Which combination correctly describes IDH?
The intermediate disturbance hypothesis proposes a hump-shaped relationship between disturbance intensity or frequency and local diversity. With little disturbance, strong competitors may exclude weaker species and reduce coexistence. Severe or very frequent disturbance removes many organisms, especially slow-growing or disturbance-sensitive taxa, leaving only a limited tolerant set. At intermediate levels, competitive exclusion is interrupted without eliminating most populations, allowing colonizers, tolerant species, and superior competitors to coexist. The hypothesis is context dependent ra
