Multiple choice

Which of the following is a major challenge facing biogeographic research?

  1. Climate change

  2. Habitat loss

  3. Invasive species

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above are major challenges facing biogeographic research. Climate change is causing the distribution of organisms to shift, and this is leading to changes in the composition of ecological communities. Habitat loss is reducing the amount of habitat available for organisms, and this is leading to declines in population sizes. Invasive species are being introduced to new areas, and this is leading to competition with native species and changes in the composition of ecological communities.
