Acidifying Oceans Could Hit California Mussels, a Key Species
Ocean acidification, a consequence of climate change, could weaken the shells of California mussels and diminish their body mass, with serious implications for coastal ecosystems, UC Davis researchers will report July 15 in the Journal of Experimental Biology.

Worldwide food security could be harmed by changes in ocean chemistry driven by fossil fuel use, according to a new scientific study released last week by scientists at Woods Hole Oceanographic Institution. The study, which ranks nations according to their vulnerability to reduced mollusk harvests due to ocean acidification, was published online by the journalFish and Fisheries on July 7, 2011.
Deaf Fish? An Ocean Acidification Update
On top of destroying coral reefs (the equivalent of wiping out rainforests on land) and killing off shellfish beds, including mussels and oysters, a new report out of the U.K. suggests that the so-called “evil twin” of global warming is responsible for some fish losing their sense of smell.

Pacific-Atlantic route drives up fears of crime and destruction
When it is inaugurated later this month it will signal the realisation of a long-held dream: the completion of a 1,600-mile (2,600km) road cutting through some of South America’s most inhospitable terrain and connecting, for the first time, Brazil‘s Atlantic coast with Peru’s Pacific ports. The road is known as the Interoceanic Highway.
Loss of Large Predators Has Caused Widespread Disruption of Ecosystems
The study looked at research on a wide range of terrestrial, freshwater, and marine ecosystems and concluded that “the loss of apex consumers is arguably humankind’s most pervasive influence on the natural world.”
