As a result of the change in the migratory pattern, the two groups of blackcaps (those that migrate to England vs those that migrate to Spain) have different mating seasons. Blackcaps that migrate to England have an earlier mating season. Scientists believe that this difference may result to two different species of birds. This shows:

A)

the effect of symbiosis

B)

the effects of local evolution or migration on an ecosystem

C)

the difference between biotic and abiotic factors in an ecosystem

D)

how migratory patterns change in response to alterations in an ecosystem
