Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role

Coexistence of cryptic species
Ecology Letters, 2004AbstractRecent discovery of cryptic species in fig‐pollinating wasps creates a puzzle for the ecological competition theory: how do two or more apparently identical species coexist? Conventional theory predicts that they should not. Chesson (Trends Ecol.

Cryptic species as a window on diversity and conservation
Trends in Ecology & Evolution, 2007The taxonomic challenge posed by cryptic species (two or more distinct species classified as a single species) has been recognized for nearly 300 years, but the advent of relatively inexpensive and rapid DNA sequencing has given biologists a new tool for detecting and differentiating morphologically similar species.

Treatment of Infections by Cryptic Aspergillus Species
Mycopathologia, 2014The best treatment for patients with invasive aspergillosis caused by cryptic Aspergillus species remains uncertain, mainly due to the limited clinical data that have been published so far. In face of this limitation, patients should be treated with standard first-line therapy for invasive aspergillosis, with therapy being modified according to in ...

Cryptic species inStachybotrys chartarum
Mycologia, 2002Stachybotrys chartarum has received much attention as a possible cause of sick-building syndrome. Because morphological species recognition in fungi can hide diversity, we applied a phylogenetic approach to search for cryptic species. We examined 23 isolates from the San Francisco Bay Area, and another seven from around the US.

Cryptic species in the Terfezia boudieri complex
Antonie van Leeuwenhoek, 2009Phylogenetic analyses have corroborated the discovery of three internal transcribed spacer (ITS) Types in Terfezia boudieri isolates in the course of earlier studies and have emphasized the divergence of Type 2 from Types 1 and 3. The application of molecular and physiological tools described below, revealed the existence of cryptic species within T ...

Cryptic Species in the Puccinia monoica Complex
Mycologia, 1998The Puccinia monoica complex is an enig- matic group of rust fungi. They are flower mimics, and they greatly reduce host reproduction and sur- vival. These fungi are relatively common, attacking approximately 960 species in 11 genera of crucifers as well as at least five genera of grasses.

We emphasise the importance of DNA studies for the description of new and cryptic species of “desert truffles”. Terfezia canariensis is described in the claveryi group. T. alsheikhii, T. olbiensis, T. fanfani and five new species are recently proposed: T. extremadurensis, T. eliocrocae, T. pini, T. pseudoleptoderma and T.

INVESTIGATIONS IN CRYPTIC SPECIES
2016Snake species are notoriously difficult to study in the field due to their cryptic natural-histories and secretive behaviors. Difficulties associated with detection present challenges estimating parameters including occupancy and abundance, as well as responses to habitat degradation.

Delimitation of cryptic species inside Claviceps purpurea
Fungal Biology, 2015Claviceps purpurea is an ovarian parasite infecting grasses (Poaceae) including cereals and forage plants. This fungus produces toxic alkaloids and consumption of contaminated grains can cause ergotism in humans and other mammals. Recent molecular genetics studies have indicated that it included three cryptic species (G1, G2, G3).
