Variation in heat shock protein 40 kDa relates to divergence in thermotolerance among cryptic rotifer species

open access: yesScientific Reports, 2022
Genetic divergence and the frequency of hybridization are central for defining species delimitations, especially among cryptic species where morphological differences are merely absent.

Cryptic Species Diversity and Phylogenetic Relationship in the Rust Genus Chrysomyxa from China

open access: yesJournal of Fungi, 2022
Chrysomyxa rusts are fungal pathogens widely distributed in the Northern hemisphere, causing spruce needle and cone rust diseases, and they are responsible for significant economic losses in China.

Dispersal and gene flow in free-living marine nematodes [PDF]

open access: yes, 2013
Dispersal and gene flow determine connectivity among populations, and can be studied through population genetics and phylogeography. We here review the results of such a framework for free-living marine nematodes.

Cryptic species composition and genetic diversity within Bemisia tabaci complex in soybean in India revealed by mtCOI DNA sequence

open access: yesJournal of Integrative Agriculture, 2015
Bemisia tabaci is a cryptic species complex, causing significant loss on many agriculturally important crops worldwide. Knowledge on species composition and diversity within B.

Cryptic diversity of the subfamily Calaphidinae (Hemiptera: Aphididae) revealed by comprehensive DNA barcoding. [PDF]

open access: yesPLoS ONE, 2017
Aphids are a species rich group comprising many important pests. However, species identification can be very difficult for aphids due to their morphological ambiguity. DNA barcoding has been widely adopted for rapid and reliable species identification as

Experimental hybridization and reproductive isolation between two sympatric species of tephritid fruit flies in the Anastrepha fraterculus species group [PDF]

open access: yes, 2017
Among tephritid fruit flies, hybridzation has been found to produce local adaptationand speciation, and in the case of pest species, induce behavioral and ecological alterations that can adversely impact efficient pest management. The fraterculus species

Go to the city: Urban invasions of four pipistrelle bat species in eastern Slovakia [PDF]

open access: yes, 2019
Until now, late summer or autumn invasions into inhabited building have been regarded as phenomenon typical for the common pipistrelle, pipistrellus pipistrellus, exclusively.

Cryptic species in Gemmuloborsonia (Gastropoda: Conoidea) [PDF]

open access: yesJournal of Molluscan Studies, 2009
During a broad molecular taxonomic and phylogenetic survey of the gastropod superfamily Conoidea, 80 specimens of several species of the genus Gemmuloborsonia were sequenced for the cytochrome c oxidase subunit I gene. The genus, originally established for fossil species from the Plio-Pleistocene of the Philippines, now includes living species from ...

Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. [PDF]

open access: yesPLoS ONE, 2016
Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic ...

Evolutionarily stable defence and signalling of that defence [PDF]

open access: yes, 2006
We examine the evolution and maintenance of defence and conspicuousness in prey species using a game theoretic model. In contrast to previous works, predators can raise as well as lower their attack probabilities as a consequence of encountering ...
