“Wei-Assipu-tepui”的意思、由来-开放百科全书

Wei-Assipu-tepui has a maximum elevation of around {{convert|2400|m|ft|sigfig=3}}.^[1] Its summit plateau is highly dissected and generally inclined south-southwest (towards the Brazilian side).^[3] The rocky summit is partially forested, with flowering plants of the genus Bonnetia featuring prominently.^[7] It also hosts a number of carnivorous plants, including Heliamphora glabra, Heliamphora nutans, and the natural hybrid between the two.^[2] The various rock cavities of Wei-Assipu-tepui are home to nesting colonies of white-collared swifts (Streptoprocne zonaris) and oilbirds (Steatornis caripensis).^[3] For the latter species, Wei-Assipu-tepui is the easternmost recorded locality in mainland South America, and the first known nesting site in Brazil.^[3] The mountain's summit supports a greater variety of herpetofauna than the less vegetated plateaus of nearby Roraima-tepui, Kukenán-tepui, Yuruaní-tepui, and Ilú-tepui.^[1] Day temperatures of 17 °C have been recorded on the summit plateau, falling to 12 °C overnight, with slightly lower values in the more sheltered caves.^[7]

In the first expedition of its type to Wei-Assipu-tepui, an Italian–Venezuelan team of speleologists explored the mountain's summit plateau in July 2000, surveying four caves and several minor cavities.^[3]^[4] On this expedition were also discovered four previously unknown species of frogs (one of which was later described as Oreophrynella weiassipuensis^[5]), and at least two of harvestmen.^[6]

According to Carreño et al. (2002), the oldest biblio-cartographic reference to the mountain is likely that of Marie Penelope Rose Clementi (wife of Cecil Clementi), circa 1920,^[7] who recounted how its location was determined with a prismatic compass during an English expedition of 1915.^[3]
