Question

The white dove and the smaller spotted grey dove are closely related species that nest on high altitude granile cliffs Like the while dove, the spotted grey dove builds nests on the cliffs Building nests on the cliffs protects their eggs and young from generalist predators such as rats, foxes and snakes However, unlike white doves, the spotted grey dove spends the winter in the low lands where the temperatures are warmer. The spotted grey dove cannot survive the cold winters at altitude because of their smaller body size From these observations, we can conclude that The white dove and the spotted grey dove are actually two populations of the same species The distributions of both dove species are limited by the same biotic factors but their distributions are limited by different abiotic factors The white dove is more at risk of extinction due to competition for biotic resources with humans The distributions of the two dove species are limited by some shared and some different biotic factors. The distributions or born dove species are limited by the same abiotic factors but their distributions are limited by different biotic factors.

Explanation / Answer

Answer A) the white dove and the spotted grey dove are actually two populations of the same species

Spotted grey dove - Spilopelia senegalensis

White dove - Streptopelia risoria

Spilopelia is a genus of doves, small in number, that are closely related to Streptopelia. The two species are distinguished by the differences in their behaviour and morphology.
