The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels. Sea otters also indirectly reduce atmospheric carbon dioxide levels by improving kelp forests, which absorb and store carbon dioxide, a major greenhouse gas. The greater the number of CO molecules, the higher the percentage of hemoglobin turns into COHb (%COHb) and the greater the harm: We suffocate when the oxygen levels in our tissues drop too low.

Wilmers, Estes, a professor of ecology and evolutionary biology, and their co-authors, combined 40 years of data on otters and kelp bloom from Vancouver Island to the western edge of Alaska's Aleutian Islands. Unlike in an open-water coastal environment, internal wave energy through a kelp forest is diminished by the kelp, reducing the turbulence that helps mix water from the surface to the seafloor. It would be difficult to recreate the exact conditions of the chemical release elsewhere. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or run cars, and cut down trees, the amount of carbon dioxide in the air is increased. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); A new study by two UC Santa Cruz researchers suggest that a thriving sea otter population that keeps sea urchins in check will in turn allow kelp forests to prosper.

Answer (1 of 3): Abiotic factors in an environment include such items as sunlight, temperature, wind patterns, and precipitation, could affect sea otters or any other animal if exposed to them adversely. When they are in an environment with a lot of carbon dioxide, they will breathe more quickly to get rid of the excess. 5) No moving parts. Urchins eat kelp. CO 2 levels in deep water are about 10% higher than in surface waters. While much is known about the direct effect that temperature can have on aquatic communities, less is known about its indirect effect via the temperature dependence of viscosity and temperature-dependent trophic interactions.

As a result, a forest with a high biomass of kelp ensures that the surrounding waters remain well oxygenated. Phone: 020 7427 6072. You recommend he take an antihistamine. Dissolved oxygen (DO) refers to the concentration of oxygen gas incorporated in water. 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. The reading passage tries to give some reasons to show that the number of sea otters, a small mammal living along the western coast of North America, has significantly declined because of the environmental pollution.

Purpose: This study evaluated the DNA double strand breaks (DSBs) induced by indirect actions and its misrepairs to estimate the relative biological effectiveness (RBE) of proton beams.Materials and methods: From experimental data, DSB induction was evaluated in cells irradiated by 62 MeV proton beams in the presence of dimethylsulphoxide (DMSO) and under hypoxic conditions. Studies have shown that kelp forests enhance the underwater environment, providing a suitable habitat for fishes. For example, beavers and otters may show few effects under good conditions, but during times of stress (e.g., extended severe weather), contaminants could have a more pronounced impact. beacon hill estate leesburg, va. indirect effect of temperature on sea otterspapyrus sympathy card. 2010 The Authors.
