Wild Maine Series: Understanding Marine Birds and Ecosystems

The video is part of the Wild Maine series and features a presentation by Dr. Allie McKnight on the importance of seabirds in understanding ocean health. It covers the complexity of marine ecosystems, the challenges in studying them, and how seabirds serve as indicators of ocean health. The presentation also discusses seabird adaptations, their role in ecosystem management, and concludes with a Q&A session addressing audience questions about marine systems and seabirds.

What is the primary mission of the Center for Wildlife Studies?

• To conduct wildlife research exclusively in Maine

• To provide accessible environmental education and promote global wildlife conservation

• To develop new technologies for wildlife tracking

• To focus on the conservation of marine mammals

What percentage of the Earth's surface is covered by oceans?

• 71%

• 60%

• 50%

• 80%

Which of the following is NOT a factor used to delineate marine ecosystems?

• Currents

• Salinity

• Temperature

• Vegetation form

What is a significant physiological adaptation of birds for flight?

• Slow metabolism

• High-pressure circulatory system

• Inability to regulate body temperature

• Lack of color vision

Why are seabirds considered top predators in ocean food webs?

• They have no natural predators in the ocean

• They only eat plants

• They are the largest animals in the ocean

• They live exclusively on land

How can seabirds help predict changes in fish populations?

• Through their vocalizations

• Through their diet data indicating fish population trends

• By altering their nesting sites

• By changing their migration patterns

What was a significant finding from the study of seabird populations from 1950 to 2010?

• A 70% increase in seabird populations

• A 70% decline in seabird populations

• No significant change in seabird populations

• Seabird populations doubled

What is one application of bird-borne sensors in oceanographic research?

• Measuring the depth of the ocean floor

• Tracking the migration of fish

• Validating satellite data on sea surface temperature

• Mapping the distribution of coral reefs

How do seabirds contribute to fisheries management?

• By providing data on fish abundance through their diets

• By directly catching fish for human consumption

• By migrating to areas with fewer fish

• By preventing overfishing through their presence

What is a potential benefit of using seabirds in oceanographic research?

• They can communicate with marine mammals

• They can predict weather patterns

• They provide data from areas difficult to access by humans

• They can replace all traditional research vessels
