Q & A

What is the main focus of Terry Matthews' group at Oak Ridge National Laboratory?

Terry Matthews leads a group focused on understanding the impacts of different energy strategies on biodiversity and ecosystem health within the environmental sciences division.

How are energy and water interconnected according to the discussion?

Energy production requires water for its processes, and conversely, clean water delivery and treatment require energy, highlighting the importance of their relationship.

What is biodiversity, and why is it important?

Biodiversity refers to the variety of life on Earth, and it is essential for ecosystem health, providing clean drinking water, nutritious food, and contributing to disease control.

What traditional methods does the group use to study biodiversity?

The group employs methods such as fishing with rods and nets and electrofishing, which temporarily stuns fish to facilitate sampling.

What role do drones and satellites play in the research?

Drones and satellites are used to monitor larger areas, such as forests and submerged aquatic vegetation, over time to assess environmental changes.

What are some chemical contaminants studied by Matthews, and why are they significant?

Matthews studies nutrients like nitrates and contaminants such as mercury. Mercury is particularly significant because it biomagnifies up the food chain, posing health risks to fish and those who consume them.

What improvements have been observed in water quality and biodiversity over the monitoring period?

The long-term monitoring program has revealed significant improvements in both water quality and biodiversity over the past 35 years.

What innovative strategies is Matthews’ group developing to improve water quality?

The group is working on developing sorbents to absorb mercury and other contaminants from water and is conducting tests in artificial mesocosms.

What role do freshwater mussels play in improving aquatic ecosystems?

Freshwater mussels are filter feeders that improve water quality by removing particles from the water. They are being studied for their potential to restore ecosystems and reduce mercury concentrations.

Why are some species of freshwater mussels considered endangered?

Freshwater mussels are among the most endangered species globally due to their sensitivity to water quality and the ecological roles they play as filter feeders.
