Ocean islands fuel productivity and carbon sequestration through natural iron fertilization
An experiment to study the effects of naturally deposited iron in the Southern Ocean has filled in a key piece of the puzzle surrounding iron's role in locking atmospheric carbon dioxide (CO2) in the ocean. The research, conducted by an international team led by Raymond Pollard of the National Oce...
Study of islands reveals surprising extinction results
(Santa Barbara, Calif.) It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands.
Their research, published this month in...
Rats on islands disrupt ecosystems from land to sea, researchers find
SANTA CRUZ, CA--Seabird colonies on islands
are highly vulnerable to introduced rats, which find the ground-nesting birds to be easy prey. But the ecological impacts of rats on islands
extend far beyond seabird nesting colonies, according to a new study by researchers at the University of Californ...
First wind turbines on Galapagos Islands will halve diesel imports, reduce risk of future oil spills
In January 2001, the world held its breath when the tanker Jessica, loaded with 150,000 gallons of fuel, struck a reef and began breaking up in the heart of one of the most precious, famous and fragile ecosystems on earth the Galapagos Islands.
At risk were vast numbers of unique species of fl...
