A school of fish swims alongside sharks. Predator–prey relationships are shifting as declines in large top predators and increases in smaller, more generalist species are reshaping fish food webs ...

Some ancient fish in the Caribbean may have lost their lunch. Modern food chains on coral reefs off the coasts of the Dominican Republic and Panama are roughly 60 to 70 percent shorter than they were ...

Babies and very young sauropods—the long-necked, long-tailed plant-eaters that in adulthood were the largest animals to have ever walked on land—were a key food sustaining predators in the Late ...

BUFFALO, N.Y. — When University at Buffalo chemists analyzed samples of water, fish, and bird eggs, they weren’t surprised to find plenty of per- and polyfluoroalkyl substances (PFAS). After all, ...

Mining the seafloor for valuable metals could send dangerous ripples through ocean food webs. Tiny floating plankton, the base of the food web, can accidentally ingest particles of sediment kicked up ...

The ocean is losing its greenness, a new study has found: Global chlorophyll concentration, a proxy for phytoplankton biomass, declined over the past two decades, especially in coastal areas.

Microbes near the surface of the Southern Ocean sustain the polar food chain — impacting the nutrient flow from the surface to the depths where other microbial communities thrive in the dark. National ...

SEATTLE (AP) — For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic ...

For decades, scientists believed Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic bacterium, which ...

Sampling snapper on coral reefs to assess their role in complex reef food web dynamics. “When you dive on these beautiful Red Sea reefs, one of the first things that you’ll notice is these snapper ...

Scientists are gaining new insights into how plankton supports life on Earth — just as climate change is changing everything. Scientists are gaining new insights into how plankton supports life on ...
