The existence of plant and animal endemisms, particularly in biomes in the middle and high mountains were basic indicators for recognizing the singular nature of the Sierra Nevada de Santa Marta and establishing the status as of Biosphere Reserve in this biogeographic unit.

This latter plant with only a single species endemic to the páramo and another species in the high mountains of central Ecuador, represents a biogeographic curiosity.

If the arctic host populations become fragmented due to the northward expansion of southern biogeographic elements, extinction of parasites in small host populations and/or cryptic speciation (isolation events seen in parasites, often only by using molecular methods, that are not evident in host populations) in refugia are likely to follow.
