Please read the text below and respond to the questions that follow. Expansion of Species
Natural environmental changes such droughts can lead to the expansion of a species' range. For example, long-lasting drought can change an ecosystem to make it more suitable for plants adapted to dry conditions. These plants could expand into the ecosystem and outcompete plants that are less well-adapted to dry conditions. Expansion
The barred owl historically lived in the eastern United States and the Great Plains was a barrier to the westward expansion of many species including the barred owl. Over time, the climate got warmer and the settlers planted more trees, so the ecosystem of these plains has changed. These environmental changes are causes for the barred owl range expansion to the Western regions of the United States.
Questions
1. From the cited examples, what can you infer about the "artificial factors"
2. What was the most significant barrier to the expansion of species from east to west?
