Through the use of acoustic data deeper than 200 m and considering the open-ocean areas between 40° N and 40° S with bottom depth deeper than 1,000 m and trophic levels 3–3.5 this analysis ...

Biodiversity was booming in the early Cretaceous Period, and not just among dinosaurs. The oceans also teemed with life, ...

Individual leopard seals specialize in specific prey types despite being generalist species, reshaping ecosystem dynamics.

NASA’s satellites have been photographing the open ocean. Three oceanographers from Duke used this data to examine how the ...

In fact, sea urchins replaced fish at the lower trophic levels, and sea urchins are a direct prey source for some mid-trophic level fish, like wrasse and triggerfish.

Just in time for summer, the megalodon—the ancient, city bus-sized shark known as the “Megatooth”—has reared its ravenous snout. While the oceans are now safe from the Megatooth, which went extinct an ...

These metals, such as mercury, can easily accumulate in aquatic organisms and transfer to higher trophic levels. Human activities have significantly increased mercury emissions in the environment.

Same with lead if concentrations go beyond a certain value. We really don’t understand how well lead is taken up by organisms and if it is bioaccumulative in nature with every passing trophic level.
