Highways allow people to travel between towns and cities, but it also divides ecosystems into smaller pieces. Animals can become separated from lakes they use for food and shelter. For example, tiger salamanders use lakes for these reasons. How could the building of highways affect animals such as the tiger salamander?

• Tiger salamanders could improve lake ecosystems.

• Tiger salamanders may be cut off from important resources.

• Tiger salamander habitats may have less pollution.

• Tiger salamander habitats within ecosystems would become larger.
