A hotter ocean is a hungrier ocean—at least as far as fish predators are concerned. In a new field study published online June 9 in Science, Smithsonian scientists discovered predator impacts in the ...

Marine biologists tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale. Night and day, oil tankers, yachts and cargo ships stacked ...
