Well-known cultured HNF are not usually found in clone libraries. That indicates that novel taxa are dominant in the aquatic environments.

After combining sequences retrieved from different environmental studies new clusters are constituted. This is what we have defined as Emerging Diversity.

This and other related studies indicates that most of the HNF are not cultured. Is extremely important to increase the culturing effort and assume that an strong culturing bias is affecting the study of HNF.

Emerging diversity will probably appear in all protists lineages. A deep analysis of molecular surveys is needed to improve protists phylogeny.
