healthy oyster reefs would help to buffer the increasing acidity of coastal waters.

Coral reefs suffering, but collapse not inevitable
Coral reefs are in decline, but their collapse can still be avoided with local and global action. That's according to findings based on an analysis that combines the latest science on reef dynamics with the latest climate models.
