Threats to Freshwater Mussels and the Consequences for Ecosystems - Science Nation

The video discusses the critical role of freshwater mussels in river ecosystems, highlighting their ecological importance and the threats they face, such as habitat fragmentation and human water needs. Zoologist Caryn Vaughn's research focuses on mussels' reproduction, their role in water filtration, and the economic value of their ecological services. The video emphasizes the importance of biodiversity in mussel beds for ecosystem health and the need for conservation efforts to protect these species.

What is a major threat to freshwater mussels today?

• Climate change

• Pollution from agriculture

• Habitat fragmentation

• Overfishing

How do freshwater mussels disperse their larvae?

• By burying them in the riverbed

• By sticking them onto fish

• By releasing them into the water

• By attaching them to birds

What is one of the roles of mussels in their ecosystem?

• Filtering water

• Creating habitats for birds

• Producing oxygen

• Providing food for large fish

Why is species diversity important in mussel beds?

• It increases the water temperature

• It enhances the mussels' condition

• It reduces the need for fish

• It prevents algae growth

What additional benefit do mussel shells provide in aquatic environments?

• They shelter insect larvae

• They reduce water acidity

• They attract more fish

• They increase water flow
