1. One factor that leads to a decline in biodiversity is the introduction of non-native species. However, most species that are introduced to an area do not become established. What are some characteristics of species that might make them more likely to thrive in a new habitat?

2. Several species of large rats arrived to Hawaii as stowaways on ships. These rats live in a varietyof habitats and eat a variety of foods, both plants and animals. Speculate about how these introduced rats could directly and indirectly affect native bird species.

3. Researchers hypothesize that several factors may affect the extent of predation by rats on birds.These factors include bird size, nesting site, and the amount of time young spend in the nest (duration of egg incubation and nestling period). Formulate a hypothesis about how one of these factors might affect predation.
