Climate shifts shorten marine food chain off California
Environmental disturbances such as El NiƱo shake up the marine food web off Southern California, new research shows, countering conventional thinking that the hierarchy of who-eats-who in the ocean remains largely constant over time.

Surprise new butterflyfish from the Philippine 'twilight zone'
A new species of striped Philippine butterflyfish -- the charismatic Roa rumsfeldi -- made a fantastic, 7,000-mile journey before surprising scientists with its unknown status. Live specimens collected from a depth of 360 feet escaped special notice until a single black fin spine tipped off aquarium biologists back in San Francisco.

Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report
Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.

DNA tests on albatross excrement reveal secret diet of top predator
A study that used DNA tests to analyse the scats of one of the world's most numerous albatrosses has revealed surprising results about the top predator's diet. DNA analysis of 1460 scats from breeding sites around the Southern Ocean has shown that the diet of black-browed albatrosses contains a much higher proportion of jellyfish than previously thought.

Keratin, proteins from 54-million-year-old sea turtle show survival trait evolution
Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54-million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.

Oysters offer hot spot for reducing nutrient pollution
Marine scientists have quantified potentially denitrifying bacteria in the oyster gut and shell, with important implications for efforts to reduce nutrient levels in coastal waters through oyster restoration.

Whales and dolphins have rich 'human-like' cultures and societies
Whales and dolphins (cetaceans) live in tightly-knit social groups, have complex relationships, talk to each other and even have regional dialects -- much like human societies. A major new study has linked the complexity of Cetacean culture and behavior to the size of their brains.

Bite on this: Alligators caught eating sharks
Jaws, beware! Alligators may be coming for you. A new study documents American alligators on the Atlantic and Gulf coasts are eating small sharks and stingrays. This is the first scientific documentation of a widespread interaction between the two predators.

Cocktail tests on toxic waste called for
Surprisingly low concentrations of toxic chemicals -- from fungicides to antidepressants -- can change the way some aquatic creatures swim and feed, according to new research. In addition, depending on the cocktail of toxins they can produce unexpected results.
