Define the Fundamental Niche.
Define the Fundamental Niche.
The fundamental niche is the full range of environmental conditions an organism can possibly occupy and use, related to climate and thermal performance curves.
Why do species distributions (ranges) generally vary predictably across climate gradients?
Why do species distributions (ranges) generally vary predictably across climate gradients?
Species distributions vary predictably across climate gradients because species have different niches regarding environmental conditions, and they occur in the environments where they perform best.
