In this article Mary talks about how Climate change is impacting different species at different rates. The effect is that less hemoglobin is available to carry oxygen to the tissues. The carbon dioxide indirect effect on otters refers to the fact that carbon dioxide emissions can lead to ocean acidification, which in turn can negatively impact otters. Comparing kelp density with otters and kelp density without otters, they found that "sea otters have a positive indirect effect on kelp biomass by preying on sea urchins, a kelp grazer." In the winter, when the water is frozen into ice, they create holes so they may rise to the surface to breathe. Coral reefs and seaweed ecosystems are already being harmed as a result of global warming. To prevent themselves from being drift away by tides and currents, they anchor themselves by scraps of kelp around their body. This second prospect has the greatest potential to decrease atmospheric carbon levels, as carbon could remain trapped in plant tissues at the bottom of the sea for decades or centuries. To examine the effect of these challenges on foraging costs and resultant daily energy budgets, we measured the energetics of resting, grooming, diving and foraging for adult, male sea otters.
