Short lifespan species are more extinction-prone because:
“They cannot sustain population declines” for short lifespan species are more extinction-prone because. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. The mechanism should be evaluated across both local and global scales. Local disappearance can be reversed by recolonization, whereas global extinction is irreversible and requires the loss of every surviving population. The remaining alternatives—“They reproduce excessively”, “They overpopulate rapidly”, “They are r-strategists”—refer to different
