The storage effect refers to the phenomenon in ecology where the survival and growth of a species is enhanced by the ability to store resources for future use. This allows the species to thrive in environments with fluctuating resource availability, as they are able to utilize stored resources during times of scarcity. This effect is particularly important for long-lived species, as it allows them to maintain a competitive advantage over shorter-lived species. The storage effect is a crucial adaptation that allows species to persist and thrive in ever-changing environments.
