A new species of Heliamphora, or a new Oreophrynella toad species, or a new orchid found on a tepui summit that had not been thoroughly surveyed — these findings appear in the systematic biology literature with enough regularity to make clear that the biological inventory of the tepui highlands is not complete.

International collaborations between scientists from Venezuela, Guyana, Brazil, and research institutions in Europe and North America are now the norm for tepui research, reflecting both the multinational character of the region and the practical reality that no single institution has the resources to conduct comprehensive research across the entire tepui highland.

The Peculiar Black Color

One of the most visually distinctive features of the Roraima summit — and one that photographs rarely capture adequately — is the deep black color of much of the rock surface.

The blackness is not the natural color of the sandstone itself, which tends toward tan, cream, and brownish-red shades when freshly exposed.
