On the identity of broad-shelled mussels (Mollusca, Bivalvia, Mytilus) from the Dutch delta region [PDF]
, 2011 Late Quaternary (Eemian) deposits of the Netherlands contain shells that resemble those of living Mytilus galloprovincialis. Similar broad-shelled mytilids also occur in estuaries of the southwestern Netherlands together with slender individuals typical ...

The ascomycete Verticillium longisporum is a hybrid and a plant pathogen with an expanded host range. [PDF]
PLoS ONE, 2011 Hybridization plays a central role in plant evolution, but its overall importance in fungi is unknown. New plant pathogens are thought to arise by hybridization between formerly separated fungal species.

Molecular Plant-Microbe Interactions, 2021 The emergence of new fungal pathogens through hybridization represents a serious challenge for agriculture. Hybridization between the wheat mildew (Blumeria graminis f. sp. tritici) and rye mildew (B. graminis f. sp.

Cryptic and extensive hybridization between ancient lineages of American crows [PDF]
Molecular Ecology, 2018 Abstract Most species and therefore most hybrid zones have historically been defined using phenotypic characters. However, both speciation and hybridization can occur with negligible morphological differentiation.

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

DNA hybridization evidence for the principal lineages of hummingbirds (Aves:Trochilidae) [PDF]
Molecular Biology and Evolution, 1997 The spectacular evolutionary radiation of hummingbirds (Trochilidae) has served as a model system for many biological studies. To begin to provide a historical context for these investigations, we generated a complete matrix of DNA hybridization distances among 26 hummingbirds and an outgroup swift (Chaetura pelagica) to determine the principal ...

Allele segregation analysis of F1 hybrids between independent Brassica allohexaploid lineages [PDF]
Chromosoma, 2021 Abstract In the Brassica genus, we find both diploid species (one genome) and allotetraploid species (two different genomes) but no naturally occurring hexaploid species (three different genomes, AABBCC).

Frontiers in Genetics, 2019 It has been shown that reciprocal cross allodiploid lineage with sub-genomes derived from the cross of Megalobrama amblycephala (BSB) × Culter alburnus (TC) generates the variations in phenotypes and genotypes, but it is still a challenge to deeply mine ...

Biological compatibility between two temperate lineages of brown dog ticks, Rhipicephalus sanguineus (sensu lato) [PDF]
, 2018 Background: The brown dog tick Rhipicephalus sanguineus (sensu stricto) is reputed to be the most widespread tick of domestic dogs worldwide and has also been implicated in the transmission of many pathogens to dogs and humans.

Natural hybridization between divergent lineages in a selfing hermaphroditic fish [PDF]
Biology Letters, 2018 By definition, mating between individuals is infrequent in highly selfing organisms, and so too, therefore, hybridization should be rare between genetically divergent lineages in predominantly self-fertilizing species. Notwithstanding these expectations, here we report a remarkable case of natural hybridization between highly diverged phylogeographic ...
