To do that, they needed to compare areas with lots of otters to spots with just a few or none. We manipulated the temperature (5-20 C) and the viscosity (equivalent to 5-20 C) of water in laboratory-based . Without sea otters, sea urchins and other herbivorous invertebrates are left unchecked to graze through swathes of giant kelp forests, creating barren stretches of coastal habitat behind them that once served as nurseries for fish, seals and hordes of other sea life. Although they can live in both salt and fresh water, they prefer to live in areas with a high concentration of fish. Kelp has an incredibly fast growth rate (up to two feet per day) and exports a large portion of its biomass out into the deep sea, allowing kelp to permanently remove carbon dioxide from the atmosphere.

The sea otter is the largest of the Mustelidae, being rivaled only by the giant Amazonian otter (Pteronura brasiliensis), itself threatened with extinction. As the smallest and one of the most recently evolved marine mammals, sea otters face physiological challenges rarely encountered by larger, more derived aquatic species. On Sea Otters, We Need to See the Big Picture, a new study published in the journal Frontiers in Ecology and the Environment. Over time, kelp forests grow to absorb atmospheric CO2 and release oxygen into the atmosphere; the process is known as photosynthesis. sharing sensitive information, make sure youre on a federal First, ethical issue that consists of the species being seen as vital, "Polar Bears, Ringed Seals, and the Complex Consequences of Climate Change" is an article written by Mary Bates who earned her PhD studying Bat echolocation.
