Incorporating the speciation process into species delimitation. [PDF]
PLoS Computational Biology, 2021 The "multispecies" coalescent (MSC) model that underlies many genomic species-delimitation approaches is problematic because it does not distinguish between genetic structure associated with species versus that of populations within species. Consequently,

Species delimitation in the cyanolichen genus Rostania [PDF]
BMC Evolutionary Biology, 2020 Background In this study, we investigate species limits in the cyanobacterial lichen genus Rostania (Collemataceae, Peltigerales, Lecanoromycetes). Four molecular markers (mtSSU rDNA, β-tubulin, MCM7, RPB2) were sequenced and analysed with two coalescent-

Species delimitation and global biosecurity [PDF]
Evolutionary Bioinformatics, 2011 Species delimitation directly impacts on global biosecurity. It is a critical element in the decisions made by national governments in regard to the flow of trade and to the biosecurity measures imposed to protect countries from the threat of invasive ...

Species delimitation and geography [PDF]
Molecular Ecology Resources, 2020 Despite the importance of the geographical arrangement of populations for the inference of species boundaries, only a few approaches that integrate spatial information into species delimitation have thus far been developed.

Gene flow and species delimitation
Trends in Ecology & Evolution, 2009 International audienceA defining feature of species is that their constituting populations are connected by gene flow. However, interspecific gene flow (introgression) can affect species integrity.

Piikun: an information theoretic toolkit for analysis and visualization of species delimitation metric space [PDF]
BMC BioinformaticsBackground Existing software for comparison of species delimitation models do not provide a (true) metric or distance functions between species delimitation models, nor a way to compare these models in terms of relative clustering differences along a ...

Species delimitation in Amblyosyllis (Annelida, Syllidae).
PLoS ONE, 2019 Amblyosyllis is a worldwide distributed group of annelids mainly found in coastal environments. It is well known among the polychaete specialists mostly because of its notable beauty, showing bright colourful patterns and outstanding long and coiled ...
