Environmental Science and Salamander Adaptations

The SA Show features Mike Potts, an engineer working on environmental restoration in Montana. Mike discusses his background in ecohydrology and his transition to engineering to solve environmental problems. He explains groundwater modeling and the importance of monitoring water quality. The conversation shifts to Superfund sites, particularly in Montana, and the challenges of cleaning up mining contamination. Mike also talks about stream restoration projects and the integration of public access through parks. The show concludes with a segment on the tiger salamander, highlighting its unique adaptive traits.

What is the primary focus of Mike Potts' work?

• Building new dams

• Developing new mining techniques

• Restoring natural habitats and cleaning up environmental messes

• Designing urban landscapes

What is the relationship between surface water and groundwater?

• Groundwater flows into the ocean directly

• Surface water is an expression of groundwater

• Surface water is always cleaner than groundwater

• They are completely independent

What is a Superfund site?

• A government-funded program to clean up contaminated areas

• A wildlife conservation area

• A recreational park

• A site for new construction projects

Why is it important to manage the water in the Butte mining pit?

• To prevent it from overflowing into the ocean

• To prevent contaminated water from entering the groundwater system

• To ensure it remains a tourist attraction

• To use it for agricultural purposes

What was the role of the dam in Milltown?

• To prevent contamination from spreading downstream

• To generate electricity

• To create a recreational lake

• To provide water for irrigation

What is unique about the life cycle of the tiger salamander?

• It migrates long distances annually

• It can choose to remain aquatic or become terrestrial

• It only lives in saltwater

• It hibernates for most of the year

How do tiger salamanders adapt to environmental changes?

• By migrating to different regions

• By altering their developmental path

• By becoming nocturnal

• By changing their diet

What happens to tiger salamander larvae when they compete for resources?

• They migrate to new habitats

• They develop larger heads and mouths

• They form social groups

• They become herbivores

What is the average length of a mature tiger salamander?

• 14-16 inches

• 2-4 inches

• 6-8 inches

• 10-12 inches

What is the significance of the Greenway component in stream restoration?

• It focuses on building new roads

• It involves creating parks and trails for public access

• It is a method for increasing fish populations

• It is a technique for planting trees
