Definition of "tepui"

Once a population becomes adapted to the tepui summit environment, it is more likely to colonize other areas with similar environmental conditions, so it would need to disperse between tepui summits to expand its geographical range.

One of the most dominant landscape features in the Gran Sabana is a flight of planation surfaces rising from modern sea level to the summits of the high tepui (Briceño and Schubert 1990).

On the other hand, because birds and small mammals are relatively rare on tepuis, the principal potential vertebrate food for snakes on tepui summits would seem to be frogs, most of which are nocturnal (e.g., species of Tepuihyla, Stefania, Hypsiboas, Pristimantis, Anomaloglossus, and Otophryne).
