Species Concepts and Species Delimitation
— The issue of species delimitation has long been confused with that of species conceptualization, leading to a half century of controversy concerning both the definition of the species category and methods for inferring the boundaries and numbers of species. Alternative species concepts agree in treating existence as a separately evolving metapopulation lineage as the primary defining property...
متن کاملGene flow and species delimitation.
A defining feature of species is that their constituting populations are connected by gene flow. However, interspecific gene flow (introgression) can affect species integrity. If some genome components were less prone to introgression than others, they should be particularly suitable to delimitate species. Recent simulation studies have predicted a negative correlation between intra- and inters...

متن کاملSpecies Delimitation and Global Biosecurity
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. Here we outline a novel approach to species delimitation, "tip to root", for two highly invasive insect pests, Bemisia tabaci (sweetpota...
متن کاملSpecies delimitation in fungal endophyte diversity studies and its implications in ecological and biogeographic inferences.
The estimation of species diversity in fungal endophyte communities is based either on species counts or on the assignment of operational taxonomic units (OTUs). Consequently, the application of different species recognition criteria affects not only diversity estimates but also the ecological hypotheses that arise from those observations. The main objective of the study was to examine how the ...
