How does land that gets broken up contribute to loss of species diversity?

Answer 1

When land gets broken up, such as through continental drift, animals are separated. Each section of land initially contains a smaller population of animals. There are fewer mating choices, which decreases species diversity.

Answer 2

Land that is broken up contributes to the loss of species diversity by reducing the ability of some species to survive. Also, smaller areas of land cannot support as many species, resulting in a loss of diversity.

Answer 3

You get a genetic bottleneck affect causing inbreeding which usually hits the immune system the hardest making the animals much more susceptible to death from disease. Also by removing a large percentage of the gene pool you remove some traits which are valuable to the evolution of the species causing a decline in the adaptations of the species.

Answer 4

When land is broken up into smaller fragments, it can isolate populations of species and reduce their ability to migrate, find mates, and access resources. This can lead to inbreeding, loss of genetic diversity, and higher extinction risk for certain species. Fragmentation also disrupts ecosystems and can result in the loss of habitat and disruption of ecological processes, further contributing to loss of species diversity.
