An ecologist was observing two species of mouse that lived at different elevations on a mountain. In the lab, she observed that
dolphi86 [110]

The species had the same fundamental niche, but the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.

<h3>Why is the perceived niche considered a subset of the fundamental niche?</h3>

Well, as we know, the perceived niche is smaller than the fundamental niche, in other words it is a specific portion of the fundamental niche, so it is considered a subset of the fundamental niche.

With this information, we can conclude that the species had the same fundamental niche, but that the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.
