Cryptic and New Species

2013
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.

Cryptic Species in the Puccinia monoica Complex

Mycologia, 1998
The 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.

Antifungal Susceptibility Profile of Cryptic Species of Aspergillus

Mycopathologia, 2014
The use of molecular tools has led to the description of new cryptic species among different Aspergillus species complexes. Their frequency in the clinical setting has been reported to be between 10 and 15%. The susceptibility to azoles and amphotericin B of many of these species is low, and some of them, such as Aspergillus calidoustus or Aspergillus ...

INVESTIGATIONS IN CRYPTIC SPECIES

2016
Snake 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, 2015
Claviceps 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).

Biofluorescence as a survey tool for cryptic marine species

Conservation Biology, 2018
Abstract As ecosystems come under increasing anthropogenic pressure, rare species face the highest risk of extinction. Paradoxically, data necessary to evaluate the conservation status of rare species are often lacking because of the challenges of detecting species with low abundance.

Metapopulation Dynamics of Species with Cryptic Life Stages

The American Naturalist, 2013
Quantifying metapopulation dynamics is a challenging task. Difficulties particularly arise in species that possess unobservable resistance forms that bias the estimation of colonization and persistence rates. Here, we develop a general multistate occupancy model that allows estimation of species persistence for both normal and resistant forms, even ...

Cryptic species in the fern Ceratopteris thalictroides (Parkeriaceae). III. Referential diagnostic characters of three cryptic species

Journal of Plant Research, 2008
Three cryptic species of Ceratopteris thalictroides, named the south type, the north type and the third type, were examined for their morphological characteristics, using sporophytes cultivated under common conditions. The discriminant analysis for leaf characters followed by one-way layout ANOVA or Kruskal-Wallis test for selected combinations of ...

Multi-Resistant Aspergillosis due to Cryptic Species

Mycopathologia, 2014
Reports of cryptic species causing aspergillosis in humans are increasing in the literature. Cryptic species are defined as those which are morphologically indistinguishable, although their identifications can be confirmed using molecular or other techniques which continue to become more widely available in the clinical setting.

Cryptic species of insect disease vectors and their importance

Endeavour, 1980
Abstract The control of insect vectors of disease is a very important public health measure, but the need is increasingly being recognised to distinguish between harmful species and closely related ones which, for one reason or another, are relatively unimportant.
