Species Range Changes in Biome Transitions

Case 1: The biome of a small agricultural community in the western United States changes from grassland to desert. A species of migrating duck, which can carry bird flu, goes locally extinct.

Case 2: The biome in northern Russia changes from tundra to taiga. Timber harvesting in the region becomes possible. Arctic foxes go locally extinct and are replaced by red foxes that commonly carry rabies.

Sort the consequence based on whether it would apply to Case 1, Case 2, or both: species range changes

The consequence of "species range changes" would apply to both Case 1 and Case 2.

• In Case 1, the change from grassland to desert could lead to shifts in the ranges of various species, including the migrating duck and other local fauna and flora.
• In Case 2, the transition from tundra to taiga would also result in changes to the ranges of species, such as the replacement of Arctic foxes with red foxes.

Therefore, "species range changes" is applicable to both cases.
