Why does the limited range of the Sphaerodactylus parthenopion place it at high endemism risk?
Answer
Its restriction to a few islands makes it highly vulnerable to habitat disturbance and invasive species
High endemism risk occurs when a species is confined to a very small geographic area. Because this gecko is found only on a handful of islands and cays, it lacks the broader range that might buffer other species against localized threats. Consequently, factors like coastal development, the introduction of invasive predators like rats or predatory ants, and climate-induced changes in humidity or storm severity pose existential threats to the entire species, as there are no other populations to repopulate these areas if local groups are decimated.
