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 diversity in a fig wasp community—morphologically differentiated species are sympatric but cryptic species are parapatric [PDF]

open access: yesMolecular Ecology, 2017
AbstractA key debate in ecology centres on the relative importance of niche and neutral processes in determining patterns of community assembly with particular focus on whether ecologically similar species with similar functional traits are able to coexist.

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

Postcopulatory sexual selection [PDF]

open access: yes, 2002
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to ...

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 ...

Mitogenomics reveals high synteny and long evolutionary histories of sympatric cryptic nematode species [PDF]

open access: yes, 2016
Species with seemingly identical morphology but with distinct genetic differences are abundant in the marine environment and frequently co-occur in the same habitat.

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 ...

Trematodes of the Great Barrier Reef, Australia: emerging patterns of diversity and richness in coral reef fishes [PDF]

open access: yes, 2014
The Great Barrier Reef holds the richest array of marine life found anywhere in Australia, including a diverse and fascinating parasite fauna. Members of one group, the trematodes, occur as sexually mature adult worms in almost all Great Barrier Reef ...
