Recording hundreds of thousands of individual uplinks from satellite transmitters fitted on penguins, albatrosses, sea lions, and other marine animals, conservation scientists have released the first-ever atlas of the Patagonian Sea -- a globally important but poorly understood South American marine ecosystem.
Recent theories suggesting that half of fishes' food comes from from land-based ecosystems may not hold water. Experiments show that algae, not land-based matter, is needed to build healthy and fertile aquatic organisms.
The kelp forests off southern California are considered to be some of the most diverse and productive ecosystems on the planet, yet a new study indicates that today's kelp beds are less extensive and lush than those in the recent past.
Coral reefs live in some of the most nutrient deficient waters on the planet, so how do they survive? Marine biologists have discovered that certain sponges could be the key to reef survival. They recycle dissolved organic carbon that is unavailable to other reef residents.
With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life. Researchers have now unraveled the evolutionary relationships among the various species of box jellyfish, thereby providing insight into the evolution of their toxicity.
