UC Berkeley, U.S.G.S. Scientists Discover Microscopic Invader Of San Francisco Bay, The First Known Marine Microbe Invader Of U.S. Waters
...Some of the species previously reported as natives might
in fact have been introduced before studies of shallow-water foraminifers became common in the 1950s. Cohen thinks that they could have arrived in the bay as hitch-hikers on ship hulls during the Gold Rush, in shipments of oysters from the Atlantic s...

say, 'Oh, at least they have the whole ocean to live in.' With the discovery that turtles are concentrated within narrow corridors, what we're finding is that this may not be true," Morreale said....
Researchers Develop Model Using Birds As Indicator Of Wetlands Health

be. Kelley has been studying the source of these nutrients in what is called "layer three" of the oceanic crust. Located at a depth of about two and a half miles, this layer consists of rock that was once part of molten magma chambers. Although ...
Researchers Find How Disease-resistant Plants Recognize Bacteria
... his "gene-for-gene" theory was correct and how it might
work. In 1993, Martin was successful in cloning the first disease-resistance gene in crop plants, Pto , which is involved in gene-for-gene disease resistance. But Martin and his colleagues at Purdue struggled to understand the molecular mechanism of...
