What profound ecological implication arises from *Potamotrygon leopoldi*'s endemism to the Xingu River?
Answer
Hydroelectric dam construction poses a direct and immediate threat to the entire species population
The high degree of endemism, meaning the Xingu River Ray is naturally found nowhere else on Earth, directly translates into severe conservation vulnerability. Because these freshwater rays are poor dispersers across large, high-gradient barriers, the entire population is intrinsically tied to the specific hydrology of the Xingu drainage basin. Consequently, major alterations to this habitat, such as the construction of large hydroelectric dams that impede movement upstream or downstream, present an existential threat to the species because no secondary refuge population exists elsewhere to bolster survival rates or facilitate recovery.
