Abstract
  • Overview: The population of Southern Resident killer whales has been on the decline for decades, dropping 20% since the mid 1990s. Starvation appears to be a factor in the deaths of many of these whales. The Southern Resident killer whales survive mainly on a diet of Chinook salmon, which is another species in decline due to a variety of human impacts. In this lesson, students explore how the selective feeding practices of Southern Resident killer whales contribute to their declining numbers.
  • Learning Goals: Students will learn the following: • Southern Resident killer whale (SRKW) and Chinook salmon populations are in significant decline due to the impacts of human activities on marine ecosystems. • Environmental changes affect food web dynamics. • SRKWs and juvenile Chinook salmon are selective feeders. • Effective species recovery plans for SRKW and Chinook salmon include an understanding of ecosystem relationships.
