The appetite of the sea otter is a threat to individual abalone who have not hidden themselves in deep rocky crevices, but where sufficient crevice habitat is available, this same appetite brings benefits to abalone populations. www.esajournals.org/doi/abs/10.1890/110176, Journal information: Increases in kelp and seagrass due to sea otters can translate into increased carbon sequestration. Ecol Evol. Nest use dynamics of an undisturbed population of bald eagles. Overall, indirect effects of temperature via changes in viscosity were subtle in comparison to the indirect effect of temperature via trophic interactions. Since then, conservation efforts have allowed the otters to rebound somewhat, but some 2,500 miles (4,000km) of coastline in their historic range is still devoid of the furry mammals. But if those protons leak back over the membrane before being used for work, that energy is lost as heat. Sea otters are creatures steeped in superlatives. By the submission of this blog, there were 1,336 views. They are a keystone species, which means they have a big impact on keeping their ecosystem balanced. "When I think about marine plants that can sequester carbon really well, it's typically the rooted ones," says Hughes. Using data on the rate of kelp growth and its density at sites with and without otters, they found that the presence of sea otters across rocky reef habitat in the study area, covering 51,551 square kilometers (19,900 square miles an area about the same size as Costa Rica), is capable of storing 4.4 to 8.7 million tonnes of carbon compared to if an otter-free condition.
