Species delimitation and hybridisation history of a hazel species complex.
Annals of Botany, 2021 BACKGROUND AND AIMS Hybridisation increases species adaptation and biodiversity but also obscures species boundaries. In this study, species delimitation and hybridisation history were examined within one Chinese hazel species complex (Corylus chinensis ...

Delimiting species in Basidiomycota: a review [PDF]
Fungal Diversity, 2021 Species delimitation is one of the most fundamental processes in biology. Biodiversity undertakings, for instance, require explicit species concepts and criteria for species delimitation in order to be relevant and translatable. However, a perfect species concept does not exist for Fungi.

Which morphological characteristics are most influenced by the host matrix in downy mildews? : A case study in Pseudoperonospora cubensis [PDF]
, 2012 Before the advent of molecular phylogenetics, species concepts in the downy mildews, an economically important group of obligate biotrophic oomycete pathogens, have mostly been based upon host range and morphology.

Homoplasy as an Auxiliary Criterion for Species Delimitation [PDF]
Microorganisms, 2021 Homoplasy is a sort of noise in phylogenetic reconstructions, due to the accumulation of backmutations, convergent evolution and horizontal gene transfer (HGT), which is considered the major trigger of homoplasy in microorganism for its massive presence.

The art and science of species delimitation [PDF]
Current Zoology, 2015 Abstract DNA-based approaches to systematics have changed dramatically during the last two decades with the rise of DNA barcoding methods and newer multi-locus methods for species delimitation. During the last half-decade, partly driven by the new sequencing technologies, the focus has shifted to multi-locus sequence data and the ...

Exploring the Leaf Beetle Fauna (Coleoptera: Chrysomelidae) of an Ecuadorian Mountain Forest Using DNA Barcoding. [PDF]
PLoS ONE, 2016 BACKGROUND:Tropical mountain forests are hotspots of biodiversity hosting a huge but little known diversity of insects that is endangered by habitat destruction and climate change.

The hyperdominant tropical tree Eschweilera coriacea (Lecythidaceae) shows higher genetic heterogeneity than sympatric Eschweilera species in French Guiana [PDF]
Plant Ecology and Evolution, 2020 Background and aims – The evolutionary history of Amazonia’s hyperabundant tropical tree species, also known as “hyperdominant” species, remains poorly investigated. We assessed whether the hyperdominant Eschweilera coriacea (DC.) S.A.Mori (Lecythidaceae)
