The fact that there are more species of beetles in Florida than there are in Canada supports the concept of ______________?
A) Latitudinal gradients.
B) Altitudinal gradients.
C) Community succession.
D) Niche breadth.

Question

Quizplus · Accepted Answer

The concept of latitudinal gradients suggests that biodiversity is greater in tropical regions, closer to the equator, due to a combination of factors such as higher temperature and rainfall. Florida is located at a lower latitude than Canada, so the fact that there are more species of beetles in Florida than in Canada supports this concept. Altitudinal gradients refer to changes in biodiversity with increasing altitude. Community succession refers to the process by which a community transitions from one stage to another over time. Niche breadth refers to the range of environmental conditions and resources that a species can tolerate and utilize. None of these concepts explain why Florida has more beetle species than Canada.
