Description:Antarctic krill are a keystone species in the Southern Ocean
ecosystem and are fed upon by several predators, including
whales, penguins, seals and seabirds. As climate change causes
temperatures to rise, krill populations are migrating south and
becoming less prominent at the Antarctic Peninsula. Can the
response of this one species impact an entire ecosystem? Scientists
at Oregon State University are studying how changes in the
environment, such as temperature rise, impact the survival and
reproduction of Antarctic krill. This lesson will introduce middle
school students to Antarctic ecosystems and the critical role krill
play in the environment. We will look at how krill populations have
changed over time in relation to rising temperatures, and dive into
the causes of global temperature rise, its effects on polar
ecosystems, and what solutions can be implemented to lower our
carbon emissions.
