THE ROLE OF APEX PREDATORS IN A SUSTAINABLE ECOSYSTEM


Food web interactions and contaminant transfer determine the flow of energy in the ocean and ultimately drive population dynamics, community structure, and most ecosystem processes. However, unpredictable and highly variable, changing environments can also affect how ecosystems interact.

Top predators like marine mammals, pelagic fishes, and seabirds are considered key components of marine communities and ecosystem functioning. Determining the role of all members of a food web provides insights into ecosystem stressors and potential adaptations to disruptions and changes throughout the marine ecosystem.

Seminar Takeaways:

  • Increasing environmental stressors impact the entire marine ecosystem
  • Complexity and diversity are the keys to survival
  • Environmental changes reflected in apex predators
